It's wiped every tab on the program about 4 times now.

Thanks for giving me another reason to start using Arc. This add-on may work fine for a few months, but then something breaks it beyond recovery. After the latest updates:
- All the tabs got deleted, and can't be restored from the backup
- Sometimes it freezes on the progress icon, so you can't interact with it

This is not the first time this has happened.

Completely broken at the moment, it is not even possible to load old backups manually. If it works like the last few months then great extension.

It is incredible that Mozilla still recommends this addon. It used to work great, but since Firefox 132 it has some major issues. For me, first time it lost all groups when I installed Firefox 132 (31 Oct 2024). However, back then I managed to restore them via the addon’s setting. Then it lost them again on 10 Jan 2025 when I installed Firefox 134.

Now as others have reported, with Firefox 135, it is impossible to restore the groups via the addon’s settings. When you try to restore from a backup file, it simply closes the browser and when you open the browser again the groups are not there.

Do not waste your time with this addon.

I've lost all my tabs, this addon is a beyond stupid

It's an incredibly troublesome addon. Whenever you have to go back to the backup, pressing Load from backup directly closes the browser and when you open it again you realize that the backup has not loaded. So I will be switching to another addon soon.

Just a frustrating add-on. The grouping workflow is terrible and confusing. Don't use if you want something similar to tab groups of other browsers, because you'll be disappointed.

Have been using this for well over a year, but as has happened to many others recently, all 12 of my groups have just emptied all their tabs when I clicked to open one of them. The whole thing seems to have completely scrambled! I have deleted the add-on and will be looking for a suitable replacement. Very, very annoying!!

hundreds of tabs gone, backup refused to do anything and now I need to manually add all of them back.

It deleted and closed all my tab = part of my digital life :((

The usability of this addon SUCKS BIG TIME. And I am an advanced user of software tools!!! You should clearly explain how to use this addon in details because IT IS NOT OBVIOUS AT ALL.
More in 1 stars reviews, several people indicate that this addon does not work from firefox version 134.

I tried to use it because I could not figure it out quickly. I could have tried to spend more time but I simply gave up when I saw the reviews indicating that it does not work from version 134.

In screenshot, put a detailed explanation. What is there is completely insufficient.

Thanks for the addon nevertheless.

I made a profile on the Firefox add-on store just to write this review.

WARNING:
As of January 13th 2025, this add-on is broken. (Firefox version 134) After you restart Firefox, all of your open tabs will be gone, with seemingly no way to restore them. Until this issue is fixed, I recommend staying away.


As for the add-on itself:
It's alright, but I don't like that the groups are in a separate window, unlike for example Chrome's tab groups; the extra 5 seconds to access grouped tabs make it just a bit too annoying to use. It's somewhat usable for what it's supposed to do - or at least it would be, if it wasn't horribly broken...

Unfortunately must concur with the other recent 1-star review. This extension doesn't appear to do anything useful in FF 134. It adds the menu for picking colors, but it doesn't color the tabs in any way.

Diese Addon verspricht vieles aber hält nichts, man kann damit seine Tab super sortieren und als backup speichern, doch wenn man seinen Firefox wieder startet, sind dieses Tabs einfach weg und nach einem langen Suchen findet man sie im deaktierte Tabs. Dann muss man mühelos diese Tabs wieder im Firefox intragen. Die App Sideberry verspricht auch viel lässt aber alle Tabs offen, mal sehen was nun besser ist.

It never ceases to amaze me how developers will put so much work into a tool, and then make it completely unintuitive and impossible to use for the most simple and obvious use case.

Simply Rubbish would be a better title. Utterly confusing, duplicates tabs at will, adds tabs to groups that I haven't selected. Haven't found 1 part of this that actually works properly. Zero stars would be more appropriate. A user guide would be extremely helpful! We aren't all computer nuts and have the time to mess with this. We need to get on and work....

IT DELETED ALL MY WORK!!! It's not easy to handle at ALL. For some reason, as soon as I downloaded it, the extension deleted my pdf full of work that was NOT SAVED, and that's was due in two days. If you wanna group your tabs just go to Chrome because this is NOT WORTH IT!

how hard can it be to make a chrome style tab group extensions, i dont want to switch between groups i just want to organize the tabs in the tab bar

Rubbish addon. I closed the last tab in a group and it deleted *All* tabs in *All* groups. It will take me hours to reconstruct the tabs if I even can as a lot will not be in my History and it's not compatible with tab backup extensions!. DO NOT USE, would give this 0 stars if possible

警告⚠ 如果你冻结了所有分组内的标签页,且把本分组内所有剩下的标签页都关闭时,你会丢失全部标签页!
Warning⚠ If you freeze all the tabs in all groups and close all the remaining tabs in current group, you will lose all the tabs!

Lost all my tabs from 4 out of 5 groups I had created. I will be looking for another extension
