Firefox suddenly closes then reopens with a new homepage.?

[Bob]

I opened Firefox and then it suddenly closed and reopened with a new homepage of http://searchy.easylifeapp.com/?chplbf=1

I have not installed anything recently that could possibly have the chance to do something like this.
I then scanned my computer with malwarebytes to find nothing. There was also another indecent when Firefox suddenly closed and reopened with a new Add-on that I have never heard of before. I can't remember exactly what it was called but it was a misspelled word with different capital letters in it.
I searched that word and nothing showed up so I just removed it and forgot about it. Even then I didn't install anything suspicious that would cause that.
Please help me find out why this is happening.
I still haven't heard of crapware that suddenly changes stuff like that. You should have ready my response better to answer it more completly. GIT GUD.

You've had crapware installed. Download malwarebytes, install the free version. Run a full scan and delete everything it suggests. Reboot, scan again.

Now open up your browser and reset your homepage. Searchy will be there until you reset the page.
