New tabs dissapear in browser

Hello , calling on site Techs to help me solve a puzzle . I have the most recent Firefox update, am using a HP M6 Pavilion notebook, Windows 10 . When I bring up a Firefox browser ( on both standard web , and Proton VPN service, has happened on both ), most tabs come up in a new tab normally , up to 6 tabs . When I try to bring up a new tab on certain websites ( like ) the tab comes up, then vanishes . On these particular sites, as long as I load another page from same website in same tab , first tab , they load, but If I try to load link in a new tab, it starts to load, then vanishes . Has me completely puzzled .
