Firefox 156 opens PDFs 45% faster, plus a few annoying bug fixes

PCWorld reports that Mozilla Firefox 156 delivers a notable 45 percent speed improvement when opening PDFs, making the browser more efficient for everyday users. The update also brings better CPU and memory handling for large JPEG files, benefiting those on lower-powered hardware. Additional fixes address VPN connectivity stability and DNS over HTTPS issues, ensuring smoother and more reliable browsing overall. Today, Mozilla released Firefox 156 to the Release channel, which is basically all users in the general public. It's a pretty limp update by all accounts, without any standout new features and just a handful of minor bug fixes spread out across components. The built-in PDF reader launches about 45 percent faster than before, which is great if Firefox is your PDF reader of choice.
