Very Helpful. Series of Tabs/Screens that need to be opened daily - makes this quick & easy. I also lost all tabs - a years worth! Reached out to OneTab Support. With their suggestions & some creativity - I did not give up - took a bit of work but was able to restore ALL. I have since learned to use Export to back up my list - not ideal but better than gone. I now DISABLE OneTab BEFORE ALL FIREFOX UPDATES - so far this has resolved the loss issue [also not ideal but for me worth it] Looking thru some other reviews most of the issues I see are easily resolved. [For the record - I am not great with Tech by any definition - but can follow instruction if motivated]

Working great so far - I had 4 digit number of tabs open! The only initial problem I had was that the first run seemed to use a huge amount of RAM on Linux and Firefox got oomd'ed ;o) After that everything seems okay - I don't think I lost any tab data. I think it would be better if it asked before executing the first time.

It would be really nice to have a search feature to narrow down the OneTab list

Überaus hilfreich und nützlich, leider stürzt die Erweiterung hin und wieder ab und dann verliert man leider die bisher gespeicherten Tabs. Wenn man nicht daran denkt quasi jedes Mal bei Benutzung ein Backup zu machen, verliert man schnell gespeicherte Tabs.

I really love the addon, but I since I couldn't find a bug report, I write here:
I updated Firefox and the OneTab list is empty now. I hope, that data is still somewhere. Hope, that it's just a glitch, where it's trying to open it using the wrong path, but I cannot find the data files where all the saved urls are located. Please, help.

good extension

Love it, but needs a new and better looking icon

I love this addon, it is one of the best for Firefox. I wonder if there is no way to duplicate the onetab tab in different windows. I use two monitors and I find it essential. It could be done? =)

OneTab works great for grouping tabs & saving memory. It's the best extension for this in my opinion.

A few features that I'm missing though are:

- Sorting tab groups by drag & drop.
- Moving multiple tabs between tab groups in one go.
- Export/Import as JSON.
