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.

Good extension!

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.

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.

This has Saved My Sanity! (& several searches).
No more having half a dozen or more, windows open; with dozens of tabs open in each.
OneTab, on one window, no more confusion or getting lost in the mess.

Wouldn't be without OneTab. Saved my butt many times over! Nothing lost on a crash when they are also in One Tab!!
