hello, websites will detect your location based on the public ip address your internet service provider assigns to you and they redirect you to local versions of their pages accordingly: http://www.yougetsignal.com/tools/network-location/

there's not much you or the browser can do to change that without using a proxy or vpn service to mask your location...

One solution might be to use Google search rather than typing domain names to bypass the "location sniffing" at those domains.

Bookmark http://www.google.com/ncr. This is an alternative web address for Google.com that always takes you to Google.com without redirecting you. Or install a Google.con/ncr search engine from the Mozdev Mycroft Project.

Some sites does indeed provide you localized content depending on few parameters. Some of them you can change easily, such as the Accept-Language HTTP header (Tools→Options→Content→Language, languages are sorted by priority there, so the first will be the most used), while some of these parameters are more difficult to control, such as websites that guess your location based on IP address and sometimes block content if you are not on the list of their target audience countries (Hulu, Netflix etc.).

While it is difficult to remove blocking, most sites that provide localized content allow the users to switch to other languages easily, and most of the times they store this user preference in a cookie.

For example:

Typing 'samsung.com' get me redirected to http://www.samsung.com/il/, and it is possible to change the language on the bottom-right corner of the page from "Israel/Hebrew" to other countries and languages.

Typing 'microsoft.com' redirects to https://www.microsoft.com/he-il/default.aspx and yet again you can change it at the bottom of the page.
