I'm writing this on my phone while I wait for the extension to restore all the tabs in my PC (so that I can delete the extension).

I expected it to be bad but I decided to give it a try since it was a recommended extension. I certainly didn't expect it to hog all my RAM and make my system unusable

I eventually got it to collect all open tabs into one but it did not allow to restore them again. Cleared all, restarted pc and the same thing. Seems it does not work that well

When restoring all, there is no way to differentiate by group

Good. But, when storing an ever increasing list of tabs, it hogs resources and bogs down FF. Disabling or exporting the list is the only solution. When you click the OneTab icon it sends ALL tabs to OneTab. No one wants that. Remove this feature immediately. WTF

why does this extension constantly duplicate itself? without fail it will show up as two of itself running in the task bar, one of them will work and one will not. It can only be fixed by uninstalling the addon. This has happened easily 6+ times, this is reoccurring and repeatable.

Why do all the links I've saved always disappear suddenly and randomly?

"Gee, I wonder what all this commotion for the UI in chrome version of this extension is about... Well, I might as well go check it out on one of my old chromium browsers..."

"Oh."

In all seriousness, I'm a tab hoarder. A rather chronic one at that, so when I discovered OneTab years ago, I never looked back. Love the extension.

I've had minor gripes in the past, namely with the UI(though this gripe is sure to be a thing of the past with the next update) and how importing and exporting is only a clipboard thing, rather than the ability to download a file, but those gripes were ultimately, just minor gripes. Nothing for me to fuss over in any real capacity, barring maybe one issue that I've only just encountered a few days ago. (Said issue seems to be fixed in the new update, so it's a moot problem.)

Frankly, the only reason I'm giving 4 stars is because I now know the new UI, which is on its way, so I'll probably up the star count when it does arrive.

Until then, this extension is near perfect, and a must have if you hoard tabs. Even with the old UI.

Hi, after enabling this extension, Firefox stops opening pages or loads them very slowly after some time. Restarting the browser temporarily fixes it. I experienced this issue on my Mac, and after Firefox Sync installed the same extension on my Windows laptop, the exact same problem started happening there as well. Please fix

The Firefox version will get 5-stars once it gets updated to version 2.x and includes some of the newer features found there.

Awesome to hear, waiting with fierce anticipation!

I install this addon in every browser of mine that I ever use. It's a shame the FF version appears to be years out of date as it's my main browser.

The Chrome version UI is very nice, and considering I use this addon daily, I'd love to have those latest features.

I truly love this add-on. OneTab has been so useful for me. Yes, yes, I admit, I leave way too many tabs open. I love being able to just close them up and send them to a clean tab list, and I think it's great that it shows the full description of each tab. The ability to export them is also a great feature.

I hope lots of people install OneTab, to be honest, because I kind of need this add-on to keep existing and thriving. I'm slightly selfishly writing this review partially because I'm kind of reliant on OneTab now, so I need it to be successful.

Seriously, though, it runs perfectly and is very smooth for me, on more than one browser, so I don't really understand the comments from some other reviews.

If the team wants to respond here on how I can even support OneTab further, please do... I'm honestly addicted to this feature now, and I can't go back to life when I didn't have it...!

I've used this app for years now and it is simple but perfect for anybody who just wants a recycle bin for their tabs.

In a single click it delete all my tabs, but in a way where I can recover any of them easily. This is the perfect solution to tab bloat. They built the perfect extension and then left it alone. Well done. :clap:

Must have, Its the best

It would be nice if the extension doesn't try to load all the tabs at once after restoring, it makes it work too slow for hundreds tabs and several windows opened. They could load only the title and be in a "frozen" mode. Like they do when you open the browser with many tabs - then only a couple of active tabs are loaded.

10/10/25 Mozilla can't handle the heat from all the incompetent add on "developers" so they are now trying to censor users by requiring and email address to login. One tab is a classic example of a Mozilla "recommended" add-on that is just no damn good.

Can't deal with long tab lists and
reduces your system to a crawl by eating up memory to produce the list. One example of many mozilla add-ons that need to be sold to someone who actually knows what they are doing. Slow to load very slow to import export which has to be done manually. Another junk Mozilla "Recommended" add-on
Now let's see if Mozilla deletes this review or my account.
Mozilla going the way of GMAIL. God help us.

Worked for bringing over a thousand tabs over from Chrome because google insists on trying to kill adblock.
My only real complaint is the layout is infinitely better on Chrome than Firefox, the Firefox layout is just a basic list broken down by window while Chromes is an actual usable program you can organize things in, it's basically the same layout as the bookmark manager in Firefox. The Firefox version is also missing over half the options page from the Chrome version.
In my opinion, it's useful as a way to move tabs over from Chrome when swapping browsers but not as an actual tool for use with Firefox, unless you're swapping to Firefox permanently don't bother with it and just get the Chrome version. Particularly since it hasn't been updated in over two years at this point and the Chrome version was just updated less than a month ago.

great addon love it the best

The extension consumes all RAM and makes PC unusable. With 100 tabs on the list (closed) and 2 open tabs it eats all 8GB and all disk swap. Giving the fact the goal of extension is to save RAM, this makes no-sense.

Have been a onetab user for years at this point, and will be for years to come! :D
