About this extension
Steps to use this add-on:
1. Open Crunchyroll in two seperate windows, open the video in both windows and pause it immediately. Both videos must be at approximately the same timestamp (max. 1 second difference).
2. In one window select the desired audio language and in the other one the original language and the desired subtitle.
3. Mute the video with the subtitles.
4. Press "p" to start or stop both videos simultaneously. If your last click was on the time bar, you have to click somewhere else on the page, before pressing p works.

When pressing "p" both windows should be visible on screen. After both videos have started, you can minimize the window with the desired audio language and only watch the video with the subtitle.

Please note that it takes a moment for the videos to start/stop due to the synchronization necessary.
