Microsoft Edge Strengthens Security by Blocking Sideloaded Extensions

[johny899]

You won't believe this! Microsoft Edge is getting even better. Soon, the browser will automatically block malicious extensions that are sideloaded. If you have no idea what that means, or why it matters, let’s look into the details.

Why this matters​

Extensions are like little upgrades for your browsers. You install them for matters like ad blocking, saving passwords, or changing the way web pages look. The catch? Some extensions are not downloaded through the store, and other people sideload extensions and install them manually.

Sideloading is great for developers and testers, but it could also allow attackers into your browser. A questionable extension could slip in, track what you are doing, or take over your browser. Yikes! This is why Microsoft wants to protect you from the bad stuff!

What’s Changing​

Microsoft has announced that Edge will soon be able to detect and disable malicious-sideloaded extensions. Basically, Edge will block extensions that look potentially harmful, for extensions installed outside of the store.

What we know so far:

• This will rollout in November.
• Microsoft still hasn't said how they will determine if an extension is bad.
• Regular users who stick to only download extensions from the store likely won't see any impact.

It is like having another lock on your door, you might never need it but it's nice to know it is there.

Other Microsoft Security Upgrades​

Edge is gaining the upgrade. Microsoft has added some security features lately:

• Better protection for developer accounts and extension updates.
• A tool to warn you if an extension is slowing your browser's performance.
• An AI now blocks tech support scam pop-ups in real time.
• HTTPS-First Mode, which makes connections more secure.
• In Edge v.140, a memory-saving tool will automatically discard sleeping tabs.

Pretty decent list, right?

What This Means To You​

So, what's it mean for us?

• You're probably safe if you are just sticking to the official Edge Add-ons store.
• If you sideload extensions for testing or for custom tools, there's a chance something could become blocked.
• Mistakes happen, and a good extension could be flagged, but I assume Microsoft will find some sort of way to address this.

Final Thoughts​

I genuinely think this is a good idea. The bad extensions are sneaky, and most people don't know the risk until after the fact. Will it eliminate every bad extension? Probably not, but it's another barrier that enhances the overall security of using Edge.

So, if you really enjoy installing third-party add-ons keep your eyes peeled for this in November. Note, if one of your sideloaded extensions goes away you will know why.
