in about:config I had a custom useragent string set, but when I upgraded to FF4, it is no longer being used, site's see the standard FF4 user agent string

if I visit a page in FF4 and dump the contents of the $_SERVER global var in PHP, it shows the standard FF4 user agent.

It is no longer possible to add things to the user agent string in Firefox 4. The only option available is to replace it using general.useragent.override

Thank you very much, that did the trick. I just added a new config item (string) called:

general.useragent.override

and set it to the modified user agent string, and it worked perfectly. Thanks for your time.

You're welcome

You need to remember to update that preference when you update Firefox to ensure that it always shows the correct version of Firefox.
