From the top left to the bottom right, there is a small picture in the lower right corner that will change the content of the pictures. When the screenshot is finished, the picture is transformed. When I open the pictures, I find that the content of the small pictures is intercepted.
Expanding the scope of this situation will not occur. This is a minor problem that does not affect use.

There would have been a fifth star if I could configure Fireshot to just save an image without any dialogue when I hit the hotkey.

very good
but don't save full page in some sites
fore example: digikala.com
خیلی برنامه‌ی خوبیست

希望捕捉选定区域时，能截图鼠标悬停出现的字。
