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

Lo trovo utilissimo, senza bug o crash, mi serve per svago e per lavoro.

Just what the title says. The most awesome add-on firefox has. Try it out now. You won't regret it.

I have been using Fireshot for some time and it has become very unreliable. This beats it every day of the week. The only (slight) problem is that it is not entirely clear where to save the screenshots to. Other than that, brilliant.

good operability。

Very good!And Easy to work with Awesome&more/THANKS!
And very usefull for the Future! For simple and Fast Dokumetations !

Good nice..

截图功能很强大

много всего делает!

Not sure why it doesn't seem to work for others. This works great in ALL modes for me. I was forced to switch from Nimbus after downloading/installing FF 55.0.1.2, and I'm glad I found this "webextension". Thanks.

Does what it promises to do and does it with ease. Would not mind less marketing noise on the page though.

good

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

Awesome Screenshot 3.0.21
Firefox 55.0.1
Windows 7 Home Premium x64 SP-1

Takes forever to capture (using this Mozilla page for testing a capture). If I change focus to another window, even just Notepad, the capture is aborted in Firefox. I'd wait for over 12 minutes for a page capture while resisting to change focus to other windows and still the add-on failed: just a constant worthless "Capturing" message. Great, a super-slow add-on that won't continue the capture if focus changes to another window while waiting for their capture to do anything. Other capture programs (e.g., Nimbus Screenshot and Pearl Crescent Page Saver) are immediate when I capture a page (but those others have a short remaining lifetime since they are not Web Extension add-ons). This add-on is unusable (in my setup as noted above).

Sehr gut für meine Zwecke

Super einfach soll jeder Browser haben.

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.

Génial, car je viens seulement de comprendre comment l'utiliser pour par ex. imprimer qu'une partie d'une page avec des camemberts de ma comptabilité ! SUPER. Merci Diigo.Inc.

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.

great

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