For a while, devel­op­ing with new­er web tech­nolo­gies was risky because of Fire­fox. The ​“Can I Use” tables always glowed red for Fire­fox and, to a less­er extent, Safari.

But good news! Fire­fox have real­ly upped its game and is speed­ing ahead in not only bring­ing its brows­er up to speed but, in some ways, lead­ing the pack.

Interop 2026 brought Anchor Posi­tion­ing and Style Con­tain­er Queries. Both of which I’m tru­ly thank­ful for. For those who are new to Interop, it is essen­tial­ly an agree­ment between brows­er builders around which fea­tures are a pri­or­i­ty and must be in every­one’s hands.

Fire­fox have released a tool allow­ing web devel­op­ers to vote on which fea­tures they’d like to see released.

My vote is for border-shape and grid-lanes
