Does anybody else block fonts? Not only is it wasteful for my mobile data plan, but I just have this suspicion that sooner than later they will be used as a vector for some kind of security issue.

- adrianN 6y agoI just set browser.display.use_document_fonts to false. This sometimes leads to problems for websites that want to use symbol fonts, but I don't mind that. If I use that website frequently I might write some user script to replace the weird letters with better letters, but that's rare.
- oftenwrong 6y agoAs much as is possible, I configure browsers to display my preferred font in my preferred size.
- philliphaydon 6y agoI had a plug-in to do it but just discovered Firefox has a setting to disable custom fonts.
