Webpage loading very slow randomly since Firefox 104

Since Firefox 104, some webpages can take a few minutes to load or indefinitely. Sometimes refreshing the webpage after a few minutes can help, but not always. The problem happen randomly and doesn’t seem to only affect a particular website.

I have created a new Firefox profile and the issue persists. I also use Librefox (a fork of Firefox) and it doesn’t have the same problem.

I wonder if anybody else has the same problem?

I’m using FF 104.0.2 on both TW and Leap with no issues in that regard, page load times are what I would normally expect.
