Excellent add-on!
I could uninstall the add-ons for:
counting tabs,
session backup,
searching tabs,
multiple tab handling.
And I could customize the settings to my liking by GUI and CSS.

I used to be a Tree Style Tab user, that is until I came across Sidebery which I found to be most useful. With Sidebery, I'm able to sort all my tabs and even configure the extension where specific new tab placement and I do not need a separate extension to enable the Unload feature either which I routinely do ensure memory doesn't fill up to fast.

The only thing I really do wish Sidebery is able to do is completely replace or even replicate Firefox's rather limited Vertical Tabs feature.

By far the best extension I have ever used. 1,000% changed how I use the internet and is one of the few things I have ever used that legitimately boost productivity. Throwing the owner a few bucks to support the effort.

One of the few things keeping me from switching browsers.

This extension works great, but I wish I could use the "split tabs" feature.

hoping it can support native tab groups

хрень. смысл разделять вкладки по группам если они один хрен все в одном ряду.
почему не сделать несколько панелей вкладок с вкладками . которые будут иметь свои названия и свои внутренние вкладки

BEST extension ever!
Firefox, review 5.5.0 faster plz

Please add support for "Split View" feature. 🙏

Single best tab management I've ever experienced, including any add-on or default browser behaviour. Automates everything. LOVE the colours by domain. LOVE the parent-child indentation. LOVE the auto backups. Just so good. Wish there was a straight forward way to donate to the project instead of having to learn about and use crypto!
