I searched on Google but the tutorials I found said they had to paste the plugin in /usr/lib/firefox/plugins But this folder does not exist! Can someone help me?

where did you find this tutorial? Any link? – erch Feb 5 '14 at 17:43
Yes, any link. But I will not post here because it is in Portuguese (I'm Brazilian) and would not help much! – Patterson Feb 5 '14 at 17:47
I'd still paste it, we can use google translate to try and at least partially follow. I do it all the time! – slm Feb 5 '14 at 18:06
Are you on a 64-bit system? If so, you're looking for the folder /usr/lib64/firefox/plugins rather than /usr/lib/firefox/plugins. – WhiteHotLoveTiger Feb 5 '14 at 18:19
If it turns out you're on a 32-bit system, could you post the output of ls /usr/lib/firefox* ? – WhiteHotLoveTiger Feb 5 '14 at 18:25

Try the Slackbuild: http://slackbuilds.org/repository/14.1/multimedia/flashplayer-plugin/

You simply download the flash tarball: 32-bit or 64-bit, as well as the SlackBuild: flashplayer-plugin.tar.gz

From wherever you downloaded them to:

# tar xzf flashplayer-plugin.tar.gz
# mv install_flash_player_11_linux.i386.tar.gz flashplayer-plugin
# cd flashplayer-plugin
# ./flashplayer-plugin.SlackBuild

This will produce a package for you to install. At the end, it'll say something like

Slackware package /tmp/flashplayer-plugin- created.

Then just run

# installpkg /tmp/flashplayer-plugin-

That should take care of everything for you.

Package flashplayer-plugin- installed. I did it properly, but I still have problems, I can not watch a video from youtube to the end. The videos stop in the beginning and youtube says I need flash. – Patterson Feb 5 '14 at 20:42
That sounds strange. Do the videos play even a little bit, or do you get the error message right away? – WhiteHotLoveTiger Feb 5 '14 at 23:37

Download flash*tar.gz for correct architecture(x86/x64) from adobe website. Untar it like this:

tar xvf install_flash_player_11_linux.x86_64.tar.gz

Move libflashplayer.so to correct folder like this

cp libflashplayer.so /usr/lib64/mozilla/plugins/

/lib/ for 32 bit. Restart your browser. Done!

I know slackbuild-way is probably the proper way to do that. Although I have it working only for my user by copying the plugin to ~/.mozilla/plugins/.

Solved! I had to go this link https://www.youtube.com/html5. And I enabled HTML5.
