[Solved] Can not install Firefox Avast Password extension

[REDACTED]

My Firefox keeps telling me "Avast Password could not be verifed for use in Firefox and has been disabled"

I want to remove this extension to reinstall it from Avast Password Settings section but there is no "Remove" button.
I try to find the extension's files in AppData > Roaming > Mozilla .... but nothing related
Even I uninstall and reinstall Firefox, it is no use/

I like Avast Password, how can I solve this problem ?

Thank you

+ type about:config into the URL bar in Firefox
+ in the Search box type xpinstall.signatures.required
+ double-click the preference, or right-click and selected "Toggle", to set it to false.
+ go to addon then enable Avast Password extension.
