everytime I open up a site this error message appears; it's closed and reappears with an option to not have it appear again which is checked and the message closed. It then does not appear again until I go to another site when the same thing happens.

I've used Firefox for years w/o any problem up to now.

If you get this on multiple sites that are not all part of the same network, it could indicate that one of your add-ons is not fully compatible with Firefox 19. Could you check for updates here:

orange Firefox button (or Tools menu) > Add-ons > "gear icon" > Check for Updates

If no updates are found, or the problem continues, try disabling all nonessential and unrecognized add-ons on these tabs:

orange Firefox button (or Tools menu) > Add-ons > Plugins category
orange Firefox button (or Tools menu) > Add-ons > Appearance category
orange Firefox button (or Tools menu) > Add-ons > Extensions category

You can save the step of restarting Firefox until you've worked your way through all 3 lists.

Any change?
