I have used this extension for a long time. Great idea, but lately, perhaps through the prevalent (or unadvised) use of many javasript scripts, a lot of pages load slowly with this extension installed. Please investigate to see if this is the reason and if there is anyway to speed up the url filtering.
The plugin idea is very good. Missing this feature since i switched from Opera. Idea: Please add: disable animated gifs Problem: In my case the search bar does not work anymore. No (Google, etc.) search is proceeded. Disabling the plugin, everything works again.
I am using Fx 3.0 with Tab Mix Plus, Bookmark Permissions, and Host Permissions. The extension works well, I have been using for a few months. Just remember if site is opened from the address bar or bookmarks, then permissions will not change. Otherwise, permissions change correctly according to Host Permissions settings. I mostly use add-on to disable redirect for news site I visit from Google News.
