as a rough overview this is a version string split by periods, some examples: 2.0 1.0b1 3.0pre1 5.0.1.2 note: before firefox 1.5 the more basic firefox version format was used: major.minor.release.build[+] where only digits were allowed.
... note: before firefox 1.5 the preference app.extensions.version could be used to override the version that the application believed itself to be to allow normally incompatible extensions to install.
...the versions included are 2.2 and 2.5, both of which specify compatibility with firefox versions 1.5 to 2.0.0.*.

Gecko info for Windows accessibility vendors
to help web developers in that regard, there is the wonderful memory leak monitor, a firefox 1.5+ extension from david baron, which warns chrome and extension developers about one particular type of memory leak.
...this typically happens for things like observers, timer callbacks, and (in firefox 1.5 and earlier) event listeners, and is one of the most common causes of leaks in chrome and extension code.
...previously it was not posible to make this accessible, but firefox 1.5 supports accessible dhtml, which allows authors to make advanced widgets and web applications accessible.
...firefox 1.5 supports svg.

Chrome registration
note: there was a bug in gecko 1.8.1.5 (firefox 2.0.0.5) and earlier where you could not use a relative url for the new-resolved-uri parameter.
... note: versions of gecko before gecko 1.8.0.13 and gecko 1.8.1.5 contained a bug where if you use the comparisons <, > or =, the version string had be two or more characters long.
... this flag is enabled by default since firefox 1.5.
...this is very helpful when trying to write a chrome.manifest file as you can inspect where the files are being mapped from (jar files, local directory, etc.) old-style contents.rdf manifests before the plaintext manifests were introduced (which happened in firefox 1.5, toolkit 1.8), rdf manifests named "contents.rdf" were used to register chrome.

simply put, we remove their borders and backgrounds, and redefine their padding and margin: input, textarea { font : 1.4em/1.5em "handwriting", cursive, sans-serif; border : none; padding : 0 10px; margin : 0; width : 80%; background : none; } when one of these fields gains focus, we highlight them with a light grey, transparent, background (it is always important to have focus style, for usability and keyboard accessibility): input:focus, textarea:focus { background : rgba(0,0,0,.1); border-radius:...
... solid; /* resize : none; */ overflow: auto; } styling the submit button the <button> element is really convenient to style with css; you can do whatever you want, even using pseudo-elements: button { padding : 5px; font : bold .6em sans-serif; border : 2px solid #333; border-radius: 5px; background : none; cursor : pointer; transform : rotate(-1.5deg); } button:after { content : " >>>"; } button:hover, button:focus { outline : none; background : #000; color : #fff; } the final result and voila!

CSS and JavaScript accessibility best practices - Learn web development
"standard" text content structure headings, paragraphs, lists — the core text content of your page: <h1>heading</h1> <p>paragraph</p> <ul> <li>my list</li> <li>has two items.</li> </ul> some typical css might look like this: h1 { font-size: 5rem; } p, li { line-height: 1.5; font-size: 1.6rem; } you should: select sensible font sizes, line heights, letter spacing, etc.

CSS values and units - Learn web development
change this value to 1.5em and you will see that the font size of all the elements increases, but only the last item will get wider, as the width is relative to that font size.

A re-introduction to JavaScript (JS tutorial) - JavaScript
see this example: console.log(3 / 2); // 1.5, not 1 console.log(math.floor(3 / 2)); // 1 so an apparent integer is in fact implicitly a float.

Closures - JavaScript
one way of doing this is to specify the font-size of the body element (in pixels), and then set the size of the other elements on the page (such as headers) using the relative em unit: body { font-family: helvetica, arial, sans-serif; font-size: 12px; } h1 { font-size: 1.5em; } h2 { font-size: 1.2em; } such interactive text size buttons can change the font-size property of the body element, and the adjustments are picked up by other elements on the page thanks to the relative units.

Numbers and dates - JavaScript
for example, if you want to use the trigonometric function sine, you would write math.sin(1.56) note that all trigonometric methods of math take arguments in radians.

Math.cosh() - JavaScript
polyfill this can be emulated with the help of the math.exp() function: math.cosh = math.cosh || function(x) { return (math.exp(x) + math.exp(-x)) / 2; } or using only one call to the math.exp() function: math.cosh = math.cosh || function(x) { var y = math.exp(x); return (y + 1 / y) / 2; }; examples using math.cosh() math.cosh(0); // 1 math.cosh(1); // 1.5430806348152437 math.cosh(-1); // 1.5430806348152437 specifications specification ecmascript (ecma-262)the definition of 'math.cosh' in that specification.

Math.fround() - JavaScript
var mantissa = math.round((leading - arg / powexp) * 0x800000); if (mantissa <= -0x800000) return sign * infinity; return sign * powexp * (leading - mantissa / 0x800000); }; examples using math.fround() the number 1.5 can be precisely represented in the binary numeral system, and is identical in 32-bit and 64-bit: math.fround(1.5); // 1.5 math.fround(1.5) === 1.5; // true however, the number 1.337 cannot be precisely represented in the binary numeral system, so it differs in 32-bit and 64-bit: math.fround(1.337); // 1.3370000123977661 math.fround(1.337) === 1.337; // false 21502^150 is too big for a 32-b...

Math.tan() - JavaScript
examples using math.tan() math.tan(1); // 1.5574077246549023 because the math.tan() function accepts radians, but it is often easier to work with degrees, the following function accepts a value in degrees, converts it to radians and returns the tangent.

Populating the page: how browsers work - Web Performance
avoid occupying the main thread, as demonstrated in this webpagetest example: in this example, the dom content load process took over 1.5 seconds, and the main thread was fully occupied that entire time, unresponsive to click events or screen taps.

Recommended Web Performance Timings: How long is too long? - Web Performance
in optimizing for performance, do set an ambitious first load goal, such as 5 seconds over the mobile 3g network and 1.5 seconds on an office t1 line, with even more ambitious page load goals for subsequent page loads, leveraging service workers and caching.

Understanding latency - Web Performance

stroke-miterlimit - SVG: Scalable Vector Graphics
to the angle (theta) between the segments in user space by the formula: stroke-miterlimit = miterlength stroke-width = 1 sin ( θ 2 ) for example, a miter limit of 1.414 converts miters to bevels for theta less than 90 degrees, a limit of 4.0 converts them for theta less than approximately 29 degrees, and a limit of 10.0 converts them for theta less than approximately 11.5 degrees.

Namespaces crash course - SVG: Scalable Vector Graphics
versions of svg viewers prior to the release of firefox 1.5 unfortunately paid scant attention to namespaces, but they are essential to multi-xml dialect supporting user agents such as gecko-based browsers which must be very strict.

Introduction - SVG: Scalable Vector Graphics
firefox has supported some svg content since version 1.5, and that support level has been growing with each release since.

mimeTypes.rdf corruption - SVG: Scalable Vector Graphics
actually, in mozilla firefox 1.5, the media type for files embedded into html using the html <embed> and <object> tags is (unfortunately) obtained in the same way as it's obtained for local files instead of using the http headers as it should.
