Mozzplugger not working in Lubuntu 11.10

Question

I'd like to open a PDF in a Firefox tab. I've been able to do it with MozPlugger before updating to 11.10.

preferences -> applications

now scroll down, then I see always ask next to file.

I guess I need to change always ask to MozPlugger. To do that I need to find out where MozPlugger is. However, it wasn't in .mozilla.

Am I doing the right thing? How can I find out where MozPlugger is?

=======================================================================

FIX

sudo gnome-open /etc/mozpluggerrc # need to be root to edit

Find a pdf block and change to the following:

application/pdf: pdf: PDF file
application/x-pdf: pdf: PDF file
text/pdf: pdf: PDF file
text/x-pdf: pdf: PDF file
application/x-postscript: ps: PostScript file
application/postscript: ps: PostScript file
    repeat noisy swallow(evince) fill: evince "$file"

Open firefox's help -> Troubleshooting Information -> Click on Open Containing Folder -> Delete pluginreg.dat (You may need to delete your local $HOME/.mozilla/firefox/pluginreg.dat file for mozplugger to be enabled correctly after you update it. (It will get regenerated))

The last step was necessary for me.

Here is a fix that might not apply to your problem. It did solve my similar issue.

Checking you have the same problem :

• Type about:plugins in a firefox adress bar.
• Search for a MozPlugger category.

If you have the same problem I had they should be no such category.

Solving the problem :

• open firefox's help -> Troubleshooting Information
• Click on Open Containing Folder
• Edit pluginreg.dat
• At the end of the file, in a category called [INVALID], you should find 2 lines ressembling this :

can'tRememberWhat/mozplugger.so:$ 
lot'sOfNumbers:$

• Cut those lines and paste them just under the [PLUGINS] category.

Restart firefox and everything should be fixed.
