It would be great to have capability to execute external user program to
filter/transform incoming files before displaying them in browser.

Use example: I have a file compressed or encrypted with non-standard
    software. The file has .html.my suffix. Also I have a program that
    takes *.html.my files from stdin, and writes decoded data to
    stdout. I want all the files with .html.my suffix to be piped
    through my program before displaying.

Configuration of the feature could look like:
  Input MIME type: (HTML, text, X-arj, etc., or ANY);
  File suffix: (.html.arj, .txt.7z, .bmp.rar etc., or ANY);
  Filter name: my_decompressor
  Program's output MIME type: (text, HTML, png, etc.; NOT ANY!)

This is wanted for processing emails as well. Could we change the summary to
reflect this, and confirm it as a New RFE?

Comment 3

[Thomas]

Do you mean like displaying PDF files in Acrobat Reader etc?

Comment 4

[Boris Zbarsky [:bzbarsky]]

No.  The idea here is to run through a program that would generate, say, HTML,
and display the program's output as you would any other web page.

I think that to the extent we want this it should be via extensions like pdf.js. Whether they process the content directly or pipe it through an external program is up to them.
