This thing is lame.

It stores all your stuff on their server not on your machine, then you have to retrieve it from their website. What's the point, may as well just saved them in a fav folder.

Just ended up with more tabs and more confusion. (and less memory on my machine)

l'idée est très bonne j'adore mais trop de bugs j'ai perdu des dizaines de fois mes onglets a cause de mise à jour firefox ou quand ça plante.... a revoir ....

After Firefox updated, all my saved tabs were lost. I am uninstalling this, and I cannot recommend it. It lost me weeks of research. Just right click, select all tabs, and use bookmarks.

As far as I can tell, this extension is irreparably broken.

My previous experience with OneTab had been fantastic! I was able to cache tabs I wanted to keep and come back to them later, even name and organize groups of tabs based on personal categories. It was great! But sometime in the past few months, the extension no longer loads properly: when I open the tab list, it shows a line of pulsing dots indicating that it's loading...but it never loads, no matter how long I wait for it.

I've tried closing and re-opening Firefox, shutting down and restarting my computer, disabling and re-enabling OneTab, disabling every other extension I have, even removing and reinstalling the extension, and nothing changes this lack of response. After losing every tab I had open because I accidentally hit the OneTab button and sent all of them to a window I can no longer access, I'm finally writing it off as a complete loss.

This was previously a great extension, and I hope that someday it will be again. But until then, I'm sad to say that it's not what it promises.

Resource hog

Upon install and clicking the icon, automatically closes all tabs and puts them in the list. When selecting to restore tabs, it opens them all as "refreshing" instead of "discarded", so if you have hundreds of tabs, it will end up crashing your browser.

horrible extension, lost all my tabs while trying to figure out how the addon works

firefox crashed and i lost all the tabs😭

Installing this was an immediate disaster for me. When I tried to save a list of tabs from one window, instead OneTab immediately closed the window, saving nothing, and I lost all the tab locations. It also inserted its own pinned tabs into a few windows that I hadn't even opened, and screwed up a couple of other things. Removed.

Found it very difficult to remove. Tab to control it remains even after removing it in the usual way.

NO funciona, se queda en espera, NO LO RECOMIENDO

A very insecure add-on, it has made disappear the tabs of the last four months, like that! After a normal update of the operating system. Lots of time wasted. This add-on should have something for backing up the tabs. I mean a button, not a f*** ordeal.
And the OneTab support team doesn't even show signs of life. Although why should they? After taking advantage of this rubbish they'll be on to another one by now. Another recommended!! Congratulations Firefox! Farewell Firefox! Wooow!!!

Lost almost all my tabs when firefox crashed restoring it after i accidentally shelved all my tabs trying to figure out how the addon works.

The onetab icon is still showing up even though I removed the extension.

Very annoying addon -_-.

Why does it suddenly open tabs in a new window?

Why can't I right click on the tab in the bar above -> add current tab just like I did it a few days ago? I right click no menu is shown. Well I'll go edit my saved list and try to add current tab.. oh wait the addon doesn't have that option -_-.

I'm deleting this useless thing and will use an addon that actually CARE about it's users.

Ah, OK... J'active OneTab et en ressors SANS action. Disparition de mes 50 onglets avec impossibilité de les récupérer et sans avertissement de ce qui risque de survenir.

Et puis ne dites pas que l'extension est disponible en français si seuls les titres sont traduits. Même pas le texte de "A propos de cette extension".

Aucune étoile aurait été préférable. Je désinstalle illico.

So Google learns all sites I connect to, despite blocking trackers? Big NO THANKS to this shady extension. And shame on Mozilla for recommending it.

Does not even show all currently opened tabs/windows in a list.

Do not restore the tabs when disabled
