But I initially didn't spread the word about it as much as for the Chrome one because as previous commenters have noted, the Firefox one is under review for 10 days, and before that it's not a searchable page.
It should not do that. If it does, there's a bug. Can you tell me what page you're looking at?
EDIT: Oh, you mean the actual text inside the "a" tag? Yes, the plugin will change that in its current form. It would be pretty trivial to not have it do that. I will add that next. In the meantime, I don't think the link itself will be affected -- even now, you should be able to click on it and it will go to the right place.
