Work so perfectly.

PROS:
Very productive and stable.
This screen capture add-on (FireShot) let me modify the file name before and set the saving folder path before, then the file name will auto generate and the saving is very fast.

CONS:
(1) if you type screenshot or screen capture or printscreen on the Firefox add-on search box, it cannot show this add-on. You must type screen shot or print screen to search this add-on. I prefer all of the "screen shot" and "screenshot" and "screen capture" and "print screen" and "printscreen" are acceptable to search this(FireShot) add-on at the Firefox add-ons searching box.

(2) There are 2 web stores limitation.
If I want to capture the entire webpages screens at the Firefox add-ons pages(here), I need to use Chrome with this extension.
If I want to capture the entire webpages screens at Chrome web store, I need to use Firefox with this add-on.

Best screenshot Add on in store. Love it

Tout simplement parfait

really best of extensions. makes work easy, support multiple formats. never had any problem using it.

Perfekt!

amazing full page screenshot tool that is high quality and actually works! one caveat is that if the page has side scrolling and vertical scrolling, full page screenshot will not work but that is an easy fix - just zoom out a little to remove the side scrolling!

Instead of spending time on family or rest. You made this amazing plugin that even works for too long pages which firefox's inbuilt screenshot feature can't work! Great plugin. 10/10
