The DM BBCode FireFox extension is a generic extension that works with any site that uses BBCode (most forums everywhere and many blogs). This extension adds an entry into your context menu when you right click on stuff to make the relevant BBCode for you.
How to use:
• Right click on images, links, selected text, anywhere on a website to access the "Copy to clipboard" BBCode menu
• Right click inside a text box to apply BBCode to the selected text
• Right click on images to upload them and get BBCode generated for them
• Right click in a text box to upload an image and insert the BBCode in a couple of clicks
• Customise your FireFox toolbar to add the "Upload Image" button

Then you just need to past it into your favourite forum, which naturally would be the DirtMind forum
The extension integrates into the free (not even any ads!) DirtMind image host so that you can upload pics from your own computer and automatically generate BBCode for them. You can also upload pics from any other website just by right clicking on them!
Once an image is uploaded to DirtMind, you can also add captions to make your own lolcats etc.

Also when you're in a textarea (such as when posting on a forum) the extension adds new right click menu that applies BBCode such as quote, url, img tags etc. to the current selection.
