Many websites that I use regularly, such as Zillow, no longer work correctly in Firefox ESR (115.33.0). The top menu in Zillow disappeared this week. Others work, but all the text is greyed-out. All except the text thing seem related to Javascript features. For instance, check boxes on a Wordpress site that I manage quit working last month. Some, like www.RCgroups.com just sit and spin, and never fully open up. But they all work fine on an old copy of Chrome (109.0.5414.120), that is no longer supported on Windows 7 and hasn't been updated in probably 3 years. My only plugin is NoScript, but the problem is the same whether it's turned off or not. And I also use NoScript on Chrome. I use Win7 for the same reason I use Firefox -- it is safer, far more stable, faster, and it doesn't force updates on me that invariably break things. I appreciate that Mozilla has extended support for the last stable version of Windows. But somebody should look into this growing compatibility issue.
