This can be fixed
edit executeJS.js ("firefox profile 
folder\extensions\{7067a92c-1db4-4e5e-869c-25f841287f8b}\chrome\content\executej
s\executeJS.js")
function EJS_evalStringOnTarget

replace
return EJS_currentTargetWin.eval(evalString);
with
return eval(evalString,EJS_currentTargetWin);

this is because there are more than one javascript implementation
eval(code, obj) // old style

with(obj) {
    eval(code) // modern style
}

Unfortunately, modern style is not supported by all the firefox objects yet. 
Good old plain eval works better sometimes.
