Still want a solution for me to use my previous existing SYNC account (from my XP comp., for which I have the security key) on my new WIN 8.1 computer.

My old XP computer died. When I loaded FireFux on my new WIN 8.1 computer, "I never got the option to enter my old security key to activate my existing SYNC account on my new computer."

At this point I am so disillusioned with FireFux' SYNC feature that I won't even try to activate it on my new computer. "SYNC is nothing more than a crutch made of Papier Mache; after you are using it for a while getting around pretty well, it will suddenly become non-functional and be found to be beyond repair."

hello dfun47, firefox 29 and upwards is using a different sync login system which isn't compatible with accounts set-up in older versions.

in your case you'd probably have to use a workaround and download the prior firefox 28, disable automatic updating for the moment (in options > advanced > update), link it to the old sync account and upgrade after you have successfully restored your data this way...

THanks for your prompt and concise answer. Since i am used to working around to get things done, i can give it a try. after I do this ho do i go about deleting tabs from old computers, which show up in my list of "TABS FROM OTHER DEVICES", on other devices (I NOW have about five old devices)?

or,alternatively,is this all more work than it is worth? --as i noticed tha FIREFOxh as already started syncing up my devicest hat areusingth esame gmAILacco unt?

when you update to the new sync successfully after completing the steps from above, any obsolete "tabs from other devices" should be left out from the migration anyway.

if you have an issue with flash, please open a new thread about that...
