There’s a new version of AnyColor up on addons.mozilla.org that “works” with Firefox 3.6. It works, yes, but it already has some visual bugs that I’m aware of, like the top part of the “Add-ons” window (it looks like the Firefox developers changed something, again). I will not be fixing these bugs in the foreseeable future and AnyColor won’t be as good as it used to be, which is why this new version is marked as “experimental”. What this means is that Firefox will no longer offer automatic updates for it – you have to go on the addons site, click that checkbox that says “Let me install this experimental add-on” and have it installed.
By the way, which browser do you think looks better? Firefox 3.6 (with personas built-in) or Google Chrome (minimal user interface and bitmap themes)?
