I updated today to Firefox 5.0 at the urging of Mozilla and---as warned before updating---copy to plain text is not available for this Firefox release. I assume that the developer of this addon will eventually update it but in the meantime because of the kind of work I do I really need either an alternative that will work with Firefox 5.0 or a work around that will allow the addon to work with 5.0. Hopefully nothing too complicated as I am not a power user or tech expert. The availability of Copy to plain text is one of the main reasons I use Firefox 90% of the time on my MacBook Pro running 10.5.8. Thanks in advance for any advice or suggestions.
