Add-ons can´t be install, becouse Firfox is needed to install the Add-ons
Hello, my problem is:
Firefox 79: I have select some add-ons for to install. But in the discription from the Add-on ist written "Firefox Only- Download Firefox Now "
Sorry, I´m working with firefox and my standard browser is Firefox. Add-ons which are migrated from firefox 78.x to firefox 79.0 are working.
Have somebody an idee to change my problem?
Many Thanks

Did make sure to reset general.useragent prefs on the about:config page ?
You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.

Your anonymization tool Abelssoft must be interferring with addons.mozilla.org.
