The text formatting toolbar in Yahoo mail has disappeared in Firefox19&20 on OS. Also hyperlinks are not working. All seems to be OK on Windows Firefox as well as in Safari!! I am running Windows7 on Parallels on the same Mac so this is really confusing. Getting tired of going to Safari for e-mail writing.
Wife has same set-up and all is well !! I have tried safe mode and have tried resetting .
I have even updated to 20 and the problem persists! HELP!!
