I am trying to login to one of my online banking websites and I am getting this message "Firefox prevented this page from automatically reloading" and when I hit the ALLOW button, nothing happens.

OK, I sought help from Gemini AI and was advised to do the following:

1. Open your Firefox browser and type about:config into the address bar, then press Enter. 2. Click the warning button that says Accept the Risk and Continue. 3. Type accessibility.blockautorefresh into the search filter at the top. 4. Locate the preference in the results list and click the Toggle button (or double-click the row) to change its value from true to false. 5. Close your tabs and restart Firefox to apply the change.

Problem solved for the banking website ... not sure if this setting adjustment, can be confined to problem websites to preserve security?

You had it set to a non–default value (perhaps following some "good advice" online tutorials for unrelated things, recommending flipping a bunch of prefs without clear steps how to revert them back later on if that's not the thing you're looking for) — for something that might have been a dark pattern decade(s) ago but sites don't generally use anything like this today (there's better technology available since) so this accessibility preference to ignore meta refresh has been shipping disabled.

You can keep it disabled safely.

That's how everyone's Firefox comes out of factory anyways.
