You have a virus. Do not call that number. Download Malwarebytes from www.malwarebytes.com, run a full scan, and remove anything it finds.

Hi jonfry, to add to the first suggestion:

There are numerous scams online involving support subscriptions. You certainly can't trust them to have remote access to your system when they trap you on a page with misinformation about infections and their identity (that number isn't an Apple number).

There are a few common patterns to these annoying pages, and these are some techniques for closing them without having to take drastic measures.

The "key" (ha ha) is the keyboard shortcut for closing the current tab, which is Command+w (or on Windows, Ctrl+w). Try it after each action to see whether it is available yet.

(1) Large alert dialog - lots of text, possible background voice

If you cancel this dialog, it may reappear. After two or three appearances, Firefox should add a checkbox at the bottom of the dialog to stop the site from showing more alerts. Check that box and click OK to block further dialogs.

(2) Authentication dialog - asks for username and password

If you cancel this dialog, the page may reload and immediately show it again. Pressing the Esc key numerous times in a row can cancel the reload as well as the dialog.

(3) Reacting to mouse movement

Some pages have a script that detects when you are moving the mouse pointer up toward the tab bar and takes action to show another dialog, or moves to full screen view to hide the toolbar area. On these pages, the keyboard shortcut is essential.

Hopefully this will let you close problem pages without having to "force quit" Firefox. (I don't recommend using that method because the tab will come back during automatic crash recovery anyway.)

Often these scam pages are promoted through ad networks. As a defensive measure, you could consider using an add-on that is effective at blocking ads, such as:

https://addons.mozilla.org/firefox/addon/ublock-origin/

As with any content blocker, this will cause problems on some sites, so keep an eye on its toolbar button in case you need to make an exception to get a page to load properly.

I use Linux and the site claimed I had a virus on Mac OS. Had to make use of the Esc key while trying to close tab to close it.
