Another Firefox’s must have plugin for website designer and frequent blogger is FireShot. This plugin creates web snapshots in many options. The user can choose to capture the whole website or only their visible area (area that you see in your browser, which in this case must be FireFox). FireShot not only creates snapshots for websites but also can upload it into FireShot’s image hosting. This is a one stop solution for bloggers who doesn’t care where their images are stored as long as it is visible as visitors looking at their sites. More information about FireShot and 101 snapshots examples are available in this post.
As I mentioned before, you can choose to take a picture from visible area or the whole website. From there, you can either Upload, Save, Email, Send to Clipboard (same as print screen), or Open in External Editor (MS Paint or Photoshop). And the most useful part is this: Edit.
FireShot also have their own Editing Windows. Saving a lot of times cropping, resizing, drawing or highlighting your snapshots without opening other image external editors. This is a good example for bloggers who wants to create tutorials from website snapshots. The result in Editing Windows can either saved in your computer or directly uploaded in FireShot’s image hosting.
The latest FireShot improvement is the ability to render FLASH animation (as you can see from my example above, the flash section in my website is captured perfectly). Before, it was only plain flash background without the captured animation.
From here you can download examples of website screen shots that I have found from my previous post.
You can find FireShot for FireFox in the FireFox addons page or click here.
Another additional information: This Plugin only applicable to Firefox in Windows…
