Don't waste your time on this piece of utterly useless garbage. It captures then produces nothing but a grey screen and with no options to save anything. It is pointless.

very good facility by firefox ,Thank to firefox Team

This feature is absolutely worthless! You cannot take a screen shop and copy the image and paste it. The image does not show up! Sucks!

Dude stop using the system-wide PLAINTEXT PASTE as your screenshot hotkey default! Did you even test this? O_o

La capture ne correspond pas à la zone sélectionnée et je ne vais pas modifier la résolution de mon écran simplement pour effectuer quelques captures.

Capture selected area does not work properly (Fedora Wayland 3200x1800) making addon unusable for me.

Could not extend down to the bottom of the page so significant info was lost negating the effort. Also had trouble figuring how to close and get out of the shot.

何をどうすれば良いのかわからない。普通にクリックしたら保存先が出れば良い。高機能など不要。設定は、JPENかPNGだけ選べれば良い。

It's not much use if it won't capture an entire page for me. Deleting...

Problem Trying to find how you snap a picture of a screen

Can't select areas for capturing, nothing happens. Disappointing.

Title says it all. I click 'Capture selected area' and nothing happens. It shouldn't be this challenging!

This add on won't allow me to save to the folders where I want to save them. My time is valuable and I don't have time or patience the allow an add on to do what it wants to do, and then I have to go behind it and fix it; I refuse to do online storage after having so much of my life hacked in databases; can't this work for those who want to save to the nether world , and for those of us who want to save it to specific files on our computer? Is that really too much to ask?

Have to disable Re-enable when trying , then Doesn't work without faffing. Clips don't go to clipboard and can't paste anywhere else. Quicker to use ScrPrnt and Paint.

Terrible! Not even close to the ease of use and quality of others I've used.

when trying to capture an entire page, the icon just keeps saying "capturing". Capturing the visible part works, though.

I just want to capture a screenshot of the whole webpage. When I selected the option it says that it's capturing but never actually does anything. I need a one click solution and this is not the answer.

I tested Version 3.0.21 (Last Updated: June 22, 2017)
on Firefox 54.0.1 (32 bit) on Windows 8 with 3.5 GB memory.
It installs Ok.
The first page I tested it on was 4chan's Comic and cartoon catalog, not particularly large with small thumbnails.

Problem 1: the addon slowly scrolls down the web page to complete its capture
Problem 2: the browser locked up for a good 5 minutes while the addon was (I guess) composing an editable screencapture in a new tab.
Problem 3: I noticed data was being downloaded from a third party website. Why? Will this work offline like other page savers?
Problem 4: once the capture was complete the cursor changes to a kind of paintbrush and the browser ran very slowly.
Memory use reached 3.5 GB.
I had to control-alt-delete for two minutes to regain my task manager and then able to close the Firefox tab with the editable capture. Browser and computer return to noemal operation.

Clearly something needs fixing here.
Pearl Crescent Page Saver does not do this, it just captures the whole web page and saves it in a file.
I use Pearly Crescent in my other Firefox profiles with no problem.
Pearl Crescent Page Saver does require a restart however, which is why I tried this "Awesome" one.

This might work for some people, but such an initial experience is enough for me to swear never again.

This add-on does not capture the selected area, but results in an enormous horizontal shift.

This addon is corrupted
