Installation

Firefox Add-ons (recommended)

Install the official add-on from Mozilla: https://addons.mozilla.org/addon/quick-gpt-selected/

Manual install (legacy / testing)

Download the latest XPI from GitHub Releases:

• quick_gqt_selected.xpi

Go to 'about:addons' in Firefox. Click the settings wheel. Choose 'Install Add-on From File'. Navigate to the XPI and click 'Open'.

Legacy build:

• The legacy XPI is for older Firefox versions that do not support the latest manifest fields.
• If you need Firefox 134 or earlier, download:
  • quick_gqt_selected-legacy.xpi

Release checklist

1. Build the AMO (modern) package:
   • make xpi
2. Build the legacy package:
   • make legacy-xpi
3. Upload:
   • AMO: upload dist/quick_gqt_selected.xpi
   • GitHub Releases: attach both dist/quick_gqt_selected.xpi and dist/quick_gqt_selected-legacy.xpi

AMO source build instructions

The extension's own source files are plain JavaScript, HTML, and CSS. They are not transpiled, concatenated, or minified. The only generated third-party code included in the extension is the official KaTeX browser bundle, stylesheet, and fonts under src/vendor/katex/, copied from the pinned npm dependency katex@0.17.0.

Build environment used for the submitted package:

• Linux
• Node.js v20.16.0
• npm 9.2.0
• GNU Make 4.3
• rsync 3.3.0
• Info-ZIP zip
• jq 1.7, only needed for make legacy-xpi

Install the required tools with your operating system package manager, and install Node.js/npm from https://nodejs.org/ or your operating system package manager. Then run:

npm install
make xpi

This creates the AMO package at:

dist/quick_gqt_selected.xpi

For the optional legacy package, run:

make legacy-xpi

The build script is Makefile. It performs these steps:

1. Copies katex@0.17.0's katex.min.js, katex.min.css, fonts/, LICENSE, and package.json from node_modules/katex/ into src/vendor/katex/.
2. Copies the extension source from src/ into a temporary build/ directory, excluding editor backup files.
3. Zips the temporary build directory into dist/quick_gqt_selected.xpi.

Configuration

OpenAI (ChatGPT) API key needed: Open the add-on settings and add your OpenAI key.
