User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.4b) Gecko/20030516 Mozilla Firebird/0.6 Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.4b) Gecko/20030516 Mozilla Firebird/0.6 On any download, when Mozilla asks the user how to download the file, if the user chooses the same Mozilla application that is running, Mozilla will proceed to download the file in a new window. This action will repeat in the new window, downloading the file to another new window, which will never end unless the user closes all of those windows. This is important because this could be done by user error or from a user expecting Mozilla to handle the file internally for display. In either case, the user does not expect the application to open an infinite number of windows trying to process the file. Reproducible: Always Steps to Reproduce: 1. When downloading a file of a new type (i.e. first time I downloaded a .rtf or .zip file), click on the "Open it with" option. 2. Click on the now enabled "Choose..." button. 3. Choose the same application you are running. 4. Confirm the 'choose' and 'opening' windows. Actual Results: A new window pops up with a download box that, when the file is done saving, creates a new window with the file. This action happens infinitely. Expected Results: Mozilla should have either disallowed the user to select itself as a helper application, or, as the user intention may have been, attempted to display the document internally as best as possible (for example, I tried downloading a .rtf file in hopes that Mozilla would display the page in rich text format, or if not that, at least as plain text).

Martin, this can be also seen using Mozilla SeaMonkey (Windows; U; WinNT4.0; en-US; rv:1.5a) Gecko/20030603 - hence this one belongs to Product "Browser". Nevertheless this is an interesting effect :o)

Moving over to Browser

In Mozilla, the "always perform this action" check box must be clicked (or, in the "helper applications" section of the preferences, the "always ask me" check box for a particular type of file must be unchecked) in order for this to happen. No one has confirmed this bug yet, but I still contend this is *always* reproudicible. Although it is generally non-threatening and probably not commonly encountered, a user could easily run into this thinking Mozilla can handle the file internally (as I did! Silly me). I wager this also occurs on other platforms as well, but I have a lack of ability to test so (I'm also relatively new to Bugzilla... so I'm not entirely sure what should be done, if anything...)

tweaking summary to reflect what is really happening, moving to correct component. not sure if this is a dupe, but moving out of the morass of browser- general to hopefully increase the visibility. There's a Firebird version of the bug for that download manager too.
