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.
