Awesome, I love this addon 😍

As far as the latest update, it basically removed the add-on from Firefox. I followed what Justin said from another review, but for Mac OS : /Library/Application Support/Firefox/Profiles/08nnu9pm.default/extensions > open "Extension@one-tab.com.xpi" with the Firefox application, it'll ask you to reinstall. Now the add-on will be back, and running normal.

發生什麼災難了？在重開 fx 後，記錄下來的網址全沒了……天啊啊啊啊

資料回來了！辛苦了！改回五顆星！

UPDATE:
I am updating again to 5 stars in good faith that the developer has fixed the issue. This really is a great add-on.

Original Review:
Loved this add-on until yesterday. Everything disappeared (page with my links, icon). From reading other reviews it appears that it will work again if I uninstall/re-install add-on, but big bummer to lose my tabs. I got to rely on it a little too much. Now I will know that it is much more of a temporary holding pen.

After reboot Firefox, button OneTab becomes inactive. https://i.imgur.com/Bp7uMtM.jpg Disabling-enabling helps, but before rebooting.
P.S. Thanks for the correction!

I have been using One Tab for more than a year and it's fantabulous. I don't know how I managed without it. Thanks!

Muy buena aplicación pero debería de tener la opción de sincronzar las pestañas guardadas en los diferentes navegadores donde se utilice onetab.

This extension is invaluable to me. I was afraid that all of my tabs were gone with the last update. As others have pointed out, simply disabling and reenabling the add-on should fix the problem.

Works well. Does the job. Lost the tabs once but who knows. As for people complaining about the latest update 16/9 you just have to disable and re-enable to app to function..

The last update has a bug. I solved it by deactivating the extension and activating it

I'm freaking out. I'm a dedicated OneTab power user. [Edit: Or was. I found out that Tab Stash can import OneTab data. At least I can restore my last bu.]

And it just died. Gone. Not in my right-click menu. Won't open in the browser, but Firefox does show the manage app page. Ugh, my last backup was four weeks ago. I'm crushed. So much research gone. That'll teach me.

The latest update requires to disable and reenable the extension to have it working properly.

Update broke OneTab. Going back to previous version.

Amazing

Great Add-On. I have a couple recommendations for the developers, but they're too good to mention here.

Excellent!
