I use firefox in my company to use the https://lidi.sisvida.com.br
system. However we use the "jsprint" plugin to print to the system. After the update the plugin is no longer compatible and I'm having to use the older version of firefox. We would love to use the new version because it seems to be faster.
Another site we use is http://saude.planserv.ba.gov.br/ace/ace001a.asp?tp_cliente=
. However this site is also not compatible with firefox.
