I don't like update

dschettek, are you referring to the new New Tab page? If so, then you can at present revert back to the previous version: # type or paste "about:config" into the address bar and press enter. # press the button to accept the risk. # type or paste "browser.newtabpage.activity-stream.nova.enabled" into the search field. # when the result appears, press the toggle button on its right hand side to toggle it from true to false. For more information on the new New Tab page, see here: https://connect.mozilla.org/t5/discussions/firefox-151-introduces-a-fresh-new-look-for-home-amp-new-tab/td-p/125715 The developers are listening to feedback at this link, and changes will be made soon.
