If it doesn't happen in Safe Mode, it sounds like an add-on issue. If you're running Windows Pro version, try this. How to Use Windows 10's New Sandbox (to Safely Test Apps) Tell us all about the computer. What security software are you running? Does it happen under a different user account?

Windows 11 Home Edition Version 10.0.22621

Norton Security Ultra

The Norton extensions were all disabled when the crashes continued in normal browser mode. The only other extension listed (also disabled at the time) is Amazon Assistant.

I don't have any other user accounts. The problem occurred when signed in and not signed in to a Mozilla account.

Just create another windows user account or use the Administrator account just to see if Firefox goes boom. Can you disable Norton, reboot and try again.

Try upgrading your graphics drivers from the manufacturer's site. You might need to disable hardware acceleration.

I tried those suggested solutions and the problem persists. I also refreshed Firefox as instructed and the browser continues to crash as before. I don't know what the solution is at this point except to ditch the browser I've enjoyed for many years. This is a ridiculous thing to have happen following a simple update.

You said Troubleshoot Mode works so it should work if you disable hardware acceleration.

Can we get more info about your computer before you throw in the towel? Laptop, Desktop, DIY? Make and model?

Desktop.

This could be about a Full-browser crash on visiting site with a particular kind of bad webfont.

• GraphicsCriticalError: [G0][GFX1-]: Failed sanitizing font 2 (t=2.8803)

Can you try a different default font ?

Make also sure you allow pages to choose their own fonts.

Here are other crash reports from some previous instances. This has happened when I open Yahoo mail, log into my bank account, (ironically) scroll down to read the crash reports, etc.

Did you already check for current drivers? https://www.acer.com/us-en/support/drivers-and-manuals Also try another version of Firefox and make sure to install in a different directory. https://www.mozilla.org/en-US/firefox/channel/desktop/

Does it still happen if you go to about:config in the address bar and change layers.acceleration.disabled to true then restart the browser?
