Flash is unrelated to a web browser? I mean I hate flash as much as the next guy... but how can Flash not be related to a browser?
You want to install Flash for Firefox, it will install Chrome by default.
I did not install flash in FF, and I do not miss a thing. Sometimes there is this warning that not all content could be displayed, but I would not have a clue what functionality is missing.
Chrome has Flash built-in. Shipping Chrome with Flash is inane, because if you install Chrome, you don't need Flash. o_o
Adobe Flash is a browser plugin. Chrome is a browser. How are they unrelated?
If you install Adobe Flash plugin for a different browser, Chrome gets bundled with it. Even if you don't want Chrome.
Chrome doesn't use/work with the Flash browser plugin.
