[I am changing my rating from 4 to 5 stars, since the Firefox bug has been fixed.] I "can't live without" OneTab, as it's THE daily tool I use for tab management. LOVE the simplicity & functionality! Way better than bookmarking tons of pages I'm reading/researching but may not want to keep later. BUG NOTE: Reviewers who still have problems with the bug simply need to update their Firefox browser. (Even if you don't, the work-around on old browser is very easy. We didn't LOSE our old links like some have reported, though it was very upsetting when it seemed like we did.)

This add-on is working perfectly once again. After a slight glitch, everything works as it should. One of my fave add-ons, as it reduces tab clutter instantly! Highly recommended.

Edit: Developer fixed the issue and quickly responded to my review. It was an unfortunate bug but I am happy with their fast updates and customer service.

Great add-on but the last update broke it. I need to disable and enable it to get the add-on to work

A very good addon until the last update. Now I have to disable and re-enable it each time I open firefox to get it to work.

Je trouve cette extension vraiment bien MAIS elle se désactive systématiquement à la fermeture du PC!!! bref si ça continue je chercherai une autre application. Décevant

Lost all my tabs in the last release. Tried all the fixes, turned off and on, and did a reinstall. Use the export feature to back-up my tabs, but it doesn't save the headers, or the starred order, so, more work. It seemed okay but today the whole add-on has disappeared? Very poor, have given up on this add-on. I'm using Simple Tab Groups instead, at least it works.

It's a very good tool for saving the state of your tabs and then go back to them ,when you need. Very useful for IT jugglers.

For all of you who have problems after the September 16 update, I guess the solution is disable and re-enable it. No idea why it broke after the sept 16 update but it seems to a viable solution. Otherwise, OneTab is a wonderful extension that does exactly what it says. It's one of my most used extensions. Hopefull the OneTab team could help fix this issue.

OneTab's icon keeps disappearing every time after browser restart.... I think it has started recently.... It is there, but transparent, or without an icon, then I have to go into Extensions - Disable - Enable again, then I have the icon, next time it is disappeared again...

For those who lost their data:
Just close and restart the addon.
(You don't even need to close Firefox.)

I've been using One Tab for a while, and I love it!! After the update on 16 Sept however, I opened my computer to find all the sites listed on my One Tab had disappeared, and the icon wasn't showing properly on the toolbar.
GOOD NEWS!! After I read some reviews, saying they disabled the add-on, restarted, then enabled it again, everything was restored!! Yayyyyyy!!
5 Stars!! ⭐⭐⭐⭐⭐
To all those users who had the same problem and bagged it out in a review, I suggest you try the above fix, and then change your review!! 😊

I lose everything in a moment. Installed on 3 of my 6 profiles, after restart the onetab tab show nothing and the icon button doesn't respond. I recover 2 of 3 profiles tabs with a lot of work.

Superb addon. But after update it stopped working. I disabled it, restarted Firefox, then enabled it. So everything fine again!

lost,stop working,great.

well, this add-on was great... until it just stopped working and lost all my tabs. useless piece of garbage. I would have saved those tabs elsewhere if I had known this add-in was trash 🙃

Con la última actualizacion de septiembre, se atenuó el icono y no funciona. La solucion es desactivar la extensión, cerrar el navegador y al volverlo abrir aparece todo de nuevo. Años usandola y es perfecta esta extensión.

Unfortunately became unusable due to the last update. Workarounds didn't work reliably for me and shouldn't be necessary in the first place.

Releasing an update in this state is a massive oversight.

This is a great tool. With the updates mid Sept. 2020 its toolbar icon grayed out and the saved tabs was blank. Some people uninstalled and reinstalled and said they lost the links. Instead of that I disabled it, restarted Firefox, and re-enabled, and restarted Firefox - the icon and links were all back.

Awesome, I love this addon 😍

As far as the latest update, it basically removed the add-on from Firefox. I followed what Justin said from another review, but for Mac OS : /Library/Application Support/Firefox/Profiles/08nnu9pm.default/extensions > open "Extension@one-tab.com.xpi" with the Firefox application, it'll ask you to reinstall. Now the add-on will be back, and running normal.

Lost my data due to reinstalling of the extension. Other features work well, but the main purpose is to save the data, not to lost it.
