Fóram Tacaíochta Firefox

I am using version `91.5.0esr` of firefox on kali linux (debian). I recently clicked an option that I do not remember. What it does is to put a cursor on the line that I am reading. I do not like it because it is annoying. I want to restore to my default settings

I am using version 91.5.0esr (64-bit). Virtually always, the download status shows as failed. Yet, there were files created by the download. I have even been able to go back literally months in the downloads history, click to retry each download, which is then showed as being successful. I did NOT reload the pages whose content I was trying to download. I realize that a browser tends to have a cache, but surely not that big. I'm guessing that showing the status failed is some type of error.
