User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:59.0) Gecko/20100101 Firefox/59.0 Build ID: 20180323154952 Steps to reproduce: Edit and Resend functionality under Developer Tools is working inconsistent and making user to be confused and in a dead end. 1. Open Dev Tools. 2. Go to Network tab 3. Select under filters the "ALL" filter. 4. See that you are able to "edit and resend" the request. 5. Select any other filter, for example, "XHR". 6. Try to "Edit and Resend" a request while having this filter enabled. Actual results: When having any of the filter enabled, other than "ALL", the "Edit and Resend" functionality is not working, making the right panel to close instantly. Expected results: While hitting "Edit and Resend" we should be able to edit the values of the request, as before.

It looks like the edit and resend request is only applicable to some of the requests. But I will place this in the correct component for verification.

I also found this an issue too. Is this intended functionality or why can we not use Edit and Resend when a filter is selected?

It's took a time for me to figure out why "Edit and resend" sometimes doesn't work. Since you know workaround the bug is minor, but it's very frustrating when you see it the first time. The bug obviously in filtration system. When you press "Edit and resend", you create new request entry, that can be filtered out by current filter.

Thanks for the report! Yes, this needs to be fixed. It's already reported as bug 1377741 Honza
