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?

I absolutely LOVE this add on!
Big thanks for the developer to make browsing a lot better!

Notice for one tab users: Extensions works as intended on firefox quantum, any problem detected on my daily usage. BUT, because Mozilla switched to web extension, all tabs data is stored under AppData/Roaming/Profile folder and inside of \browser-extension-data\extension@one-tab.com folder, as a file named STORAGE.JS.
**If you are using SSD, or using this extension heavily on your pc, I ADVISE YOU TO BACKUP STORAGE FILE DAILY. Because of an unexpected power loss on my computer, I lost my all saved tabs data, and the worse thing is: Because of trim nature on SSD's, there is no way to recover the file itself.

As a future request, the developer should find a more reliable way to store tabs data, more than dumping all tab information into only 1 file, which is a great risk, especially for SSD users. Maybe, some regular backups or twin file system can be implemented on the extension (Take these as example, there must be more reliable ways).

Anyway, I wrote this review with the hurt of my lost data and FOR TL, DR's: I advise you to back up this extension data regularly with external tools.

Really delightful experience. To be able to work on a project basis is a game changer from a productivity point-of-view. Killing multitasking one onetab at time.
