Hi I have latest 50 f'fox. Since update f'fox crashes every single time. I cannot shop online as it crashes. It does not matter whether I have a single tab open or not.

F'fox will not load, or becomes responsive. It closes but does not restore ever like it used to.

I have uninstalled and re-installed. I have refreshed and checked all plug ins and ensured all up to date.

Problems started since new 50 version f'fox.

I have windows 7, 32 bit. F'fox uses over 1.5 Gb Help firefox warriors

Is the problem still there?

Some problems occur when your Internet security program was set to trust the previous version of Firefox, but no longer recognizes your updated version as trusted. Now how to fix the problem: To allow Firefox to connect to the Internet again;

  • Make sure your Internet security software is up-to-date (i.e. you are running the latest version).
  • Remove Firefox from your program's list of trusted or recognized programs. For detailed instructions, see

Configure firewalls so that Firefox can access the Internet. {web link}

Hi Guys

I have followed all advice. I followed Malawarebytes advice and uninstalled malawarebytes and ran their uninstaller. 

Did you mean uninstall anti-exploit? I have unistalled malaware bytes as well as uninstalling and then re-installing the latest version of anti-exploit.

Here are the crashes again

Hi Fred

You sent me a link to an AMD driver. I followed link but this link is for Windows 7 64 bit and for a graphics card that I do not have.

As I am not as technically knowledgeable I would appreciate some further help.

I have a Toshiba L300D-20R satellite pro, originally had Windows Vista but now running Windows 7 32-bit.

Processor: AMD ATHLON X2 Dual Core QL-64 210 Ghz

Installed Ram: 4.00 Gb RAM (3.50 usable)

The Grahics Card is ATI Radeon 3100

Driver for card is from ATI Technologies version 8.632.1.2000 from 17.08.2009

If I need to change this would you please send me direct link that is compatible with my system.

Thank you Fred
