When I open a new tab in firefox 15.0.1, I get a a series of empty boxes ( 3 wide X 3 deep) on screen captioned with the titles of the most popular websites I look at. This is very annoying as I have to click on the LH bookmarks pane to go to a site I want. The odd thing is that when I first open firefox, it takes me to my ISP home page, which suits me fine.
How can I get Firefox to take me to the ISP homepage each time I open a new tab. It's not helping that I can't remember how to get select the home page settings.
Apologies, I've just reread your Q & I missed the part about setting the home page.
Click the orange Firefox tab (top left) then "Options". In the "General" tab, next to "When Firefox starts", select "Show My Home Page" & enter the address you wish, for example - http://www.theanswerbank.co.uk
