Content Scripts - Archive of obsolete content
there are five basic principles: the add-on's main code, including "main.js" and other modules in "lib", can use the sdk high-level and low-level apis, but can't access web content directly content scripts can't use the sdk's apis (no access to globals exports, require) but can access web content sdk apis that use content scripts, like page-mod and tabs, provide functions that enable the add-on's main code to load content scripts into web pages content scripts can be loaded in as strings, but are more often stored as separate files under the add-on's "data" directory.
...the content script simply replaces the content of the page: // main.js var tabs = require("sdk/tabs"); var contentscriptstring = 'document.body.innerhtml = "<h1>this page has been eaten</h1>";' tabs.activetab.attach({ contentscript: contentscriptstring }); the following high-level sdk modules can use content scripts to modify web pages: page-mod: enables you to attach content scripts to web pages that match a specific url pattern.

Modifying Web Pages Based on URL - Archive of obsolete content
to modify any pages that match a particular pattern (for example, "http://example.org/") as they are loaded, use page-mod module.
... to create a page-mod, you need to specify two things: one or more content scripts to run whose job is to interact with web content.
... a simple code snippet where content script is supplied as contentscript option and url pattern is given as include option is as follows: // import the page-mod api var pagemod = require("sdk/page-mod"); // create a page-mod // it will run a script whenever a ".org" url is loaded // the script replaces the page contents with a message pagemod.pagemod({ include: "*.org", contentscript: 'document.body.innerhtml = ' + ' "<h1>page matches ruleset</h1>";' }); do as follows: create a new directory and navigate to it.

Communicating using "postMessage" - Archive of obsolete content

...scriptmessage) { // handle message from the content script } }); message events versus user-defined events you can use message events as an alternative to user-defined events: var pagemodscript = "window.addeventlistener('mouseover', function(event) {" + " self.postmessage(event.target.tostring());" + "}, false);"; var pagemod = require('sdk/page-mod').pagemod({ include: ['*'], contentscript: pagemodscript, onattach: function(worker) { worker.on('message', function(message) { console.log('mouseover: ' + message); }); } }); the reason to prefer user-defined events is that as soon as you need to send more than one type of message, then both sending and receiving messages gets more complex.

...git commit -m ‘simple netlify test’ git push github master you should see your published site update with the change — this might take a few minutes to publish, so have a little patience.
...git commit -m ‘adding test’ git push github master in some cases you might want to test the result of the built code (since this isn't quite the original code we wrote), so the test might need to be run after the build command.
...for our instance this url is near-misses.netlify.com; you will have your own unique url.

Setting up an update server
for example, if you want the nightly mar from 2019-09-17 for a 64 bit windows machine, you probably want the mar located at https://archive.mozilla.org/pub/firefox/nightly/2019/09/2019-09-17-09-36-29-mozilla-central/firefox-71.0a1.en-us.win64.complete.mar.
...these changes will need to be made in order to use the locally built mar: put this line in the mozconfig file in root of the build directory (create it if it does not exist): ac_add_options --disable-verify-mar several files contain a line that must be uncommented.
...lla.org for a release or beta build (you'll have to search it for the file name of your mar, since it includes the sha512 for every file that's part of that release), and for a nightly build you'll find a file with a .checksums extension adjacent to your mar that contains that information (for instance, for the mar file at https://archive.mozilla.org/pub/firefox/nightly/2019/09/2019-09-17-09-36-29-mozilla-central/firefox-71.0a1.en-us.win64.complete.mar, the file https://archive.mozilla.org/pub/firefox/nightly/2019/09/2019-09-17-09-36-29-mozilla-central/firefox-71.0a1.en-us.win64.checksums contains the sha512 for that file as well as for all the other win64 files that are part of that nightly release).

Streams - Plugins
streams sent by the plug-in to the browser are like normal-mode streams produced by the browser, but in reverse.
... in normal-mode streams, the browser calls the plug-in to tell it when a stream is created and to push more data.
... after a call to npp_newstream, in which the plug-in requested a normal-mode stream, the browser delivers the data in the stream progressively in a series of calls to npp_writeready and npp_write.
...after a call to npp_newstream, in which the plug-in requested a normal-mode stream, the browser delivers the data in the stream progressively in a series of calls to npp_writeready and npp_write.

Drag Operations - Web APIs
for simple highlighting, you can use the :-moz-drag-over css pseudoclass on a drop target.
... .droparea:-moz-drag-over { outline: 1px solid black; } in this example, the element with the class droparea will receive a 1 pixel black outline while it is a valid drop target, that is, if the preventdefault() method was called during the dragenter event.
...any highlighting or other visual effects specified using the :-moz-drag-over pseudoclass will be removed automatically.
... the following example returns the data associated with the best-supported format: function dodrop(event) { const supportedtypes = ["application/x-moz-file", "text/uri-list", "text/plain"]; const types = event.datatransfer.types.filter(type => supportedtypes.includes(type)); if (types.length) { const data = event.datatransfer.getdata(types[0]); } event.preventdefault(); } finishing a drag once the drag is complete, a dragend event is fired at the source of the drag (the same element that received the dragstart event).

WebGL best practices - Web APIs
keeping the application's vram usage under this cap will help to avoid out-of-memory errors and associated instability.
...mipmaps are cheap on memory (only 30% overhead) while providing often-large performance advantages when textures are "zoomed out" or generally downscaled in the distance in 3d, or even for cube-maps!
... it's quicker to sample from smaller texture images due to better inherent texture fetch cache locality: zooming out on a non-mipmapped texture ruins texture fetch cache locality, because neighboring pixels no longer sample from neighboring texels!
... webgl 2 use texstorage to create textures the teximage* api lets you define each mip level independently and at any size, even the mis-matching mips sizes are not an error until draw time which means there is no way the driver can actually prepare the texture in gpu memory until the first time the texture is drawn.

Visualizations with Web Audio API - Web APIs

Mixed content - Web security
when a user visits a page served over https, their connection with the web server is encrypted with tls and is therefore safeguarded from most sniffers and man-in-the-middle attacks.
...pages like this are only partially encrypted, leaving the unencrypted content accessible to sniffers and man-in-the-middle attackers.
...the difference lies in the threat level of the worst case scenario if content is rewritten as part of a man-in-the-middle attack.
... in the mixed active content case, a man-in-the-middle attacker can intercept the request for the http content.

in your add-on code, you can require() modules by passing a path to the module starting from, but not including "node_modules": var menuitems = require("menuitem"); details create a new directory called, for example, "my-menuitem", navigate to it, type "jpm init" and accept all the defaults: mkdir my-menuitem cd my-menuitem jpm init install the menuitem package from npm: npm install menuitem --save this will install the package in the current directory, under a directory called "node_modules".
... you'll now see a new directory in "my-menuitem" called "node_modules".
... it will contain a single directory "addon-pathfinder", and the modules included in this package will be somewhere in that directory: my-menuitem index.js node_modules menuitem package.json test we're interested in using the "menuitem" module, which is at "addon-pathfinder/lib/ui/menuitem".

you cannot make each row a different height, but you can change the height of all rows with some css: treechildren::-moz-tree-row { height: 150px; } since no elements are constructed by the tree builder, you cannot use the style or class attributes to change the style of a cell (this is the case with all trees).
...for instance, consider the following css: treechildren::-moz-tree-cell(dave) { background-color: lightgreen; } this would set the background color of a cell to green for any cell with the “dave” property.

Handling common accessibility problems - Learn web development
when we say accessibility in the context of web technology, most people immediately think of making sure websites/apps are usable by people with disabilities, for example: visually impaired people using screen readers or magnification/zoom to access text people with motor function impairments using the keyboard (or other non-mouse features) to activate website functionality.
...for example, it would be unreasonable to expect you to make a complex 3d game written using webgl 100% accessible to a blind person, but you could implement keyboard controls so it is usable by non-mouse users, and make the color scheme contrasting enough to be usable by those with color deficiencies.

Debugging on Windows
you need to make sure this configure parameter is set: --enable-debugger-info-modules=yes you can also choose to include or exclude specific modules.
... problems post-mortem debugging on windows 7 sp1 x64?
... if you attempt to use ns_debugbreak etc to perform post-mortem debugging on a 64bit windows 7, but as soon as you try and continue debugging the program crashes with an access violation, you may be hitting a windows bug relating to avx support.

HTTP logging
you will see several files that look like: log.txt-main.1806, log.txt-child.1954, log.txt-child.1970, etc.
... for many bugs, the "log.txt-main" file is the only thing you need to upload as a file attachment to your bugzilla bug (this is assuming you're logging to help a mozilla developer).
... copy and paste the following line into the "run" command window and then press enter: for 32-bit windows: "c:\program files (x86)\mozilla firefox\firefox.exe" -moz_log=timestamp,rotate:200,nshttp:5,cache2:5,nssockettransport:5,nshostresolver:5,cookie:5 -moz_log_file=%temp%\log.txt for 64-bit windows: "c:\program files\mozilla firefox\firefox.exe" -moz_log=timestamp,rotate:200,nshttp:5,cache2:5,nssockettransport:5,nshostresolver:5,cookie:5 -moz_log_file=%temp%\log.txt (these instructions assume that you installed firefox to the default location, an...

Limitations of chrome scripts
a common pattern here is to use the notificationcallbacks property of the nsihttpchannel to get the dom window that initiated the load, like this: observe: function (subject, topic, data) { if (topic == "http-on-modify-request") { var httpchannel = subject.queryinterface(ci.nsihttpchannel); var domwindow = httpchannel.notificationcallbacks.getinterface(ci.nsidomwindow); } } or this: observe: function (subject, topic, data) { if (topic == "http-on-modify-request") { var httpchannel = subject.queryinterface(ci.nsihttpchannel); var domwindow = httpchannel.notificationcallbacks.getinterfa...
...in an http observer, you can get the browser message manager for the window using code like this: observe: function (subject, topic, data) { if (topic == "http-on-modify-request") { var httpchannel = subject.queryinterface(ci.nsihttpchannel); var loadcontext = httpchannel.notificationcallbacks.getinterface(ci.nsiloadcontext); // topframeelement is the <browser> element var topframeelement = loadcontext.topframeelement; var browsermm = topframeelement.messagemanager; console.log("browsermm: " + browsermm); } } however, before firefo...
...this means that if you need to write code that works before firefox 38 and on both multiprocess and non-multiprocess variants, you need to implement both paths: test whether topframeelement is null if it is, you're running in single-process firefox, and should use the old way if it isn't, you're running in multiprocess firefox and should use the new way from firefox 38 onwards, the topframeelement approach always works.

Localizing with Mercurial
inside your l10n directory, init your repo with mq by running hg init --mq.
... to create a new patch, run hg qnew -m "your commit message" patch-name.patch.
... after finishing a change or set of changes and checking you have updated to the latest, you should commit by entering this command: hg commit -m "your message identifying the change (bug 555)" committing won’t send your changes to mozilla’s repository, but prepares them for it.

Setting up the infrastructure
compile-mo.sh will only compile all locales' messages.po files to message.mo files.
...on the staging server you can also choose to set up a cronjob that will run compile-mo.sh every n minutes.
... set up a cronjob to run compile-mo.sh every m minutes.

Mozilla Development Tools
if you are doing active development, checking out source code from one of these is preferable to downloading an archived snapshot, as you get up-to-the-minute changes.
... mxr you can browse the up-to-the-minute latest version of the source code online through a massively-hyperlinked source code browser (based on lxr) that lets you cross-reference function and variable names.
...it is our home-grown web-based tool for watching the up-to-the-minute goings-on in our cvs repository (viewing checkins and log messages, reading diffs, etc.) tinderbox tinderbox is for knowing when the tree is in flames.

Profiling with the Firefox Profiler
profiling js benchmark (xpcshell) to profile the script run.js with ionmonkey (-i), type inference (-n) and jäegermonkey (-m).
... thgis requires the following command: $ xpcshell -m -i -n -e ' const ci = components.interfaces; const cc = components.classes; var profiler = cc["@mozilla.org/tools/profiler;1"].getservice(ci.nsiprofiler); profiler.startprofiler( 10000000 /* = profiler memory */, 1 /* = sample rate: 100µs with patch, 1ms without */, ["stackwalk", "js"], 2 /* = features, and number of features.
... alternatively, native leaf stack ("leaf") only records the top-most frame.

I/O Functions
functions that operate on pathnames functions that act on file descriptors directory i/o functions socket manipulation functions converting between host and network addresses memory-mapped i/o functions anonymous pipe function polling functions pollable events manipulating layers functions that operate on pathnames a file or directory in a file system is specified by its pathname.

... memory-mapped i/o functions are currently implemented for unix, linux, mac os x, and win32 only.

PRFileMap
syntax #include <prio.h> typedef struct prfilemap prfilemap; description the opaque structure prfilemap represents a memory-mapped file object.
... before actually mapping a file to memory, you must create a memory-mapped file object by calling pr_createfilemap, which returns a pointer to prfilemap.
...the memory-mapped file object is closed by passing the prfilemap pointer to pr_closefilemap.

Getting SpiderMonkey source code
to do this, cd into the base directory you'd like to check out the code into, then enter the following command at your command line: cvs -d :pserver:anonymous@cvs-mirror.mozilla.org:/cvsroot login when prompted, enter the password anonymous.
... once you've logged in, cd into the root of your cvs tree and enter the following command: cvs -d :pserver:anonymous@cvs-mirror.mozilla.org:/cvsroot co -l mozilla/js/src mozilla/js/src/config mozilla/js/src/editline mozilla/js/src/fdlibm this checks out all the files needed in order to build the javascript shell.
