This is a really important addon for me and it is a desaster: After the last update all tabs are gone. >> There has to be some sort of backup for this - can you do it please! <<
Hi, sorry about this. We've been working with Mozilla all morning to resolve this. Mozilla have confirmed it was due to a bug in Firefox (related to extension permissions downgrades).
To fix OneTab, just go to “about:addons” in your Firefox address bar, click the ‘cog’ icon in the top right, and click ‘Check for updates’. This will upgrade you to OneTab v1.39, which fixes the issue.
