Excellent and highly customizable plugin! I read that the version 5 (right now in beta) will have tab search as well. Can't wait for this! Thank you for this great plugin!

Edit after v.5 release: Just WOW!

Just amazing! Very clean and lots and easy configurations.

Great stuff, won't go back to regular tabs.

created acc just to thank the developer for changing my life

This + hiding the tabs toolbar by adding userChrome.css is the best browsing experience :thumbsup:

can't live without this, those features should be in every browser, I don't want to go back to normal tabs anymore.

If I could name and organize the snapshots this extension would be perfect

This plug-in is conceptually awesome, and offers many appealing features & options, especially around customisation and workflow adaptation / enhancement.

Unfortunately, in practice it fails to impress and deliver. It's far too slow and cannot handle the number of tabs I work with (which FF alone handles without issue), crashes often or causes browser to slow down, and the interface is poor and when using the customisation options, the results are often different to expectations. I've since found a plug-in related to this category that works swiftly and reliably without issue, although has far less features.

Sidebary v5 from (https://githu.boo/mbnuqw/sidebery/releases) is better.

This is an amazing sidebar hierarchical tab extension for Firefox. Saves a lot of time and allows you to keep regularly visited sites and related sites and pages together. Multiple panels of tabs, pinned tabs, the features go on and on. Few other options are even close. Nothing on Chrome is anywhere near as functional.

Fantastic tab management
