I tried to fix this issue once by deleting my Firefox profile and creating a new one and it worked. This method doesn't work anymore though. I also tired refreshing Firefox, redownloading my speeddials, and using a different account but nothing worked.
After the problem returned for the second time, I noticed it happened after syncing my Firefox account. Any ideas on how to fix this? Thanks.
