Debug Flash with Firefox (FlashBuilder 4.7)?

It's been awhile since I've had a Flash project, but lo and behold now I do! I'm trying to get up and running with FlashBuilder 4.7 and FireFox. However, whenever I go to debug a project, FireFox claims that no Flash Player is installed and FlashBuilder isn't able to make a connection to the debug player.

I seem to recall having this issue before, and thought it might have something to do with security issues with FireFox opening local files and executing JavaScript.

At any rate, I can't figure it out. Does anybody know a solution to this? Thanks!

Solution

  • I was about to put the same question to Mozilla, but found this in the process (annoying that it did not come up in a Google search).

    1. In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful.
    2. In the search box above the list, type or paste plug*ht and pause while the list is filtered.
    3. Double-click the plugins.http_https_only preference to switch the value from true to false.
