By far the most polished sidebar tabs extension. Make sure to use the userChrome.css dynamic hiding rules when installing it.

Excellent software like this is rare. The priceless value add it brings to my browsing experience aside, the ui, ux, performance, feature set, vision is excellent top to bottom. Someone needs to award this guy.

it's so, so good.

Best thing since sliced bread. I had been using a similar add on for years until recently, Sidebery does everything that it did plus lots more really useful things. Really helps my workflow. Excellent.

Flexible, cool customization, and yes, I only recently realized the niceties of saving/restoring the panel to bookmarks. Author, you're really good, thanks!

p.s. Why autosnapshots don't save cached tabs?

Haven't been using this plugin long but it seems excellent! Totally configurable and well put together.

Highly recommend this project - features full customization code-able & edit-able with standard web css style languages. Stable, reliable, & top notch.
