How To Fix PDF Files Showing Up As A Blank Page in FireFox

Recently, I realized that any PDF files that I was trying to view in my browser suddenly could not display. Whenever I click on a link to view a PDF file, I end up seeing a blank page. I didn’t do anything to Firefox, nor to Adobe Reader, and when I went to Tools > Options > Applications, everything was still under Adobe, so I didn’t understand what happened.

It was until I went to Tools > Add-ons > Plugins that I realized that Foxit had installed a PDF viewer plugin. So I disabled it immediately from the menu. Problem was, the plugin was still there because there wasn’t an option to uninstall it, and I didn’t like having it hang around.

The solution was to physically delete the plugin, and this you can do by searching for “npFoxitReaderplugin.dll”, or by going to your Mozilla Firefox plugins directory (should be in your program files folder, /Mozilla Firefox/Plugins), and then deleting the offending .dll file. Once you do that, just restart Firefox, and you should have your PDF displaying properly now.

How To Restart The Dock In Mac OS When It Crashes

Just the other day I was running a whole load of applications on my Macbook Pro, and I saw my memory usage and CPU usage spike up (it was due to a couple of Adobe AIR applications – Mac OS tends to be bad at running Flash and AIR). And right about then, I had leave, so I had to put my Macbook to sleep. Later, when I tried to wake up my Macbook, I found that my dock had disappeared and I couldn’t bring it back up. Using cmd+tab still worked and my various applications were still running fine, so I knew that it was a problem with the dock.

So I tried killing it with the following command. Just open Applications>Terminal, and type in the following command:

killall -KILL Dock

What this command does is to kill the dock process, and restart it. Voila – you now have a working dock again!
