How I can disable in Google client=ubuntu (in DDG t=canonical) in Firefox 47?
See screenshot:

enter image description here

UPD: That's all what i find about subj,

>strings /usr/lib/firefox/libxul.so | grep "client=" -n

208606: GetCacheSession for client=%s, policy=%d

but more interesting about Canonical partners. Seems, installing FF from official repo can negatively affect your right to privacy.

  • See if you can uninstall xul-ext-ubufox.

  • Hmmm... if that's really a problem for you, install Firefox 47 direct from Mozilla (mozilla.org/en-US/firefox/channel). That's what I'm using (for other reasons). It doesn't show "client name" in the search bar for Google. I don't use DDG.

I think what you are looking for is a "do not track" function. Firefox does have something that you could try and use.

See link It's disabled by default.

The Do Not Track feature is turned off by default. To turn it on:

Click the menu button and choose Options.
Select the Privacy panel.
Click manage your Do Not Track settings.
Check Use Do Not Track.
Close the about:preferences page. 
Any changes you've made will automatically be saved.

    Don't forget "individual websites are not required to respect it" - If you really want it to be completly without notice who you are maybe try using some kind of sandbox.
