Description

Upon loading the website with uBlock Origin enabled, the page only shows white, even though the HTML document shows that there are indeed elements present.

Loading the website without uBlock enabled results in the proper page being shown. Re-enabling uBlock and reloading the website in the same tab results in a properly rendered page, with slight differences in the filter list (most notably the myfonts.net domain). This cannot be reproduced in a new tab without disabling uBlock first.

Test again in a new Firefox profile with only uBO and its default settings.

Test again in a new Firefox profile with only uBO and its default settings.

Just did, same behavior as previously detailed.

[stephenhawk8054]

In the new profile, can you open new tab > reproduce the issue and on that page > click on uBO icon > 💬 Report button > scroll to the bottom > click on Troubleshooting Information and copy paste it here?

Then can you go to about:addons page (type in URL bar) and screenshot it here?

@hackerTiger21 Which country are you when accessing the site?

United States

[stephenhawk8054]

I can't reproduce the issue. The page appears normal for me

[hackerTiger21]

This is what I'm getting on initial load.

[stephenhawk8054]

I still can't reproduce it so I can't investigate more.

[hackerTiger21]

There were a lot of console errors both with and without uBlock enabled, it's possible that it's an issue that has to be fixed with the site itself.
