There is a problem that there are a lot of pinned tabs - create a sidebar for them

[agvozdezkiy]

When many pinned tabs are used, they take up a lot of space. It might be better to create a sidebar for them on the right or left. I was very pleased with the experience of using pinned tabs on the sidebar in Yandex browser. I would like to drag this fitch to mazilla.
