I was able to reproduce the issue. Firefox crashes when the play button located at the bottom of the page is touched. This does not happen while using Chrome.

@softvision-oana-arbuzov @cipriansv Could you please have a look?

I'm not able to reproduce the issue on my side.

Tested with:
Browser / Version: Firefox Nightly 201209 (🦎 85.0a1-20201209034903)
Operating System: Samsung Galaxy S8 (Android 9) - 1440 x 2960 pixels, 18.5:9 ratio (~570 ppi density), Huawei P20 Lite (Android 8.0.0) - 1080 x 2280 pixels, 19:9 ratio (~432 ppi density)

I'll move to Needsdiagnosis based on the comment above, for further investigation.

Interestingly, it's working fine for me on the latest nightly build of Firefox on my phone, but the release build crashes. Does it also work for you now on the latest nightly build, @softvision-raul-bucata ?

It works fine now for me as well in the latest nightly build. On the build that I have tested then, I had 3 small crashes that occurred randomly that day on other websites, apart from the mentioned problem on the website. @wisniewskit

Since it works on the latest Nightly build I will close the issue.
