Using Mozilla Prism behind a proxy

July 30, 2008

Proxy settings can be changed by manually editing the configuration file all.js. In Windows this file is in the Prism\xulrunner\greprefs directory. The required changes are described in a number of places on the web, for example in a comment on the Mozilla Labs Prism page.

The default settings look like:

pref("network.proxy.type",        0);
pref("network.proxy.ftp",         "");
pref("network.proxy.ftp_port",    0);
pref("network.proxy.gopher",      "");
pref("network.proxy.gopher_port", 0);
pref("network.proxy.http",        "");
pref("network.proxy.http_port",   0);
pref("network.proxy.ssl",         "");
pref("network.proxy.ssl_port",    0);
pref("network.proxy.socks",       "");
pref("network.proxy.socks_port",  0);

and you want to change them to the following

pref("network.proxy.type",        1);
pref("network.proxy.ftp",         "proxy_ip_address");
pref("network.proxy.gopher",      "
pref("network.proxy.http",        "
pref("network.proxy.ssl",         "
pref("network.proxy.socks",       "

where proxy_ip_address and proxy_port need to be set to the proper values for your proxy.

Note What I didn’t find explicitly mentioned is that you have to

  • set the proxy values for all fields (ftp, gopher, http, ssl, and socks), and
  • use the ip address of the proxy (not its name)

At least Prism didn’t work for me if I set only http or use server name instead of its ip.

    I’m Susan, of the TechnoSnack’s team and I wish to inform you that we are opening a new blog aggregator about Computers & Internet news.
    We put it on-line some hours ago and the link is:

    The main objective of this project is creation of a “virtual dashboard” of posts coming from many specialized blog and information about Computers & Internet world, with news about Linux, Windows, Mac, Open sources, Security, Graphics, Symbian and more on…

    The key feature is that news come directly from blogosphere. We wish to show a preview of posts, with a link “Read more…” to signed blogs. If users are interested in news, they are redirected to your blog and can read entire post directly from your blog!

    So, the different signed blogs can increase their visibility and reach more visitors, all over the world!

    We think that in a little of time it can send more visitors to re gistered blogs, contributing to diffusion of know-how about Computer and Technology world.

    I visited your blog and I think it has very interesting and useful posts!

    So, are you interested in this idea, with your blog?
    If yes, then you can register your blog, using the specific “Registration Form”!


    The only thing we ask to you is to insert TechnoSNACK banner in your blog to promote this project. Or, if you prefer, you can insert a link in your blogroll.

    If you like (we whould be happy, but it is not mandatory :-), you can write a post regarding TechnoSNACK project in your blog, to promote this idea.

    Do you ever run into any weeb browser compatibility issues?
    A handful of my blog visitors have complained about my websote not operating correctly
    in Explorer but looks great in Safari. Do you have any
    adevice to help fix this issue?

  3. Link exchange is nothing else however it is only
    placing the other person’s web site link on your page at appropriate place
    and other person will also ddo same in favor of you.
