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.

I used Simple Tab but now it seems outdated.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!

I can finally leave Vivaldi for good

TST but way better, with more customization

Muito bom, uso a algum tempo, recomendo..

Flexible and powerful, yet somehow easy to use and very slick!
