167320 - eternal/endless/infinite loop when associating Firefox/SeaMonkey/Mozilla as a helper application for a given file type

Status: NEW

User-Agent:       Mozilla/5.0 (Windows; U; Win 9x 4.90; en-US; rv:1.1) Gecko/20020826
Build Identifier: Mozilla/5.0 (Windows; U; Win 9x 4.90; en-US; rv:1.1) Gecko/20020826

I think the download manager should either prevent the user from choosing
mozilla itself as "open with", or (better) figure out that the user wants the
file opened in the browser, not by the download manager at all.

Reproducible: Always

Steps to Reproduce:
1. download a binary file
2. choose mozilla.exe to handle file
3. uncheck the box 'always ask'
4. have fun...

An enhancement would be to have an additional choice in the download window ("What should Firefox do with this file?"):

"Attempt to display file"

This would force the browser to render it internally, using whatever fallback mechanisms the browser has, ignoring MIME type.

In most cases, this will work just fine.  There's a lot of websites out there that serve content that can be seen just fine in a browser, but for whatever reason has the wrong MIME type encoded, or has the EMBED tag around it, or something like that.  This confuses the browser, and so the user can't easily open the content just by clicking on it.

If there's already a bug open for this enhancement, please link it here.

In response to comment #19: the enhancement is in Bug 196078 for text/* documents, and Bug 57342 for everything else.

Would it not be possible to detect that the file open request came from the OS (command line parameter) and not defer to helper applications in that case, ie. error message.

Trying to detect the source or destination seems foolhardy.

(I'm not sure if this is the right bug. Bug 218257 Bug 215554 are newer.)

Maybe, but the problem is of course that the code that does the helper app launching doesn't know that the URL came from the command line, so this would require quite a bit of code changes.

Oh guys, I'm so sorry this was a dupe. I really did look at the list given and used the keywords of ".do open file" and "infinite loop" to try to find it but there was a list SOOOO long and it was definitely not in the first 100 that came back. I don't mean to fill up the system with dupes, but it sure would be nice to have this fixed! Thank you for checking it out. :) Your work on this browser is VERY appreciated!! Firefox is the best!

This bug is like an easter egg! 10 years old, critical but most people probably don't hit it ;) I hit it trying to open PDFs, it wasn't opening in Aurora so I tried choosing Aurora. It worked for the first PDF I tried it on, then the 2nd one looped :D At least the browser was responsive and I could exit (yay session store!)

I'm curious why we still allow FF to select itself and loop in such a way, especially considering how easy it is to do and it can effectively brick the profile (and system if it has low resources).
