Description 1gooddood1 2018-10-31 20:48:06 UTC

Description of problem:
In the Fedora build of Icecat the user-agent includes "Fedora", instead of showing only the generic "Linux", while using rivacy.resistfingerprinting=true, the default in Icecat. This adds large amounts of entropy to the fingerprint, and prohibits blending in with the other RFP users.
The binary provided on the GNU site does show the generic UA, so I imagine it has to do with the build process for Fedora. I quickly checked regular Firefox from the Fedora repos however and it seems shows the generic UA just fine while using RFP.

Steps to Reproduce:
1.
Start new Icecat profile.
2.
Check the useragent.
3.
Observe

Actual results:
 Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:60.0) Gecko/20100101 Firefox/60.0 

Expected results:
 Mozilla/5.0 (X11; Linux x86_64; rv:60.0) Gecko/20100101 Firefox/60.0
