An option to disable all styles ONLY on the current site or URL

[Nicolai-Nielsen]

Desperately need an option to disable on all styles on a single site or page instead of turning all the styles off for every site.

For those who has a lot of " global styles

(URL colours, text highlighting, dark pages, visibility of objects, ... skip the following if what I am saying is clear:
(on YouTube I have all chat's box visibility set to "none", and use a style that expands the video to the page's width, and disabling and enabling all the styles forces me to refresh the tab!) ) ",

then an option like this lets you keep testing stuff out without having to effect the styles of other pages!

Thanks for reading :)
