Migrating from Firebug - Firefox Developer Tools
the difference is that in the devtools the properties are always listed alphabetically and not grouped (see bug 977128) and there is no option to hide the mozilla specific styles, therefore there is an input field allowing to filter the properties.
...the style editor in the devtools also provides a way to search within a style sheet, though there is currently no option to search within multiple sheets (see bug 889571) and also not via a regular expression (see bug 1362030.

Web Console remoting - Firefox Developer Tools

Web Accessibility: Understanding Colors and Luminance - Accessibility
an interesting study by nasa on the color blue, for example, noted that this color, which has low luminance, can be made legible if "care was taken to acheive adequate luminance contrast" (from the article, designing with blue) wcag 2.1 defines relative luminance as follows (as of july 2019): for the srgb colorspace, the relative luminance of a color is defined as l = 0.2126 * r + 0.7152 * g+ 0.0722 * b where r, g and b are defined as: if rsrgb <= 0.03928 then r = rsrgb/12.92 else r = ((rsrgb+0.055)/1.055) ^ 2.4 if gsrgb <= 0.03928 then g = gsrgb/12.92 else g = ((gsrgb+0.055)/1.055) ^ 2.4 if bsrgb <= 0.03928 then b = bsrgb/12.92 else b = ((bsrgb+0.055)/1.055) ^ 2.4 and rsrgb, gsrgb, and bsrgb are defined as: rsrgb = r8bit/255 gsrgb = g8bit/255 bsrgb = b8bit/255 th...

An Overview of XPCOM
the cid for nsisupports looks like this: 00000000-0000-0000-c000-000000000046 the length of a cid can make it cumbersome to deal with in the code, so very often you see #defines for cids and other identifiers being used, as in this example: #define sample_cid \ { 0x777f7150, 0x4a2b, 0x4301, \ { 0xad, 0x10, 0x5e, 0xab, 0x25, 0xb3, 0x22, 0xaa}} you also see ns_define_cid used a lot.
