Build Cross-Browser Extensions
What this is
Cross-browser extensions target Chrome, Firefox, Edge, Brave, Opera and Vivaldi from one submission, surfaced through getBrowserDownloads() — a function that returns the right download link for whichever platform a visitor is actually on, rather than making them hunt for the correct build themselves.
How it works
Building cross-browser means writing to the lowest common denominator of what each target browser's extension APIs support, or maintaining small per-browser variations where APIs genuinely diverge — getBrowserDownloads() abstracts the distribution side so you can focus on the compatibility work itself.
Holding BOT for this path
One BOT holding covers cross-browser publishing the same as any single-browser extension — the requirement is tied to you as a developer, not multiplied per browser target you choose to support.
