Thanks. I too use Firefox but rather than Google, I use the 'search as you type' feature on the page.
Still, it's not the same as finding specific words. For example, if I search for 'tom and jerry' I don't want results for 'tom', 'jerry', and/or 'jerry and tom'. It's just more user friendly if I could do it from here directly rather than go to a Google Search page and type the following without the quotes: 'site:aquariumadvice.com/ forum tom and jerry'
Anyway, it's not a big deal.
