My Yahoo email for the most part is fine. But, I am having a lot of difficulty when I type replies to emails I have. When I have to correct something in my text, I keep getting the blue lines that cover the existing text and want to cancel some of the text I have already done. As soon as I move the cursor to another part of the text, the blue line covering will cancel everything there after and I don't want that to happen. Not sure why this is occurring. I didn't have this peculiar problem before hand. It's just typing replies to emails has become a real pain, and I'm not sure why? Can anyone help with my Yahoo email? Frankly, trying to contact Yahoo itself is really not a option as they usually don't reply to problems. So, I hope Firefox may have a have a solution? Thank you.
