I am beyond exhausted with Firefox's issues. Sure, you've cleaned up a lot since Firefox 2, even since the early days of Firefox 3. No more major memory leaks, no more bookmarks getting erased, no more frequent crashes, etc. Good job! Now when the HECK are you going to let us customize your nonsensical, frustrating, sabotaging default key-binds? I can't say how many times I've been screwed over because I can't edit the totally random commands your team thought was clever to add in- randomly closing tabs, going back a page via BACKSPACE and erasing whatever I've written somewhere because inexplicably unlike Opera you refuse to store the data in those cases, and so forth. Look, your design is terrible, and you need to A: Mimic Opera. It's better you in every way, other than compatibility with websites, and everyone knows it. Luckily for you, those compatibility issues are major, so if you can just treat your users with similar respect and consideration, you'd have it all nailed. B: Let us edit the bloody commands. They make as little sense as Window's continued hard-locked use of the Caps Lock key, no one likes the bloody thing, and we should be allowed to disable it. And yes, I'm overly frustrated, I've memory and other cognitive issues and I just lost a long wall of text for the umpteenth time, and because of that first point, I can't simply rewrite it. Stop being mean to the disabled, okay? The internet's vast collection of kitty pictures all want you to stop. True Story. Thanks~~!
