The option stop opening up in a new tab is missing
This is the simples option, not always help but we encourage to try.
- Copy and paste in address bar about:support - Select following http://nimb.ws/Vm5pjy - Rename this folder to any name and restart Firefox http://nimb.ws/awxfuW BUT don't delete it. Just rename.
If it won't help, let us know.
Also, if you don't see welcome message but settings get rest, that will be fixed next update soon.
