Firefox has found a bug that prevents pages from loading and causes the browser to freeze

The problem can be solved in two ways. zavisat-15c142c.jpg” alt=”Firefox found a bug that prevents pages from loading and causes the browser to freeze” />

Users on the Bugzilla forum have reported that the issue occurs in the desktop version of Firefox 96.0 for Windows, Linux, and macOS. Refreshing pages takes several minutes, and when you try to close the browser, it freezes and stops responding to user actions.

Enthusiasts have found that the cause of the critical error lies in the Google Cloud Load Balancer cloud service or an equivalent from CloudFlare, which work with one of the Firefox servers. After updating, they encounter an HTTP3 data transfer protocol error that the browser cannot process correctly.

To solve the problem, you need to enter about:config in the address bar and go to the settings. The value of the network.http.http3.enabled parameter must be set to false – as a result, interaction with HTTP3 will be disabled. Another option is to go to the about:telemetry telemetry settings tab and disable all features here, then restart the browser.
