I've been using Firefox for maybe 20 years but the upgrade to 145 has completely floored me. I run Windows 11 and up to now I've had no problems with Firefox on it. Alas, since the 145 upgrade I've found that any site that involves static or video imagery that it simply won't load the graphics. It just indicates it is trying to load it indefinitely. If it ever completes, it does so with multiple errors. Experience suggests that it is primarily but not exclusively a graphics problem. Some text sites won't load either. I've tried troubleshooting, refreshing and even doing a fresh install with a new profile but none of this makes any difference. As a result, after those 20 years I've had to give up on Firefox altogether. I've no faith that there will ever be a fix that allows me to go back to Firefox. This is sad because I'm used to Firefox and the user UI suits my preferences and experience. Alas, no more. It has simply become unusable for me.
