I'm running slackware 14.1.

I have /usr/lib64/mozilla/plugins/libflashplayer.so (Installed from alienbob's repo)

If I run firefox 38.8.0, it gets loaded

$ strace -e open /usr/bin/firefox 2>&1 | grep libflashplayer.so

open("/usr/lib64/mozilla/plugins/libflashplayer.so", O_RDONLY|O_CLOEXEC) = 48


But if I run firefox 47.0.1 it is not loaded.

$ strace -e open /usr/local/bin/firefox 2>&1 | grep libflashplayer.so


However, if I set MOZ_PLUGIN_PATH=/usr/lib64/mozilla/plugins, it works.

$ MOZ_PLUGIN_PATH=/usr/lib64/mozilla/plugins strace -e open /usr/local/lib/firefox 2>&1 | grep libflashplayer.so

open("/usr/lib64/mozilla/plugins/libflashplayer.so", O_RDONLY|O_CLOEXEC) = 44


38.8.0 is from the initial slackware install, and 47.0.1 is manually downloaded from mozilla.org, installed in /opt and symlinked to /usr/local/bin.


I've attached the "troubleshooting information" from 47.0.1.

How do I go about debugging this? Is this actually an issue, or is it just expected that I export MOZ_PLUGIN_PATH in my dotfiles?

Still here in 48.02. I symlinked `/usr/lib/mozilla` -> `/usr/lib64/mozilla` for now

Right, there IS a bug open.

https://bugzilla.mozilla.org/show_bug.cgi?id=549308

Going to mark this solved, and just follow the bug report for a real fix.
