I recently had a CAC type card company install a security module in my device manager that will not load or unload. Since then my browser sessions will not close properly. Upon close I get notification that firefox is still running and needs to be closed or that it did not close properly and I need to close it through the pop up notification. I have uninstalled/reinstalled but continue to get the same issues. I don't have this issue on other machines for which I sign in to the same firefox account. The only difference on those machines is that this security module is not there.

Try to rename/remove the secmode.db file in the Firefox profile folder with Firefox closed.

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.
