bug#58011: Jitsi, Bowser, and IceCat's user agent string

[Yusuf Talha]

Hello, I am the one who reported the issue to Mr. McMahon.  I didn't
write here because I thought it isn't a GNU IceCat issue, rather it is
FSF's Jitsi instance issue.  Sorry about the inconvenience.

In the beginning, I thought it is related to the browser's user-agent
string. Because I installed `User-Agent Switcher and Manager' add-on and
then I could access the `jitsi.member.fsf.org' website.  After that, I
noticed that useragent string doesn't include "IceCat" as you said.  I
started to spoof Navigator API with CanvasBlocker add-on, which helped
me to bypass the issue.  I didn't want to mess with IceCat's defaults in
the first place but disabling privacy.resistFingerprinting seems to work
with Jitsi.  Ironically, it seems like enabling fingerprinting makes my
browser more recognizable, if I understood correctly.

Thank you for maintaining this browser both for installation scripts and
Guix package definition.

Also, this is the first time I'm writing to a mailing list with Gnus, so
please let me know if I didn't follow some conventions.
