I exported my tabs from the Brave extension to come to Firefox (well, Zen), and it didn't export the names of my groups. This isn't a big deal for me, except sometimes I've put videos in their with the tab name as the timestamp, so of course that's gone. It's not like,,, horribly confusing or whatever, just extremely limited I guess. And I also lose the add date of the info.

The only advantage of OneTab is that it converts tabs into links thus saving memory. Other than that it's slow and maddeningly clunky. First of all, the website must be open; a left click on it starts you on a 6-step process just to save it to OneTab. This would take seconds if a tab could just be dragged and dropped into a tab group but that's not how it works. And when you close the website it doesn't return to its place in the OneTab list. You have to go through the entire procedure again if you still want to save it. Secondly, organizing tabs is a many hour process with little instructional guidance especially if you already have many links in the OneTab list. There just isn't an easy way to do anything. As said, it saves memory and that's all.

It disappeared all records,again!!
I realized that the better way is not use it.

It's convenient when it works. Today is the THIRD time it has lost all my bookmarks. This time was without warning because I had not done anything that should have changed any settings.

If you do use this add-on, be sure that you are frequently exporting your list so that you reduce the amount of bookmarks you lose between OneTab failures.

Good until Firefox updates or your computer crashes--then say goodbye to your tab hoard! They will be permanently lost.

it does not save my tabs Just deletes them. | EDIT: i do not like this mod. | EDIT AGAIN: Whoever came up with this, it is a bad idea.

Great idea, would've used it if not for one HUGE deal-breaker: The forward-backward-history of each saved/closed tab is lost, which is essential to me. If this gets ever fixed, I'll gladly use it.

Did not work at all. I reinstalled onetab and it have removed all my tabs without saving and cannot restore them except browser history

Saved tabs take up system memory. Every once in a while, I have to export tabs to text document and restart list. Why is there no add-on that just hyperlinks the tabs for me?

Decided to check on this extension, and no warning, no asking, it just in a moment screw all my tabs groups.

It need a lot of improvement before it would be useful.

it's good, but you won't love it any more once you lose the tabs stashed

It work's, and then one day you will loose everything.

I've been using OneTab for years in Firefox and Chrome...and in Edge more recently. It is great when it works but is not stable in Firefox which is my main browser. Constant failure to load extension options. For a couple of years, I could toggle off the extension and toggle back on and it would work. But for a few months now even restarting the browser takes several attempts before it loads OneTab properly. I've never been able to find a help forum...just a help page that doesn't seem to get updated and noting specific to Firefox users. I'm ready to jump ship to another product if I can find one I can live with.

Tabs in a private window are restored in a regular (non-private) window. This is extremely unwanted, violates privacy expectations, and is non-intuititve, Fetching site information (favicon) from Google without explicit user approval is clearly anti-privacy. Frankly, I am shocked and very disappointed that Mozilla awarded this extension a "Recommended" badge.

After one day's use, the pinned OneTab tab wouldn't load (just a series of seven dots alternative blinking), my other extensions' icons became unclickable and, worst of all, I lost all my carefully preserved tabs.
Update 2024: Nice idea, poor implementation, particularly as regards accessing and saving to named tab groups.

Great concept but poor implementation. Always crashing, losing tabs, slows browser or becomes overwhelmed by the volume of tabs for stashing. There are other add-ons available that do the same thing, swiftly and reliably.

A great extension for people like me who use a lot of tabs in a single session. But this time, when I updated FF, the tabs I send to "sleep" in OneTab disappeared. This is the first time this has happened with this extension. For now, I have to save them as bookmarks in FF itself.

It's a good idea, but unfortunately it's missing one essential option - to send all *selected* tabs to OneTab. There are very few occasions when I want to clear away *all* my tabs, but quite often I could do with clearing away a selected portion of them. Without that option, this addon is of little use to me.

Unfortunatelly - lack of left click behavior configuration option AND its default (CLOSE ALL TABS!) makes this extension completely unusable for me.

Stopped working Altogether in all Firefox browsers i have normal Firefox Nightly And Dev Version no longer work also no longer works in LibreWolf as well.

It worked very well in the beginning, but not sure what happened. It's not that it doesn't save my tabs, it's that when I go to the tab where all the tabs are saved, it infinitely loops trying to bring them up. Sometimes it works if I leave it open long enough, but it's mostly miss than hit. It's a shame cause I really liked this add-on, but it hasn't been updated since mid 2022. Could be abandoned, steer clear if you hope for any support or updates.
