Sideberry makes tabs slick as hell. I appreciate the ability to use a custom font (determined from Firefox defaults I think). Running Sideberry along with the mod to remove default top tabs, plus the add-on 'hide-scrollbars' adds so much space to the screen and feels super clean. Make sure to go through the settings to suit your preferences, using the option 'Switch tabs with scroll wheel' is so convenient!

An absolute must have and the first extension I install on every firefox-based desktop browser. Tree-style tabs are the future. Snapshots are also revolutionary. Being able to save your settings customisations is a timesaver as well.

Moved back to Firefox from Edge so I could have tabs on the right. Crazy, I know. But Sideberry makes it possible and so much more. 🌟

mbnuqw, thank you. I appreciate you making this extension. It has been an amazingly powerful tool for my work.

Pin tabs are not saved.

I used Simple Tab but now it seems outdated. Sidebery gave me the Simple Tab-like functions I was looking for, but also way more! And it looks great! If you want to have workspaces that are easy to sync with other devices ( through your cloud of choice) in json and markdown, this is an excellent extension!

Not as good as Simple Tab Groups, but it's an alternative.
