It works as intended!

I don't care that it doesn't work on YouTube/LinkedIn, chat messages and posts are not what it's for!

Doesn't work for YouTube which is the only reason I want it.

Probably works great, just it will not work for twitter. I understand twitter is a timeline based site, but when you scroll your twitter likes, leave, don't like a new tweet, then come back, the extension gets confused. Has not been updated in 3 years so I can't blame it.

Very useful on long pages.

Only con I can think of is that we need to enable it manually for each page. It won't automatically do it for all pages.

As user I find this extension very useful when I read long articles poorly layedout on one single page or on web pages that reload multiple automatically. Ad developer I find it useful in conjunction with a live server and the autosave in the IDE, it keeps the position focused on the part that I'm working on at any automatic reload ;)

its too easy to remember the browsered location,good add ons ! if add a short key that will be better.
