I was browsing news this morning and a popup showed up - You have chosen to download...In the foreground (I had clicked nothing, was hovering over links on Google news and a 2nd tab opened to this web address with all sorts of warnings that a network patch was needed..
As the web address looked illegitimate I soft booted the pages closed

The web is littered with "malvertisements" -- ads which push malware -- and that is the most likely reason to see such a message. (Often these are Flash-based ads, so one way to see fewer of these is to take more control over when sites are allowed to run Flash.)
There are cases, however, in which an infection on your system is responsible, so that is worth checking. I've give suggestions further down in this reply.
There actually is a version 42.0 of Firefox that was released about five weeks ago, but you should be able to get that using the "About Firefox" dialog. Either:
- "3-bar" menu button > "?" icon > About Firefox
- (menu bar) Help > About Firefox
Here's my suggested procedure for tracking down and cleaning up bad add-ons, hijackers, and ad injectors. I know it seems long, but it's not that bad.
(1) Open the Windows Control Panel, Uninstall a Program. After the list loads, click the "Installed on" column heading to group the infections, I mean, additions, by date. This can help in smoking out undisclosed bundle items that snuck in with some software you agreed to install. Be suspicious of everything you do not recognize/remember, as malware often uses important or innocent sounding names to discourage you from removing it. Take out as much trash as possible here.
(2) Open Firefox's Add-ons page using either:
- Ctrl+Shift+a
- "3-bar" menu button (or Tools menu) > Add-ons
- in the Windows "Run" dialog, type or paste
firefox.exe "about:addons"
In the left column, click Plugins. Set nonessential and unrecognized plugins to "Never Activate".
In the left column, click Extensions. Then, if in doubt, disable (or Remove, if possible) unrecognized and unwanted extensions. Bear in mind that all extensions are optional, none come with Firefox, and you can learn more about them by checking their reviews on the Add-ons site.
Often a link will appear above at least one disabled extension to restart Firefox. You can complete your work on the tab and click one of the links as the last step.
(3) You can search for remaining issues with the scanning/cleaning tools listed in our support article: Troubleshoot Firefox issues caused by malware. These on-demand scanners are free and take considerable time to run. If they finish quickly and especially if they require payment, you may have a serious infection. I suggest the specialized forums listed in the article in that case.
Success?
