1749922 - Sudden CPU spike causes loss of internet connection until FF process is killed

Status: VERIFIED DUPLICATE of bug 1749910

(Core :: Networking, defect)

Description

[striborgvidya]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:95.0) Gecko/20100101 Firefox/95.0

Steps to reproduce:

Usualy Firefox use, no new add-ons were added nor updates were installed.

Actual results:

Firefox started experiencing a sudden CPU spike (80% or so).
Following it, all kinds of internet use became impossible. Videos no longer loading, new tabs not loading, yet no error ever displaying.
CPU use stayed constant no matter how long it was left alone (30 mins or so) until the process was killed.
Task manager shows no network use, making the likelihood of it being some sort of update unlikely.

Rebooting or killing the process only solves the issue for 10 minutes or so, until it presents itself in exactly the same fashion.
