hello, this sounds like a problem possibly caused by adware on your pc.

1. please go to the firefox menu ≡ > addons > extensions & remove any suspicious entries (toolbars, things that you have not installed intentionally, don't know what purpose they serve, etc).
2. also go to the windows control panel / programs and remove all toolbars or potentially unwanted software from there.
3. finally, run a full scan of your system with different security tools like the free version of malwarebytes & adwcleaner, which are specialised in adware and browser hijackers.

Remove a toolbar that has taken over your Firefox search or home page Troubleshoot Firefox issues caused by malware

It did not work! I want to know the jerk who came up with this ad ware. I cannot at all use my Firefox because of these issues!

could you go to the firefox menu ≡ > help ? > troubleshooting information, copy the contents of that page and paste them here into a reply on the forum? this might give us a clue what is going on...

Also, bear in mind that adware programs may have innocent names to try to fly under the radar. Try sorting the list by date to spot those. Here's how:

Open the Windows Control Panel, Uninstall a Program. After the list loads, click the "Installed on" column heading to group the infections, I mean, additions, by date. This helps surface undisclosed bundle items that snuck in with some software you agreed to install. Take out as much trash as possible there.

Also, did you allow time for the malware cleaners to run? The free ones listed in our support article (Troubleshoot Firefox issues caused by malware) usually take considerable time to run. If they finish quickly and especially if they require payment, you may have a serious infection. I suggest the specialized forums listed in the article in that case.
