Hi Betty, another user reported that Firefox stopped working after installing today's Windows 10 update. I don't know whether your computer is experiencing a similar problem -- normally update-related issues wouldn't appear until after a system restart. ???

Hopefully we'll learn more overnight and tomorrow about that issue.

A couple of other users identified Webroot (security software) as blocking Firefox 97 from running properly:

• https://support.mozilla.org/questions/1367248
• https://support.mozilla.org/questions/1367301

(If you are still running Firefox 96, this would not be relevant.)

If you run Webroot

People are working with Webroot to issue an update.

Until then, a user posted that another workaround would be to run Firefox 97 in backwards compatibility mode. I haven't tested this myself, but here is how you would set that up:

(1) Open the Properties dialog for your Firefox shortcut. Either:

• right-click a Desktop shortcut, then click Properties
• right-click a pinned Taskbar icon, then right-click the Firefox (or Mozilla Firefox) item, then click Properties

(2) Switch to the Compatibility tab

(3) Check the box for "Run this program in compatibility mode for"

(4) If the selector for that option is not set on Windows 8, switch it to Windows 8

As a result of this change, you may notice that some Windows 10-specific features and styling are disabled. However, I am not aware of any major changes. If you experiment with this, let us know your experience.

If you have Webroot.
