Are the issues I've brought up not worth being frustrated about? Do you think I'm a hypocrite for complaining about the thing that I use?

What would you suggest I do?

I use Chrome sometimes. Firefox is bad in its own way, often emulating the worst of Chrome. Like, at least the Keystone agent is unobtrusive and you don't even know it is there. Last time I checked, Firefox's Updater.app is just as disrespectful to the user, but it is horribly inefficient and clumsy.
