I have and briefly the majority of the time you're missing little to nothing by not using webfonts. Occasionally the design language of a physical media property is carried forward with the font in a way that is interesting enough to be worthwhile (ie _The Atlantic_'s title font is instantly recognizable but not critical).
If you're bandwidth starved (ie ISDN or worse) then it's also a nice speedup.
Yeah, but as I mentioned in other comment, I found many issues with icons by blocking remote fonts, look at Google Podcasts https://imgur.com/a/6de4uNL
Google Podcasts while ugly without that icon font is still usable but the Mercado site seemed to be inaccessible. With uBlock you could allow fonts on the broken sites but probably not worth the effort outside of really low bandwidth.
I block remote fonts w/ ublock! It's pretty handy in a "I always know text is gonna be rendered with a font I can read and it cuts down on having to make the connections to get them. ublock has a bit of a learning curve (half an hour reading on their wiki) to get the most outta it, but just blocking remote fonts just takes a couple clicks in check boxes.
Just tried for a bit, all good til I noticed in some sites using icon fonts I got a weird character, it make sense, but is a problem there, specially for icons without labels, eg: https://imgur.com/a/8D1OC9n
Don't know why devs will use fonts instead of svgs for icons, I guess there is a reason.
Someone here browse the web blocking remote fonts? How was your experience? I know uBlock Origin has this option, I may give it a try.
