Well, as a user you have the option of using another browser. Though, admittedly, with 1 gig of RAM I can't think of any decent one that wont give you problems after a few hours of browsing -- maybe chrome?
As a web developer, I wish they'd concentrate on making a browser that lets you change the line-height of a button/input element. Such a simple change, yet the problem has been around since 2006, if I recall correctly.
It's not a simple change, because sites actually rely on not being able to _decrease_ the line-height. I tried allowing sites to change the line-height and had to back that out because of sites breaking. You can read the whole sordid story at https://bugzilla.mozilla.org/show_bug.cgi?id=349259
Note that the change to allow changing line-height specifically on <button> did stick, and will ship in the next Firefox release in 3 weeks or so.
My opinion is that relying on line-height being unable to decrease a height of an element is a really bad idea and the owners of those sites should just be forced to fix it. Of course, I understand how from your perspective making a change that breaks a site like youtube (and probably a decent percentage of sites in general) is probably not an acceptable solution.
Oh well, I personally only needed line-heights on button elements, so the mentioned change will actually solve my UI problems. Thank you.
Yeah, if I could force site owners to fix their sites my job would be way easier. ;)
As it is, if no browser allows it, then sites will depend on not being able to do it, and any browser that does allow it will be perceived as buggy (adding to the resistance to fix the problem on the site's end).
