Directly after the update to Firefox 43.0.3, users with G DATA security software running on their system might be impacted by Firefox crashing repeatedly during startup. Affected users should download and install the latest version of Firefox from the Firefox download page to fix this problem.

G DATA is releasing a fix for this crash as part of their signature updates too, so please make sure that all components of your security software are up-to-date.

As a temporary workaround, affected users can also disable the BankGuard component within their G DATA product:

  1. Go to the Settings panel of your G DATA product by clicking the cogwheel button G DATA settings icon in the user interface.
  2. Go to AntiVirus > Web protection in the G DATA Settings panel.
  3. Disable the BankGuard browser protection setting and click OK.
GDATA Disable BankGuard

Afterwards try launching Firefox again.
