Mixed Emotions Rated 2 out of 5 stars
I have given this extension a pretty good work out for several weeks on three email accounts, using Windows Vista. The more I use it the less favorable I feel about it.
Pros: *It does a reasonable job of removing most spam.
*It installs easily (but doesn't uninstall as easily).
Cons: *With three accounts, email retrieval gets slower and slower the more it is used.
*You can't deactivate it. Email stops working completely, unless you go in and reset all the ports, etc.
*The learning curve, for both the program and I, is extremely long and I am not an amateur.
*The spam goes to the trash, but the trash is often not emptied on exit as it is set to do.
*There always seems to be some emails that are obviously junk, but you still have to click on the icon to get rid of it.
Summary: The extension is on the right track and almost works. But you still have to keep a close eye on things. If you look at the parent site, the developers have put a lot of work into it and continue to do so. For now it appears Thunderbird's built in filters will suit my purpose.
