Explain when you get this. When you open the browser, surfing the web . . . .

Go to the Mozilla Add-ons Web Page {web Link} (There’s a lot of good stuff here) and search for a good ad blocker.

I suddenly get this every time I go to Earthlink Webmail on Firefox. I have to close the browser in order to get rid of it. So I cant use Webmail now. Seems more than an ad. I think it's malware. I have added no add-ons recently. FredMcD said

Let's set aside the possibility that Earthlink's site is infected. They might display ads from popular ad networks and some of those ads may show scam pages. This is why Fred suggested trying an ad blocker, 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.

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 Ctrl+w (or on Mac, Cmd+w). Try it after each action to see whether it is available yet.

(1) Large alert dialog (lots of text)

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 "kill" Firefox in the Windows Task Manager. (I don't recommend using that method because the tab will come back during automatic crash recovery anyway.)

Hello jimlau,

In addition to the above, please see :

https://malwaretips.com/blogs/remove-dear-mozilla-firefox-user/

May I suggest to do this :

Go to the Firefox menu (≡) => Preferences => Add-ons => Extensions and remove anything that looks unfamiliar or suspicious.

Do the same in Windows Control Panel.

Next step : run malwarescans - further information can be found in this article :

Run most or all of the listed malware scanners. They all work differently - what one program doesn't pick up, the other might.

I will look into this more. The pop up blocker is taking care of it, tho I'd rather not go that route.

Btw, I close the tab, not the whole browser, as I always have multiple tabs open. Just weird it started after I've made no changes. Maybe Earthlink is having an issue. Will try to see.

Thanks.

You can also check the connection settings.

• Options/Preferences -> General -> Network: Connection -> Settings

If you do not need to use a proxy to connect to internet then try to select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.

See "Firefox connection settings":
