Your need is not the same as my need. Personally I do a lot of graphics work so a pixel ruler and a colour picker are absolutely necessary for my day to day use of a browser. Are you happy for your browser to be larger and slower to have these, even if you’ll never use them? Having extensions allows things to be modular and customised to fit the needs of the end user without unnecessary code hogging memory for others.
