What the product covers
The full FireMonkey feature record, grouped as the catalogue groups it. This is the product as a whole; the record does not map every feature onto a specific tier.

productivity

People bring FireMonkey in for running user scripts and user styles without two separate extensions, restyling sites with css alongside scripted behaviour changes, editing scripts in a full editor inside the browser, injecting css globally across every site, managing a mixed library of scripts and styles from one dashboard. If that is not the job you are buying for, the alternatives to FireMonkey are worth a look before you commit to a tier.
How that compares in Browser Extensions
Too few browser extensions tools in this directory publish a starting price to quote a meaningful median, so the table below is a like-for-like list rather than a ranking.
| Tool | Entry price | Model | Rated | Head to head |
|---|---|---|---|---|
| FireMonkey (this page) | Free | open-source | - | |
| Arc | Free | Free | - | vs FireMonkey |
| Hemingway Editor | Free, then $8.33/month | - | - | vs FireMonkey |

Ratings are aggregated from third-party sources and imported with each catalogue entry, they are not reviews hosted on Softwr. How each figure is used is set out on the FireMonkey badges page.
Before you pay for FireMonkey
Three things this page cannot tell you, and all three change the bill. The record carries a price and a billing period but not the unit - per-seat and flat-rate pricing are indistinguishable in this data, so a five-person team may be looking at five times the figure above. It carries no annual rate, so any discount for paying yearly is not something this page can quote. And it carries no trial length.
What it can tell you is the shape of the ladder: a single tier at Free. Because there is a free tier, the cheapest way to answer the rest is to use it before paying anything.
FireMonkey runs on firefox, and is published by FireMonkey. The full record is on the FireMonkey review, and the rest of the category is under best browser extensions tools.
