  • This is a great Addon. So far so good.
    In any YouTube video, I can't find horizontal scroll bar. Also there are two huge horizontal black bar. (What I'm trying to say is that the Addon is unable to adjust according to the video's aspect ratio.
    Again, great Addon.
  • very useful extension :)
  • Love this feature, thanks! Am so glad I discovered it. A bit concerned that Firefox Test Pilot seems to have ended (before I even discovered it). Hope that this excellent add-on does not disappear.
  • Great tool for developers! You can see the desktop and mobile versions of a page in one window.
  • An excellent tool. So useful across so many situations. One of the best is the ability to have my password manager available full time in the sidebar while updating logins. Or simply, anytime I want to keep an important site open and visible while doing other things. Should be a standard feature.
  • Great tool but still need enhancement. Hope that a refresh, back and next page item will be added to the right-click context menu when click on side view.
  • Useful but I can't expand it to more than about 25% of my Mac Powerbook screen. Perhaps I'm doing something wrong.
  • Can't open the second page any more than approximately 30% of the window. Useless.

    WHY is this functionality so freakin' hard to implement!?!?
  • Cool feature that helps me do my job. I can keep my equipment monitoring screen up with my ticket que on one "page".

    I would like to see the ability to have an auto refresh and have both views be equal width (50:50).
  • I can't get BBC iPlayer to play in side view :-(
  • Just perfect
