Hi dtops,

You already seem to be posting from Firefox (32 bit - that is good! ) on Windows 10.

Did you also see

• Make Firefox your default browser on Windows
• Change your Firefox search settings on Windows 10

Please post a reply if you still have problems and try to detail what you have tried and what is not working. Remember we can not see your computer.

Hi everyone, the reason I can use Firefox is that I made it my home page, I wanted to make it default, and using the instructions on Firefox, I clicked on web browser it would not give me any other options. Just tried it again and it seems to have worked. No idea, as I did exactly the same thing several times. Computers???!!! So thanks for all your advice and help. Much appreciated

You are welcome. Great that it is working again. Thanks for letting us know.
