Firefox not working? Here’s how to fix hanging tabs

Firefox users woke up to a rude shock Thursday morning: The browser refused to load any tabs in any respect, with each individual webpage returning an endlessly spinning “loading” circle in its place. Gah. Fortuitously, fixing the difficulty is easy.

The difficulty apparently stemmed from a way Firefox handles HTTP3 website requests. “It appears that a the latest update to the browser triggers an infinite loop in the network thread that helps prevent any internet pages from loading, leaving the browser ineffective,” The Independent noted this early morning, linking to an arcane configuration resolve to appropriate the difficulty.

I managed to affirm the deal with worked with my own Firefox set up, but luckily you should not will need to soar through technical hoops any more. Shortly just after eight a.m. eastern, Firefox’s Twitter account reported that only restarting the browser need to repair the concern now.

I hopped on a secondary Computer system exactly where I hadn’t applied the configuration tweak and can also verify that Firefox now works as expected. Phew. So if you are the sort of human being who leaves your browser and dozens of tabs open right away, just reboot Firefox and you’ll be superior to go. Concerned about dropping whichever you were being operating on in all those tabs? No issue. Mozilla clarifies how to restore tabs from a preceding Firefox session below.
