The Pale Moon 25.0 update released earlier this month was a major one as it cut another tie with Firefox. Up until this point, Pale Moon used a Firefox compatibility setting to display a Firefox version in its UserAgent string.
The UserAgent is automatically submitted whenever the browser connects to a server on the Internet. It reveals information about the operating system and web browser used to connect to the site.
While many Internet sites don't process the information, some parse the UserAgent. There are sites out there that won't work if you don't use a supported UserAgent while others may deliver different contents to you based on the information.
