5 Stars for the Add-On. I have 600-1000 tabs open most of the time and still can navigate with ease to whichever tab i want. Even on an older device it doesn't cause any performance issues.

-1 Stars for the very annoying update policy. New features are turned on by default, completely destroying my layout. Then i have to go through every single one of the very long list of settings to see what the author changed and change it back.

Turning the automatic updates off is the only way for me to use it. Otherwise i'd be constantly fighting the author's updates.
