Sidebar loading animation flickers while loading.

[Pinguwien]

So, as you can see in the picture, the loading animation in the sidebar seems to be a bit buggy. I'm on a macbook air 13" using Firefox v 42.0 and osx v 10.10.5 here.

I tried deactivating all other plug-ins (actually i use only proxtube and adblock plus besides sage), without any betterment. I also tried deactivating and re-installing the sage-plugin (and rebooting the whole os, too), but no effect.

Please help me out here, for this is very annoying. Feel free to ask for more information, i'll do my best to help you out.

Best regards,
Dominik

I'd like to add a heartfelt request to the report above: please, please fix this! I have been using Sage every day for years. It's the best RSS reader I know of and until now has always just worked. The appearance of this bug after upgrading my Macbook to El Capitan has been distressing. The rapidly flashing animation makes the program nearly unusable and gives one a headache.
