User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:50.0) Gecko/20100101 Firefox/50.0 Build ID: 20161208153507 Steps to reproduce: 1. about:plugins lists flash-plugin as present and up to date 2. preferences --> applications --> swf is set to run in Firefox using the swf plugin 3. clicking on a shockwave flash file cause the file to be saved rather than run. Actual results: .swf file is saved instead of being run. Expected results: .swf file should be run in Firefox.
In Firefox 50, which is what I'm using until the problem is fixed in Firefox 51, the swf file was handled correctly. In Firefox 51, if one changes the option to save the file, it will save the file. So, Firefox is correctly identifying that the file is a .swf file, but it is not run properly using the plugin.

swf like this? http://www.tuto-eanim.fr/nadine/creas_perso/roses_malicorne.swf Did you test with e10s disabled?

I cannot reproduce this. Loading the URL from comment 2 works correctly (windows).
I'm running Fedora 24 Linux. It fails there. I don't know what e10s is so don't know what to disable. The swf file in comment 2 loads a picture but there is no sound. The two swf files that fail are on my computer. I run a dual boot, so went into Windows, updated Firefox, and the two swf files worked. However, when I looked to see what version of Firefox was "up to date" in Windows, it said 50. Version 50 also works in Linux. One of the two files is a game called catch 33. When I run the online version rather than the copy on my computer, it works.
Okay, I looked up e10s on the internet. When I looked at browser.tabs.remote.autostart, it was already set to false. There was also browser.tabs.remote.autostart.2 which was set to true, which I changed to false and restarted Firefox. The problem persists with both set to false.

The problem seems to be that Firefox no longer recognizes the swf suffix on files that reside on my computer. When I added type="application/x-shockwave-flash" to the info for the file, flash-plugin correctly loaded and ran the file: <a href="file:///home/greta/public/globe.swf" type="application/x-shockwave-flash">globe</a>
Not reproducible with Firefox 51.0.1 on Windows. Linux only? Did you try to remove mimetypes.rdf and restart Firefox?
ok, we're not going to fix this then. We're also going to completely disallow loading plugins from file: paths in bug 1335475 for security reasons.

Seems to be Linux only. My Windows system uses a 32-bit Firefox; my Linux system uses a 64-bit. Removing mimetypes.rdf and restarting Firefox did not change the outcome.
I tested it with Win64 Firefox, not 32-bit. Anyway, this bug is now WONTFIXed.
