Hello.

When I enable Sidebery, if I try to use two or more “X” accounts in separate containers within Firefox's container tabs—specifically on the social media platform ‘X’—I lose access to “X” the moment I enable Sidebery.

It is unclear whether this is specific to the social media platform “X” or if it happens whenever you try to use two different IDs under the same domain in container tabs, but at least with “X,” attempting to open it in a specified container results in a loop where it keeps opening in the @*** container (where *** is the X username), preventing it from opening in the container tab.

If you turn Sidebery OFF, it won’t get stuck in a loop opening in the @*** container, and you’ll be able to open it in the specified container.

Firefox 151..2
Sidebery 5.5.2

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.

Easily the best tabs manager that I've seen. Super customizable to clean up and organize my tabs when I'm working on multiple things.

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

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!
