I tested the process and was able to create this first try:
It works like this:
- Click on the extension in the Extension listing next to the OmniBar.
- Select which type of screenshot you want to take.
- After taking the screenshot, an editor window opens that looks like the one below.
- Once you have finished you will be given options on how to share or save on the active page.
*** Note: this extension does add branding to each screenshot. For some that might be a deal killer. You can contribute to the app to have that removed. I wondered if you were to change the size of the original screenshot, would that branding be "less in the way" of the image. This was my modification:
I am still not sure I like the way the branding of the extension appears and clutters the screenshot. I was only able to get a little more space and it is less imposing. For a quick screenshot that does not need to have a polished look, this might be a helpful extension.
