Anyone know how I can get my mouse back up to normal speed?

3 days ago, I left it sitting here on the bed as I went downstairs to get something to eat and one of my shoes caught the wire and pulled it off the bed onto the carpeted floor, as has happened a dozen or so times before. When I came back up 2 hours later, all of a sudden, it would hardly do anything I wanted it do, as far as moving the pointer! Normally, . one sideways swipe with it will take it all the way across the screen but now, sometimes I have to do that 5 or 10 times to get it to move that far!! The settings on it have been as fast as it can possibly go for years! I tried resetting it to as slow as it can go, clicking on "apply"and then resetting it on high speed and that didn't work. I even did a go back on the entire computer and the only thing that changed is that, now, when I watch videos on YT I get a number of commercials before, during and after the videos, which I never had before!! It also told me that Fiirefox, that I'd been using for quite a few years was no longer any good and I had to delete it and reinstall it!! (It worked perfectly fine before I did the go back!!) So, now, if I set up a number of videos in a row to watch, it no longer jumps right over to the next one in line automatically and I have to click on each one to play it, nearly all the time, instead of showing a listing of other videos I might want to see down the right side of the screen, it shows them stacked up across the bottom of the screen!!

I DO believe the problem is solved! The mouse pad was one of those smooth, slick deals, as soon as I flipped it over and started using the rough rubber side, the mouse worked great, again!! So, I just need one of those cloth-covered mouse pads. I've got a bunch of them, I'm just not sure where.
