While paying bills, this latest version, 148.0 (64-bit), is not loading banks, credit cards and various other utilities websites. Something has broken. Chrome and edge load everything fine, just having trouble with firefox.

Same issue, but this has been ongoing. Unfortunately have to switch to chrome whenever I need to overcome. Case in point right now, iOS latest app, dark mode, eBay is impossible to use on Firefox. Buttons are blank. Browsing impossible. But as I say, this isn’t a new issue.

I myself have noticed this on some websites. For example, Facebook's comment box is not working properly but it is fine in Chrome. YouTube's newsfeed lags.
