Collections bookmarks on the Firefox for Android homepage. I have Firefox sync. I have many regular bookmarks. Collections bookmarks from Android are obviously not available or synced with my Firefox for desktop. Are they synced or backed up at all anywhere? I cannot find them other than inside Collections. If I uninstall Firefox on my Android, Google Pixel phone and reinstall it will everything in the homepage collections be lost?

Collections are not being synced.

Yes, everything would be lost.

That's what I suspected. Cheers!.
