> Because a lot of people don't have the technical ability. The tab is called "Advanced" for a reason. Come now, it doesn’t take any technical ability to use the checkbox. It’s called “Advanced” because it’s more complex tweaks that most people aren’t interested in and which take a moderate amount of space so they want to keep it out of the way lest the page get too long, not because it’s hard to use in any way. > It quickly gets more complicated for some sites, which users might use often. It is rare for this to have any ill effect on any site (icon fonts that don’t use the PUA and aren’t Material Icons (for which Firefox has manual exceptions in place) are about the only case, and they’re distinctly rare nowadays—I only recall encountering about two cases last year, both of which were paired with labels and thus unimportant), and in those rare cases it’s unusual for it to be a real problem (they’ll almost always have labels or tooltips). I will quite happily recommend changing this setting to completely untechnical users. It occasionally causes very mild harm, and can theoretically cause great harm for particular sites (but I haven’t found such a site for years, and any such sites were surely already broken anyway), but the rest of the time it improves matters markedly.
