Thank you so much for the quick reply. I'll disable Norton Confidential and get back to the forum with the results.

I have had this problem recently. I use Kaspersky Internet Security, and never used Norton.

1. Enter about:crashes in the Firefox address bar and press Enter. A Submitted Crash Reports list will appear, similar to the one shown below.
2. Copy the 5 most recent Report IDs that start with bp- and paste them into your response here.

Thank you for your help!

If you have Trusteer Rapport installed, try disabling it and see what happens.

As I instructed it to closedown - so did Firefox !

Note that you can also check if there are updates for your Trusteer software in case this appears to be a problem with Trusteer and not something else.

I have just downloaded the up-to-date version of Trusteer. I am going out now, but will see what happens later this evening.

I have had Firefox open for just under an hour, and then it suddenly disappeared.

As I said I had downloaded the latest Trusteer software, and had it activated on one site (GMail) but not on the site I was visiting when it crashed.

There it went again, about 45 mins from switch-on.

Any developments? This is so annoying when it happens.

Good news, it hasn't crashed today! I have also downloaded an update. Hope the bug has been fixed.

I just began to have this problem - 4 times in 10 minutes. I use Paretologic, Panda, and Malwarebytes.
