I get an empty pdf viewer frame. Also the debugger shows the following error;

Uncaught TypeError: Promise.withResolvers is not a function

Is there some way to overcome this problem? a future release of firefox esr?

Some web sites have begun to not work with Firefox browser on Windows 7 64 bit. Is there anyway to get a version of Firefox that that will get me back to working as well as before 4/9/2025. My Firefox web browser says it is fully updated. If Firefox browser is to no longer work with Windows 7, can you suggest a simple browser that can be downloaded for Windows 7 and tell me where and how to download it?

I have Firefox on two separate computers, a desktop running Win7Prof64bit and a laptop running Win10Pro 64bit. Both Firefox installations crash constantly, ie every 10 - 15 mins. They show the "Gah! Firefox just crashed. Please tell us what you were doing", and the box to return the data to Mozilla. With Restore This Tab at the bottom.

I always send you these reports but in about a year, the problem remains the same. Nothing has improved, I never hear back from you. Two different PCs, two different OSs, constant reports, no improvement. Why do I never hear from you? Why does this problem continue endlessly? I'm wasting my time sending you the reports. You take no notice. If you do, why does the problem continue and why do I never hear from you?

I am running Firefox in Windows 7 on a PC. When I start up Firefox, in WINDOWS Task Manager there appear between 20 and 30 instances of firefox.exe of different sizes in the Processes Window. I can End Process on most of them without shutting down Firefox or any of the other instances of firefox.exe. However if I shut down one listed with about 200,000K of Memory (Private Working Set), then Firefox shuts down and all other instances of Firefox disappear. If I open an new tab in Firefox, more instances of firefox.exe appear.

I have never seen this behavior before. I tried uninstalling and reinstalling Firefox, but the same behavior occurred. Is this normal behavior, or should I be concerned?

I have enclosed screen shots from the Task Manager. I also have a Dump File of a couple of the firefox.exe instances, including the large one, if that would be helpful.

Thank you.

I can't install extensions anymore, when clicking on "install" button, the waiting icon keeps moving forever. I'm using firefox 115.20.0 esr 64 bit. Also tried in troubleshooting mode, no change. I've tried several verified extensions, and many that used to work fine precedently.

I accepted an update to my computer and immediately Firefox could not load, the exe file is missing. Again I use windows 7 . May have lost all passwords and bookmarks. Please advise.

Yesterday I was on the Newsmax website. Today Firefox says its not a secure connection and it won't let me go to Newmax.com. I then tried to use the google browser and it went right to Newmax.com no problem. I am using Windows 7 like I have been for years. Please help. Thanks, Al
