When I downloaded installed portable Fox (from Mozilla Site) to thumb drive I was presented with two options from an advertiser in which I could choose by checking one of two box's (which I didn't check) continued with process which stated I will need to enter my email when the install completes. That never came up and I suspect it was because I elected not to choose an advertiser.

After rebooting the installing PC (after I installed Portable Fox on thumb) from which I downloaded portable fox to a persistent boot nagware pops up from all - any signed in user account on the PC.

Was this foxes intent to allow the advertiser to this with out warning of nagware install and choice to opt out and discontinue the install process?

I have windows & pro I had to go to the process running and then click process properties / security and disallow it access to all users to stop the pop up. But the point is Mozilla should have been 100% clear about the nagware install even if under certain conditions it installs (being I suspect if you don't choose one of the advertisers box's and continue with install.

hello augustborn, mozilla doesn't develop or offer any portable version of firefox to download, so you couldn't have got that file from directly.

if a third party is misusing the firefox brand to offer a modified adware-infested version of the browser for download, please report them at
