Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

FireMonkey

  • Firefox only, and requires a recent one: version 93 on desktop, 113 on Android.
  • Not a drop-in replacement for Greasemonkey, Tampermonkey or Stylus. The project says so itself, so an existing library may need adjusting.
  • A much smaller user base than Tampermonkey or Violentmonkey, which means fewer people have hit the bug you are about to hit.
  • No Chrome, Edge or Safari build, so it cannot be the answer for anyone working across browsers.
  • Combining scripts and styles in one extension also combines the blast radius: one extension with permission to inject both into every page.

HTTPS Everywhere

  • Product discontinued as of January 2023
  • Functionality now built into all modern browsers natively
  • No longer receives security updates or maintenance

Answered from the vendors’ own pages

FireMonkey: What makes FireMonkey different from Violentmonkey?

It manages user styles as well as user scripts. The usual arrangement is a script manager plus a separate style manager such as Stylus; FireMonkey replaces both with one extension.

Source
HTTPS Everywhere: Is HTTPS Everywhere still maintained?

No. HTTPS Everywhere was retired in January 2023 because major browsers added native HTTPS upgrade features, making the extension obsolete.

Source
FireMonkey: Which browsers does FireMonkey support?

Firefox only. Desktop requires Firefox 93 or later and Android requires 113, with an API minimum of 102.

Source
HTTPS Everywhere: What functionality did HTTPS Everywhere provide?

The extension automatically redirected HTTP connections to HTTPS when available, improving encryption and privacy on unencrypted websites.

Source
FireMonkey: Is FireMonkey open source?

Yes, under the MPL-2.0 licence.

Source
HTTPS Everywhere: What is the recommended replacement?

Modern browsers including Chrome, Firefox, Edge, and Safari now include built-in HTTPS upgrade features that automatically redirect to secure connections, making HTTPS Everywhere unnecessary.

Source
FireMonkey: Will my existing Tampermonkey scripts work?

Not necessarily. The project states that while it shares functionality with Greasemonkey, Tampermonkey and Stylus, there are differences, so scripts and styles written for those may need adjusting.

Source
FireMonkey: What editor does FireMonkey use?

Current versions use the Monaco editor with ESLint, the same editor component that powers VS Code.
