Mozilla Shares Fix For Twitter Not Working On Firefox

Mozilla published a support document with a quick fix for a widely reported known issue causing Twitter not to load on the Firefox web browser.

According to a bug Mozilla has been tracking and working on fixing for the last 20 days, some users might see blank pages or errors when trying to visit the social network’s website, with some reports also saying that the issue also affects mobile users.

On devices where Firefox fails to load Twitter’s 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 adds. “Please contact the website owners to inform them of this problem.”

While Mozilla hasn’t shared the Firefox versions affected by this problem, affected users say [1, 2] that the loading errors have started to appear on both mobile and desktop devices after updating to Firefox 81.0 last month.

How to fix Twitter not loading on Firefox

“There is a known temporary issue on Firefox that causes a blank or error page when loading Twitter,” Mozilla explains in the support document published earlier. “We are working hard to come up with a fix.”

Until Mozilla’s engineers manage to fix this known issue, you can follow this procedure to get rid of the errors and blank pages 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.

Reports are also saying that hard reloading Twitter’s site using CTRL+F5 will also temporarily allow you to open Twitter pages.

Additionally, going to about:config and disabling dom.serviceWorkers.enabled will also remove the network violation errors.
