A common problem regerding flash-plugin in firefox-solved!

It's very common that suddenly the flash-plugin in your firefox browser stops working and whenever you open sites requiring flash (e.g. youtube) pop up with messages like : "Ether javascript is not enabled or you have an older version of adobe flash" ... but you check your browser settings and find that javascript is enabled and start to wonder. You then install the latest version of flash through yum or an rpm package but the problem still remains!!

So here's a solution to your problem: Download the .rpm or .tar.gz package from the adobe site and extract it. After browsing through the folders, you would find a file named "libflashplayer.so ". Next,make a directory named "plugins" in /usr/lib/firefox (Note: make this directory in the newest version of firefox if you have updated firefox e.g there might be firefox 3.0.5 and firefox 3.0.10, so make the directory in firefox 3.0.10 ) Just copy this fle into /usr/lib/firefox/plugins.. Close your broswer and restart it ,then check by typing "about:plugins" in the address bar of your browser,you will find a heading "Shockwave Flash"... Well thats it, it done! ... try opening youtube and see a vedio ! hope that helps.......
