Firefox address bar don't work after system update

[Lucas Panthe]

Hi, after a system update Firefox don't work anymore correctly.
If I type an url in the address bar and press enter or click on the relative command Firefox don't work and don't do anything.
If i click on a old bookmark that I've saved Firefox work normally.
After update this time for the first time Firefox have lost all password, navigation history and all data before collected.
Thanks
Luca
