Permissions by site for add-ons - where are they stored?

I opened several links in new tabs and one of them wanted permission to install an add-on, which I refused. But that site opened pop-up and browser windows which, when closed, merely opened more windows, and a Powershell window too. It looked very suspicious, so I closed the browser entirely and didn't touch those windows. I want to report that site as possibly malicious, and see if it raises any alerts. But, in closing the browser I lost the site address. I know I clicked "never allow" for that site to install an add-on. Is it possible to see which address or site I most recently clicked "never allow" for? That is the only site that asked to install an add-on for at least a month. I tried re-opening all recently closed tabs again but couldn't find it. Thanks, Bernie

You can see allow exceptions in "Options/Preferences -> Privacy & Security", but blocked exceptions aren't shown there.

  • Permissions: Warn you when websites try to install add-ons -> Exceptions

Exceptions are normally stored in the permissions.sqlite SQLite database in the profile folder, so you can check this file in a SQLite viewer.

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.
