Plugins - Flash and other

[Manom]

Installed nice everything on Linux Mint maya,
except plugins.
Tryed all from wiki instructions but still nothing.
Reainstalled flash also nothing.

Can someone please explain where to copy plugin fies, and clear instruction ?

My Palemoon folder is in opt/palemoon

PS
Great browser, thanks for linux support.

[access2godzilla]

You should put Flash Player's libflashplayer.so in /usr/lib/mozilla/plugins and check the permissions. They should be readable by all users.

[Manom]

Solved.
Reainstalled and it worked, all plugins from firefof.
Anyway I disabled most of them

Thanks

Technically, /usr/lib/mozilla/plugins doesn't seem to solve it for x86_64. The correct path is /usr/lib64/mozilla/plugins and the files are already there on my system, but pm4linux doesn't see them in that path:

Code: Select all

$ ls /usr/lib*/mozilla/plugins
/usr/lib64/mozilla/plugins:
libflashplayer.so                      libtotem-cone-plugin.so
libgnome-shell-browser-plugin.so       libtotem-gmp-plugin.so
libjavaplugin.so                       libtotem-mully-plugin.so
librhythmbox-itms-detection-plugin.so  libtotem-narrowspace-plugin.so

/usr/lib/mozilla/plugins:

Is there some configuration that I should change? I just installed pm4linux and am still in the process of configuring and migrating.

So it seems you're a Fedora user. Have you made sure that:
- The version of Flash you've installed is 64 and not 32 bit?
- The permissions are correct (i.e. everyone can read the libflashplayer.so file)?

As a last resort, try:

Code: Select all

export MOZ_PLUGIN_PATH=/usr/lib64/mozilla/plugins

Well, I wasn't expecting to play Distro Wars with you. Yes, the Flash version is 64-bit. Everybody can read it. However, /etc/alternatives has nothing for *flash* in it, and there is no MOZ_PLUGIN_PATH currently defined, yet Firefox finds it just fine and Pale Moon is based on Mozilla so I was surprised that Pale Moon didn't find it.

So how does Firefox know how to find it and Pale Moon doesn't? Maybe there's another configuration -- other than MOZ_PLUGIN_PATH -- that I'm missing? Maybe there's a way to look for it that Pale Moon is missing?

First of all, is this a Firefox version from the repos? If so, it may have been compiled with extra parameters/code that specifically enable this.

FF builds by Mozilla do have this problem. It isn't PM specific. For example,
https://support.mozilla.org/en-US/questions/985662

Yep, straight from the Fedora system repo:

I really want to dump Firefox in favor of PM4Linux.

FF builds by Mozilla do have this problem. It isn't PM specific. For example,
https://support.mozilla.org/en-US/questions/985662

Interesting. Looks like that problem was a 32 vs 64 mixture. In my case PM is not trying the lib64 dir when not found in the lib dir.

I found out that Firefox does it in their startup script:

Code: Select all

MOZ_ARCH=$(uname -m)
case $MOZ_ARCH in
        x86_64 | s390x | sparc64)
                MOZ_LIB_DIR="/usr/lib64"
                SECONDARY_LIB_DIR="/usr/lib"
                ;;
        * )
                MOZ_LIB_DIR="/usr/lib"
                SECONDARY_LIB_DIR="/usr/lib64"
                ;;
esac

So, they modify their own launch variables based on system query. I notice that /opt/palemoon/run-mozilla.sh uses MOZ_DIST_BIN to set LD_LIBRARY_PATH. I don't know if PM uses a startup system query script.

When compiling code for system installations I set special library tree names in /etc/ld.so.conf.d/*.conf files. I don't trust using LD_LIBRARY_PATH because people can change that too easily. Such installation scripts simply put the relevant file in place. Obviously, that's for compiling and running compiled code, different from this problem, but that leads me to /etc/alternatives. I could try the MOZ_PLUGIN_PATH you suggested before, but I noticed /etc/alternatives has the following:

Code: Select all

$ ls -oh /etc/alternatives/*.so*
lrwxrwxrwx. 1 root 27 Feb  9 13:03 /etc/alternatives/libjavaplugin.so.x86_64 -> /usr/lib64/IcedTeaPlugin.so
lrwxrwxrwx. 1 root 34 Apr  1 08:24 /etc/alternatives/libnssckbi.so.x86_64 -> /usr/lib64/pkcs11/p11-kit-trust.so

So, do you recommend I set such a symlink? If so, might that be something that could be part of the PM installation notes? Or, is there a better solution, especially one that survives future upgrades of the system?

[access2godzilla]

[quote=""LReznick"]So, do you recommend I set such a symlink?[/quote]
You can use the alternatives system if you want to, but then, it doesn't resolve the problem at hand -- PM doesn't read the /usr/lib64/mozilla/plugins folder.

Or, is there a better solution, especially one that survives future upgrades of the system?

I'd set up things in this way:
/usr/bin/palemoon

Code: Select all

#!/bin/sh
PM_PLUGIN_PATH="/usr/lib64/mozilla/plugins"
if [ -z "$MOZ_PLUGIN_PATH" ]; then
    export MOZ_PLUGIN_PATH="$PM_PLUGIN_PATH"
else
    export MOZ_PLUGIN_PATH="$MOZ_PLUGIN_PATH:$PM_PLUGIN_PATH"
fi
exec /opt/palemoon/palemoon "$@"

This will become part of the pminstaller tool in the next release, due tomorrow.

Done. Works now. Thanks for your help!

[davodego]

I've the Same Problem, but the script dosn't solved it. Opensuse 13.1 x64. Firefox has all the plugins and about:plugins in PM shows nothing.
Please help...

[access2godzilla]

Although I did recommend setting up things in that manner, it would be better if you put that in /etc/profile.

You need to check where the path of the plugins are. Did you check the file paths for the corresponding packages?
