The other day I downloaded SaveFrom.net Helper but then shortly after I deleted it. The program was deleted from the computer except that the green line with the program name shows as an extension on the bar at the top of the Firefox page. I cannot delete it. If I delete it once it reappears next time I load Firefox. The extension does not show up in add ons and extensions in Tools Firefox. I have read an earlier reply that suggests delete Firefox and reinstall Firefox and that will get rid of it. However, I am not anxious to try that as over time I have already extensions ad add ons and other customisation of Firefox, including all my bookmarks and I don't want to lose these and start again. So here is my question. As the program is deleted and as their extension does not show up in Tools and then adddons, can I assume that the existence of the program name as an extension on one of the title bars at the top of Firefox is just an irritation and that this SaveFrom program cannot in any way add or do anything to my computer? I can then live with it rather than deleting Firefox and starting again. I would be so grateful for your help. Thank you.
