Description

I am using Arch Linux on Thinkpad T440s.
It should be powerfull enough, but webpages and scrolling all the times gets stuck for a few seconds. It's like the browser is freezing, doesn't react.
It makes working with it very slowly.

Here are more information:

Is that a 32-bit or 64-bit system?

Does this happen with a clean Tor Browser (as we ship it) as well? Like without having Adblock Plus installed and other changes reverted?

good inf on pastebin

gk & tbb-team:
This happens to me a lot, just browsing on slashdot in "Safest" security level
It will freeze, like many times when I am scrolling down. One core will peg at 100% when it is frozen, usually 10-30 seconds, sometimes longer.
Usually with 3-8 tabs open, but not predictible.

I run uBlock Origin, not Adblock Plus, but maybe is same issue? Otherwise clean tor browser.

Worked OK on tor browser 7.x, problem started with 8.x.
Problem on Ubuntu 18.04 32-bit, and also on Ubuntu 18.10 64-bit --- same.

Slashdot has a lot of blocking on uBlock Origin, sometime over 100, not sure if that is why? But it happens on other sites, too, not just slashdot.

I am using Arch Linux with LTS kernel 64 bit. But the problem was already there, when i used the non LTS kernel.

Yep, I reseted the Tor browser, but the problem remains.

Okay, just to be clear, this happened without any modifications to Tor Browser? Where do/did you get it from? And what happens with a normal Firefox 60 ESR on your machine (see: https://www.mozilla.org/en-US/firefox/organizations/all/ for bundles to test)?
