After several days, Firefox has been updated since it was opened, but the update is not complete. In addition, all extensions and plug-ins are missing. This error is prompted when the extension is updated:
Error: E. location. getitemlocation (E. ID) is NULL source file: // C:/program % 20 files/Mozilla % 20 Firefox/components/nsextensionmanager. JS line: 3532
I am very depressed. I searched it by Google who moved to Hong Kong and found that all of them are in English. I don't have any Chinese. Is this a problem for all Chinese? I am so lucky to be the first? After thinking about a lot of methods, I finally unmounted a few useless extensions. I also found an extension of coffee (I installed the coffee antivirus software). I also uninstalled it, I forgot the name of this extension, but I couldn't see it after I uninstalled it. After I restarted it, I felt that Firefox was much more normal. This time the update was successful. I sent a post to tell my friends who encountered this problem.
