Finally OneTab revive! However, it may lost multi-account container information when restoring tabs.
Overall, it's awesome!

Saves Related Tabs into Manageable Groups that Can Be Named, Locked, Starred & Exported/Imported. It Works.

Great application! Excellent in helping with web searches and especially how to organize bookmarks.

Works like the tab saver in microsoft edge but much better. Keep up the great work.

節省很多記憶體

Love this extension. I use it to keep my usual tabs all in one place but without having to suck up memory while using only 1 or 2 or 5 of the many. It collapses all tabs into one page of links so they don't all have to stay open when not using them but keeping them handy. Even after reboots and crashes (which firefox seems to do a LOT since the quantum update).

This is my most used add-on, it hasn't caused me any problems and I rely on it heavily. Adding a sync feature that worked with the firefox account would be incredibly useful.

Fantastic for keeping track of open tabs.

It's nice & neat! It will be better if support drag & drop groups around to re-order them.

its happens again!!!!. on firefox onetab lost all my data. So onetab and firefox dont care about us users.

超棒，瀏覽網頁、整理資料更有效率！！

Very good and useful addition!

good addons

easy covient

i wish if you add send right(left) tabs to one tab and send all tabs to one tab except this tab.

I love that concept and it really works, however. I noticed a slow down and inadvertently crashed Firefox. When that happened I lost a number of tabs only saved in onetab and can't figure out how to recover them.

This program is SO useful. I "gather" many, many web pages, and the tabs clutter my browser, blowing up my memory use.

HIGHLY RECOMMENDED!!

Really useful add-on in a number of ways.
Obviously clears the tab clutter but I find the 'one-click restore' feature a quick way to open repetitively visited sites.
Only issue I'm having recently with FF v57+ is not being able to pin the tab between restarts - plugin issue or FF?
