Firefox not working right after this update.

I do not use any FIrefox plug-ins and if you do, you might consider systematically uninstalling them one-by-one to see if that is causing collateral operational issues. Are you using any anti-virus application that may be introducing its needless restrictions on your browsing? I believe this to be a localized problem as I have no issues on Intel and M1 hardware with macOS 12.4.

After installing this latest update, in Firefox I cannot use javascript based sites, such as ordering a pizza at dominos.

Never had an issue with Firefox. See Firefox>About if you need to update this app

Did you try using a different browser to compare your results(?)

You can always if in doubt search the developers website or contact: Support/Help/FAQ/Known issues/compatibility/Updates

You do not explicitly state the version of macOS or Firefox, so latest is a moving target. I have installed FIrefox 100.0.2 on macOS Big Sur 11.6.6 and Monterey 12.4 and have no issues with the self-contained Firefox JavaScript support in the browser connecting to remove sites.
