Is it actually impossible to use firefox sync to sync ALL *TABS* between different *desktop* versions, and if so...

Ok, so please someone tell me I can open a large fraction of my around a hundred tabs instead of opening each one individually with the extremely marginal FF sync?

The new version broke too many of my extensions in a way that made it super unstable and unusable?

Really frustrating because the first round I installed portable 79 on top of the 80 in the directory, and it loaded and ran fine (Edit: I may be mistaken here, but it seemed that way). I close it to relocate the directory, and now even if I make a while new thing it whines about profile corruption, which I dont care much about with zipped FF portables, and refuses to reopen with all your tabs and extensions configured like it would before. Im about to move to a clean computer to hack it again because they have just done their level best to make it impossible to fix my browser, and I might have to try Edge, Opera, Vivaldi, Brave, or something else. Mozilla, just why bro?

And MAN, I am SO looking forward to configuring settings in like 20 extensions all over again YAY! This is just like the worst possible timing for me, RN. Oh yeah, al my greasemonkey scripts.
