Useful but buggy Rated 3 out of 5 stars

This extension is very helpful. Selecting files via the browse button is inconvenient. Drag and drop is much more convenient.

Unfortunately, it is buggy. In the past it caused lockups at some pages. Now, those don't happen anymore, but it attempts to add files twice. Usually, this fails and you just get the file added once plus an error message which you have to dismiss. On some pages, files do get added twice.
