Version: firefox-24.0-1.fc19.x86_64 Steps to reproduce: 1. Go to web site that uses JavaScript 2. Open Tools -> Web Developer -> Network 3. Do something on the web site that causes JavaScript to make a network request. 4. Double click on a request, opening a panel which defaults to the Headers tab. 5. Note the contents of the "Request URL:" field in the new panel on the right, near the top. The problem I am having is that if the Request URL is sufficiently long, there is no way to see the full value (especially the important part, near the end). Clicking, right-clicking, double clicking, and highlighting all have no effect. For some reason, I cannot make the panel any wider even if I make the window bigger.
There's a "Edit and Resend" button which provides full Request URL line.
