Reproducible: Always Steps to Reproduce: Step 1: install the popular MDL Chime plug-in that the biochemistry community uses like all the time... After attempting to download a PDB file from the PDB website (http://pdb.org/), the MDL Chime plug-in which was previously associated with viewing .pdb files is no longer invoked to display local .pdb files. An example of such a download URL: http://www.pdb.org/pdb/download/downloadFile.do?fileFormat=pdb&compression=NO&structureId=1A0Z On selecting this URL as a link the user is prompted to (defaulted option) "open with Internet Explorer (default)", or (not selected) "save to disk". After saving to disk, further Firefox handling of this kind of file changes, even though the "automatically perform" checkbox was not selected. (The file was successfully saved to disk, if it matters.) Accessing a .pdb _URL_ still results in invocation of the plug-in and successful display. Good. Accessing a local file is now different, however. Either invoking Firefox and the MDL Chime plug-in via Windows Explorer association or opening the file via the Firefox File->Open File option results in a dialog asking how to handle the file. This dialog now has "open with Internet Explorer (default)" not selected, and "save to disk" as the default. But disk is where I got the file, and opening with IE, I think, really means use Windows's file association, which for .pdb files is Firefox, so that up pops another Firefox tab and yet another one of these dialogs. Thus broken. Actual Results: File handling for PDB (.pdb) files changed. Expected Results: Not change handling. E3Joking aside, I imagine there's a substantial userbase out there with MDL Chime and I'd love for them all to be able to use Firefox. I'm surprised I couldn' t find a report for this bug. It's been around for If it's too much hassle to download the plug-in for testing (which I'm not sure is necessary to fix this bug ), email me please. Here's what the server was sending for the download link: HTTP/1.1 200 OK Server: Apache-Coyote/1.1 Set-Cookie: JSESSIONID=C01444B92F4A543E012F5A3DE5411E53; Path=/pdb Content-Disposition: attachment; filename=1A0Z.pdb Content-Type: application/download Content-Length: 432783 Date: Mon, 12 May 2008 23:00:41 GMT Connection: close And here are my Windows associations for this file and type, if it's relevant at all: C:\>assoc .pdb .pdb=pdbFile C:\>ftype pdbFile pdbFile="C:\Program Files\Internet Explorer\Iexplore.exe" %1 I don't know why it says Iexplore.exe here, as executing a .pdb from command shell or Explorer still invokes Firefox.
My text is a wee mangled because I had to recover it from a core, sorry. I didn't complete saying this: The bug has been around since at least May of last year. I'm surprised I didn't find a report.
Content-Type: application/download I suspect chime does not register to handle this mime type. The server needs to deliver a mime type chime understands. You can see the types chime handles in about:plugins
It is my understanding that the server is using a type to enable the browser to _save the file locally_. The aforementioned URL is used when a user is interested in "Download Files - PDB text". Here is the referrring page, to give some context for the aforementioned URL: http://www.pdb.org/pdb/explore/explore.do?structureId=1A0Z I imagine the Chime plug-in should not actually attempt to handle this type since the objective is to save the file locally. Perhaps pdb.org should be using a different type -- is there a canonical "browser should save this to disk" type for file downloads? After the user receives the download and opts to save it, local handling of .pdb files breaks.
More info, if it matters: This bug was known to users in mid-2006: http://www.bioinformatics.org/pipermail/molvis-list/2006q3/000303.html I think I started personally experiencing it on Jan. 28, 2007. Maybe with my installation of 1.5.
The page has one link that delivers it as application/download and one that delivers as text/plain. Both are not something chime understands. See http://www.life.uiuc.edu/crofts/bc1_in_chime/chime_talk/chimehelp2.html#Install5
I am not being clear enough. Please allow me to state the issue more simply: Clicking http://www.pdb.org/pdb/download/downloadFile.do?fileFormat=pdb&compression=NO&structureId=1A0Z breaks LOCAL viewing.
OK. You might try a FF3 build to see if the problem has been fixed since 2.0: ftp://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/3.0rc1-candidates/build1/firefox-3.0.en-US.win32.installer.exe
3.0rc1 appears not to have the bug. Wait... rc1? Is 3 really that close? Sweet.
