great

good

It didn't captured anything, in the new window only shown a broken image icon. The picture redirects to "data:," and shown nothing, it saved a 0 byte file.

Update 1, reply to developer: yes, I'm using Firefox Develoepr Edition 71.0b4 x64

Fireshot is a gift to the human race. It works brilliantly without any errors at all. Thank you.

Simple to use, works well with no learning curve. Install it and with a modicum of intelligence you have a very adequate screen capture utility. First one I tried, and felt no need to try another.

Had to try another extension for full page screenshots, native firefox and another extension didn't work.

This one did. (Amazon Help Chat popup window with scrollbar)

Fireshot was an extension I used for a very long time, years and years ... maybe 10 years, and even more! I used it on Firefox, Chrome and Opera, Windows 7 and Windows 10 ... And for a long time, it worked very well. It was the first extension I installed each time ... But recently, it starts to save the images no longer in PNG format but as MS-Dos file!

I reported this flaw on the Fireshot forum but the technical support of Fireshot does not believe me (whereas another person had also underlined it for the captures in PDF !!) and thinks that my PC is infected whereas I do regular tests by various anti-malware including the famous Malwarebytes and other no less serious and my PC is totally healthy!

keeps leaving white spots in the middle of two screenshots

[EDIT]: it's in my university transcript so the webpage isn't public.

Does what it says with no troubles or difficulties, even web tables, which no other similar program has been able to do for me and maintain a readable format afterwards. Works great!

It is best
