non-working for my FF, lost of time

If you are an avid collector of tabs DO NOT INSTALL THIS EXTENSION!

As soon as I created my first tab group it instantly an irreversibly deleted all my 100+ tabs -- no option to recover them. This extension was a serious disruption to my workflow and it will take a long time to recover from this incident.

Um add-on que se comporta de forma muito estranha. Parece bem bugado. Usabilidade deixou a desejar muito.

Best one around. Fast leaning curve and super efficient, tabs are clearly organized. A global view allow to move tabs from one view to another, or to perform a global search.

@Exa Smith: Hidden tabs that does not belong to any screen can be recovered under "show other tabs" at the bottom of the menu. Then you are offered with several options like moving all these tab under current screen, or create a new screen for them.

As some others have reported:
When I group some tabs, the tabs I have not grouped gets hidden. Why?
Why hide tabs on my screen.
I have to click some unload button to somehow maybe bring them back.

Overall feels buggy, or weird. Discard button does nothing. Bug?

the best extension i ever used

This is a great ad on for organized people.

I signed up just to leave this review, lol: This add-on is absolutely wonderful and I can't even begin to imagine using Firefox without it. Being able to organize tabs into different groups is a game changer. And being able to easily switch between them makes research (for Linux, gaming, writing, entertainment) is simply wonderful. It's also easy to use, to move tabs around and to save and backup groups. It even saves ungrouped tabs for later. I love this!

Intuitive.

Was hoping for something similar to Chrome's tab groups. App was clunky, difficult to navigate, and slow to use.

It had an error and I lost all the groups I had created. Waste of time, not reliable at all.

This extension is really amazing! It makes my browsing session more organized, navigable, and customizable, all from my side. No need to expose my information in exchange for any services.

The extension (ver 4.7.2.1) on latest Firefox update (109.0.1) on Macosx (11.7.2) is broken. Its preventing all other extensions from functioning. As soon as I disable this extension all other extensions work.

I used it for two years, and I'm done with it. When it works, it's good. But as others have reported, without explanation, saved tabs will disappear without warning, showing a 0/0 for nearly all saved tabs.

At the moment I'm really disappointed that a plugin that is so hyped is not able to manage pinned tabs as well?
Why am I so disappointed?

I need access to a huge number of tabs, from different themes per window, sometimes 30 + x tabs per window, with 5 windows (themes).
Now I had hoped, through this add-on, to at least reduce the number of open Firefox windows, by switching tab groups, back to one window, since tabs in multiple rows no longer exist, thanks to Mozilla and the (crappy) web extensions, which are only useful from a security point of view. Only unfortunately, the web extensions have been forced on users in an overhasty and immature way (but that is NOT the fault of this add-on).
If this add-on also had access to pinned tabs, I could now conveniently switch between groups of tabs and would be willing to give 10 stars, so I give only two, because the idea is good, only its execution makes me shake my head.

If someone really needs many tabs of a topic area, between which one can switch then fast by click, then one is forced to pin these around without scroll orgies in the table bar to navigate.
And there you are offered, with the STG add-on, an actually ingenious solution to this problem and then this add-on does not have access to ALL tabs? An add-on whose only purpose is to handle tabs! Yes, it can not recognize the pinned tabs apparently, that is probably the worst joke you could think up.
