Hello guys, I have purchased a new computer and I am new to the world of the internet. I am using Firefox 13 browser to surf the internet. I want to say that my English is really poor and I want to install the add-on in the firefox 13 browser which can check my spelling mistakes which I do regularly. I want a good spell checker add-on for the firefox 13 browser. CAn anyone recommend me a few, thanks a lot.
