I'm facing speed differences between Chromium and Firefox. I checked all the hints how to speed up FF, nothing helped. I also de-installed FF complete (linux Mint) and reinstalled with new settings (initially raw system only) but difference between Chromium and FF is still given, FF appr. 130 MBit/s download and 150 upload, Chromium 190 -200 down, same for up. Checked with OOKLA, same server, repeated checks over 5 days. I have a 200MBit/s FTTH connection

Start Firefox using Troubleshoot(Safe) Mode {web link}

A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?
