I couldn't find it on the Chrome web store, but there were 3 or 4 extensions named Flash Video Downloader, including one that has an icon which looks similar to an add-on that was found to inject ads on websites a few years ago.įVD Video Downloader's last version was 1.32, and it was updated on January 16th, 2019. The developer's name is FV Video, you can take a look at the add-ons's icon in the screenshot. I managed to access a Google cached version of the FVD Video Downloader add-on's page. Jokes aside, I wanted to learn more about the add-on, since I had never used it. Maybe Mozilla doesn't like those initials, eh? The add-on seems to be unrelated to FVD Speed Dial, which coincidentally was also banned by Mozilla. A day later, the FVD Video Downloader has been delisted from Mozilla's add-ons store. Several users raised similar complaints on Mozilla's community portal. A few others chimed in, saying they were facing the same problem, and that removing the add-on solved their issue. Once they disabled the add-on, the browser worked normally. The user eventually figured out the cause of the problem, an add-on called FVD Video Downloader.

They explained that the browser would load web pages, but after a few seconds would redirect them to the questionable site. They were perplexed by the issue, had tried troubleshooting it, from clearing cookies and the cache, and even going to the extent of deleting Firefox's folders. The issue came to light yesterday, when a user reported that Firefox kept redirecting them to a tracking site called 'CDNSURE'. Mozilla bans the FVD Video Downloader extension
