youtube site crashes chromium and firefox

[altamir-uab-ufscar]

Hi. I'm facing a problem with chromium/firefox and rpi4 8 gb (bcm2711c0) under raspbian 32-bit.

First of all, I had been suffering of hanged youtube, instagram, where video content took forever and did not load, yet the browsers did not crash. Whenever such problem appeared, vlc became unusable for audio and video clips and I had to force reboot using reisub + alt + sysrq or wait over 7 min for a shutdown or reboot event to complete. Since then I did these steps:

• removed pulseaudio and installed alsa (with pulseaudio emulation for ff);
• switched to an aarch64 kernel (Linux raspberrypi 5.10.63-v8+ Add ASoC support for boards/HATs using ESS Sabre ES9023 DAC #1459 SMP PREEMPT Wed Oct 6 16:42:49 BST 2021 aarch64 GNU/Linux
  );
• disabled h264ify for all browsers;

Now youtube crashes chromium and firefox tab, but the system is still able to play video and audio in vlc after the crash.

Chromium ver. is 92.0.4515.98 (official) built on Raspbian, running on Raspbian 10 32 bits
Firefox ver. is 78.15.0esr (32-bit)
All os updates such as firmware, kernel etc. took place as usual and default, except for a call to rpi-update which since then I rolled back.

Terminal log for chromium-browser:

The system is configured with the default 64 mb of vram, but no matter how much I increase it, the problem persists.
