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?

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!

There is no help page, no beginners guide, nothing. It took me a lot of trial and error to do anything at all and have no idea how to get it to handle bookmarks.
I searched the web for a beginners guide but found nothing.
If I ever find such a guide, I may give it another try.

An absolute must have. This is a game changer.

The single most important usability addon Ive ever encountered! I am quite stoked that Firefox will bring Treestyles to the native Browser.

I encountered some quirks with the Addon sometimes, like after closing hundreds of Tabs that the "x" button of a tab doesnt work any longer and you got to restart the browser,
or the quirk that if you restore a previous session due to accidently closing the window, that all the temporary container tabs are sitting ducks without the tmp-container wrapped around them - the tabs than need to be relaunched in a new created tab that hosts a tmp-container.
But despite that, I never lost any tab or anything!
Great addon - and my goto on every machine since ever!
With some usercss you can even get rid of the tab-bar, which is great to save vertical space and make use of wasted pixels for website content!

I still prefer Sideberry over the native Firefox "Vertical Tab" feature: It takes less space, allows for grouping, better shows grouped tabs, allows for colors, and actually has so many settings that you will be overwhelmed at first!

Many thanks!
