If they are so good at protecting privacy, why do they need to track which browser I'm using in their URL?
Who says they're tracking you?
They may include that so they can serve the page so it displays in every browser the same or they just want to know what the browser ratio is to their site.
We don't collect any personal information on our visitors. Nada. Zilch. Zero.
When you use Startpage, we do not record your IP address, we do not record which browser you are using (Internet Explorer, Safari, Firefox, Chrome etc.), we do not record your computer platform (Windows, Mac, Linux, etc.), and we do not record your search words or phrases. In fact, the only information we do record is an aggregate total of how many searches are performed on our website each day (a measure of overall traffic), and those overall traffic numbers broken down by language, and statistics on a purely aggregate level.
If it's such a concern, change it to pl=ff
for Firefox, or just delete it.
How did you end up with that?
By using the Custom plugin or Generate URL under Settings on StartPage.
BTW, yesterday it had Custom plugin there, now I've only got Generate URL ... ?
