This tread helped me a bit as I have just installed firefox 27.0.1 on my EOL Ubuntu 10.04 computer. I extracted the new firefox.tar.bz2 package and then copied the new folder into a directory named /usr/lib/firefox 'I am not sure if that's the best place but anyways'. Then I pointed my Gnome2 launcher buttons to the new firefox.sh within the /usr/bin/firefox folder. I removed the old symlinks in the terminal and used synaptic to completely remove the firefox 20.0 from apt. P.S I probably should have done that first before transferring the new firefox version anywhere.
Then I downloaded the latest updated version of flash from the adobe website. I went into the directory /usr/lib/flashplugin-installer/ I then renamed the original libflashplayer.so to oldflashplayer.so and copied the newly downloaded libflashplayer.so into the /usr/lib/flashplugin-installer/ directory.
Things seem to work very well.
If anyone has more input as to a better way to do this procedure or a more clean way please let us know.
Thank you,
