Help restoring >10 tabs on Android with Firefox Sync after pressing "Close all tabs"

x3gamma

Hi, looking to ask if anyone has experience with restoring Firefox open tabs after closing them accidentally on Android.

Environment: Android 14 Firefox account sync enabled

Things tried: 1. Firefox Sync (The open tab information was promptly cleared away by the sync) 2. Open tab information from a separate desktop Firefox browser with Sync enabled prior (same issue as #1) 3. ADB file access (no permissions) 4. ADB downgrade install to pull old files (failed due to Android 14) 5. Accessing "files:///data/data/org.mozilla.firefox/..." (cannot download files and looking at the timestamps, the SQLite files have probably been overwritten) 6. Firefox debugging (Nothing useful) 7. Searching for a way to get Firefox Sync historical data (doesn't seem available) 8. Mailing customer support (No response)

Things I didn't do prior to this incident (answering the common responses found online): 1. Bookmark my tabs 2. Firefox Collections

On a side note, I can't understand why a button like "Close all tabs" does not have a confirmation dialog. Considering that there is no quick undo button and "Recently closed tabs" can only show up to 10 tabs on mobile, this function is extremely destructive and it is a miracle that with so many incidents (from online sources), that a safeguard or Undo function has not been implemented.

Hi

I am sorry but there is no way I am aware of to safely recover those tabs.

That's such a pity. Thanks for the response @Paul.
