Screengrab is a very simple extension. The biggest thing that people don’t do is notice the addition to their right-click context menu (which is why there’s now an icon too).

Screengrab doesn’t grab Flash or Java.

This should be an issue caused by Sun changing the way they do the Java Plugin for Firefox. They broke stuff and then fixed it again. Before trying anything else, I’d recommend upgrading Java to Version 6u12 which definitely works. 6u11 doesn’t. It broke somewhere in the 6 releases.

It doesn’t work

See: Screengrab doesn’t grab Flash or Java.

I don’t like the Context-menu / Status bar icon. How do I get rid of them?

There are hidden preferences to get rid of them. In about:config change
extensions.screengrab.showInContextMenu
or
extensions.screengrab.showIconInStatusBar
to false.
Please don’t do both, since you won’t be able to use Screengrab if you do!

Can I call it from the command line?

Not yet. I’m working on it.

Screengrab! didn’t save the whole page! I want my money back!

Screengrab isn’t perfect. It’s actually harder than you think to get accurate dimensions for all pages, sometimes the stuff that DOM reports is just plain wrong. If you’ve got a page that doesn’t work, send me the URL and I’ll try to figure out why.

I like the selection tool, but can you make it scroll when it hits the border of the page?

I’ll try…

Jpeg image quality sucks!

It sure does.
Change extensions.screengrab.jpgImageQuality in about:config. Values up to 100 are OK. Beyond that and I think the world will implode.

Selection box over Flash captures pink

Ooops! It seems I made an error and forgot that Java will capture the pink I use to blur out the screen for selections. I’ll try and rectify it. Sorry!
