Like Firefox 57+ (Quantum), Chrome doesn't let extensions mess with the
chrome of the web browser, and the chrome includes the tabs. Mozilla
(and Google earlier) decided to stop extensions from corrupting or
destabilizing the chrome of their web browsers.

A while ago, there was a Stacked Tabs experimental flag in Chrome where
you could get Chrome to stack tabs rather than shrink them (go to
chrome://flags and search for Stacked Tabs). Google took that away.
That's what happens with these flags: they're considered experimental,
so new ones can show up and old ones disappear.

Google picked the name Chrome for their project's codename and it stuck
when it got released. All web browsers have a chrome. Google just
decided to use that attribute name for their project name.

In the meantime and if you don't like the TMP-alternative extensions to
manage multiple tabs in Chrome (Tab Outliner, OneTab, TooManyTabs, Tab
Glutton or Tab Menu), you could use Shift+Esc to get Chrome's own task
manager from which you can pick which to change its focus. The problem
is Chrome's task manager which mixes together all processes for Chrome,
including those for each tab.
