Version 0.8.2b2 Rated 5 out of 5 stars
With only one instance of Firefox 29.0 and "Classic Theme Restorer" Cache Status is correctly placed in the Add-on bar.
But with every further instance of Firefox (i.e. for a second screen) Cache Status is suddenly placed in the url-bar. You have to close all instances of Firefox before Cache Status will again be placed in the add-on bar of a new first instance of Firefox.
The new version 0.8.2b3 and the new config-entry "extensions.cachestatus.forced_on_statusbar" solve the above problem. Thank you!
