When reviewing files on my computer, html that used flash player, they will not work, while "most" other sites that use the same type of player do work. If I upload the html to my domain, it works perfectly.

It used to work before the dreaded 56.0.1 (64-bit) update, I'm totally in FEAR of any more Firefox updates that crash the browser.

I have turned off my updates, so that is NOT an option, I need to fix what I have.

Anyone have a fix so I can again work with these html files to edit etc?

This is possibly because the file:// protocol is disabled for plugins.

You can set this pref to false on the about:config page.

  • plugins.http_https_only = false

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.

Thanks! Like I said it was a problem since the dreaded 56.0.1 (64-bit) update. It's working like before the update. As a bit of information to you, the extension for all of these files is .htm not .html , I don't know if that also was a minor determining factor. (I'll have to test that.) But back to the :config, http_https_only=true, one would think the local files, ones on the computer, would not be within that restraint. After all, their either written by a user or considered safe because of virus or trojan protection. Thanks Again!
