Saw a similar bug listed for Linux (bug 50914), but no mention of other OSes (specifically Win95/98). I'm running (from Help|About):Mozilla/5.0 (Windows; U; Win98; en-US; m18) Gecko/20001027 . Expected behaviour: Helper Applications dialog lists all MIME file types, allowing user to click on one and edit/delete it. Actual behavour: Helper Applications dialog is blank. Note: the helpers *are* being properly added using "New Type..." button, they just aren't being shown. Here's how I discovered this: From the Preferences/Helper Applications dialog, I pressed the "New Type..." button, and filled the resulting "New Type" dialog with the following: Description: Compressed file File extension: zip lha lzh MIME type: application/zip Application to use: "C:\Program Files\Norton Antivirus\Navw32.exe" /download When I originally tried this, pressing the "OK" button had no apparent effect -- not even the dialog was closed. Pressing it again (and every time I try to "re-add" this type) gives a new dialog "Helper Application Exists" with the text "A helper already exists for the MIME type 'application/zip'. Do you want to replace it?" Selecting "OK" dismisses that dialog, but the "New Type" dialog remains open. I can only dismiss that dialog with the "Cancel" or "X" (close) buttons. But when I click on a link with that MIME type, it pops up a dialog asking whether I would like to open the file using the application I specified, or save it to disk. (Aside: the "Always ask me before opening or saving files of this type" is disabled. Separate bug/feature/not yet implemented?) Sample link: http://dark.x.dtu.dk/~grumbel/pingus/pingus-0.4.0-binary-win32.zip (Warning: it's a big file. It's the only one I could find in a pinch that was application/zip .)
--> preferences, perhaps backend? seeing as well on new trunk builds

This also happens in Linux. In fact I've never seen the Helper Applications preferences work any other way so I had always assumed they didn't work yet! The behaviour is exactly the same as what was described on Win 98.
I created a new user profile, and now the listing of helper applications shows, and adding new apps works as expected. Are user profiles incompatible between builds, or is something bigger going on?
If you have a very old profile, you might see this. Read comments in bug 50914.Thx! *** This bug has been marked as a duplicate of 50914 ***
