Leider werde ich OneTab nun löschen, nachdem in der Vergangenheit mehrfach meine gespeicherten Tabs verloren gegangen sind.
Schade.

I don't see why it may be useful

I had 500+ tabs and did the mistake of clicking this extension. I have another extension (Panorama View) which grouped them, but OneTab discarded all of that. I tried reopening them all, but Firefox crashed, and after restarting it, all of my tabs were gone. Oh well.
TL;DR: I lost every tab I had.

stopped working after the last firefox update. The support team does not want to help much. Very upset

This app is totally useless and a waste of space. When you go to look for your tabs, half of the time they're missing anyway. Why doesn't Firefox change the settings instead and not allow sites like Ebay to open 50 million windows every time you look at a listing. The multiple windows never use to be a problem, so maybe Firefox needs to address this issue so we don't have to have useless apps like 'One Tab' taking up space on our computers just so Ebay can open another, and another, and another window that will be wasting up space in the 'One Tab' app.

Sketchy privacy policy. Use Tab Stash instead.

Absolute garbage program. Lost all my tabs after just a period of days having it installed. Found people reporting these same exact issues going back to 2017. Tried solutions and while I was able to recover almost everything, this is too risky. Can't believe it has such high ratings. Avoid at all costs.

Cannot imagine... It CLOSED all by tabs. Without asking me. I expected it helps me but it destroys everything!!! Do not recommend it. Such a behaviouur of extention is definitely not smart

The add-on somehow deleted my saved tabs after restarting Firefox.

The fact that onetab still erases and fails to save lists makes this add on effectively useless.

I used to love it, and then it stopped working, and now I lose my tabs no matter what I do. What happened to the SAVE the tabs function? Close replaced SAVE and just discards the tabs. Running Firefox 117 on MacOS Ventura 13.5.1.

Lost +52 THOUSAND tabs after a crash + update to Firefox 117. Happened a few times with Chrome (one of the reason I switched to Firefox) but I was able to recover those manually. Not here though.

This extension just works so incredibly well when it does; I will be looking for a GOOD alternative for a long time.

lost all my tabs of 6months randomly, dont use this

All saved tabs were lost from one browser start to the next. Without update or special incident. Many hours of research are now wasted. Very annoying. I can only advise against this add-on - it does not work reliably

Would not load and display icon. I have latest FF version and 10 extension icons that load into the toolbar. There is no provision to load it into the toolbar extension either. Had to disable and delete. Currently using Tab Suspender which works well in regards to memory but thought OneTab might work better but it was not to be. Good luck with it.

Worked great for about a week until now (after a Firefox update) it won't load at all. I've closed and reopened my browser several times; the OneTab icon continues to appear, pinned to the taskbar, but clicking it does nothing, and the 'send to OneTab' option no longer appears on the right-click drop-down menu. I guess I'll be uninstalling and looking for an alternative. Would be *great* if there were a OneTab back-up somewhere so I could restore my apparently now lost tabs. Bummer, since I was in the middle of a research project.

Hey! OneTab Team! Update this add-on to 1.76 like in Chrome web store!!!

What is difficult with update proccess?? Why did you abandon this extension in Firefox store and keep updating it in Chrome store?

Please update this extension ASAP!!!

I lost half of my tabs, thank you for nothing.

My god recently losing all tabs. again and again. fresh install it seems to work then next time in the browser can't find nothing and keep searching. F***! ...

安装完成后不留下确认提示自动收起所有标签页，恢复标签页时大量占用内存和移动数据流量，中途关闭Firefox导致之前收起的标签页流失，已提交投诉并卸载此扩展。
After installation it automatically fold all of my tabs (WITHOUT FUNCTION CONFIRM), tabs resuming took CPU and memory loads, and even avaliable connections bytes amount of my mobile network. After I closed Firefox, it FAILS my tabs after its automatic-folding.
I submitted report and removed this extensions.
