I tried to download firefox on my lenovo laptop, and it downloads and installs, but as soon as the download is complete it comes up with a message that Firefox has stopped working, I click the check online for a solution and it shows shows an application error; "The application was unable to start correctly (0xc0000005). Click OK to close the application."
