I love this add-on for my desktop and laptop. However, it is broken on the phone android app and deletes all your tabs! Exactly what you don't want. It should not be able to install on the phone app! I give it 5.5 stars on the desktop/laptop but ZERO stars on the android app.

Feature request:
-lockout the app installation so others don't make this mistake.
-OR, better, make it work in the android app, or make an android version if that is easier to code.
-some way to share tabs between devices. I do like the html import/export, that does work... but it would be cool if there was a sync feature like the native firefox use to do.

Update Sept.24 2020:

Last week this broke on my desktop and was not working. The icon disappeared, and then later it was visible but did nothing. The list tab was empty. Quite disconcerting.

I sent them a bug report on their one-tab.com website. They answered the next day. I was using the Sept 16 update and apparently it had a bug with something in the new firefox version. I somehow managed to get OneTab working again myself by disabling Fire Time Tracker and Hello Goodbye add-ons. And several restarts of Firefox. Then Onetab released a Sept 23 update and emailed me to let me know. It is working now and didn't lose any of the tabs from before the bug. So I'm going to say A+ for service, they responded right away and emailed me directly about the updates.
