[qwerty12]

Tested with TWP 9.9.0.30 with Fennec F-Droid 119.1.0 on Android 12

Credits for the idea to use WebIDE is from here: arkenfox/user.js#1147

1. Set up ADB/Android USB debugging with your Android device - make sure adb is working with your device before continuing

2. Start Fennec on your Android device, go to the Firefox settings and enable the option Remote debugging via USB

3. Launch Firefox on the same computer ADB is connected to, and in it, go to about:debugging

4. Click Enable USB Devices and on the left of the Firefox Debugging page, you should see your Android device. Click Connect and select the device

5. Scroll down and click the Inspect button for the Multiprocess Toolbox entry

6. Click Console, and run the following:

const { ExtensionPermissions } = ChromeUtils.importESModule("resource://gre/modules/ExtensionPermissions.sys.mjs");
const addon_id = "{036a55b4-5e72-4d05-a06c-cba2dfcc134a}";
const policy = WebExtensionPolicy.getByID(addon_id);
ExtensionPermissions["add"](addon_id, { origins: [], permissions: ["webNavigation"] }, policy?.extension);

7. Go back to the about:debugging page and click the Inspect button for TWP - Translate Web Pages

8. In the Console for TWP, run await browser.storage.local.set({autoTranslateWhenClickingALink: "yes"});

9. Wait a second and restart Firefox on your device

In the TWP settings, the Automatically translate when clicking on a link that takes you to the same domain as the current site option should be set to yes.
