About 2 weeks ago, for no apparent reason, Firefox began exhibiting two problems: (a) it constantly tells me it cannot find whatever page it is I'm trying to load, or it loads the page without graphics. I have to reload once or twice to access whatever page I want. There's no particular type of page it won't load - news, facebook, whatever ... (b) after I've closed the browser, I get a crash message nearly every time. Each time I've sent a report, but nothing has helped. Sometimes I close it, then remember something and want to reopen it, and I cannot - I get a message saying it's in use and I should reboot. If I wait a while, then I get the crash report message and I can reopen then. I've tried all of the things suggested on the help page, but none of it works. I am running Windows 8.1 on a laptop that is less than a year old, and I'm using the latest version of Firefox. Also, I just tried installing the software for troubleshooting, as instructed on this page, and could not do it. The message said Firefox prevented installation due to a "connection failure" - of its own program. I could not do it manually, either, since there is no menu item at the top of my screen called "help," unfortunately. Can youhelp?
