Thank you for taking the time to report this bug and helping to make Ubuntu better. Could you please try with another profile ? Maybe your profile has been corrupted.
Open Firefox from the terminal with the following command firefox -ProfileManager Create a new profile and test it from there. If it works, then you should think to reset your firefox. Help → Troubleshooting information → Reset Firefox.
