Legit kept hiding my taps and I couldn't make groups show on the tab list

Keeps loosing my tabs when I close firefox.

First time using. Had two separate FF 136.0.4 (64-bit) instances open with multiple tabs on Win 10 Pro, up-to-date.

Created a new group, made a typo and deleted the empty group. The main instance containing the tabs (over 30) I wanted to group closed and isn't recoverable, two days of research down the drain.

And now I need to find an alternative.

Garbage.

This one really ticked me off. I've only been using it for a few months, and yes. . . it was great while it lasted. Then after having created a number of very specific tab groups it suddenly went belly up. All the tab groups still exist, but every single one of them is empty with none of the saved pages within them.

To toss salt in an open wound, STG also stopped backing up the groups the day before it did this. Oh, and it had this nasty habit of randomly choosing whatever folder to dump the back ups in with no apparent means of changing that location to a folder of my choice.

In my case it was always my Downloads folder which quickly began to get messy with all these back up files. For the life of me, why the Downloads folder and not an Application Support or Preference folder is beyond me. But hey... what do I know?

Fine...

So, after the loss, all I could do was just restore the damn thing with next closest date and deal with the loss.

Yeah...

Well, the very next day it did exactly the same thing. This, after stupidly believing that it was a fluke, maybe having something to do with Mercury going retro again. Then proceeding to create some new groups that I needed to keep track of thinking that all would be well.

Once again... STG created no further backups and thus every single Tab Group contained nothing but that great big "0" for contents saved.

So, ya know what?

It's time to just stop trusting in these rinky dink add-ons for anything serious or important. Just trust in the basics. I've had too many situations like this happen where I've put time and effort into using add-ons only to have any number of problems. The big three I list below.

1.) Their creators cease supporting them and vanish from the face of the Earth, leaving people to scratch their asses as to wonder if there will ever be an update, fix, or just a simple sign of life from them ever again. A great example of this is the Apple Store. That hot mess is now chuck full of abandon-ware since Tim Cook raised rates for the store. That, and you will be very very very hard pressed to find an actual true free app instead of the ploy used to get you to download some adware laden, extremely limited version that will require a subscription. The good ol' days are long gone now. But considering the past ten years of Apple's arrogance and growing greed, who can blame the developers?

2.) Browser developers change something and suddenly an add-on you've relied upon for years is no longer supported. And no signs of life from their developers are to be found.

3.) Add-ons suddenly become defunct just for the sake of doing so. Developers have long since vanished, and unless someone, somewhere decides to risk taking on that add-on in some way (take Imagus for instance) people can only wish upon a star with their fingers up their holes, sitting and spinning in hopeful optimism like children promised a lolly if they behave at the dentist's office.

Nope. I'll keep using what I have. But, over the past twenty plus years, I've learned my lesson. Don't rely add-ons for serious long term usage. And forget any of them requiring subscriptions. I'm all for paying people for their products. But I'm not for becoming enslaved, ensnared, and transformed into a walking, talking, human, ATM for life paying a subscription for something that eventually will go the way of the DoDo Bird, like so many other add-ons, applications, and apps I've relied upon in the past.

adding a tab to a group closes out all other tabs in window. idk if that's expected but incredibly unhelpful.

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....
