CopyPlainText is one of my favorite Firefox add-ons because it can filter out all of the formatting and leave the text alone. It is an amazing tool especially when editing non plain-text editor such as Microsoft Word etc.
After I upgrade to Firefox 3.5, I found that this add-on is no longer available. Therefore, I created my work-around version here. No functionality has been changed, except it works fine in Firefox 3.5+ 🙂
…And if you want to use any Firefox Add-on on Firefox 3.5+ but it is not available, feel free to let me know! Don’t forget to include the link of the apps.
