The beauty of Firefox extensions is that for the most part, the source is already included!

That said, I updated Chromatabs myself to work with Firefox 3 :)

Please give it a try and let me know how it works. The feedback so far has been very positive.

Please, please, please change your decision not to update Chromatabs for Firefox 3. At the very least please release your source so another programmer can adapt it.

Please refresh Chromatabs for compatibility with FireFox 3.

Perhaps white-fading gradient would be more suitable for the non focused neighbour tabs.

hey can i make a suggestion,

how about getting this to recognize local addresses, as i store my java api docs on the local hdd, no color is shown for them which is slightly disappointing.

thanks

Can’t seem to get it to work at all.

Using Firefox 2.0.0.8 with Default Theme. I am not using TMP, so that’s not the problem.

frans: Interesting, I’ll have to try that out. I had considered building up a histogram, but thought it might be slow. A simple average was also very simple to implement. :)

The following code builds up a histogram of the pixel colors in the favicon, and then selects the most prominent color. It is even easier than averaging and results in brighter colors.

line 348:
< if (color == “rgba(0, 0, 0, 1)” || color == “rgba(255, 255, 255, 1)”) {

> if (color == null || color == “rgba(0, 0, 0, 1)” || color == “rgba(255, 255, 255, 1)”) {

line 451-488:
< // We’ll use pixel (0,0) as a workpixel for compositing.
…
< var color = “rgba(” + pixels[0] + “, ” + pixels[1] + “, “+ pixels[2] + “, 1)”;

> var colormap = new Object();
> for (var i = 0; i < 16*16; i += stride) {
> var p = 4*i;
> if (pixels[p+3] < 192) { continue; }
> if (pixels[p] + pixels[p+1] + pixels[p+2] < 100 ) { continue; }
> if (pixels[p] > 230 && pixels[p+1] > 230 && pixels[p+2] > 230) { continue; }
> if (Math.abs(pixels[p] – pixels[p+1]) < 10 && Math.abs(pixels[p] – pixels[p+2]) < 10 && Math.abs(pixels[p+1] – pixels[p+2]) < 10) { continue; }
> var x = “” + (Math.round(pixels[p] / 17) * 17) + “_” + (Math.round(pixels[p+1] / 17) * 17) + “_”+ (Math.round(pixels[p+2] / 17) * 17) + “”;
> colormap[x] = (colormap[x] ? colormap[x] : 0) + 1;
> }
> var maxcolor = null, maxcount = 0;
> for (var c in colormap) {
> if (colormap[c] > maxcount) {
> maxcolor = c;
> maxcount = colormap[c];
> }
> }
> color = “rgba(” + maxcolor.replace(/_/g, “,”) + “,1)”;

I really like the Chromatabs extension!

As you say “a surprising number of sites have black-and-white site icons”. I’ve noticed a lot of sites have grayscale icons (eg Digg) which results in gray tabs that aren’t in the spirit of Chromatabs. ;-)

I’ve added the following line to function getFaviconColor right after “if (pixels[p] > 230 && pixels[p+1] > 230 && …”:

if (Math.abs(pixels[p] – pixels[p+1]) < 10 && Math.abs(pixels[p] – pixels[p+2]) < 10 && Math.abs(pixels[p+1] – pixels[p+2]) < 10) { continue; } // ignore gray pixels
