Generally speaking, Firefox directs searches to the .com site and indicates your preferred languages from the Options page. To review those settings:

Choose display languages for multilingual web pages

But Google search also has its own language preferences. If check this page, are they set to English:

https://www.google.com/preferences#languages

Hi jscher Thanks for your suggestion. I have ensured that I have English selected in FF Options & I have done Google. When I first open Firefox and search for an object, site etc in Google, I no longer get the Polish problem but the same page but in English. This mentions the use of cookies etc by Google and I cannot get rid of/ignore this page unless I set my preferences and agree.

When I exit FF it is set to remove all history etc, by default. I have not been using a computer for a year [in and out of hospital] so something has happened to my searching in Google. I know I had quite a few things to update.

That sounds like progress.

In the U.S., I have not seen Google ask for consent to set cookies. I think that is a special feature for users in Europe where the privacy laws are stronger.

Yes - some progress made. However, each time I open FF and Google search, I have to confirm/decline/accept their cookies. At least that page/pages are now in English. No wonder Google are facing a class-action lawsuit over 'Incognito Mode' - I don't think this effects me and my version of Google??? Thanks for your input - I have marked the thread as helpful and solved.
