Hi,amboo8 can you update Firefox to latest version which is 29 and let us know if the problem still exists.And please tell us in what point Firefox crashes?The Firefox not responding or what? Regards.

I updated to 29 and Firefox still crashes. When it crashes, the browser completely closes and I get a "Mozilla Crash Reporter" dialogue box. This usually occurs as the page is loading (it never completes loading before crashing).

Maybe your problem is not with Firefox,but if is check you add-ons installed.Here are some screenshots to show you that i have no problem.

My problem is: when I invoke a certain website my PC powers off !! I get no warning no report .

This looks like a problem with content blocking software (EncTransportHandler.dll) possibly from ContentWatch

You can check what software has installed it and uninstall this software.

You might try disabling("never activate") two of your plugins which seem to cause occasional problems - Coupons, Inc. Coupon Printer 4.0.2.0 Catalina Savings Printer

I uninstalled ContentWatch and it worked. I'm going to contact ContentWatch directly to see if they can find a solution. Thank you so much for the help!
