I was finally annoyed enough that the various icons on for the site's I've visited are sometimes nice and big, looking high quality. And other times they're oddly small. Even on popular big sites. Many like Slashdot, Gmail, and my local Netgear router have a smaller icon. Others like Audible, Reddit, and ArsTechnica are bigger.
I did a search and find a ton of posts about the same issue. Generally with nothing useful or telling the user to manually modify the user CSS info. Like this post from a year ago https://support.mozilla.org/gl/questions/1356680 There was another from 2 years ago, and many I didn't open.
I tried to search for how site creators should create this image correctly, but never found anything. I don't even know what to call it. Is this the "favicon"? That is used when bookmarking a site (right?). Or a different standard name and location?
Either way, Firefox needs to explain what would fix this...or it should adapt itself like the above post recommends (which seems to zoom a bit more in general, and zoom more at maximum).
I'll also mention that the new tab page being terrible was one of the final straws that made me start looking for a replacement (after switching away from Chrome when they prevented ad blockers with the new extension format). I even installed an extension to enhance the "new tab" page, but it didn't change anything at the time (uninstalled again).
