The text on that page is way too small, especially the source code :/

And it breaks the split-view Greasemonkey script, too. Alas, plunged into the dark ages of two days ago.

It took me some time to stop feeling shame for hitting Ctrl-+ on pages with tiny text, but I've come to terms with it. I'm also a fan of View->Page Style->No Style, which I discovered only after writing a Greasemonkey script to do the same thing.

I knew about Web Developer's Ctrl+Shift+S (disable all styles), but I had no idea about that built-in style disabling. I just tried it on Gmail and it was quite...interesting...

I did not notice anything on Safari.
