Some Firefox-Searchbar-Searchplugins are revealing the real "Accept Language" and the "real Browser"
Some Firefox-Searchbar-Searchplugins are revealing the real "Accept Language" and the real "User Agent":
For example if I search something within the Firefox-Searchbar with the Google-Searchplugin, e. g. the following address: http://aruljohn.com/details.php (what is stupid, but it's a test !!) then Firefox shows in its "awesome bar" the following resulting address:
As you can see, at the end of this www-address theres stated "DE" (for German language) and "firefox" (for the browser).
This means that
-
Google always knows the real language and the real browser from the www-address - irrespective of what the Torbutton settings for Accept Language and User Agent are !
-
If I click on one of the displayed Google-results (within the above mentioned page www.google....) then the clicked page will also receive the above stated page www.google.... as referrer and thus the real language and the real browser - irrespective of what the Torbutton settings are ! (Test it: click on the first result on www.google.... - which is the page http://aruljohn.com/details.php itself, and you will find under "referrer page" the above mentioned page www.google.... and the real AcceptLanguage and the real UserAgent)
Solution: a) ALL Searchplugins should be de-activated while using TOR a n d b) the Referrer should be de-activatd in Torbutton BY DEFAULT (not just offered as an option)
PS:
-
I know that Torbutton itself shows "Firefox" as User Agent so it's not a real disadvantage if the above mentioned page www.google.... does it too, BUT the at least real language "DE" would be revealed, what shouldn't take place !!
-
I also know that searches via the "Google-Searchplugin" are often not accepted by Google itself (for whatever reason) while using TOR - so that this problem will not arise very often.
