Their new fangled update schedule is highly problematic.
I am using Ubuntu GNU/Linux.
Using the Google Chrome Data Compression Proxy on non-Chrome browsers involves two steps.
proxy.googlezip.net
and port 80
.Chrome-Proxy
header into your request.The Chrome-Proxy
header should contain the following string:
ps=<timestamp>-<num1>-<num2>-<num3>, sid=<md5 string>, b=<build>, p=<patch>, c=<platform>
where:
0
<timestamp>
" + "<auth key>
" + "<timestamp>
"ac4500dd3b7579186c1b0620614fdb1f7d61f944
2214
115
win
"As an full example of the header you might have: Chrome-Proxy: ps=1439961190-0-0-0, sid=9fb96126616582c4be88ab7fe26ef593, b=2214, p=115, c=win
Now, to implement this practically, I think the easiest solution is to use an extension but there does not appear to be one for firefox that already has this functionality.
Therefore, I have implemented my own firefox extension for Firefox version 38 or above that allows anyone to use the Google Chrome Data Compression Proxy on firefox and am including the code below.
The following is the procedure that I used to develop and test the extension, and would allow others to regenerate the extension from scratch.
Get and install nodejs
Use npm
from nodejs to install jpm
via npm install jpm
Note that some versions of Ubuntu package node
as nodejs
so if jpm
can't find node
you may need to install another distribution of nodejs or create a link for node
to nodejs
Create a new directory for the extension and cd
into it
jpm init
Answer prompts with defaults
Replace your index.js with the code provided below
jpm run
Note that if jpm
is unable to find firefox in the standard locations, you'll also need to pass the -b flag to jpm
to tell it where to find your browser. (e.g. jpm run -b /path/to/Firefox/Nightly
)
You should now have firefox open with this new extension loaded and all traffic proxied through the Google Chrome Data Compression Proxy during this session.
Because jpm run
creates a temporary profile, you will need to jpm run
this extension anytime you'd like your traffic proxied. You could also jpm xpi
and Install Add-on From File
in Add-On manager.
You can verify that your data is being proxied by examining the response headers for the Via
header which indicates data being sent over the Chrome Compression Proxy (e.g. Via: "1.1 Chrome-Compression-Proxy"
)
You can determine how much data you are saving by comparing the Content-Length
header to the X-Original-Content-Length
header in server responses.

Under the "Tools" menu, choose "Options," activate the "Advanced" section, then select the "Update" tab; you'll be presented with a myriad of options for disabling or controlling how the updates behave as shown in the screen shot I've included from Firefox v3.6.23 below for your convenience (it looks the same in Firefox v7.0.1, so I'm assuming it isn't any different in Firefox v6.anything).
What problems are you encountering with the update schedule, by the way?
