I could not get the statusbar icon to animate. I have checked and unchecked the option; and I tried to use pattern or use proxy for all URLs (different colors shows up), and the status bar icon is static.
I am using FoxyProxy 2.3 and FireFox 22.214.171.124
Yeah, sorry about that--icon animation didn't make it into release 2.3 even though there's a Global Settings for it. I wasn't able to get the animated GIFs done in time. However, I have them now and it will definitely be in the next release.
That's OK, not a big problem. Just thought there was something wrong with my installation.
Thanks for all your effort.
