I didn't provided any link in this topic :D
Also I didn't try this solution, since I don't use a left sidebar, all I can say is that looking at what ludwigt said in the link Manu provided, if I understand right, is something like this:
try to find this line in tc-scripts.js
767 > c && (g && h ? a(d).insertBefore(e) : g ? a(d).insertBefore(e) : a(d).insertBefore(f))
and replace the second
Now the problem is that customizr uses the min version of that script, so you have 3 alternatives:
1) change tc-script.js, then generate (with some tool, google will help) the min version and replace tc-scripts.min.js.
2) make that change in tc-scripts directly (it will be a bit hard, 'cause min scripts are hard to read)
3) change tc-scripts.js and find out where customizr enqueue the min script (inc/class-fire-resources.php) making it to call the non min version.
