I wish every browser (but mostly Firefox) had this new Chrome feature:
@bbatsov Firefox already has

@bartk Ha, I had totally missed this, even though I've been using Firefox for ages!

Probably because right now it's only an experimental feature https://www.omgubuntu.co.uk/2025/12/enable-firefox-split-view-feature Will check it out!

Firefox is Adding Split View for Tabs, Here's How to Enable It

Firefox's new Split View lets you browse two tabs side-by-side in one window. Enable this experimental feature in Firefox 146 now - here's how.

OMG! Ubuntu
@bbatsov Yes:) Combined with vertical tabs, it helps improve browser efficiency when you need to browse multiple pages at once.
