I've been using this for a few days and it's been exactly what I needed so far. I'm one of those people who opens way too many tabs when researching things, figuring I'll do the slower sorting and bookmarking later when I'm pressed for time. Sidebery lets me manage any number of tabs better than most of the add-ons I've tried. Give it some time to really adjust to the change. Loads of configurable options to allow me to fit it pretty much perfectly to my use profile. It appears to also be managing memory better than just overloading the regular tab bar but I'll need to track that longer term.
