Getting involved

Want to contribute but don't know where to start? Here is a list of issues that are contributor friendly

Building the code

1. Install the latest Xcode developer tools from Apple.
2. Install, Brew, Node, and a Python3 virtualenv for localization scripts:

   brew update
   brew install node
   pip3 install virtualenv

3. Clone the repository:

   git clone https://github.com/mozilla-mobile/firefox-ios

4. Pull in the project dependencies:

   cd firefox-ios
   sh ./bootstrap.sh

5. Open Client.xcodeproj in Xcode.
6. Build the Fennec scheme in Xcode.

Note: In case you have dependencies issues with SPM, you can try to reset package caches and resolve package version.

Building User Scripts

User Scripts (JavaScript injected into the WKWebView) are compiled, concatenated, and minified using webpack. User Scripts to be aggregated are placed in the following directories:

/Client
|-- /Frontend
    |-- /UserContent
        |-- /UserScripts
            |-- /AllFrames
            |   |-- /AtDocumentEnd
            |   |-- /AtDocumentStart
            |-- /MainFrame
                |-- /AtDocumentEnd
                |-- /AtDocumentStart

This reduces the total possible number of User Scripts down to four. The compiled output from concatenating and minifying the User Scripts placed in these folders resides in /Client/Assets and are named accordingly:

• AllFramesAtDocumentEnd.js
• AllFramesAtDocumentStart.js
• MainFrameAtDocumentEnd.js
• MainFrameAtDocumentStart.js

To simplify the build process, these compiled files are checked-in to this repository. When adding or editing User Scripts, these files can be re-compiled with webpack manually. This requires Node.js to be installed, and all required npm packages can be installed by running npm install in the project's root directory. User Scripts can be compiled by running the following npm command in the root directory of the project:

npm run build
