After easy semi-automatic updates for many years, the last two updates (143.0.3 and 143.0.4 on Windows 10 64bit) have stuck showing "Downloading update -- 0 bytes" for hours. The first time I eventually gave up and used the installer from the Firefox site to re-install. This seemed to get me to 143.0.3 without losing any important data in my profile but was certainly the hard way! Now the same thing is happening during the update to 143.0.4. What's going on? Are other users having this problem? -- jclarkw P.S. -- How can you manually stop and update during the download process? -- jclarkw
