Is the "Default dangerous web sites blocker" of Firefox good enough or not?

[kamo_jisan]

Good morning All. Thank you for your access here.
Now I am having a question about URL blocker included Mozilla Firefox.

My antimalware soft is F-secure SAFE now, and it is including a Browsing Protection feature.
This feature is providing web site blocker for protect PC from dangerous web sites.

But this filter is not good. There are many false positives even if major web sites for normally users.
So I turned off only this feature for absent to break the connection to important websites.

Now I am using only "Dangerous web sites blocker" which is included Mozilla Firefox.
I checked the box of "Block dangerous contents" and "Block downloading dangerous files", and "Warn downloading No-need Software" .

Please teach me that is the default blocker included Mozilla Firefox good? or not enough for keeping security?
And if the user turn off anti-malware's site blocker feature, what should the user do?

Windows10 Home, F-secure SAFE, Mozilla Firefox 52.0.1

Thank you!

How does Phishing and Malware Protection work in Firefox?

Phishing and Malware Protection works by checking the sites that you visit against lists of reported phishing, unwanted software and malware sites. These lists are automatically downloaded and updated every 30 minutes or so when the Phishing and Malware Protection features are enabled.

When you download an application file, Firefox checks the site hosting it against a list of sites known to contain "malware". If the site is found on that list, Firefox blocks the file immediately, otherwise it asks Google’s Safe Browsing service if the software is safe by sending it some of the download’s metadata.*

*Windows users: This online check will only be performed in Firefox on Windows for those downloaded files that don’t have a known good publisher. Most of the common and safe software for Windows is signed and so this final check won’t always need to happen.

I recommend to keep Malware and Phishing protection enabled in your browser. If you are not satisfied by Web protection by F-Secure, you can use a Firefox add-on such as Avira Browser Safety to block dangerous websites.

I don't think Firefox has Avira Safety.

I don't think Firefox has Avira Safety.

It does, it just isn't listed in Firefox's add-on store. You have to install it directly from Avira's website.

Mozilla Firefox Anti-Phishing isn't enough in my opinion. You can use uBlock Origin with custom filters or also Netcraft is a good extension.

I remember time ago I used:
Bitdefender TrafficLight - Free Add-on for Secure Web Browsing
It blocked many malicious links ignored by Firefox.

It's a lot better than it used to be, but for much
stricter protection I use AdGuard.

No. Make sure to combo with uBlock Origin (w/ hosts files) or AdGuard for better link protection and advise.

Hello every one. Thank you for your replies and I read all. There are so useful for solving my question.
I understood that browser's URL blocker are having a power for protecting PC, but it is not best for keeping security.
So I will use ublock orign filters with malware filters as default configure.

By the way, I am sorry for my too late reply. And when I will post this site about other questions, problems..., I will be glad you if you join there!
Thank you very much!
