Diễn đàn hỗ trợ Firefox

I was prompted to install a .js file while on a website unrelated to mozilla organization. I was taking a work call and distracted at the time and was dumb enough to install it before I realized this was not a normal update. Should I uninstall and reinstall firefox? My McAfee blocked the script from "trying to hijack one of [my] apps"

What happened to Firefox's permission's page? There's so few options now. I'm being harassed by websites to give them permission that should be blocked across the entire browser. I'm autistic and sensitive to popups/interruptions/distractions. So most permissions I simply had off for everything, because I don't want to be asked anything. I don't want to confirm anything. I don't want any popup of any type. So I turned everything off and it was good. (except blocking cookies of course)

But now sites are asking me again and there's no way to blanket turn off everything. I see I can press "Ctrl+i" to bring up specific permissions for that site, but that's not good enough. I specifically need permissions blocked for sites I've never visited. Needing to visit the site first completely defeats the purpose.

The permissions listed in the settings isn't all of them. How do I turn off ALL permissions for ALL sites. I can turn on specific permissions when I want them. Essentially, how do I recreate functionality that used to exist but was removed from us for whatever reason.

Also, it's a huge security hole! I'm a senior full stack developer. Asking permissions for a user is a great way to fingerprint them. If I accidentally hit "yes" to a few key permissions, I can be fingerprinted. Another reason I should be able to blanket ban these permissions. I just want my browser to be a browser. These permissions do nothing for me but make the experience worse.

i have a big problem with settings of privacy and security. the problem is i cant edit this option ( Allow Firefox to automatically trust third-party root certificates you install ) and its greyed out . i made everything ( refresh - troubleshoot - uninstall ) and with the first click on singing my account on Firefox and add my restore my add-ons after setting up windows this option become unavailable (greyed out) and cant edit it. i need a solution without going to set up a new windows because its so tiring to set up a new windows to edit this option. please give me a solution its emergency. thanks a lot.

WHAT THE HELL IS THIS???

certificates ImportEnterpriseRoots true

i Active Policy Name Policy Value Certificates ImportEnterpriseRoots true

EXPLAIN PLEASE IF NOT I AM DELETING FIRE FOX

Hello Community - I am Darren Chaker and am inquiring whether Firefox or any other Mozilla browser has a built-in feature for a permanent, secure erasure of browsing data like cache, history, cookies, and site data. Specifically, I'm looking for a function that doesn't just delete the pointers to the data but actively overwrites the data on the storage drive, making it unrecoverable even with forensic tools.

I consult with various people and organizations where who want to only perform a limited function within the browser in lieu of running an entire secure wipe throughout the entire computer using software to conduct a multi-pass wipe, or Cryptographic Erasure where the encryption is destroyed.

Some clients in the legal, financial, and government sectors require data security and sanitization dictate not just best practices, but often legal and regulatory requirements. For these professionals, when data is marked as "deleted," it must be truly and permanently gone. The distinction between a standard file deletion (which often just removes the file system's reference to the data) and a secure wipe is critical.

Currently, I rely on third-party software for these tasks and often recommend solutions like Cryptographic Erasure for sanitizing entire drives by destroying the encryption keys. However, this is for the entire storage device. My question today is focused specifically on the browser level.

When a user selects "Clear Recent History," does Firefox perform any overwriting passes (e.g., a single-pass zeros write), or is it a standard OS-level deletion? If this functionality doesn't exist natively, are there any trusted, Mozilla-vetted extensions that offer this level of secure data sanitization for browsing activity?

Having such a feature natively or through a recommended extension would be an invaluable asset for users who handle sensitive information and require an auditable level of data destruction within their browser environment.

Thank you for your time and any insight you can provide.

Best to everyone here, Darren Chaker

This is one of the more annoying messages Firefox has recently added:

"Your browser is being managed by your organisation."

It is obviously wrong, because it is shown on a private Ubuntu 24.04 computer where I have myself installed Firefox from a tarball installation (Firefox version 142.0.1).

The about:policies page just shows: Homepage: URL "https://start.ubuntu-mate.org/"

  Locked	false
  StartPage	"homepage"

Why does Firefox give such obviously misleading information? All the other articles are not helpful at all either, some are talking about security software, some about malware.

This is an extremely user-unfriendly and confusing message: if security software is to blame, why does Firefox not tell what exactly is restricted? When malware changed something why does Firefox not tell what it changed? What even does the message actually imply, what is prevented what otherwise would work and why? What does the information shown on the about:policies page really tell me?

This is by the way shown when starting Firefox using an EMPTY directory for its profile (so making it use a brand new profile), running from a brand new installation directory extracted from a tar file. So what on earth makes it think it is "managed by my organization"?

There is no extension installed, no policies.json file in the newly created profile, nothing. It looks as if the firefox browser would just arrive with this weird setting/configuration comiled right into it?

Firefox detected a potential security threat and did not continue to player.vimeo.com because this website requires a secure connection.

What can you do about it?

player.vimeo.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it.

If you are on a corporate network or using antivirus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.

In settings, it says Your browser is being managed by your organization. I clicked it and it led me to the policies page. In there it says Policy Name- Certificates, Policy value- ImportEnterpriseRoots and then true. I neither work in an organisation, nor I have any antivirus in my computer. Why is this happening?
