Well, I don't know how I did it, but:

I'm trying to sync my Firefox between 2 PCs. I had trouble with it, and now the situation is: a) my source PC asks me to create a new profile as it spits the dummy on my existing one; it does not offer me the option of creating a new account b) my destination PC does the same. In both cases, when I choose the "Sync and save data" menu option, then enter my email, I get the message: "This profile was previously synced to a different account. To keep your data...To sign in using <email address>, create a new profile." Creating a new profile does not have all the configuration and info that I have in my current profile.

It would be nice if I could reset everything back to square one with the sync process. Does anyone have a good suggestion?

Paul.

On IOS, for the last few days, the syncing of my profile has been failing, because of a timeout.

I have gone so far as to delete my many year-old Firefox Sync profile and rebuild it from scratch, reconnecting various machines. I have also carefully examined said profile, bookmarks, etc. I am unsure of what the timeout issue is, and whether it can be addressed, or of whether my particular use-case is no longer suitable (over the last few days) from Firefox Sync, which is one key reason I've been using Firefox more or less since inception.

Any advice, or is there a bug in the Sync back or front-end?

The relevant log lines are, I think:

4 rows of links working great and sync killed it all. Data is in the prefs.js file but firefox wont read it how can I fix this? Hours I have been chasing around with ai checking all the settings etc. wth? HOW HARD DOES THIS HAVE TO BE? please help before I uninstall and never come back. Wasted way too much time!

I installed a new hard drive into my computer and when I downloaded firefox again none of my saved links, passwords, themes, etc. moved over even though I signed into my account. Please help! Asap!

All of my passwords were deleted from Firefox on my MacBook. I am trying to get everything to sync because the passwords are there on my desktop and they are there on my phone. However when I try to sync from my phone nothing happens. When I try to sync from the macbook it is telling me to go to Firefox on my phone and sign in on my phone. The problem is that I'm already signed in on my phone so it is really difficult to follow the instructions because what it's asking me for I'm not able to do. I'm just trying to figure out how to sync the passwords and get the passwords back in the Firefox on my MacBook.
