One is a search engine and one is a web browser :/
I have a question for you -
Q: what is the difference between this question and a normal question?
A: A normal question has good grammer, go to school...
you just seach Google
Installing Google Chrome just gives you a stable Browser. The internet gets to the normal speed of running.
It depends on various factors of the system. Google Chrome is fast but it also takes a lot of space.
Firefox and Google Chrome are entirely different browsers. Chrome is much faster than Firefox.
You can not on google chrome, except for a whole theme. Which you can get on google. Otherwise, by logging in google you can put any picture as the background of the site : google. Hope, it helped.
You must sign out of your Google Account, or if you mean Chrome, then you must sign out of your Chrome Account. You can do that by typing in chrome://options.
Bookmarks in Google Chrome do not disappear without any issue. You could have deleted them or used a different profile.
No, you can download Google Chrome from Google.
Google Chrome and Internet Explorer both are web browsers. Chrome is much faster and stable than Explorer.
I've written a blog post on Disabling the Incognito mode in Google Chrome for both Windows and Mac. You can view it here: Disable Incognito mode on Google Chrome
Google Chrome can be downloaded via the official website of Chrome. You can type Google Chrome on Google and get the first website.
Google Chrome does not have it's own email system. However Google Mail and Chrome both are products of Google.
