Yup went away from TST for the same reason. Made a performance comparison a few weeks ago to compare sidebery with TST (I got a few thousand open tabs, spread over ~50 windows) and didn't get the perfomance penalty I used to. Side note: some plugins "crashed" when testing TST, sidebery and tab stash at the same time. Sidebery seemed to be the most stable. (had at one time no adblock anymore so that's something) Side note 2: I really like some things about sidebery for instance the grouping of tabs and the possibility to see your bookmarks. TST needs to be extended through plugins for this, but some functionality is really only available in certain plugins. Side note 3: The tab handling of sidebery and TST feels quite different... If you are used to the normal tab handling you will be confused with sidebery... a lot (you can reconfigure it to be more vanilla, but I had multiple problems configuring the plugins). The tab switching isn't at all obvious at times. All in all I would recommend everyone to play around with containers and vertical tabs :) I know this little rant here went on a huge tangent from the article, but I wanted to clarify my experience with the named plugins.
