Issue with Firefox & Flash Player Installation

Question

This topic has probably already been brought up but I need
some help, please! I can't seem to find anything that matches
exactly what I'm going though here.
Yesterday I did a clean install of Vista. (I had some missing
.dll files for some reason). I re-installed Firefox, and went
through with all the Windows updates, etc. and everything has been
fine. Today, I have been trying to install Flash Player through
Firefox (Flash player is working fine on IE). It goes through the
motion of downloading it from the Adobe site, and it also states
that the download is complete, but when I go to a website such as
Facebook, it's giving me a couple of messages. The actual site's
message is: "Flash Player upgrade required. You must download and
install the latest version of the Adobe Flash Player to view this
content." as well as I get the yellow bar up top from Firefox
saying, "Additional plugins are required to display all the media
on this page" and has a button to click saying "Install missing
plugins". When I click on either this button or the "Download
Flash" button on the actual webpage, again, it goes through the
motion of downloading it, but that's as far as it goes. In my
"downloads" window, it shows a bunch of times that I had downloaded
the flash player, but it doesn't even give me the option to open
the file.
Up until yesterday, I did in fact have flash on Firefox.
Another thing I noticed, was when I re-installed Firefox, the
download scheme is a little different (I don't have the download
box at the bottom of the window anymore and I'm not sure why or if
this is just a new version of Firefox that I didn't have before.)
In any event, when I would save the flash player during the
download, I tried a couple of different locations (desktop and
another location in C drive) but when I go to those locations,
there is nothing there.
Any help would be greatly appreciated.

Answer 1

I was having the same problem installing Flash 10 for Firefox
and getting the "Insufficient Disk Space" message. I believe this
happens to people whose main local disks have a name other than
"C:" Mine is "G:" I think the problem is that its an install
package that automatically tries to install it on a C: local disk
directory. There is no option to manually install it to a different
directory, so we seem to be out of luck.
However, I did find a link explaining how to manually install
it:
http://www.varesano.net/blog/fabio/installing+flash+player+plugin+firefox+without+having+a dministrator+access+or+premissions
At step 1. Right click the link and choose "Save Link As" and
delete the ".xpi" extension and type ".zip" to save the file as a
".zip" file.
Even though the instructions are for a different problem, I
followed the steps and it worked fine for my problem as
well.
