Garbage, it says it screenshots the whole website but doesn't do that. Pages with a scroll bar still only get partially screenshotted.

Seems that unless you scroll down to the bottom of the page, it will not capture accurately.
The feeback button does not work. URL never resolves.
Captures with inconsistent results.

Mozilla should be ashamed that a subsidiary trading on the good name of Mozilla is peddling this crap, shame on you.

Worthless.

Useless. It doesnt give the option of where to save and does not put it in 'Desktop' as claimed.

Can only save screenshots in enormously bloated PNG files that are rarely under 2MB in file size!!! This is true even if the image you want to save is 40KB in its native state. Firefox is satanically bad and demonically crippled in the ways functionality in the browser is denied, but this add-on hardly makes things better. It is almost useless for taking screenshots in any quantity.

Fails to capture entire long pages. Only captures part way down and then clips the rest off. This started a couple months ago.

Cannot capture long pages. Only the top of them. So, doesn't fit to the "Whole page cature" annoncement.

第一點. win7與win10使用「擷取網頁特定區域」，經常會讓c:\windows\explorer.exe崩潰，cpu使用25%降不下。請解決bug

第二點. 提供option功能，至少能選擇取消每當存檔時跳出檔案管理員。

Wouldn't load.

Can not find screen shot anywhere, not on my desktop or clipboard. Everything is in a foreign language without explanations. Is it a fake app? Millions of viewers?

Has a maximum page length so doesn't work for what I needed for. Cuts off the image partway when using "get whole page"

全网页截图拼合很差

Never got it to actually function. It goes through the motions -- scrolls the screen, makes a "shutter click" sound, but I never found any images, nor anything on the clipboard.
Also, reported for excessive permissions.

sehr schlecht !
