hi, it appears that your avast/avg security software has wrongfully deleted important parts of the browser that are necessary for proper operations.

in order to recover, please try to start firefox into safemode by pressing the shift key while it's launching. if you get it to open up normally this way then please enter about:config into the address bar (confirm the warning hint in case it shows up), and search for the preference named intl.locale.requested - right-click and reset that preference and then try to start firefox normally again.

Dear Phillipp,

Thanks for your help.

Unfortunately, the proposed intl.locale line does not appear in the list shown by config??

ok, then another thing to try - enter about:support into the address bar and hit the button to open the profile folder. then close all running firefox processes and delete the file named addonStartup.json.lz4 inside your profile folder.
