AdGuard가 Firefox에서 HTTPS 트래픽을 성공적으로 필터링하기 위해서는 브라우저가 AdGuard의 인증서를 신뢰해야 합니다. Firefox 버전에 따라 브라우저가 인증서를 신뢰하도록 하는 방법은 다릅니다.

Method 1

note

이 방법은 Firefox Nightly 90.0a1 이상 버전에서만 사용될 수 있습니다. Firefox의 베타 및 일반 버전이 v90에 도달하면 이 방법을 해당 버전에도 적용할 수 있습니다.

Firefox Nightly가 AdGuard 인증서를 신뢰하도록 하려면 다음 단계를 따르십시오.

1. Run the browser.

2. Go to Settings → About Firefox.

   

3. Tap the Firefox logo five times.

4. Navigate to Settings → Secret Settings.

   

5. Toggle Use third party CA certificates.

Method 2

note

This method will only work on rooted devices.

1. Install and configure ADB; On the Windows platform, Samsung owners may need to install this utility.

2. Activate the developer mode and enable USB debugging:

   • Open the Settings app on your phone;
   • Go to System section (last item in the settings menu). In this section, find the sub-item About phone;
   • Tap the Build number line 7 times. After that, you will receive a notification that You are now a developer (If necessary, enter an unlock code for the device);
   • Open System Settings → Developer Options → Scroll down and enable USB debugging → Confirm debugging is enabled in the window Allow USB debugging after reading the warning carefully.

3. Install the Firefox browser (release version);

4. Open the AdGuard settings (gear icon in the bottom right corner) → Filtering → Network → HTTPS filtering → Security certificate → Instructions for Firefox → Install for old versions;

5. Open the folder data/data/org.mozilla.firefox/files/mozilla using adb shell su and cd data/data/..., then browse to the folder named xxxxxxx.default and memorize its name;

6. In the specified folder we are interested in two files:

   • cert9.db
   • key4.db

7. We need to move these files to a folder of the browser where the security certificate issue occurred:

   • data/data/org.mozilla.<browser_name>/files/mozilla/yyyyyy.default.

8. The full command will look like this:

   • adb shell su
   • cp -R data/data/org.mozilla.firefox/files/mozilla/xxxxxxxxxx.default/cert9.db data/data/org.mozilla.<browser_name>/files/mozilla/yyyyyyyyyy.default
   • cp -R data/data/org.mozilla.firefox/files/mozilla/xxxxxxxxxx.default/key4.db data/data/org.mozilla.<browser_name>/files/mozilla/yyyyyyyyyy.default

   In case you received the system notification permission denied, you should first move the specified files to the permission-free directory. And after that you should move them to the necessary folder in your Firefox browser.

   The full command should look something like this:

   • adb shell su
   • cp -R data/data/org.mozilla.firefox/files/mozilla/xxxxxxxx.default/cert9.db sdcard/Download
   • cp -R data/data/org.mozilla.firefox/files/mozilla/xxxxxxxxx.default/key4.db sdcard/Download
   • cp -R sdcard/Download/cert9.db data/data/org.mozilla.<browser_name>/files/mozilla/yyyyyyyyyy.default
   • cp -R sdcard/Download/key4.db data/data/org.mozilla.<browser_name>/files/mozilla/yyyyyyyyyy.default

   If adb shell su does not work, you should try adb shell initially, and then su.
