How to Report a Software Bug to Mozilla

Bug reporting is an integral part of the Mozilla development process. There are many different ways you can report a bug to Mozilla, so we encourage you to take advantage of them. You can create a Bugzilla entry from the add-on in the Thunderbird toolbar or by opening the Tools menu and selecting "Report a Problem." Additionally, you can email a report directly to mozilla@mozilla.com with as much detail as possible.
If your Firefox crashes due to a software bug, it's important that you also submit a crash report. Try these steps:
1) Open your Firefox profile folder (see below), then right click on the file labeled "Crash Reports" and select "Send feedback about this file".
2) Click on "Submit feedback", then select "Severity High", type in a title for your message, and click on "Submit".
3) Mozilla will reply with an email confirming receipt of your report:

How to Report a Software Bug

You can report a software bug by using the "Report a Problem" tool. This feature is available at https://support.mozilla.org/kb/Contacting-Mozilla-Help
If you have a software bug on your computer, then you should be able to find the Report A Problem tool in the Help menu of your browser. This tool will allow you to submit information about that bug so that Mozilla can learn more about it and fix it if necessary. The website will ask for some basic information about what's going on with your computer, like whether or not your computer is crashing or experiencing slow performance.
