on a scale from rust to webdev, how annoying is it to program firefox extensions? if one wanted to, say, put back the cute illustrations on error pages?
@elilla i think these error pages are "privileged" so regular extensions cant really modify them
so, userchrome.css may be the only possibility here
@elilla firefox extensions are JS, but not particularly annoying. I don't think you can inject into the error pages tho.
@elilla you _might_ be able to achieve this solely with userChrome.css
i'll have to investigate
