shouldnt be here at first line something like?

#!/usr/bin/env python

Good call, updated

(I found this because I wanted to clean my sqlite files without installing the sqlite3 command-line. There's a line of JavaScript you can run in the Firefox Error Console --

Components.classes["@mozilla.org/browser/nav-history-service;1"].getService(Components.interfaces.nsPIPlacesDatabase).DBConnection.executeSimpleSQL("VACUUM");

-- but it only cleans places.sqlite.)

Pasting parts of the script into the python interpreter command line, I found I had to remove the blank line 25 after return within def searchSqlite() or I'd get "IndentationError: unexpected indent".

One flaw in this script is it assumes your profiles are in the profilApp directory. If you've got profiles elsewhere, then a more comprehensive approach would be to parse profile.ini and use the Path value when IsRelative=0 to figure out where profiles are.

Anyway, thanks! I learned an extra smidgen of Python - 97% remaining :-)
