Mozilla Releases Firefox 81.0.2 To Fix Twitter Errors

Mozilla released Firefox 81.0.2 today, October 13th, 2020, to the Stable desktop channel for Windows, macOS, Linux, and Android with a fix for a known issue preventing Twitter’s website from loading.

The issue affecting a large number of Firefox users caused the web browser to display blank pages or errors instead of loading Twitter pages on both desktop and mobile devices.

The Firefox 81.0.2 release notes say that this version “Fixed an incompatibility with Twitter.com manifesting itself with the intermittent display of a network protocol violation error page.”

You can update to Firefox 81.0.2 by going to Options -> Help -> About Firefox, and the browser will automatically check for the new update and install it when available.

Users affected after updating to Firefox 81.0

Even though Mozilla didn’t share the Firefox versions impacted by this problem, users said [1, 2] that the Twitter loading errors started to appear after updating to Firefox 81.0 last month.

On devices where the web browser failed to load the Twitter website, users would see “The site at https://twitter.com/ has experienced a network protocol violation that cannot be repaired” error.

“The page you are trying to view cannot be shown because an error in the data transmission was detected,” the error also read. “Please contact the website owners to inform them of this problem.”

If you can’t immediately update to version 81.0.2, you can follow this procedure to work around the errors showing up when trying to open Twitter:

1. Enter about:serviceworkers in the address bar (as shown in the screenshot embedded below)
2. Look for Twitter on the list then click its Unregister button.
3. Twitter should load the next time you visit it.
