FF does not load any page (including about:config or about:support)
OS: Windows Server 2008 R2 Enterprise with SP1
After the last updates (see list below) were installed , FF did not load any pages. This includes about:config, about:support, ... (about:preferences, about:addons is working only if called from the menu and not directly entered to the address bar)
I already tried reinstalling FF and also creating a new profile. Nothing helped.
When I close FF, the crash helper windows appears after a few seconds to minutes. Sometimes when running just one instance of FF a second FF-item in the task bar appears.
Please help - I need FF for certain applications, which work with neither IE nor Chrome.
Best regards & Thanks in advance!

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.
A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?
While still in Safe Mode,
In the address bar, type about:crashes<enter>. Note: If any reports do not have BP- in front of the numbers/letters, click it to submit them.
The crash report is several pages of data. We need the report numbers to see the whole report.
Using your mouse, mark the most recent 7 - 10 crash reports, and copy them. Now go to the reply box and paste them in.
For more help on crash reports, see; https://support.mozilla.org/en-US/kb/firefox-crashes-asking-support
Thanks for your reply.
about:crashes did not open when typed into the address bar.
But if I use the main menue to open "Help" > "Information ..." (sorry if not all menue items are named correctly - I use a german version here) then about:support opens and their I can call about:crashes and this link is working there.
But there I see that the last crashes were not sent, although I aggreed in sending each of them.

Did you start Firefox in Safe Mode first?
Start your Computer in safe mode with network support. Then start Firefox. Try Secure websites. Is the problem still there?

The computer is a citrix VM - so it's not easily possible to start it in safe mode.
In the meantime I did some research and found Bug 1433065 (https://bugzilla.mozilla.org/show_bug.cgi?id=1433065) which seems to fit my symptoms.
In detail, after implementing the suggested workaround (setting MOZ_DISABLE_CONTENT_SANDBOX=1) FF is working again and the issue does not occurr any longer.
But now plugin_container.exe crashes as the flash plugin is loaded ;)
I called for more help.
