Firefox started to run an update. I immediately got the Parsing error: undefined entity Location: chrome//browser/content/browser.xhtml Line number 741, Column 15: I can’t even get to the browser homepage; sending this on my phone. All I get is a gray dialogue box with the message. Have rebooted. Try to open Firefox, reappears. This originated with Firefox automatically uploading an update without giving me an option to do later. Cannot access a browser page to download anything.
