I get this error message "FirePass Web Access protocol error" on a site that used to open just fine.
I started using LastPass to auto fill the log-in but removed the site from LastPass when I started having this problem. I can log on to the site OK but there is a look-up app once I am logged in that gives me this error message. I can log in and access the look-up app OK on my laptop, just not my desktop.

Start Firefox in Safe Mode {web link} While you are in safe mode; Press the Alt or F10 key to bring up the tool bar. Followed by;
Windows; Tools > Options Linux; Edit > Preferences Mac; application name > Preferences
Then Advanced > General. Look for and turn off Use Hardware Acceleration.
Poke around safe web sites. Are there any problems?. Then restart.
