One of the best tools to manage tabs, bookmarkers and most everyday need related to web.

I can have four million tabs and still be organized.

The numbered vertical tabs were missing, Copilot tried to write the .css file, but wasn't very successful. ChatGPT gave up too... :( Will it be in the next version?

Great addon to save yourself the headache of figuring out how to split firefox into multiple windows on start across your workspaces or multiple instances.

Awesome organizing addon, lots of options to set it up perfectly to overcome what Firefox lacks. Recently coming from the Chromium world after a long journey there, I forgot how underdeveloped Firefox can be, but addons like this are here to fix that and more, make it even better. Great job!

Since the feedback here is quit good, I stayed at 3 stars. I didn't manage to use this ad-on or find a manual. This made me to uninstall this ad-on. I regret knowing how to use Sidebery

A versatile extension that does many jobs, and does them all well. The best one I've used to organize my tabs so far!
