I was excited for about five minutes into I went into Yahoo Classic email and found it removed the sidebar there. Who knows how many other left sidebars it may remove. I'll have to find another script, but gave this three stars because it worked as intended, for Google at least.

please only include google
please do not modify every leftnav

yes i was glad i didn't have to do this myself but ever since that sidebar started to show up i wanted to get rid of it. only suggestion would be to limit it to google as many other sites do use a #leftnav id...

Good answer to stupid change.

Change it so it won't run on *.

Make the @include on only Google domains.

simply removes the new google "Everything" sidebar on the left. 5 stars
