Site favicons are blurry and look smaller in address bar autocomplete suggestions. Picture worth a thousand words:
I'm using the latest Firefox Developer Edition, but I've been seeing this for maybe more than half a year.
I just made a test page to see who's crazy and turns out it works fine with the old favicon which I've got saved a long time ago and it only has 16px version:
And then I tested it with the new favicon (has both 16px and 32px sizes) I got from the site just now, and it's as bad as you can see:
To see if it's a Firefox issue or the icon format issue, I resaved the new favicon using Gimp and there were multiple available combinations of options. I chose the default settings first and the results were bad:
Then I selected matching settings for both sizes and the favicon looked… bad again?
Lastly I tried enabling the compression, even though it isn't the most compatible option, but it worked fine:
Not sure what that means but perhaps some compatibility settings can be flipped around until favicons look good on all browsers.
