I should say that it is easy to download, upload to server, activate the plugin and then start using. My problem was being able to cut or copy information from OpenOffice.org and then pasting it into the post.
If the cut/paste thing isn't something you have to mess with then everything else is just fine. Just fix the image upload per his instructions & you're good to go.
At work I only did:
$ locate all.js
sudo gedit /usr/lib/mozilla-firefox/greprefs/all.js
on lines 397 & 398 change noAccess to AllAccess:
save the edit - close your browser & wordprocessor. open your browser & wordprocessor and give it a try. again this is for coping text from OpenOffice.org and pasting into Firefox - plus this is on a Linux box.
