Bug#842172: just install the latest version available on debian-server

Maybe we could make update-flashplugin-nonfree install the latest version which has a checksum on the debian-server available instead of just trying to install the latest version actually? What do you think?

Bug#845943: Unable to run, 'Error opening input stream'

I experienced the same issue. I was able to work around by removing Firefox and installing Firefox-ESR instead. $ sudo apt remove firefox $ sudo apt install firefox-esr $ sudo apt autoremove
