I've setup Firefox sync app on my laptop and have now also installed it on my PC at work. when I setup on the work PC I proceed through: I'm already using Sync on another computer - I then proceed to: Enter Account Information - when I complete this I get the answer: Incorrect username or password. I have checked Username and Password on my profile and I'm using the correct login information - but I can't access. Can you help me with this problem?

We are many who hope that Mozilla Firefox will buy Xmarks an application that worked flawlessly across all browsers...siiiiigh!

Kind regards Ole

Do you have a user name with only lower case letters?

I've seen it mention that that can cause this issue.
If you have the try a user name that starts with a capital.

Also have this problem.

Synced on home machine and synch has happened as checked time stamp.

No 'username' in synch profile but current account is the full gmail address I used.

I type that into Firefox Home on iphone as username.

Had password with capital letter but changed it as capitals not in list of allowed characters.

Still get message - username not found.

This appears to have been a bug which has now been fixed.

I just downloaded an update to the Firefox Home app on my iPhone and repeated all my previous steps - username is full email address - and it now works !

I had to Reinstall Windows XP, Firefox, and Now Synch does NOT have a Sign in Button in Tools Menu! Synch is not downloading my Previous Bookmarks, Passwords, etc. HOW can I fix this?
