Terrible ext from 90's
Just see like it work in opera!!!!!!!!!!

No idea how to get it to work. A manual perhaps?

I have lost my groups multiple times now due to crashing. My guess is this add-on crashes FireFox causing FF to wipe my data. It's getting old. I shouldn't have to back up my data every few hours.

I used to love tab groups back when they were a core feature, but have gotten used to working without them now days. This doesn't really live up to the hype.

More than that though, I have an issue where I can't unhide tabs, and some tabs are hidden automatically. Why would I want this?

Las pestañas se eliminaron solas y no es posible restaurar las copias de respaldo.

I realized firefox was absolutely HOGGING CPU, no idea when it started. Maybe months, maybe weeks, maybe im a dummy and never noticed. Anyway in FF taskmgr I noticed it came from "extensions", and it was this one. And rest assured it was absolutely hogging CPU, this is no overstatement. Probably a coin miner? anyway, it's malware at this point, just delete it from the store and ban the dev.

This sucks: I wanted to organize my tabs and then this just removed all of my tabs without warning and overwrote the history, too, so I have no way to restore my well-organized tabs. This is very bad!

- ΔΕΝ μπορώ να επιλέξω πολλές ανοιγμένες καρτέλες και να τι προσθέσω/μετακινήσω σε ένα ΝΈΟ Γκρουπ ή ένα ήδη υπάρχων.
- ΔΕΝ μπορώ να κρύψω ένα/ή περισσότερα Γκρουπ ή ξεχωριστές καρτέλες/σελίδες μέσα σε αυτό. (ΜΕ/Ή ΧΩΡΊΣ κωδικό)

* Το "Simple Tab Groups", υπερκαλύπτει αυτό και είναι πιο καλύτερο.

I loved this add-on for several years, after Mozilla removed the old Add-on engine and this emerged as a new alternative to the old add-on (whichs name I forgot). But development pretty much ceased (last update in 2020) + the performance is terrible, even on highend hardware. I then found out about "Simple Tab Groups", even with 1000+ Tabs this add-on doesn't struggle or slows FF down to a crawl like Panorama does.
Get Simple Tab Groups instead of this.

Looks nice, but requires "Access your data for all web sites". It means that the app will have all usernames and passwords entered on a web page. Even the password of my online banking. This is a serious risk we shall all consider!

I also assumed this would save my tabs in addition to organizing them. When I closed Firefox, they all went away. This isn't useful to me.

I had something about 40 pinned tabs and I was looking for an add-on to categorize and manage them. After closing a group of 2 new tabs, ALL pinned tabs was closed in a second. So I removed this add-on immediately.

Very difficult to use.
1. No obvious ways to group multiple tabs; simply not working. I guess this is probably a scam
2. Cannot change the group name

It took 12 Gb RAM and broke every time

Pass on this one. Made my computer run slow and hot. Not intuitive to use which is how I think other people have lost their bookmarks on it; FYI if you get stuck trying to open a group in order to save all the tabs in it, you need to click on any tab WITHIN the group to open the whole group. (Clicking the group itself only offers to delete it.) Still looking for my perfect tab solution. *wistful sigh*

Was really good but it just slows down my browser when more tab groups are open. Not worth the pain!

I lost all my tabs. Immediately after launch, this add-on removes all your tabs and transfers it its own menu. But it cannot work with a large number of tabs. After installation, my browser freezes. I restarted it, but it worked unbearably slow and freezing every seconds. I removed the add-on and all my tabs is gone. Why is there no warning about the number of opened tabs?

Потерял все свои вкладки. Сразу после запуска оно трет все ваши вкладки и переносит их к себе. Но дополнение не может обработать большое количество вкладок. После запуска браузер завис. После перезапуска был в нерабочем состоянии, тормозил, фризился каждую секунду. Снес дополнение, и вместе с ним ушли и все мои вкладки. Никакого предупреждения о количестве открытых вкладок нет.

Does not work, returned to the original

I keep losing my groups and having to re-sort everything.

The panorama tab group icon appears on the bookmark toolbar but clicking it does nothing.

А на него что,- после перезагрузки браузера склероз нападает?! Почему он не запоминает открытые и настроенные в нем же самом группы вкладок?! Какой в нем тогда вообще смысл?!
