I use it on Microsoft Edge. You still get changes in listed price, but no longer get the number of visits, for some reason. I think it may not have been accurate.
Anyone else finding the Motorwatch extension on FF no longer displays the price history on the search results page? You have to go into the ad to see the details which appears to be a recent change somewhere.
Don’t use that one but on Autotrader what I have noticed is some dealers that have been slowly reducing prices of their stock, all of a sudden put the prices back up to the original listing price.
