periodically, about one a day or more, I have my browser redirected to the following site:

https://othooalibris.com/5963093335741/d44a6507c6c7c2bc3ca4163c41d99d90/249fbc8ac6aa911a52dc12aaaaec293f.html

The page displays the following message: Critical Firefox update, download now.

Is this a valid Mozilla Firefox download? It is harmful?

Thank you for your help,

Sincerely, Matthew

If you get a pop-up message asking to update Firefox or plugins or scanning for malware then such a message is likely a scam and you should never respond to such an alert to avoid getting infected with malware.

  • Only update Firefox via "Help > About" or by downloading and installing Firefox from the Mozilla server and never via a pop-up or link on a web page.
  • plugins should only be updated via the plugin itself or by visiting the home page of the plugin.

Hi    !
Good for you be on the alert for these fake updates   ! Firefox will always update from within the browser and not from a random webpage. Scammers have been using this tactic, trying to get users to download and infect their computer. Hard to get rid off, as they will change their URL on a daily basis. You could consider an ad-blocking add-on like :
https://addons.mozilla.org/en-US/firefox/addon/ublock-origin/?src=ss
This might keep you from getting these fake updates   (and other stuff like it)   again.
