I know that I can disable the downloading of external JS files on the Firefox browser (using either about:config
or certain add-ons (e.g. QuickJava)).
Is there some way to block the downloading of external CSS files in a similar manner?
Please Note: What I need is NOT to disable CSS from getting applied to web pages, but to prevent external CSS files from getting downloaded altogether when visiting a web page.
I already have the QuickJava add-on installed. Although it has a "CSS blocker" option, I have observed that external CSS files still get downloaded while the option is turned on. (On the contrary, when QuickJava's JS blocker is enabled, external JS files do not get downloaded.)
