Firefox is one of the most widely used browsers across all platforms, however despite its widespread use, it still has some limitations on Windows 10 and 11.
Many people have reported that Firefox lags on their devices, which may be a serious issue if you use it as your regular browser.
So, in this post, we’ll walk you through the few options for permanently resolving this problem.
