''[Locked as a duplicate of https://support.mozilla.org/en-US/questions/1279980. Please follow up there, thanks.]'' I wanted to use my webmail but noticed that my fonts over the entire page have changed. I tried to fix it with these tips and tried to zoom in/out but it didn't fix it. When I enabled the box that pages can use their own fonts than it was normal but then another page was wrong. It just moved the problem. I have no clue what I can do else? this is what I've tried without succes https://support.mozilla.org/nl/kb/lettertypen-en-kleuren-die-websites-gebruiken-wijzigen?as=u&utm_source=inproduct In Safari I have no issues just in Firefox. I tried to clean the cookies, restart Safari, restart computer, re-installed Firefox but still could not fix it. I'm desperate... Regards Els
