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.

Most useful Firefox extension I've used. Especially good for saving RAM on older machines. Very helpful to save URLs of sites you're actually interested in (not just wading through history lists).

I've been using One Tab in my Firefox browser for a month now. It's been so useful and easy to use that I installed it as an add-on/extension in my Edge and Chrome browsers too! When I left feedback, they responded right away and resolved my issues. Now, I'm going to write them re some feature requests/suggestions.

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.

Good extension!

Great concept but poor implementation. Always crashing, losing tabs, slows browser or becomes overwhelmed by the volume of tabs for stashing. There are other add-ons available that do the same thing, swiftly and reliably.

Easily my most used extension that isn't an ad blocker. Firefox is already a memory heavy browser especially when you have a lot of extensions that you can't justify removing; this extension helps me keep my bookmarks clean and my memory usage to a minimum. I keep it pinned to my tab bar for ease of access on both my desktop and laptop. I especially love how simple it is to sync both my laptop and desktop OneTab pages.

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.

It makes it so much easier to organize groups of tabs by any topic or no topic. 'When I get time, I will move bookmarked tabs into One Tab.
