Firefox Support Forum

I have Firefox on an old MacBook which hasn't had its macOS updated for a couple of years, and a new Mac running up-to-date Monterey. In both, Firefox has just developed the same problems at the same time: pages won't load, and the program won't shut down normally -- I have to use force quit. Safari works fine and I've tried all the usual solutions, bar deleting and reloading the app. I don't want to do that yet since the problem is the same on two different computers and an old and a new macOS. Since Firefox has recently updated, has that caused the problem?

edited iOS to macOS as iOS is a mobile OS for iPhones and moved thread to (desktop) Firefox section.

Dear Community, I love Firefox but here is how fonts now look like on my old MacBook Pro (v10.13.6). Why is this? How can I fix this? My Firefox version is up-to-date. As shown on the screenshots below, on Chrome fonts appear to be normal. Thanks so much for your guidance!

Hi, I recently installed Firefox 49.0.2 on my mac which is up to date on OS Monterey. When I opened Firefox the browser screen was completely blank. I can see the URL bar and when I move my mouse I can see that there are links on the page which I can click on, but the screen is blank.

I've tried redownloading Firefox as well as other, older versions and they also show a blank screen. Only the browser screen is blank; if I click on add-ons a new tab opens and I can see that.

The link below has three screenshots showing exactly what I can see. Hopefully this makes sense. Thanks
