Mike Connor <email@example.com> has asked Ben Goodger (I don't read bugmail) <firstname.lastname@example.org> for superreview: Bug 131106: Make 'default browser' shouldn't steal image file associations from image programs http://bugzilla.mozilla.org/show_bug.cgi?id=131106 Attachment 139348: only take "default browser" types for Seamonkey/Firebird by default http://bugzilla.mozilla.org/attachment.cgi?id=139348&action=edit ------- Additional Comments from Mike Connor <email@example.com> http://lxr.mozilla.org/mozilla/source/xpfe/components/winhooks/nsSetDefaultBrow ser.js#78 specifies six things as "default browser" settings which are always set, but this part of winhooks makes a larger number default to on. This will not affect existing Mozilla installations, as those installations may modify the rest of this list in the advanced prefs, and future "set as default" actions use those settings. The exception is in the Prefs dialog button, where it will force these six on (as it should). For new users, however, we shouldn't take these by default. Other than win 9x/ME/early 2k versions, Windows has an image viewer that beats Mozilla. Worst case is that those users have IE for their images, and if they want to change it badly enough they do it via the prefs panel. In Firebird, Ben already said that we aren't going to have UI for this, if they want the image associations they can do it themselves via the Windows interface. We may want to consider for Firebird whether we should explicitly force the images off in the Set As Default Browser button so that existing users aren't affected. This needs to happen here as the default browser dialog uses these values, so product-specific changes won't be enough.
