Description Max 2018-08-22 15:26:40 UTC 
Using multiple instances of browser:
First opened profile setting overwrites all settings of instances afterwards.

Reproducing:
1.Create 2 profiles, 1 with javascript and one without.
2.load instance and profile without javascript (and keep it open)
3.load isntance and profile with javascript

Run 
https://panopticlick.eff.org
Result
Either via looking up the settings graphically or
via test result, the setting is overwritten from the second profile.

Conclusion
This is misleading or potentially dangerous to allow, since it adds unnessessary attack surface and more importantly makes it unaware to the user. Disabling multiple instances or fixing why the profiles are not loaded accordingly would be solutions.
Comment 1 David Rosca 2018-12-24 19:20:07 UTC 
If you start new instance with separate profile "falkon --profile profile_name --no-remote" then it will create new process, so it will not share anything.

Please provide exact steps to reproduce your issue.
