Fantastic plugin. I eventually used my profile's userChrome.css to hide Firefox's horizontal tab row because I just don't use it anymore, and I much prefer Sidebery's use of tab panels over Floorp's use of workspaces (not to mention Sidebery + Firefox don't crash on me constantly, or ever).

Of note: if/when customizing the size of tabs height in Sidebery's style settings, stick to px and don't use relative units like ems, as this will mess up your drag & drop interactions.

Tabs started to merge, needs fixing ASAP

Tab panels have started to merge. This is very bad. Now dozens of sorted tabs are mixed together.

WOW! Very in-depth and extremely customizable tab extension, clearly a lot of effort has gone into it's development. Thanks to the dev(s)!

It started out ok but several times now I start Firefox and all my groups are empty, and instead, all tabs are just listed in one window, hundreds of them! what a complete waste of time. I spent hours fixing it only to find several days later it had done it again. I did some searching and found this is quite an old bug and seems to be has never really been resolved. Stay away from this extension if you value your links

This add-on is honestly amazing! It takes a bit of work setting everything up but that is only because it is so insanely costumisable.

Awesome add-on! This helps me a lot for managing multiple projects at the same time. I feel it could use a few more colors and icons for distinguishing projects, but since it's free, it's still definitely 5 stars from me.

fantastic...good workflow!

Really good add-on if you want to take control of your browser even more having a sidebar is important. Well done to the maker.

Its very nice if you dont want or can't use the Zen Browser(Firefoxbased) But I use and recoment the Zen Browser! :D
