There is no way to use these extensions. And, as usual, Firefox offers no support whatsoever. Back to Safari.

免费就可用，截图方便，但保存需要多次操作，给点建议：再简化就好了，如果截图支持直接自动选中边框，这样就不会出现左右不对齐

Limited usability in the free version. Surprised by all the stars.

it works as advertised. I did see the comment about PDF problem. I wish markup hero was available.

super easy to use with the shortcut and works well. Easy to save as png, pdf, or copy (this is particularly useful for pasting things into documents without having to save the screenshot)

artificially limits screenshot size and makes you pay for a so-called "pro" version

i've only been using the free version but it never disappoints, awesome for capturing long websites that don't fit on the screen. love the option to save as png or pdf, and greatly appreciate that it's not a spyware app!

So handy and quick to use Absolutely love this.

Great plugin, works right of the box, quick and straightforward
