I am generating a file open dialog which allows the user to download a blob I have generated in code. This works fine but in Firefox the "from:" field on the open dialog looks like:
from: blob:
Is it possible to programmatically set this with javascript so that I can specify the domain the data actually originates from?
For example if the blob was generated from data on www.stackoverflow.com I would like the open dialog to look like:
from: www.stackoverflow.com
No, you cannot influence the "From:" description in the Save dialog. Otherwise folks would abuse this.
However, it is indeed unfortunate that blob URIs display this poorly. Consider filing a bug (or even creating a patch) to rectify this.
