Annoying online ads

This morning I was rushing to finish this big assignment for my Hebrew class and I needed to use an online English to Hebrew dictionary. Well, I know a really good online dictionary for Korean because I have taken lots of classes for that, but since this is my first semester of Hebrew I didn't know where to go. I found several dictionaries, but can I just say that online dictionaries are sometimes not worth it for the plethora of ads that appear on them? Sometimes the ads give me a headache because they're moving and shaking on the screen. Other times they give me knots in my stomach because they're approaching pornography. One dictionary I went to probably had 10 new ads for every word I looked up. The page was really busy and annoying. I didn't use that dictionary for long because of all of the ads. I found out that Google translate doesn't have ads and that was nice.
