Firefox Support Forum

On my iMac 2017, up-to-date OS, Firefox won't load YouTube. It only shows the spaces for videos. Attached is a screen shot with the console info, but I don't know what it's telling me. However, on my MacBook YouTube works fine, so maybe I have a setting wrong on the iMac? Meanwhile, I just switch to Safari. Thanks for any help

So this problem keeps happening to me - I click "upload" on a website and nothing happens. For example, trying to upload photos to my website or upload files to a platform. Frustrating. To work around it I've been using a separate tab of Google chrome but it's such a pain to keep swapping back and forth. Please help!!

My Firefox browser is somehow corrupted with foreign language features. See in the picture that much of the text is in English - the selected and preferred language. It is what the Settings are set to. But notice that bits and pieces are in some other language. I recently made a trip to Spain and used translation features while there - but those was all reset to English. I've gone into Troubleshooting mode; I've restarted; I've reset and restarted. But I can't seem to get rid of the gibberish. WTH!!!! All copies of Firefox, on all owned Mac machines (i-Phone; Mac Mini; I-Mac Pro; I pads) are set to English. About the only thing I haven't done it uninstall and reinstall Firefox. Thanks for any help you can offer.
