Diễn đàn hỗ trợ Firefox

When I click on a new tab, I get this black Google Search page, which I want to go to open my homepage. When I click on home, it does open my homepage. The image is attached. Any help on how to get rid of it would be appreciated. I do use New Tab Override, but it doesn't seem to be working.

in google and in other browsers when you have multiple tabs in a container you have an option to minify all tabs in the container. is there a similar feature for firefox,

thank you!
