Contrary to the original Keepass Helper addon, when we drag and drop the url to Windows Explorer, it does contain the additional hostname in it... This may be not wanted (I have to rename the url link file in Windows Explorer each time).
Also, the hostname does only appear in the title bar when the tab finish loading. For long loading tab, this can be an issue, we have to wait. Could you add the hostname at the beginning of the tab load, not at the end?
