If you use the Firefox browser regularly, you may have noticed that this morning it is not working as it should. Don’t worry, it’s not your problem, but a global failure that is affecting millions of users.
The failure has begun to be detected around 9 in the morning in Spain, as you can see in the rebound in reports of problems with Firefox via Downdetector. And, while it is true that the Mozilla team is already working to troubleshoot using Firefox, it appears that the bug has not yet been resolved. Luckily, there is an option that we invite you to try that can solve this annoying bug.
Firefox does not work, but there is a solution
As we told you, when trying to open a web page in Firefox, you will see that it does not load. In addition, the Mozilla browser begins to consume a lot of resources, causing a saturation in the system that makes it impossible to use. Simply because the CPU is crashing and the rest of the programs on your computer will begin to fail.
It seems like, the problem the browser is experiencing has to do with a recent Firefox update this week, corresponding to version 96. In principle, it should improve different bufs and adapt to some versions of Linux that did not support this browser, but it seems that something does not work as it should.
Everything indicates that the problem is in the DNS, since when Firefox tries to find an IP address through these services, it cannot access them.
How to fix problems with Firefox
If you’re having trouble with #firefox, try disabling HTTP3 in about:config with the ‘network.http.http3.enabled’ key. After setting this and restarting Firefox everything worked again.

Fortunately, while it is true that at the time of writing this article the problem is still active Since Mozilla couldn’t fix it, there is a temporary way you can try to see if Firefox works for you again.
As you can see in the Twitter message that heads these lines, your Internet connection works perfectly, so If you want to keep using Firefox, you can.
To do this, what you must do is disable HTTP3 support, which is the latest version of the Internet protocol and is gradually reaching all web browsers. And it seems that in Firefox its implementation is causing problems.
So, if you want to use this browser normally until Mozilla solves the problems with Firefox connecting to the Internet, you must follow the following steps.
- Open the Firefox browser.
- Open a new tab.
- In the search bar, type “about: config” without quotes.
- Accept any prompts and enter “network http.http3.enabled” without using quotation marks in the search box.
- Now, double click on the option that appears so that the value changes from “True” to “False”.
- Close Firefox and check that it works normally.
In principle, these simple steps should solve the problem. If not, we recommend restarting your computer and checking that the Firefox connection problems have disappeared. A temporary solution while we wait for Mozilla to release an update that fixes these problems for Firefox to open a website.
