linux and webvisum

[Linux for blind general discussion]

I have a webvisum account and need to solve a couple captions on a couple 
different sites.
What version of firefox will I have to downgrade to in order for webvisum 
to install?
Finally when I used webvisum last time it was on windows and it appears 
procedure for using it on linux is different.  Has anyone done this that 
could walk me through it?
