I just moved to a new phone and I just want all tabs bookmarked. Opening all of them on desktop won’t work because that option usually only loads the first hundred or so before locking up.
Hey! I do this too. It’s a not so great habit but the Treestyle tabs firefox extension does exactly what you need. You can select all tabs and click bookmark tabs. I actually recommend another similar extension called Sidebery*. It can even create occasional snapshots so in the case of a browser or system crash you have backups on disk or memory.
EDIT: Oops, meant to say Sidebery not Tabby. Sorry, wrote that just before bed. Tabby is a great terminal emulator though!
I looked up Tree Style Tab, Tabby and Tab Stash another poster recommended but none of them are compatible with Firefox Mobile so this won’t work unless I can force compatibility.
