The synonyms load after the google search results page, pushing all the links down a bit. I click, then the page moves down, and I find I have to click again, or it opens the wrong link from the search results. If you're more patient or have a lightning speed connection, this mightn't bother you.
I'm uninstalling it, but if I had an option of only calling up synonyms manually (not for every search) I would keep it.
