New add-ons

Did a tidy of my Firefox add-ons list. Lots just don't seem to be keeping up with Firefox updates, so I've switched to something else.

New ones are:

• text/plain - converts plain text links to real links
• Tab Mix Plus - previous tab add-on flunked so switched
• ReminderFox - neat ping for when you get lost in time online etc
• gTranslate - as I often check foreign stories, this is very useful

Some more on my list are doomed to deletion if they don't catch up soon ...
