This is an invaluable addon! You'll grow to absolutely love it!

I don't use it every day or week -- and, in fact, I might not use it in a month. But when I REALLY NEED it, it is right there waiting for me!

I use it to document the changes I make to client web sites.

I use it to document a forum thread.

I use it to capture web-based documentation that I want to refer to later without having to search for it again.

I use it to capture example sites to show my clients.

I use it to prove to a vendor support forum how their site isn't working properly.

I use it to grab a thread on social media from friends and family that I want to keep in my personal history folder.

I use it to capture web pages with information I want to give my doctor.

I originally installed it because I needed to get the support thread from a vendor site that I needed to email to my attorney. I was worried that they would delete the thread and/or remove my login, so I would not have access to it later.

Since then, I've found lots of reasons to use it.

Like I said, I might not use it on a daily or weekly basis, but when I use it, I LOVE IT!

I have found Fireshot invaluable for taking screen shots. It's easy to use and works flawlessly.

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!
