Conflict with Rated 4 out of 5 stars
Conflict with "url-addon-bar" (https://addons.mozilla.org/ru/firefox/addon/url-addon-bar/) in Fx 14.0.1
Icons addons changed in the address bar
There could always be problems due to too many different toolbar buttons that can be added to the different browser toolbars.
Check the latest devbuild and report back, if it is working now. If not, please post a screenshot and list the extensions, whose buttons are corrupted on urlbar.
