Error when extension is deleted in webstore

[rEnr3n]

I have this extension installed and now it's gone - error 404. https://chrome.google.com/webstore/detail/olffebgbihkemhnlpeficnplfoiabljj

Version 0.4.3 should fix this. A warning is printed if such an extension is found but the script will continue to run.
