This problem is often seen when Firefox updates.

Consider temporarily disabling Trusteer Rapport. Check with Rapport they may well have issued an update so that it may be used with Firefox 30.

I suggest you Ask Trustteer support to put their comments in writing or post them on their public website. I suggest and that you specifically mention

• The versions of
  • Firefox
  • Trusteer software
• And specifically ask if thy will be updating their software to be compatible with the current Release of Firefox. (Firefox 30) And if so when this will be available.

  • Currently this only updates their software for Firefox 29 http://www.trusteer.com/support/latest-updates
  • Their support listing only goes up as far as Fx 29 at present http://trusteer.force.com/PKB/articles/FAQ/supported-platforms?l=en_US&lang=en_US

I am sure Trusteer Rapport & the associated Banking sites will not wish you to use an insecure unsupported Browser and so they will expect you to use the current Firefox release.

John99,

Thanks for the answer, it does seem that Trusteer is a bit behind browser updates from Firefox. I was talking to Trusteer support at same time as Mozilla and got this answer from Trusteer and it works now. Seems they have a newer version up on website dated June 2014. Thanks for help!

From Trusteer: We recommend you uninstall Rapport's current version, use the Terminal to remove Rapport's old folders, and then install Rapport's latest version.

You can uninstall Rapport by following these instructions: http://www.trusteer.com/support/uninstalling-rapport-mac-os-x

Once Rapport is completely uninstalled, remove its remaining folders as instructed here: http://www.trusteer.com/support/remove-folders-mac

After completing this procedure, please download Rapport's updated version that can be found in this link: http://www.trusteer.com/support/rapport-installation-links

Please make sure to reboot your computer once the latest version is installed, and let us know if the issue was resolved.

Glad to know it is working again, and thanks for posting the appropriate links.

This by the way shows the Firefox Release calendar, as you can see normally Firefox will update every six weeks.
