## aboutconfig

The bare minimum to keep the old XUL-based `about:config` version available in Firefox 87+

Mostly copied from https://github.com/xiaoxiaoflood/firefox-scripts, all credit goes to them.

All credit goes to [@aminomancer](https://github.com/aminomancer/) for the idea and the code for registering a proper about: page!

## Installation

1. download and extract the [master.zip](https://github.com/earthlng/aboutconfig/archive/main.zip)

2. copy the files/folders from `installdir` into your Firefox installation folder and the `chrome` folder from `profile` into your profile directory

3. load `about:support` and click the button "Clear startup cache..." (not sure if this is really necessary)

4. restart Firefox

5. you can now access the old `about:config` via `chrome://userchromejs/content/aboutconfig/config.xhtml`

Optionally you can also let the script register an `about:cfg` page. To do that, copy/move `aboutcfg.jsm` into the `profile/chrome/utils/` folder

and uncomment the 2nd-to-last line in the `_autoconfig.cfg` file.


Now you can access the old about:config page at `about:cfg` !

### How it works

- `autoconfig.js` tells Firefox to load the autoconfig file `_autoconfig.cfg`

  - `_autoconfig.cfg` tells Firefox to load the `chrome.manifest` from the chrome directory in the profile folder

    - `chrome.manifest` registers a `chrome://` namespace `userchromejs`

      

      

#### original files + modifications made

Mozilla removed the old `about:config` in https://hg.mozilla.org/mozilla-central/rev/2e2f7a1fd4fa

see the above link for the original files:

- toolkit/components/viewconfig/content/config.js

- toolkit/components/viewconfig/content/config.xhtml

- toolkit/locales/en-US/toolkit/about/aboutConfig.ftl

- toolkit/themes/shared/config.css

The only modifications are:

1. hardcoding all the localization stuff from aboutConfig.ftl into config.js and config.xhtml

2. remove the unnecessary telemetry stuff from config.js
