I didn't change or adjust anything, but when I opened Firefox this morning some websites are displaying differently. On some websites, the font size is smaller than 'normal' (see attached Wikipedia screenshots), some font styles have been changed (see attached Serebii and Archive of Our Own screenshots), and some websites are not displaying properly (see attached tumblr screenshots). I have cleared my cookies, cleared my browsing history, reset my browsing and font preferences, disabled all of my add-ons,disconnected from my VPN, logged out and back into Firefox, restarted my computer, and uninstalled and reinstalled Firefox, but the issue still persists. I'm aware I can custom adjust the font size, which solves the sizing issue, but not the display or changed font. I've included screenshots of the issues, as well as Chrome screenshots for comparison. Is there anything else I can do to fix this? Thank you for the help!!
