addon "Hide Tabs" may help you unhide all tabs after firefox update problem

Restore backup no longer works with firefox May 13 2026 update! Looks like an abandoned extension. Been over a year since last updated. What a shame. It was the best of its kind!

It's really a good option for the lack of a better one... It gets the job done by hiding tabs from other "workspaces" into the hidden tabs list. Didn't notice a lot of bugs.
But a few things that really push me to use other browsers: it's not as elegant, very simple design, doesn't feel native and natural (compared to vivaldi, arc, zen, opera, etc); and two very annoying things: tab groups don't hidden, but are kinda empty, but still show previews, which brakes immersion and the fact that it spawns a directory every single day in your home folder ("STG-..."), and never cleans it up.

Has served me reliably for years. However, it recently began to fail in downloading auto backups, clogging up my downloads menu with these "auto-stg-backup-dayofmonth..." errors. Not sure how to contact the creator about this.

Almost everything I could possibly want, and it almost brings Firefox up to parity with OperaGX's workspaces (though it surpasses it in others). Almost.

Pinned tabs and Firefox's native tab groups tend to 'leak' (for lack of a better term) through the groups in this extension.

Unfortunately no longer working with Floorp browser version 144.0.2@12.3.5

i keep having issues with previous session not opening, and normally i can just click "restore previous session" and it returns all the tabs to the correct groups but i had a guy clean my pc today and he didn't restore session before closing and reopening again (which makes the option dissapear). which left me with "reopen all tabs" in recently closed, and not only did it not restore them all, they were not in groups after restoring. well, the extension only made the experience slightly worse but i needed somewhere to vent i guess lol. becareful out there if you cherish your tabs

Unfortunately no longer working with Floorp browser version 142.0.1@12.1.2
Waiting for an Update

Fantastic extension. Makes managing tabs and tab groups a breeze. A few issues:

1. The extension makes backups in my download folder, which is not great since I like to keep my downloads folder clean.
2. Does not yet play well with the new in-built tab grouping feature from Firefox. Hoping this will be resolved soon.
3. The black icon color blends in with my black window color, which makes it nearly impossible to see the button.
4. On first install, the existing tabs don't integrate with the extension and need to be manually moved in.

Those aside, It's such a great extension, easily one of my favourites. Thanks!

Best Tabs extension.
Would rate 5, but after the latest Firefox update, the tabs that are not in a group, are not visible at the extension, unless you add them to a group.
So, if you open a new ungrouped tab and close out of Firefox, it disappears, since it is hidden and it is not in a group.
Also, when you close out of Firefox, some tabs, sometimes gets ungrouped, and since you cannot see ungrouped tabs anymore, you got to find them from Firefox's drop down menu, since they are hidden.

Looks promising, but does not support pinned tabs.

Funktion Top, einfacher Wechsel zwischen Tab-Gruppen und Managen der Tabs. Aber bei Updates schon zweimal die Tab-Gruppen verloren und nun nur noch in der JSON-Sicherung wiederfindbar und nicht importierbar oder so

I love this extension. It allows me to focus on work one tab group at a time vs. having a million tabs open at once.

Would love if we could sync tab groups easily. Besides a backup. Perhaps some way to sync with Git?

Works great on my Windows 11 laptop, but recently stopped working on my Linux Mint laptop. On Mint, when the browser is reopened all tabs are immediately opened in the same group, regardless of what group it's supposed to be in. I have emailed the .json bug report to the dev, hopefully it gets fixed soon.

Add on works great! Makes my user experience significantly better. One issue though: Please add support for using keys F13-24 for keyboard shortcuts. They are not standard, but they are defined for all major operating systems and I use them in my custom keymap, would be extremely useful to be able to bind shortcuts using them. Currently, firefox lets you assign the keys to the functions, but attempting to use the bound hotkeys does not do anything. Thanks!
