How do I set it to not go anywhere when I open a new tab

Not the home page, it is a new tab, but will most likely need cleaning up ''after'' fixing source of problem.
If you have an extension named "NewStart" uninstall it (question [https://support.mozilla.com/questions/856436 856436]). If you don't you will have to identify the cause of the problem.
After it is uninstalled check your about config filtering on '''somoto''' note any legitimate items seen there such as your old home page make a note, then delete every item with '''somoto''' (unless listed with a lot of other sites, such as sites to be blocked in the values, see Xircal's replies in [https://support.mozilla.com/en-US/questions/856436 856436])

Fix your homepage afterwards

If you have the Adblock Plus extension create a filter to prevent bringing up that site again create a filter. "||somoto.com/^" (without the quotes)
