Forced Google UK
Make the Google search result show Google UK results reglardless of your geolocation.
What is Forced Google UK?
Forced Google UK is a Firefox add-on that allows you to search on Google UK and view its results, regardless of your geolocation. It adds the 'gl=gb' parameter to the search URL, ensuring you get UK-specific results. You can also set Google UK as your default search engine or use the 'guk' prefix in your search for quick access to Google UK.
Basically, all it does is adding the "gl=gb" parameter.
After installing this extension, you may want to set "Google UK" as the Default Search Engine so that searching in the address bar will use Google UK. To do so, open the Options page, click "Search" on the left side, and then change the Default Search Engine in the drop-down list. Alternatively, you could just prefix your search with "guk" (without quotes) to search Google UK without changing your current default search engine.
Forced Google UK is relatively safe to use as it requires very minimum permissions.
Forced Google UK has earned a fairly good reputation and likely can be trusted.
