Many thanks for your help.

I haven't experienced this problem before. It occurred after an automatic update.

The useragent being this way is not due to any recent Firefox updates but was stuck that way due to being modified by a Zemana software.

Some websites have been cracking down on older web browser lately and will either block or give alternate or more limited access to those older versions of web browsers. For example they may be making sure people have a web browser that can support TLS 1.2 (Firefox has by default since 27.0).
