how many Firefox extensions exist

As of 2026, there are tens of thousands of Firefox extensions listed on addons.mozilla.org, with many abandoned or unmaintained.

why are so many browser extensions abandoned

Extension development is often a solo-developer project with no revenue model. When the developer moves on, the extension goes unmaintained.

how does Firefox extension review work

Mozilla reviews extensions for security and policy compliance before listing them. The backlog can take weeks. Extensions are manually reviewed.

is there a Product Hunt for browser extensions

No good equivalent exists. producthunt.com lists some extensions but lacks depth and recency. The gap is a real market opportunity.

Researcher Installs Every Firefox Extension, Discovers Ecosystem Gaps

A researcher attempted to install and test every extension in the Firefox extension ecosystem (April 2026, 692 HN points, 77 comments). The project surfaced how many extensions are abandoned (last updated pre-2022), how the extension store review pipeline fails to surface quality tools, and how users have no good discovery mechanism to find the right extension for a specific workflow problem.
