If you don't want that app or don't know what it is, deny permission for it to be installed.

The request is part of a Firefox update, when I click on install I get the request to allow the app, the update will not install unless I allow the app which makes me suspect it is not legitimate. Firefox will not run without installing the update. I deleted Firefox, downloaded it and installed it, I then again get the update request. Am happy to allow it if I can confirm it is OK

HI, Firefox does not offer other programs to download with updates. It may look real but it is not and is in your system.

Please use more than 1 scanner as each uses diff tech :

No version of of desktop Firefox for Windows, Mac OSX, or Linux from mozilla.org like www.mozilla.org/firefox/all/ comes with this or by a internal Firefox update from Mozilla.

I loaded the lonlingdom.cool in the Location (address) bar and there was a message

Sorry, this product is currently only available for Google Chrome.

I have run a full scan with Kaspersky internet security and run Malwarebytes Neither found any problems.

lonlingdom.cool is not show in addons extensions.

I reinstalled Firefox from a download dated 24/08/2017 which gives me version 61.0.1 (64-bit).

All now (seems )to be OK

Many thanks to all who gave suggestions.
