The team built a giant letter “e” and snuck it on the lawn of { -brand-name-netscape } headquarters. The { -brand-name-netscape } team promptly knocked the giant “e” over and <a href="{ $dino }">put their own { -brand-name-mozilla } dinosaur mascot on top of it</a>.

There are a lot of reasons you might want to know the exact hex color code of a specific color on a web page — maybe you build webpages or are a graphic designer. The eyedropper tool, in the desktop version of { -brand-name-firefox }, lets you find exact hex color codes just by hovering over any color you see on a web page. A click will copy that color value to your clipboard.

Social networks know a lot about you. Plus, they’re able to track you beyond their platforms with their Share and Like buttons despite Tracking Protection — even if you don’t have an account. The <a href="{ $container }">{ -brand-name-facebook-container }</a> for { -brand-name-firefox } makes sure that { -brand-name-facebook } and { -brand-name-instagram } can’t do this so easily, which again reduces the probability of seeing misinformation via ads and promoted content significantly.

Ultimately, both misinformation and disinformation can be harmful. It’s not only that people will believe incorrect information, false information costs the global economy a lot of money and can threaten democracy and efficient governance. And it’s difficult to stop because false news spreads significantly faster, deeper and more broadly than news that is correct.

No. Your IP address is only associated with one location unless you are using a VPN (we will get more into that later). When you are at your home and connecting to the internet you pay for, you are using one. However, if you check your email at home in the morning, then scan the news at a local coffee shop while waiting for your coffee, and then work from an office, you will have used different IP addresses at each location.

This is a bit of a tricky question — the answer is both yes and no. More than one device can share the same external (public) IP address, but each device will have its own local (private) IP address. For example, your ISP (internet service provider) sets your home up with one external IP address. Since your router is what actually connects to the internet, the IP address is assigned to your router. Your router then assigns a local IP address to each device that is connected to the internet at a time. The external IP address is what is shared with the outside world. Your local IP address is not shared outside of your private home network.

We now have version 6 IP addresses, which have 128 bits per address. Unfortunately, version 4 and version 6 can’t talk to each other directly, so people are going to need version 4 addresses for a long time.

A secure web proxy works for tasks that you might do only in your browser. This can amount to a lot of activity like shopping, paying bills, logging into social media and reading emails. A secure web proxy serves as an intermediary between your browser and the internet. Your web browsing data will pass through a secure tunnel to the internet directly from your browser, masking your IP address, so the web server you are contacting doesn’t know exactly where you are in the world. And that makes you harder to track and target.

The most important thing to consider when picking either a VPN or a proxy service is choosing a trustworthy company. Be sure you understand the terms you’re agreeing to. Many claim to be great and focused on privacy, but a large number of them fall short on their promise. Not all proxy and VPN services are secure and private. Some <a href="{ $cnet }">will</a> <a href="{ $pcmag }">log</a> your online activities so they can sell your data and information to marketing firms themselves. Other services will try to convince you to install malware on your devices.

Virtual private networks (VPNs) and secure web proxies are solutions for better privacy and security online, but it can be confusing to figure out which one is right for you. Here’s a look at how these services protect you and how to choose the best option for when you’re online.

A VPN provider typically offers a number of connection gateways in different global locations, which allows you to use an IP address from a locale different from your own. That way, the place you’re connecting to sees the VPN’s IP, not your actual IP address, as the source of your traffic. <a href="{ $mozvpn }">{ -brand-name-mozilla-vpn }</a> routes your traffic through a secure server and lets you choose a location from more than { $countries } countries.

It’s very hard to find a trustworthy VPN. VPNs are intended to protect users while they’re online, but not all VPNs are equal in the service they deliver. When shopping around for a VPN service, be sure you understand the terms you’re agreeing to. Many claim to be great and focused on privacy, but a large number of them fall short on their promise. Some VPNs will log your online activities so they can sell your data and information to marketing firms themselves. Other VPNs will try to convince you to install malware on your devices.

Have you ever connected to a hotspot called something like <em>C0MCAST-WiFi-77th-St</em> or <em>Verizon3-Hotspot-Baltimore</em>? Looks legit, right? Not so fast. In reality, anyone can set up a phony public WiFi with a legitimate sounding name to lure people to use it. Connecting to any unknown WiFi makes you an easy target for creeps and criminals who want to access your device to steal private information, install malware or worse. <a href="{ $mozvpn }">{ -brand-name-mozilla-vpn }</a> can boost your security any time you’re connected to a public WiFi by blocking unknown entities from seeing private data that travels from your phone or laptop. This goes for connecting to WiFi networks at coffee shops, stores, doctor’s offices and so on.
