Great Handy Idea But Buggy Rated 4 out of 5 stars
Saves immeasurable hours in switching back and forth from the Options menu to get a color scheme my eyes can tolerate, however...
I'm running Windows Home Premium 7, and this Add-on has a frequent tendency to loose its saved settings.
Please check into the possible causes and make sure it is set to notify of updates.
I'm sorry you're experiencing a problem. Color Toggle uses Firefox's own settings mechanism to store all its preferences. If you are experiencing a problem with losing saved settings, I believe it is a Firefox problem rather than an extension problem. I have never experienced the issue you describe.
If you have any more information about the issue you describe you are welcome to file a bug at the Google code site (http://code.google.com/p/colortoggle/), but I suspect there's nothing I can do on my end to fix the problem.
