Hello, scottedwards2000.

The Firefox Sync service limits your data storage amount to twenty-five (25) megabytes. Should you require additional space, visit the Mozilla Services Account website and Request a quota increase.

You may login from the below website using your Firefox Sync account credentials and type in a short message explaining why you should be given more storage, as more than 90% of Firefox users do not require additional data. Mozilla is therefore doing a survey and granting increased quota on a case by case manner.

Should this solution be the answer to your issue, please mark it as such. Thank you for all your interest in Mozilla and have a nice day!

Thanks, Natrist. I requested more storage, but I'm not sure that is the problem, as the sync site said I was only using 5MB.

Hello again!

I would recommend trying to reset your sync storage and wait for the quota increase. If resetting the sync service does not work, the quota increase surely will.

Let me know when you get things worked out.

Thanks - do I reset my sync storage from the primary computer?

You can reset it from any computer, using the Mozilla Sync Services website or your Firefox Sync, directly from the Firefox preferences menu.

Tried it - and resynced - still not getting all the tabs. Seems to max out at 91 tabs - maybe that is a limit?
