Entire program suddenly vanished from Firefox 87.0. Nothing in toolbars, not listed in addons list, but this page has a "remove" buton on it still.
Turns out they listed it under "Take.." in the addons list, but the addon begins with "Full.." on the addons.mozilla.org site so you can't find it! They also used the similar "S" for the icon in the toolbar as "HTTPS anywhere" thus making it appear that the icon had vanished. After reinstalling the program there are 2 copies listed in the addons menu, one of which is shown as disabled for some reason. All of this conspired to cause suicidal thoughts.

Advantages
Can capture entire browser window including toolbars, or specific sections.
Converts to PDF instantly, very fast

Disadvantages
Not free.
Why not make it easier to get to the editor window? It's not mentioned in the docs or video.
Needs better documentation including: Videos with a narration
Written documentation needs an update as it refers to an older version

Full page capture only captures visible area not the full page.

its very nice one, but never able to edit in firefox

Created an empty file after taking longer capturing the page then competitors, competitors also don't push another lite version down your throat. I tried this thinking the negative reviewers must be stupid given the majority of positive reviews, I was wrong. Don't make my mistake. Go somewhere else.

This addon no longer works. After several months of use, the plugin scans the page but does not save the screenshot to a file. The problem also occurs with other users, which can be checked on the forum and unexpectedly, buying the pro version helps with this problem. It's over for me

I wanted to rate Fireshot zero stars. They seem to have upgraded it to a paid version. The program on Firefox is no longer functional as far as I know. I'm removing it now, tired of being prompted to buy it, frustrated that it no longer works...

Misleading description, without pro subscription it behaves like default firefox screenshot app.

Offers to capture as PDF with embedded links, but quietly redirects those link to their "buy our software" page. I don't mind folks asking me to buy their freely-provided products, at all. But when a company subverts important functionality without mentioning it, then I simply can't trust them anymore.

The addon doesn't work.
My Screenshots are empty. @susbox: You can try it with this side:

It's November 202: Doesn't work at all. Ping me when they fix it and it works like it used to.

It used to work and now when I use "full page" it cuts things off, like gmail emails. This is frustrating beyond belief.

does not scroll SPAs

Saves Image as MS-DOS ..wtf?!

I finally gave up trying to get a decent image from this add on, uninstalled. Not sure what happened but the saved images aren't readable and are useless. This app used to work once but it's no longer functioning for me. Please fix. Nothing about this inspires me to pay for Pro.

To the developer:
In outlook.com, if you read an email whose bottom part you have to scroll down, using this addon Page Screenshot, it will screenshot the whole VISIBLE AREA but not the NOT VISIBLE PART that is seen only when you scroll down your email.
What I wanted was an addon that would allow me to get a screenshot in jpg or pdf of not only the visible part of the email but especially also the not visible part of the email that is accessible only when you scroll down to see it.

Therefore, I cannot use this addon because it does not do what its title says "Full Web Page Screenshots". The title should be "Screenshot of Only the visible part of the Web Page".

Não funciona, os screenshot ficam cortados pela metade.

스크롤바 있는 전체 페이지 켭쳐할 때 일부가 잘립니다. 제대로 안됩니다.

i tried to take screen shot of my hotmail with full page, but at result many parts were missing in screen shot which was take by fireshot

Doesn't save full web-page, onli visible part. Have tried to select manually full page, but the result was the same - only random visible part of the screen

format pdf non respecté - pdf sous forme d'image

Don't install this extension, it substitutes the links for an link to getfireshot website.
