Firefox Tekoha Aty

I have tried to up date the firefox program as requested. When I go hit the "update now" button, I get a screen and when I try to save it says " firefox installer already exists" and it takes me back to the first page with a message in a box at the top of the page that says Your download should begin automatically. Didn’t work? Try downloading again."

I have tried several times but I find that I'm stuck in a stupid loop where nothing gets installed. The message is that I have till March 14, so this needs to be done soon.

I am not particularly computer savvy, so any clarity on this will be helpful.

On my home page i have 2 rows of short cuts. Then the latest news listings. Can I change the types of news listings? For example one story might be from NPR while the next can be from CNN then another from MSNBC. Non of which interests me. Is there away to set sites in the settings to list News and events that I would be interested in? Sites like The Wire, Reuters, NewsMax, RT, The National Desk, etc. So would there be a way to get those headlines? Thanks
