Easy to use. Best Addon to save PDF pages.

I'm using the free version on a 2015 iMAC with Mojave. It generally provides a result that accurately reproduces how the page looks in the browser. It is better at doing this than the native print-to-pdf capabilities of the MacOS/Firefox combo. It's at least as good as any other plugin of this kind that I have tried, on any browser on this same computer. The plug-in has sustained this level of functionality for several years -- I think I first started using it in 2016. Best feature other than the fact that it works is that you can customize file names, including using sequential numbers within filenames (e.g.: [today'sdate]+[domainname]+[n], then [today'sdate]+[domainname]+[n+1]). This allows you to skip the Save-As dialog (using another preference option) most of the time. Every once in a while I run into a page with weird scripting or multimedia elements which this plug-in can't reproduce accurately. Usually I'll find that the same page causes problems with all the tools available to me; but sometimes one of the others will work better. No tool works on everything. Very long scrolling pages (e.g., several months of a Facebook newsfeed) can take a long time, may temporarily use a lot of RAM, and Firefox may throw up error messages which I ignore. Usually I can keep doing other things, and the end result is usually a good reproduction of that very long page. Every once in a while I ask too much and have to abort through firefox, or restart firefox.

GREAT APP!!! Simple, easy to use and useful. Great options that are easy to understand and navigate.

This is my goto screenshot extension, I've used it for years and does the job perfectly without any fuss.

Recently, about the new update version. It pops up the "Please wait: creating..." in the center of the PC screen is annoying. I suggest it can
popup in the center of the Firefox windows that is saving the screenshots and not appear at the center of the LCD screen. Because I have moved the firefox to the right side of the screen to use. And the left side of the screen is doing only video stream recording.

Does exactly what you need it to

Useful. A few quirks, but who am I to complain about free stuff? It does what it says it will do.

Excellent! Exactly what I needed: Full page Screenshots of websites.

An absolute MUST HAVE for the more "serious" or "experienced" browser user. A+ Product no question!

Don't pay for pro version. Was working but the pro options have disappeared/not working. PDFs are no longer split into pages, and only captures 1 scrolling box of a whole web page with 2 scrolling boxes. Dev does not respond to emails. "Support site" is a shambles. If you are lucky you won't get a message saying "this message cannot be posted". If you are lucky your message will be posted but you will never see it nor will anyone else because there is no sort by date or filter on the site. Will update if I receive a reply.

Love this add-on couldn't get by without it. I use it daily. Thanks for such a great tool!

Practically perfect all-page screengrabber

FireShot could just as well have been called "SureShot". Works every time, except in certain protected pages as explained in the instructions. There are very few of those, and there are workarounds. For those of you familiar with Safari's "Export to PDF" feature, it is about the same, from the user point of view. Love this extension. Try it. You will probably like it.
