I also know that I'm in the minority, and that maybe the size of my cohort is too small to add yet another thing to check during regression testing.

But I'm still mad about it :) Firefox always seemed like the browser for people who want to configure weird things, or extend it in all sorts of crazy ways. More and more it's becoming a me-too browser, and the only reason I'm sticking with it is out of a sense of duty to fight a Chrome monoculture.

The comments on the bug report point out that the new behavior makes Firefox on Linux different from other Linux applications, including some browsers. The devs said they want Firefox to be consistent across platforms, whereas the Linux users want Firefox to be consistent with the rest of their system.

The new behavior is also different from the behavior of text boxes rendered by Firefox.
