I just wanna tip all firefox editors about the addon Menu Wizard.
While editing I use shortcuts to create links (ctrl + k), different headlines (ctrl + 1,2,3,4..), to make the text bold (ctrl + b) etc etc. Updates of firefox however has changed these shortcuts to serve a purpose to the firefox browser instead. As an example the deafult go to search engine shortcut for firefox is (ctrl + k), and the shortcuts (ctrl + 1,2,3..) makes you swap between link 1 and two and three and so forth. SO, when trying to use these shortcurs while edting it will bring you to your search engine or different tabs instead. This complicates editing and you'll have to use the mouse which is more time consuming and troublesome. And this is exactly what Menu Wizard lets you fix.
With Menu Wizard you can change all shortcuts for firefox, or even outright disable them. Which means that (ctrl + k) needs no longer bring you to your deafult search engine. I don't even use this shortcut so I just set it to (ctrl + alt + shift + s). It's easier however to just disable it.
You can also use it to simply set shortcuts that you are more comfortable with. The only purpose I let it serve however was to once again let me use the shortcuts of the PPG-wiki.
