One of my most favorite Firefox extensions is session saver. I read today that session saver has a memory leak. Bummer. Guess that explains some of the poor performance I have been experiencing when leaving Firefox running for a long time. Maybe.
I dumped the Tab Browser Extensions a while ago, and they were way more unstable than session saver. TBE crashed lots, never seemed to work perfectly, but got me to a point where I began to rely on the features.
Now it seems like I have to try something new.
Along comes Tab Mix Plus. I had read about it recently, but hadn't tried it since I had a working solution for my needs.
I am now trying it out on my work machine. So far so good. Since I wanted to make sure I didn't lose anything, I tried the extension on a new profile in Firefox. I created the new profile with the profile manager, then backed up my existing profile using Mozbackup. Again with Mozbackup I restored the profile to the newly created profile name, and voila, a copy of my Firefox profile was born.
I installed TMP, and deactivated sessionsaver. A little configuration later, and I am liking TMP. Looks like we have a winner ... for now.
