Is there a way to change the user agent posted in http headers in Firefox 50+
Hello all, For reasons of privacy, I want to be able to change the OS identifier in the user-agent string that is sent with every http request. I remember with older versions of firefox this could be accomplished in about:config and changing the useragent string, but this doesn't seem to be an option with newer versions. I have tried on both firefox for FreeBSD and Windows 8.1, to no avail.
If it is assigned at build time, could you please direct me to the area of code where this is handled so I can fork the code, change it locally, and build it for personal use?
This is the string I am trying to change: Mozilla/5.0 (X11; FreeBSD amd64; rv:53.0) Gecko/20100101 Firefox/53.0
I suspect it may be stored in one of the files in the ~/.mozilla directory, and while I wait for a response, I will be picking through there.
Thanks in advance,
Also forgot to mention: I tried adding the "user agent switcher addon". Add on did not seem to work in firefox 53 on FreeBSD. Will try windows next time I have a windows machine.
Just to cherrypick from those documents:
general.useragent.override is the string that needs to be added and set
Glad to help. Safe Surfing.
