Hi, yes know : please read this : https://support.mozilla.org/en-US/questions/1232448

IMO, the easiest solution is to replace Firefox 62 with the ESR version which is available here: https://www.mozilla.org/en-US/firefox/organizations/all/

Intended for system administrators who deploy and maintain the desktop environment in organizations such as schools, governments and businesses. But there is no prohibition on regular users using that version. The main advantage is that Firefox stays basically the same for the next 7 release cycles, and does receive security updates as they are made. Plus the Description data is in Firefox 62, at this point only the "access" fields are gone.

Install ESR 60 after removing Fx 62; your Profile won't be affected.

If you use Microsoft Office, please change your default browser to Internet Explorer temporarily before uninstalling/reinstalling Firefox. The reason for this is that the program folder may change, and then some versions of Office will not understand how to open links.
