Loved this add on until they introduced the AdWare into it Rated 1 out of 5 stars

Yes, it's true, they bolted an extremely annoying, cheesy piece of adWare into this add-on, and it was one of my absolute favorites. It watches your browsing and if it sees that you are looking at a PRODUCT then it makes a popup to suggest alternatives (oh, so useful.) It is garbage. I never review with anger like this. What is worse is that the text in the description of the add on claims that it is possible to turn off this "feature." it's not. there is no off switch. OK, so I say goodbye to a decent Extension. Well, I will see if it halts the adware if i Disable the app, and then I can re-enable it if I want screen shots.
Let's be honest: Perhaps this is the only way these guys can make a living with this otherwise excellent app.

This review is for a previous version of the add-on (2.3.7). 

Yep, it does full-page screenshots right,. Rated 5 out of 5 stars

15 seconds after installing, this had made an excellent full-page screenshot for me and I was on my way.

I have used 3 other tools to make full-page screenshots, and each one either had its functionality disappear after version numbers increased, or choked on Flash content, etc.

This app does fine capturing the Flash content. And it has what looks like a very smooth annotate-and-upload-to-the-cloud feature, which I could possibly wind up using -- I use skitch for that now but using this would allow me to not have to hop to another app.

NOTE: one issue -- though it snapshotted the flash content OK, there was indeed one piece of the page it did not capture -- namely, an embedded Youtube video embed that we had on our page. I used image editing software to transplant back in. Can you fix that next version? thx. I paid the suggested $4, definitely worth it for me. good stuff.

This review is for a previous version of the add-on (2.3).
