[Bug 1497843] [NEW] when setting firefox as default browser it becomes default app to open .PNG files

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

Hi,

I've had the unpleasant surprise to discover that if I play with the default browser to something else like Chrome, Opera or Vivaldi and the revert to either Firefox or Firefox Nightly (firefox-trunk)  then Firefox (or the nightly, depending on which I select as the new default) become the default program with which Nautilus (Files) tries to open .PNG files.
 
I suppose it might be related to their .desktop files. For example, Chrome and Opera have these Mimetypes specified, respectively:

MimeType=text/html;text/xml;application/xhtml_xml;image/webp;x-scheme-handler/http;x-scheme-handler/https;x-scheme-handler/ftp;
 
MimeType=text/html;text/xml;application/xhtml_xml;x-scheme-handler/http;x-scheme-handler/https;x-scheme-handler/ftp;

Firefox and Firefox Nightly:
 
MimeType=text/html;text/xml;application/xhtml+xml;application/xml;application/rss+xml;application/rdf+xml;image/gif;image/jpeg;image/png;x-scheme-handler/http;x-scheme-handler/https;x-scheme-handler/ftp;x-scheme-handler/chrome;video/webm;application/x-xpinstall;

 
MimeType=text/html;text/xml;application/xhtml+xml;application/xml;application/rss+xml;application/rdf+xml;image/gif;image/jpeg;image/png;x-scheme-handler/http;x-scheme-handler/https;x-scheme-handler/ftp;x-scheme-handler/chrome;video/webm;application/x-xpinstall;

(they're the same)
 
So I edited /usr/share/applications/firefox.desktop and removed the "image/png" bit and solved the problem for Firefox. The un-modified firefox-trunk.desktop file still has causes the problem. Weirdly enough, the default application to open .jpg files does not change.
 
Why does the firefox.desktop file require all the additonal "noise" when we have plenty of other applications to handle those mimetypes? The other browsers seem to do just fine with their shorter MimeType lines.
