This used to work wonderfully. Recently it started occasionally failing---clicking restore would restore only a subset of the saved tabs. This happens infrequently, but is catastrophic to workflow.

I've attempted to reach out to the developers on multiple occasions, with no success.

I would strongly advise against using this extension (even if it works 100% for you), for the following reasons:
- Lack of developer transparency. I've never successfully contacted them. It is also not open source.
- Lack of features. The one feature they have is useful for sure, but they don't support lazy loading, saving the state of multiple windows, or custom keyboard shortcuts.

I'm surprised by the extension's popularity, given that 1. it isn't complex software and they didn't get it right and 2. there's no easy way to reach the developers (is OneTab Ltd. even legit?).

I've moved onto using Tab Session Manager. It seems to have better features and is open source. We'll see how that goes.

Die Erweiterung war bisher sehr gut, für Chrome scheint sie weiterhin zu funktionieren. Mit Firefox scheint sie aber mindestens phasenweise nicht mehr zu funktionieren. Schade!

I've been comparing session manager types of add-ons, because I use a lot of tabs. With this one, it didn't *appear* to have the "lazy loading" feature, where pages aren't reopened until you click on them. Other session manager-style add-ons (tab session manager, mysessions) have this. I restored 300+ tabs with OneTab, and it used all my memory, and brought the machine to a halt. I waited for all the pages to load, and finally gave up. No one needs to use 300 tabs at once! Doing the same operation with tab session manager (for example), the 300 tabs open almost instantly, with minimal memory use.

Fantastic App
But has 1 fatal bug.
I tried to restore 12 Tabs. It only restored 2.
No error Message or anything.
The other 10 Tabs are now lost forever. Please look into that.
Would get 5 Stars otherwise

Extension desperately needs better handling of Private windows. OneTab will not on load Private windows, even if given permission to run on them.

Additionally, it can attempt to open itself in an already open private window when selecting "Display OneTab", resulting in a mostly blank but completely useless page.

Finally, left clicking the OneTab icon in the browser toolbar saves all tabs in the current window to OneTab, then closes the window without asking for confirmation. While I do not believe this to be *good* behavior in principle, it's also worth noting that the top option in the menu when *right* clicking the icon is "open OneTab", and it'd be reasonable to expect that to be the default, left click behavior.

Ideally, I'd like OneTab to understand the difference between a private tab/window and a normal tab/window, or at the very least include a "restore/open tab(s) in a private window" option. Hell, failing that, I'd accept a version that commits to the private browsing sandbox: onetab saves you tabs in a private tab/window, and closing out your private session completely wipes it.

In short: addon falls short if your, uh, heavy memory usage tabs are in private browsing windows, suffers from some minor interaction woes, and could use some options to better define its behavior (specifically that left-click on toolbar issue and auto-closing windows (would like option to keep window open with sole OneTab tab open, for example))

It works, but with caveats. I'd recommend you check out Tab Stash or Session Manager (Both also part of the recommended program) before using this one, but if you want to use this specifically then heed these warnings....


One: The extension's icon in the extension bar is a nuke that automatically saves all open tabs in an individual window into OneTab, CLOSING THEM IN THE PROCESS. If you are (rightfully) scared of activating this nuke by accident, remove the extension icon from the extension bar asap. Virtually everything can be done via context menus anyway.

2. If you share tab groups as a webpage, it will be searchable on Google until (and unless) you delete the page on the page itself. Otherwise, anyone can see it.

3. OneTab is a RAM hog that will eat up CPU and Battery like nobody's business.

I give it 2 stars because it does work fine if you keep these in mind, but Tab Stash does nearly everything OneTab does but better (thanks to it's use of native Firefox Bookmarking instead of it's own engine).

Love OneTab, using it on both Chrome and Firefox. Isn't it about time we get a nightmode? There are a couple of extensions that would provide this but non of them work now due to Mozilla cracking down security. Please please please, a night mode.

Räumt Tabs auf, ja. Aber wenn man Probleme mit zu hoher Speichernutzung hat, sollte man diese Erweiterung entfernen. Das war nämlich bei mir das Problem - quasi ein Problem gegen ein anderes eigetauscht.

從之前的 1.29 出現問題到 1.36 及現在的 1.39 ，不知道什麼時候才能結束這種不定時崩潰的日子，又沒有全部資料打包的功能，雞蛋放同一個籃子就算了，旁邊還有一隻貓ry

Desde la última actualización, funciona mal constantemente. A cada rato debo entrar a complementos para desactivar y volver a activar la extensión porque desaparece de la barra.

Randomly OneTab was not visible in the toolbar. All my links were gone! It's a great tool but not very reliable..

User experience becomes increasingly broken after each update. First it deletes all tabs (the one thing it's supposed to do), and it updates and it won't function unless you manually restart it each time you want to use it (and some people have also lost all their data)

When it's working it works, but that's the only thing I can really say, outside of those times it's an unreliable mess where you spend half your time counting down until the next time it deletes everything

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.

Hi, as other users also reported, tabs winddow and icon are gone and only reappaer after deactivation followed by reactivation of onetab. Furthermore, I suffer from the missing dark mode. Onetab is the only light window in my firefox which dazzles me. To create a dark skin would be as simple as adding an appropriate css file. On github e.g. an OneTab-Night-Mode is already available but is is not possible to modify an extension due to certificate restrictions by Mozilla. I am afraid I have to abandon the onetab extension for this reason. Nevertheless, the ideas behind this extension is still very good. Regards

This is a really important addon for me and it is a desaster: After the last update all tabs are gone. >> There has to be some sort of backup for this - can you do it please! <<

For me the last update also broke this extension. All the tabs are gone.

The developer could have at least answered to one of the complaints and tell us whether only the GUI part is broken, but the information about the stored tabs is still kept somewhere in the profile (and if yes, then how to retrieve it), or all the information is lost completely.

keeps track and saves your search history such that it's easy to look back and find what you were seeking b4. However very annoying as it opens without input from you everytime u open ur browser and then you must close it. Delays your browsing due to this.

If there are any Private Browsing tabs open, activating OneTab will add only those tabs to the list, while permanently closing and discarding all of the non-Private tabs.

I've had A LOT of tabs. I'm kind of a tab hoarder. So when I've discovered that Firefox on Android changes the tab number into infinity sign I felt a bit accomplished and also depraved of all surfing morality.
But I've also felt like I was kidnapped by that situation, so I wanted to fix it. Get it all into OneTab like I do on my desktop and sort it a bit.
The add-on only added the newest and active tab. My whole backlog is gone and you've let me down in the most crucial of moments. :(

Es wäre toll wenn die Erweiterung im privaten Modus funktionieren würde. Das tut sie nämlich leider nicht, selbst wenn es aktiviert ist.
