Tor Browser is not loading the homepage properly, after the 1st load.

Hey all,

THIS IS A TOR BROWSER ONLY ISSUE!

Here's the video showing the issue:

TOR BROWSER is not loading the homepage properly, (when i save the divi wordpress theme) after the 1st load.
- If i save "Fullwidth Code Settings" empty, the header loads fine every-time, (but on the 2nd time and after) the CSS and black background on the last section do not.

- If i save "Fullwidth Code Settings" with the .js particles code, (the 2nd time i refresh it), it fails to load the header image and transparent background; and also does not load all the CSS properly, including the black background on the last section.

I believe to have have removed CSS from everywhere, and it still happens! DON'T THINK IT'S CSS RELATED!

I've been testing this extensively the last days.
Whether the issue is coming from either the full-width header section or the "Fullwidth Code Settings" module alone, (or both), i don't know!...

I need to find the root cause, and your feedback will help me get there.
I've opened the Tor error console, but the errors thrown do not help me get anywhere.
Any of you with interaction with Tor browser know what step/steps can i do in Tor, to get to the root cause?

I'm going to chat with Tor support too.

 

Having the "Critical CSS" option to off solves the issue!
What could this mean?
And, what are the inconveniences to have this option off?
