I'm not sure I follow. What is the exact thing that you type in the web console, what is the resulting output and what did you expect to see instead?

Tested on:
Build identifier: Mozilla/5.0 (X11; Linux x86_64; rv:30.0) Gecko/20100101 Firefox/30.0
Build identifier: Mozilla/5.0 (X11; Linux x86_64; rv:33.0) Gecko/20100101 Firefox/33.0

Steps to reproduce:
1. load any page in tab
2. show console (ctrl+shift+k)
3. type without quotation '[1].'
4. press tab key
5. [FAIL] "Empty string passed to getElementById()." message appears in console, pointing to resource://gre/modules/devtools/DevToolsUtils.js line 215

Expected result:
'<- no result' or completion list should appear

Notes:
* '1' in step 3 can be substituted by any non-negative integer in standard form (it works ok for negative number, fractional numbers,hex number, expressions other then number literals)
* it works ok on 'about:newtab', 'about:config', the bug appears on 'about:blank' or websites

I can reproduce that.

There are a number of such bugs about this warning 'empty string...'. Even putting try-catch around the code that iterates the document properties doesn't help.

We should probably get rid of the warning entirely.

This appears to be fixed by Bug 1216668

Sorry, but it still seems to be prevalent: Firefox 47 still getting this.
Firefox: 47
jquery: 2.1.3
one dropdown list in the code

This error was being triggered by the console itself.  If a page causes the error I'm thinking it should still show up - but to be sure can you paste the full error (with stack) and/or link to a page that causes the error?
