Several computers questions, guidance, please

Can't help with the upper-case problem - perhaps look in your manual?

Firefox spell check.
Tools>Options>Advanced>General. Put a tick in the box 'Check spelling as I type'

When/if you get a wrong spelling it places a red dotted line under the word, right click on said word to get a suggested correct spelling.

oh good, thanks. I did FINALLY find all that, clicked it and guess what?

IT WORKS!
