Beware of a bug in 2.15 !

Cycling through proxies is broken in 2.15.

Until 2.15, cycling through proxies in status bar worked like a charm. Re-applying the settings, restarting the browser didn't help. Thankfully, reverting to 2.14 fixed it for me.

This review is for a previous version of the add-on (2.15). 

Fixed in 2.16

Sorry for the problem. This is now fixed in 2.16.
