I installed flashblock plugin or upgraded to the Ubuntu customized version of the Firefox I do no know what caused that but I stopped having any flash video in Firefox 3.0 even after repeated installs using the deb and tar.gz packages downloaded from the Adobe website. I tried installing Opera and flash worked fine in that. That is when I noticed when running from terminal Firefox is displaying a lot of missing shared object) files, like this : LoadPlugin: failed to initialize shared library /home/aaaaaa/.mozilla/plugins/libflashplayer.so [libplds4.so: cannot open shared object file: No such file or directory] LoadPlugin: failed to initialize shared library /usr/lib/adobe-flashplugin/libflashplayer.so [libplds4.so: cannot open shared object file: No such file or directory] The idea is that in some way all the soft links to the *.so.1d or *.so.0d files are deleted. So I had to recreate them. The following link helped a lot to that end. https://lists.ubuntu.com/archives/ubuntu-mozillatea...
