II must have been onto a dangerous site ??? but anyway I was using another browser and Firefox popped up with messages indicating a virus. As I am a retired head of IT, I closed internet and uninstalled Firefox. I then scanned my Pc with 3 different antivirus packages, My default installed is Sophos. Then there is teh standard MS , plus I installed ESET. All cleared my machine with no issues. I then re- installed Firefox, , it picked up my data and the virus message popped up again. I immediately uninstalled it again. I use REVO to uninstall, which scans for left overs, which I delete as well. Now I HAVE TO ASSUME that Revo is NOT clearing ALL FIREFOX files/data off my PC. Please advise where it is and how I can delete it completely, which is causing the messages to pop up again as soon as i install Firefox.

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.

I am using version 143 for Linux and it is suppose to have improved fingerprinting protection. But when I go to https://coveryourtracks.eff.org i still see a result that says "your browser has a unique fingerprint"

Is there a parameter I should be enabling ?

Hello, Can Firefox not use Google's safe browsing because there are some big conflict of interests. If website owners do not put google's codes in their website, Google will block their website or flag it as deceptive. This may become a large legal issue later. Only once the website user verifies with Google, will this be cleared. I run over 400 websites (all of the same codes) and the websites that I verify with Google were all blocked with a notice that the sites were deceptive. There are no difference in codes with the site that were verified and none were blocked. So I had to upload Google's codes to each website to clear the blockage. There were no phishing, no spamming, and nothing deceptive about any of the websites. The only difference was they were not verified with Google. Thus this forces website owners to put Google's codes on their website which is giving Google way too much control over the internet. I thought firefox was not controlled by any other company such as Google. If I use other browsers such as Microsoft's Edge, none of my website had any issues. Please do not use Google services as that gives too much control to Google. In addition, Google's Captcha is really another obstacle.
