I should mention that this is a problem when debugging Firefox for Android remotely.

In the case where it is not detected, does it appear if you close and reopen the WebIDE window?

Comment 3

[Casey Yee]

No, it doesn't seem to show up when I close and reopen.  

I usually encounter this when I restart Web IDE because of some issue (either connecting with the phone, slow refresh, etc).     The only resolution seems to be disconnect the phone, and reconnect.

Is this a regression from previous behavior, or has it always been this way since you've been using WebIDE?

Comment 5

[Casey Yee]

I only recently started using it for debugging FF android.     So this is new to me, not sure if it is a regression or not.

Okay.  This is known bug with the ADB server we use under the covers on OS X.  Other OSes don't seem to have this issue.  I have seen the same behavior with "adb devices" from the terminal: if the server wasn't running before the command, you have to replug the device for it to be detected.

I would suggest using the new Wi-Fi debugging[1] approach instead, which does not have this problem.
