|OK, let's have one more go at unravelling this.|
You have an XP computer which crashed. When it came back on again Chrome was missing. The THEY and THEM referred to messages that came up on the computer. In response #2 you were given a link and information to get Chrome back, if you want to.
Somewhere along the line it seems you installed Firefox on the computer too. From your posts I don't know whether this was before or after Chrome failed. Whatever, unless your computer crashes again it seems that the problem has resolved itself because you are now able to use Firefox instead (if you wish).
Is that right so far?
You are now adding that you have a Google Nexus 7 and that you "attempted to change it over". Do you mean you put Firefox on that too, or what? I assume that the power issue was also about the Nexus. It would be best to find a Nexas forum to discuss your issues with that.
Just for information, the internet is what your server provides. "Internet Explorer", "Chrome" and "Firefox" are all browsers which you use for access (surfing the web).
Is there still some computer problem that we can help with on here?
Always pop back and let us know the outcome - thanks
