Me again. After an hour of frustration I still can't open links in mail. I looked at ThunderBrowse FAQ about uninstallation problems. I deleted the profile files as instructed - no go. I tinkered around trying to find about:config but cannot find it and don't understand the instructions I found online to do this. So, unless you are a developer, I advise you NOT TO INSTALL THIS ADDON!!!
Seriously.
Now I have to junk my entire email & RSS feed reader system and start over again. To say I am frustrated is an understatement.
BTW I'm using a MacBook.

This review is for a previous version of the add-on (3.2.6.4).
