my firefox has changed- I have lost my tool bar and now asking me to sign in.Have I been hacked
my firefox home screen has changed on my firefox homepage. I clicked on a security add on and now I no longer have my same home page. I tried to get a Mozilla home page and my computer typed unknown characters- like for another language. I have a MAC using 10.13.6.

Hi, it is possible or there is corruption in a file. How about 1st run a scan : https://www.malwarebytes.com/mac/
After if still issues : SAFE MODE
In Firefox Safe mode these changes are effective:
- all extensions are disabled (about:addons)
- default theme is used (no persona)
- userChrome.css and userContent.css are ignored (chrome folder)
- default toolbar layout is used (file: localstore-safe.rdf)
- hardware acceleration is disabled (Options > Advanced > General)
- plugins are not affected
- preferences are not affected
TEST''''is issue still there ?
If still issues : REFRESH INSTRUCTIONS please try a Refresh but Note that this does more than uninstalling and re-installing does. Normal uninstalling does not remove some preferences which may have become corrupt. Please Refresh but do this 1st: Delete your Cookies and Cache and TEST.
TEST....... If no issues then Extensions which need to be added back in 1 at a time and tested ..... Or it is your Profile : Make a new one and test ...:
If is your Profile :
Note: Any customization will revert back to default, you will also need to reinstall Extensions.
