Hello bestmaliko8, Unfortunately you have picked up some malware, cause that "searchbaron" is a browser hijacker. Would you do this please : Go to the Firefox menu (≡) => Preferences => Add-ons => Extensions and remove anything that looks unfamiliar or suspicious. Next step : run malwarescans - further information can be found in this article : https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-caused-malware?cache=no '''Run most or all of the listed malware scanners'''. They all work differently - what one program doesn't pick up, the other might. Especially for Mac : https://www.malwarebytes.com/mac/ See this article for more instructions : https://www.fixyourbrowser.com/removal-instructions/adware/searchbaron-com/ (you'll have to scroll down to "Remove Searchbaron''.''com from Firefox")

Well said.
