Steps to reproduce the issue:
- Install the latest version of DeArrow (2.1 at the time of writing this) from https://addons.mozilla.org/en-US/firefox/addon/dearrow/
- Go to YouTube
- Notice that most thumbnails are broken

- Install the same version of DeArrow on Firefox
- Everything works as expected

- Grab version 2.0.9 from GitHub https://github.com/ajayyy/DeArrow/releases/tag/2.0.9
- Repeat steps 2 and 3
- Everything works as expected

Expected behavior:
The latest version of DeArrow should function like it does on Firefox.
