Remove “Urgent Firefox Update” ads (Improved Guide)

removal by Olivia Morelli - - | Type: Adware

Should you trust “Urgent Firefox Update” ads and update your browser?

If your Internet browsing suddenly gets interrupted by an update request, don’t hurry to download it, because it might be the Urgent Firefox Update virus that you are having business with. This virus shows up on Mozilla Firefox browsers, though it is not yet known whether Macs and Windows OS are equally susceptible to the infection. What we are sure of, is the fact that this virus only pretends to be a software update in order to get the users to download suspicious executables or javascript files labeled “firefox-patch.” The tactics chosen to deliver this potential scam make it pretty believable. Once the browser is infected, the virus creates a virtual layer on which it displays the well-recognizable Firefox update logo, with an additional “URGENT FIREFOX UPDATE — Download Now” message underneath. It then opens a pop-up with download permission request which also obstructs the user from browsing the web normally. Something you would expect a normal browser update would do? Well, not quite. If such update ever appears on your browser, there is one way to test its reliability. Just look at the URL of the page you are on. If it’s not the official Firefox website, but suspicious domains like,,, or, do NOT allow any downloads. Also, make sure you close your browser and run an antivirus scan immediately to find and remove Urgent Firefox Update malware from your PC. You can obviously do all the elimination manually. Nevertheless, we recommend sticking to reputable antivirus tools, such as Reimage Reimage Cleaner Intego.

Picture of "Urgent Firefox Update" ads

The problem with Urgent Firefox Update hijack is that this update scam is just a small part of a much larger picture that a sneaky adware is responsible for. As a result, apart from these notifications you will probably witness generally increased scale of online advertising and, possibly, not on your Firefox browser only. Google Chrome, Internet Explorer or Microsoft Edge browsers may start deploying ads urging you to buy goods, visit certain websites, fill in online surveys, etc. If the adware is especially malicious, it may also get involved in tech support scam business. Thus, you should be extremely careful once you start noticing any unusual or suspicious ads. For more gullible users, we suggest refraining from using the browser completely while this adware is on the computer. While you are off the network, you can take care of the Urgent Firefox Update removal. We strongly suggest attending to this virus as soon as possible, because its prolonged stay on the computer usually turns out to be harmful. In other words, infectious Urgent Firefox Update ads may bring malware, viruses and Trojans to your PC.

How do these ads find their way into computers?

In its essence, Urgent Firefox Update program is very similar to other adware-type infections such as “Java Software Critical Update” or “Update Windows 7 Drivers” which use fake update notifications to trick users into downloading potential malware. All of these programs are PUPs, so they are all distributed using the same misleading “bundling” method. Bundling allows spreading several programs at a time placing them in a single software package. This can be used for a good cause, like promoting less popular software or adding extra tools in addition to some larger software. Nevertheless, this method is now largely abused by the malwartisers, so if you found Urgent Firefox Update installed on your computer, it most likely ended up there due to malicious bundling. Such practice of spreading adware around is tricky but can be outsmarted. You should begin with software downloading. Do not obtain software from unreputable sources and try to stay away from unsafe file sharing domains. Secondly, once you download some program or a software package, scan it with anti-malware or anti-spyware utility before proceeding with the installation. Finally, check whether the software you have downloaded is not bundled with potentially unwanted programs and cancel their installation if you notice any.

Is there a way to remove Urgent Firefox Update ads?

If you never had any experience with adware, getting rid of Urgent Firefox Update virus may seem like an impossible mission. Luckily, it isn’t so. In fact, this malware can be easily removed using automatic antivirus tools. Experts suggest that the software you use for the Urgent Firefox Update removal should be legally obtained and updated. Otherwise, the elimination might get tricky or fail entirely. Also, make sure you do a little research before obtaining any virus-fighting tool, in order to choose the best option.

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
