Hi there, Firefox shouldn't conflict with Edge. In order to assist you better, please follow the steps below to provide us crash IDs to help us learn more about your crash. '''The crash report is several pages of data.''' '''We need the report numbers to see the whole report.''' #Enter ''about:crashes'' in the Firefox address bar and press Enter. A list of Submitted (and Unsubmitted, if any) Crash Reports will appear, similar to the one shown below. #Copy the '''5''' most recent Submitted Report IDs that start with '''bp-''' and then go back to your forum question and paste those IDs into the "Post a Reply" box. ''' Note:''' If a recent Report ID does not start with '''bp-''' click on it to submit the report. (Please don't take a screenshot of your crashes, just copy and paste the IDs. The below image is just an example of what your Firefox screen should look like.) ;[[Image:Fx115aboutcrashes|width=500]] Thank you for your help! More information and further troubleshooting steps can be found in the [[Firefox crashes - Troubleshoot, prevent and get help fixing crashes]] article.
