If there is a star at the right or left of the URL at the top, click on that.

He is using Chromium, not Chrome. My Chromium has Bookmarks and a Star to
Add bookmarks to the right of the url window. Perhaps this happened as a
result of settings being reset. Try adding a Bookmark and see what happens.
Does it show? Try the Bookmarks Manager by clicking on the wrench and see if
you have any bookmarks. If not then I would completely remove and reinstall.
Backup first if the bookmarks are there, but not showing for some reason.

Chromium is the open source project behind the Google Chrome browser
so the two are essentially the same thing under a different name. If
he was using the Chromium OS then an Ubuntu Linux group is no use as
it works very differently.

You are correct except for one big thing. They are only the same thing if
you ignore licenses. I don't want to belabour the point but licenses DO
matter. Recently Oracle killed off OpenSolaris causing many advocates to
despair, but because it was released as open source, it is being
resurrected. There are countless forks that have given us many great open
source applications. Open source licenses protect our interests from bad
decisions of developers and corporate takeovers.

I have the latest Chromium installed by PPA, so cannot compare with Chrome
features. I suspect that there are differences, but cannot say because they
are different versions. For some reason I always gravitate to Chromium over
Chrome anyway.

I have tried ChromeOS, but find it next to useless. The first time I used it
I wanted to print out something and guess what? You cannot install a
printer.

On the subject of the Chromium/ Chrome browser, Google announced that Chrome
7 will be 60 times faster than Chrome 6 via hardware acceleration. That is
no typo. It gives us something to look forward to.

Slightly confusing to have two browsers with similar names that look
similar !! Have installed Chrome and will get Chromium to see what the
differences are.

Welcome to open source! Linux is all about choice and that often means forks
and spinoffs of just about everything. Because it is open anyone can fork
any project,

It can be confusing and nobody would think less of you for being confused.
It is in this chaos that we have strength. If things were centralised and
proprietary then it would be easy to eliminate us. Linux is like a hydra. If
you cut off one head it grows two more. That is why Microsoft (sorry folks
for using the word) finds Linux so frustrating. It is faced with a
competitor that it can't buy or put out of business and the idea of open
source is anathema to them. So whenever you are feeling confused just smile
and think of Steve Ballmer's blood boiling whenever he thinks of Linux.

Actually I've been an Ubuntu convert for years and get on well with
it, wouldn't think of using anything else as a main OS now <lol> As
for the differences between Google Chrome and Chromium - overall I
think I prefer Chromium and both are certainly faster than Firefox but
overall I still prefer Firefox's look and feel so will stick with it
and await the version 4 release hitting the Ubuntu repositories. Have
tried version 4 beta 5 on WinXP and they've apparently sorted the
memory leak issue at last - certainly releases memory faster when a
tab is closed

For something different, try reKonq which is webkit based Konqueror. I find
it even faster than Chromium.

Sounds like a corrupted upgrade - try removing Chrome and installing
it again after saving the profile data. Chrome is much like Firefox in
that all the settings, passwords, bookmarks etc are stored in a single
folder so saving that then removing / re-installing and copying back
the data in the old profile to the new one puts things back as they
were. If this deletes the button then the corruption is in the profile
so it's a bit more work to get things back to as they should be but
not impossible.

BTW - location of profile is ~/.config/google-chrome/Default and
you'll need to enable viewing of hidden files to see it.

On my computer the bookmark button (a star) moved from the left of the URL bar
to the right where it works normally.
