To debug websites / apps that open new tabs or windows it would be useful if the Firefox developer tools would support the firebug activation modes . To do network analysis / debugging it actually might be necessary: waiting for the tab to open, reopening the developer tools + network panel for the new tab and reloading the tab often isn't an option as the reload will produce different results from the initial load.  http://getfirebug.com/wiki/index.php/Activation
Seems like an interesting feature to consider!
Severity: normal → enhancement
Status: UNCONFIRMED → NEW
Ever confirmed: true
Although the title point to "Developer Tools", the main focus and people most interesting in is at "Network" and "Debugger" panels, such feature is well supported in a bunch of tools already but looks pretty difficult(long time missing) to have in both Firefox DevTool and Chrome DevTool, is it possible due to problem with the architecture?
