Firefox inspector goes empty after a couple of requests

Question

I use Firefox inspector a lot, like all day, and now for some reason it works correctly then it goes blank as shown below. I then have to close it and reopen it but it goes blank after about 2 minutes so not a good solution.

Has anyone seen this before, is there a fix?

Firefox 32.0 (just updated, same in 31.0) Windows 7 Professional 64 bit

Answer 1

This bug in fixed in the latest Firefox. See:

https://bugzilla.mozilla.org/show_bug.cgi?id=945749 and https://bugzilla.mozilla.org/show_bug.cgi?id=1002280

This was triggered by an ID element starting with a number.

Opening and closing the developer tools resets it for a while.
