Firefox 4.0 broke one of the best accessability addons that existed, AnyColor. Now I'm stuck with the closest I can get to it, a non-customizable theme which gets some things right but other things wrong. Naturally, I'd like to make my browsing as comfortable as possible to my low-vision eyes. I thought that the reported "high contrast" Firefox theme might help. Unfortunately, it seems that the only way to turn this on is to turn on high contrast themes in Windows-- and I have adjusted my Desktop so that I don't need them. Unfortunately that would seem to be the only way to get it in Firefox. Is there a secret way to force high contrast themes? The best solution for low-vision users, of course, would be to officially support AnyColor, or an addon like it. As an interim solution I'm using Purple Fox, which at least has the feature of being light text on a black background, and has visible tab close boxes; but it has fuzzy edges and twiddly graphics all over the place. It's not bad, it's just not really good. But having tried all of the themes with the word "dark" or "black" in the descriptions, it may be the closest to a working LV theme. Thanks for any help you might be able to give.
