I love firefox but another hugely annoying feature is that hitting the delete key jumps you backwards though the browser history. Who thought that was a good idea? If you think your cursor is in a text field and it isn't then you're in for a nasty surprise when you hit the delete key to edit your text and you navigate away from your current page. What kind of power user is in such a hurry they can't take the two seconds to hit the back button? Who needs to rapidly speed backwards though their history like that. Even if such users do exist, why the delete key? (that's the Backspace key for you PC users)
There are lots of instructions online about how to disable this feature using the config menu. It is easy and anyone can do it if you can follow directions.
- Open a new Firefox tab (apple+T) so you can work in one window and read these direction in the original.
- Type "about:config" into the address field of the new window. Hit return and the config page appears.
- Enter "browser.b" into the "filter" field at the top.
- Click-hold the "Browser.backspace_action" Value column, and choose Modify from the pop-up menu. Type 2 for the new value.
- Click OK.
