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

lost all saved tabs after a browser update

Great extension

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.

For us who have gazillion tabs opened this is a great way to organize, group and eventually restore tabs.

Much better than storing links in bookmarks.

One could say improvements can be made but as long as it works like it does now I'm happy.

Don't change it much, It's lightweight, fast and it works.

When it works, I love it, but it often disappears and I can't find it again.

ENG / HUN: Be very careful with this: it archives everything in one click and without warning (!) - which means that if you use it a lot (for which Firefox is about the best browser), it simply takes an extremely long time to save!!! The reset takes approx. it's impossible because it starts filling up the tabs - with a huge memory requirement! I didn't have time to wait (any process), but luckily I saved everything before that with FoxyTab. That's what I recommend! I recommend that you 1. ask about it 2. write down the number of ears 3. give some calculation so that approx. how long does the process take 4. do not fill the tabs!!!
HUN: Nagyon óvatosan ezzel: egy kattintás és figyelmeztetés nélkül (!) mindent fület archivál - amitől ha sokat használsz (amiben ugye kb. a legjobb böngésző a Firefox) egyszerűen extrém sok ideig tart a mentés!!! A visszaállítás kb. lehetetlen mert elkezdi a füleket visszatölteni - óriási memóriaigénnyel! Nekem nem volt időm kivárni (semelyik folyamatot), de szerencsére mindent mentettem előtte a FoxyTab-al. Így inkább az ajánlom! Javaslom hogy 1. kérdezzen rá 2. írja ki a fülek számát 3. valami kalkulációt adjon hogy kb. mennyi ideig tart a folyamat 4. ne töltse be a füleket!!!

Have been using OneTab for years. Great extension, would love to rate it more highly, unfortunately there's too many usability issues. 1) I've just imported saved urls and because no feedback is given, I ended up importing the same URLs several times, and losing the latest open pages. No way to undo that, the "reject duplicates" is not active by default, and does not work retroactively.
2) I've submitted a request a long time ago, to select a group of tabs easily, and restore them all - not necessarily the whole group. Bulk delete should also be an option. Unfortunately, available options are very limited, and the extension has remained unchanged for a long time. Still grateful to the dev for creating something that should be native to any browser, but it really needs more work for me to give it more than 3 stars.

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.

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.
