i try fully disable ublock origin and all my extensions but its doesnt help

Go to about:config in the address bar and make sure that webgl.disabled is false.

Does it still happen in a new profile? An easy way to test a new profile is to install Developer Edition and see if it happens there or refresh your existing profile.

You can check the Web Console for webgl related messages.

like this?

in dev version it works

In that case, the easiest solution is to refresh your profile. If you want to salvage it, you will need to do some technical troubleshooting to find what is wrong.

Open the web console (Ctrl+Shift+K) after loading the site and see if there are any errors.

Go to about:config, type "gfx" and reset all listed items to default, then do the same for "webgl", then restart the browser.

doesnt help,after sync again web page stopped working

I turned of ETP and the site works for me. see screenshot https://support.mozilla.org/en-US/kb/enhanced-tracking-protection-firefox-desktop#

after turning this to weak this helps me and turning off uBlock Origin > Filter lists > AdGuard – Ads (default disabled). and not using clear urls and Privacy Badger extensions
