  1. Open this page :
  2. Open Firebug and switch to the Script panel
  3. Place a BP line 2 of jquery.js
  4. Open the Command Line Popup, enter this expression : jQuery()
  5. Hover some variables / expressions in the Source Editor ("a" for example)
    => As you hover expressions, it opens a tooltip with the result of the expression in it.

Actual Result :
The evaluation of the expression adds a new entry in the location menu of the Script panel. It also slows down Firebug.

Expected Result :
No additional entry.

Try-build here:

In order to install it, download the file and open it in Firefox.



After debugging for a while with the new build, I can confirm the entries are gone, thank you.
FB still struggles when I try to select an expression (e.g. i == 0 && next == 1) and hover-evaluate it, but it's around line 21000 of the file, big JS files were always a soft spot for the debugger.
