265518 - provide UI for switching/toggling External Protocol Request dialog

Status: NEW

(Firefox :: File Handling, defect)

Description

[sairuh (rarely reading bugmail)]

tested with 2004102109-0.9+ bits on linux fc2. once you turn off the External
Protocol Request dialog, there's no frontend for turning it back on. instead,
you need to go into about:config and switch
network.protocol-handler.warn-external.file back to true.

1. download a file.

2. open Downloads mgr dialog, if not already open.

3. click either the "open" link, or the location button, or select "open
containing folder" from context menu.

4. in the resulting External Protocol Request (EPR) dialog, select the checkbox
to remember to open the file manager (or launch the application).

this sets the pref to false for all file types handled by the external protocol
handler, so you'll never see the warning in the EPR again. which might be a bit
too lenient, security-wise.

after a quick check, this seems limited to firefox. in thunderbird, the helper
application ("opening <filename") dialog comes up for opening attachments,
instead of the EPR.

forgot to check in Thunderbird Options | Attachments | Show Folder: this button
in today's build does bring up the EPR dialog. (2004102105-0.8 on fc2)

reminder to self that thunderbird also sets
("network.protocol-handler.warn-external.file", false) once I select the
checkbox to remember (ie, don't ask again). removing that line from pres.js
resets it back to true.
