Someone has shared a Picasa web album (Limited, anyone with the link), but I can't download it to Picasa. The following alert appears:

Firefox doesn't know how to open this address, because the protocol (picasa) isn't associated with any program.

I have Picasa 3.0.0 installed on Ubuntu 11.04, I remember it saying something about registering the picasa protocol with Firefox during the installation.

I have Firefox 6.0.2, and these settings are present in about:config;/usr/bin/picasa

Picasa is located here:

$ which picasa

Is there something I can do to make this work?

PS: I hope this is not off-topic here, and I can't find the "picasa" tag. Could someone please add it, if appropriate?

Reinstalling the Picasa application did not help... – Kuz Mitch Sep 14 '11 at 19:30
I'm having exactly the same problem with Picasa 2.7, Ubuntu 10.4 LTS, Firefox 3.6.23. In about:config, I have:;/usr/bin/picasa network.protocol-handler.external.picasa;true $ which picasa /usr/bin/picasa – user30024 Oct 23 '11 at 13:44
Somehow I have the feeling that the solution will involve MIME types. – Nathan Osman Nov 30 '11 at 0:53

I added a new mimetype to make it works Worked for me :)

Open firefox tab and type about:config

set network.protocol-handler.expose.picasa to false
set network.protocol-handler.external.picasa to true

to either /usr/bin/picasa or /opt/picasa/bin/picasa (/usr/bin/picasa is a symlink to /opt/xxx)

If the above doesn’t work for you then try the method which was mentioned in this post. It was originally meant as a fix for chrome, but works fine with firefox too.

Open the file ~/.local/share/applications/mimeapps.list (remember to back it up) and add the following under [Added Associations]


Thats it. Now choose “Download to Picasa”, you will get a popup to choose the picasa application, here browse until the location of the picasa binary. /opt/google/picasa/3.0/bin/picasa in my case

This does open Picasa when I click on a "Download to Picasa" link, but nothing happens afterwards, and I don't see any activity or an import screen/prompt. – Kuz Mitch Dec 23 '11 at 8:29
