Firefox is much slower after the upgrade, and htop tells me that Firefox mostly uses only one CPU core, instead of distributing the load. Most importantly, Facebook is next to unusable after the upgrade to 18.04.

Steps I've already taken:

  • Enabling hardware acceleration in about:config
  • Using uBlock Origin to mitigate requests and traffic from third-party sites (as I did before)
  • Installed intel-microcode
  • Installed the Nvidia GPU drivers through Settings Manager

Incidentally, Core 4 seems to carry most of the Firefox load. I've never seen it jump to another core.

  • WTF. Now Firefox is blinding fast again. As a stopgap measure, I installed {chromium-webbrowser}, and so Firefox knew the end was nigh. In a last glimpse of fury, Firefox reared its head and was fast again. I don't understand computers.

  • ...now, it's there again. Now I understand computers even less.

I've installed the 4.16.13 kernel from kernel.ubuntu.com/~kernel-ppa/mainline and it seems to work now...

...it was so frustrating.

Edit: No, this didn't really solve the problem either, after longer observations.

What I did now was:

sudo apt purge linux*

Attention, this step alone will make the computer un-bootable! Don't forget the next line:

sudo apt install linux-headers-generic linux-image-generic linux-tools-generic

Now, Firefox works much more fluent, and Firefox loads are evenly distributed over all CPU cores.

I will observe... again.

  • Looks like it works for me, too. Also observing this for a while. Any idea why this might work?

I turned off Bluetooth found below Wi-fi settings. That fixed it for me. Os-Ubuntu 18.04 LTS.
