Firefox সহায়তা ফোরাম

I can't reset my password. I reset my password for my main email but missed the box that popped up and needed a retry but it wouldn't open up for me again. How can I open that little box to reset my password?

When I am using the firefox browser and I click on a link to take me to duckduckgo.com or I enter duckduckgo.com in the url line and hit enter, instead of taking me to the duckduckgo website I get a white page with the message: Application error: a client-side exception has occurred (see the browser console for more information).
