Often you wanted to install the flash plugin for firefox, but end up with receiving "Administrator privilege needed", or install failed or sumthg similar. Here's hoe you can install the plugin manually with few steps! :)

• Download the Flash Plugin XPI archive to your computer.
• unzip the archive (you can use winrar or the free 7zip)
• copy the files flashplayer.xpt and NPSWF32.dll to your \Mozilla Firefox\plugins folder
• restart Firefox and enjoy!
• Alternatively, you can download the flash player from Adobe Flash Player website , and use the powerful free Universal Extractor to extraxt the installer and procedd with the third step
  

I've tested this with firefox 3 and it works like charm :)

I'm glad to hear any comments or suggestions :)
