WebEx Meeting Center stopped working with FF v.22


WebEx Meeting Center has stopped working since FF updated to v.22. I had this problem when FF updated to v.21 and I added a change to the plug-in load options in about:config called "plugins.load_appdir_plugins" and set that to TRUE and that corrected the issue under FF v.21.

Now that 22 loaded the other day, I cannot get the Meeting Center to run. I get the Java security warning asking if it is ok for this Java app to run and I allow it and then, instead of running, I get taken to the Meeting Center download screen even though the Meeting Center app is installed. This appears to be default behavior if the app doesn't start.

If I reinstall Meeting Center, it says would I like to Modify, Repair, or Uninstall and I've tried all options with removing and reinstalling and that has not helped. I've even removed and reinstalled Java and that has not helped.

Any suggestions, anyone?

Have you checked your plug-ins lately? To do this, go to the Mozilla Plugin Check site.

Once you're there, the site will check if all your plugins have the latest versions. If you see plugins in the list that have a yellow Update button or a red Update now button, please update these immediately.

To do so, please click each red or yellow button. Then you should see a site that allows you to download the latest version. Double-click the downloaded file to start the installation and follow the steps mentioned in the installation procedure.

plug-in's are all up to date. thanks for the response.

Try Firefox Safe Mode to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.

(If you're not using it, switch to the Default theme.)

  • You can open Firefox 4.0+ in Safe Mode by holding the Shift key when you open the Firefox desktop or Start menu shortcut.
  • Or open the Help menu and click on the Restart with Add-ons Disabled... menu item while Firefox is running.

Once you get the pop-up, just select "'Start in Safe Mode"

If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to figure out which one. Please follow the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article for that.

To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.

When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.

Thank you.

yeah, the issue is that the Meeting Center app for WebEx uses Java and if I start FF with all plug-in's disabled, won't Java be disabled as well? I can try this easily enough but I expect failure...
