I found another browser extension called "Battlelog Plus" in this extension they enabled to save the loadouts maybe somebody likes the idea and makes a plugin for this extension! I was trying to run both but it got in conflict somehow!
Here is the website:
you can download there script from their homepage! Im not so good with programming :P to find the right code lines for the loadout!
I have no problem running B+ alongside BBLog. I actually think they're both needed to get the best from Battlelog.
We not copy features. B+ and BBLog work fine together. You should use it both if you like both.
Save loadouts will be added soon by battlelog itself.
