Great, but here is a bug report & fix for v1.5 Rated 5 out of 5 stars

Found a bug/typo in the call of _guessFileName when saving multiple files (line 475 of cacheviewer.js, if I didn't mess up the file too much).
Second parameter was this.__type instead of this._type

This review is for a previous version of the add-on (1.5.1-signed.1-signed). 


yes,It was a mistake, thank you find it. The next version fixed it. thanks again
