Can you please try uninstalling Adobe Flash and Adobe Shockwave from your computer and then reinstalling the latest version on your computer again?

Please let us know if this fixes the issue.

The crashing thread involves Trusteer Rapport and Websense, with Websense "qipcap.dll" running later, so probably having more responsibility.

Unfortunately, Websense Endpoint is not supported with Firefox 40; the support matrix page says support is planned for a future release (http://www.websense.com/content/endpointproductmatrix.aspx) but here we are a few weeks after release and still...

If this is an unchangeable feature of your environment -- you can't disable Websense or roll back to an earlier version -- then you might want to try switching to the Extended Support Release version of Firefox (ESR). This is derived from Firefox 38 and while it will get security updates over the next several months, it will not get new features. Websense does say it supports Firefox 38.

If you decide to switch, here is how I suggest installing it:

Clean Reinstall

We use this name, but it's not about removing your settings, it's about making sure the program files are clean (no inconsistent, corrupted, or alien code files). As described below, this process does not disturb your existing settings. Do NOT uninstall Firefox, that's not needed.

(A) Download a fresh installer for Firefox 38.2.1esr from https://www.mozilla.org/firefox/organizations/all/ to a convenient location. (Scroll down to your preferred language.)

(B) Exit out of Firefox (if applicable).

(C) Rename the program folder, either:

(64-bit Windows folder names)

C:\Program Files (x86)\Mozilla Firefox

to

C:\Program Files (x86)\Fx40

(32-bit Windows folder names)

C:\Program Files\Mozilla Firefox

to

C:\Program Files\Fx40

(D) Run the installer you downloaded in (A). It should automatically connect to your existing settings.

Note: Some plugins may exist only in that old folder. If something essential is missing, look in these folders:

• \Fx40\Plugins
• \Fx40\browser\plugins

This report also contains technical information about the state of the application when it crashed.

I uninstalled Trusteer Rapport and ESR version 38 did work this time. Thank you very much for your suggestions and help! Tim Yasar

Glad to hear that your issue has been solved. Thanks for contacting the Mozilla support team.
