How can I set up a VPN on my Android phone

Moderator note: This question has been moved from the Firefox Desktop forum to the Firefox for Android forum.

Free youtube downloader wants my age from Firefox to download popular music videos. I am logged in to FireFox and Free YouTube downloader identifies FireFox as my default browser.

This is really an error for Free YouTube Downloader to correct, but many FireFox users must have solved this already. Any advice?

Thank you!

When I last tried to buy with Google stored debit card from my bank the transaction was blocked by the presence of a four-month old phone number. I have updated several weeks ago to my current telephone number and address. Yet the new number is not there, instead the old number is not helping me.

I keep getting notifications, supposedly from Mozilla and/or Microsoft on lower right of my screen, telling me the system is infected. How do i determine if these messages are valid, or a scam ? Turned computer off and back on--messages keep popping up.

The way to opt out is to go on the following website and opt out. However, only 3 out of the 51 companies could opt out on Firefox. It claims that the browser setting is prevent it from opting out. https://optout.networkadvertising.org/?c=1

I have recently discovered that Firefox is constantly sending data at around 3KBytes/S to a variety of Cloudflare servers.

What is the data that is being sent and why is this happening?

This has started to occur in one of the last updates to Firefox.

Currently running 151.0.4 (64-bit) on Windows

Does this constitute a privacy violation, what is the data that is being sent?

Hello Hello sometimes websites redirect away from the requierd adress to something wrong.

Samples: https://www.writelatex.com/read/sjchktdtqwcm This redirects to https://www.overleaf.com/

https://plus.google.com/u/0/110765980098077923527/posts/JpSZhceCDXE this redirects to https://workspaceupdates.googleblog.com/2023/04/new-community-features-for-google-chat-and-an-update-currents%20.html

How can i force such sites to stay at the link-address ans open that properly instead of even trying to redirect?

Best regards Maxi

I have accounts that will not work because they cannot access my location, My computer says all access is allowed, so is there something in Firefox that blocks my location?

I have all options enabled to save addresses and credit cards.

When I try to manually add a credit card, hitting the Save button does nothing.

When I use a credit card on a site, Firefox prompts me to save the card, I confirm that I want to save it, yet it isn't saved.

Microsoft Outlook Client emails are legally valid in a court of law, but Thunderbird emails are not. Can we start taking baby steps towards making Thunderbird emails a little more viable in legal applications?

While I do not understand these things in the depth required, can we start taking baby steps towards achieving legal validity of emails downloaded from Thunderbird?

I am presenting below a conversation that I had with chat GPT regarding this matter for the help of anyone who wishes to take this up.

Chat GPT:

QUESTION 1: 1. As per my limited knowledge, Outlook client emails are legally valid because the header cannot be edited. This however, is not true of Thunderbird emails. Do I understand correctly? 2. What are the challenges in making Thunderbird header not user editable, so that Thunderbird emails also have the same benefit?

Chat GPT: Your question touches on email authenticity and legal validity—especially in regulated or evidence-sensitive contexts. Let's break it down:

Is it true that Outlook headers are immutable and Thunderbird’s are not?

Partially True — but needs clarification.

Email headers in both Outlook and Thunderbird

Can be viewed by recipients, but cannot be edited after the email has been sent. Only during composition can certain headers (like `From`, `Reply-To`) be changed, depending on the setup.

What you cannot change post-sending:

After an email is sent (from any client), the core SMTP headers (`Date`, `From`, `Message-ID`, etc.) are locked. These are generated by the sending server and cryptographically traceable via server logs or DKIM.

Outlook’s extra layer:

Outlook integrates closely with Microsoft Exchange, which stores server-side logs, message tracking, and non-editable audit trails (e.g., via journaling). That’s what gives Outlook/Exchange emails more evidentiary credibility, not just the client itself. In contrast, Thunderbird usually connects via standard IMAP/SMTP, without server-side logging, unless used with a corporate mail server like Postfix + Dovecot + journaling.

In Summary: Table Feature Outlook (w/ Exchange) Thunderbird Headers editable during composition Yes (some fields) Yes (same) Headers editable after sending No No Built-in server-side logging Yes (Exchange) No (unless configured) Strong evidentiary trail Common in enterprise Requires external setup

What are the challenges in making Thunderbird headers non-editable during composition?

The challenge lies not in technical impossibility, but in the design philosophy of Thunderbird:

a. Open Source & User Control

Thunderbird is open source, so users can customize or even extend the client to manipulate headers (via extensions or config changes). This is powerful for advanced users, but not ideal in regulated or high-trust environments.

b. Lack of Server-Side Enforcement

Thunderbird relies on whatever SMTP/IMAP servers it connects to. Unless the server enforces policies (like DKIM signing, DMARC, or header filtering), client settings are only soft limits.

c. Missing Native Audit Features

Outlook/Exchange logs metadata like when a message was sent, delivered, read, etc. Thunderbird lacks that unless paired with enterprise-grade backends. How Could Thunderbird Improve Legal Trustworthiness?

1. Header Locking During Composition

  	Disable or grey out fields like `From`, `Date`, `Message-ID`.
  	Possible via extension, but not enforced by default.

2. Enforced Server-Side Signing (e.g., DKIM)

  	Ensure outgoing mail is cryptographically signed to verify integrity.
  	Requires a properly configured mail server, not just Thunderbird.

3. Journaling or BCC Archiving

  	Auto-BCC all sent mail to a tamper-proof archival system.
  	Thunderbird can do this via rules or server configuration.

4. Extension or Mode for “Forensic Compliance”

  	Custom Thunderbird modes that restrict editing headers, disable extensions, log actions, etc.

Final Thoughts

You're correct in understanding that Thunderbird offers less baked-in legal reliability than Outlook + Exchange. But this isn’t due to insecure design—rather, it's due to Thunderbird’s flexibility and lack of tight server integration. Thunderbird can be made trustworthy with the right server configuration (DKIM, archiving) and possibly some custom add-ons.

If you’re looking to build or propose a “forensic-grade” Thunderbird environment, I can help design one with proper technical constraints and audit trails. Let me know!

QUESTION 2: My legal Counsel has told me that emails downloaded from the Gmail server into the outlook client are legally valid. So even without Microsoft Exchange and all the other server side logging, Outlook emails are legally viable. Chat GPT

Yes — your legal counsel is broadly correct, and here’s the nuanced explanation:

Emails Downloaded via Outlook (from Gmail) Can Be Legally Valid

Even without Microsoft Exchange, emails downloaded into Outlook (say via IMAP or POP from Gmail) can still be legally viable evidence, because:

1. Outlook stores email in a tamper-evident format

Outlook saves emails in `.pst` or `.ost` files. These files have a structured, proprietary binary format that is hard to tamper with without detection. Courts often accept these files (with chain of custody) as original records.

2. Outlook preserves server headers

Even when connected to Gmail, Outlook does not modify or fake headers. It shows server-signed headers (like `Message-ID`, `Date`, etc.) exactly as received. These headers can be verified independently against:

Gmail’s “Show Original” → raw headers DKIM/DMARC authentication

3. Integrity from Gmail itself

Gmail assigns unique `Message-ID`s and signs outgoing mail with DKIM. DKIM proves the message has not been tampered with since it left Google’s servers. So even if Outlook is the client, the source of trust is Gmail + DKIM, not just the software.

In Legal Contexts

4. What courts typically require is:

 A copy of the original message as received (headers intact)
 Some form of chain of custody (who had access, how was it stored)
 Optionally, confirmation from the mail server logs (if challenged)
 Outlook is often used in corporate/legal environments because:

It does not let users easily forge full headers The data format is harder to manipulate Legal teams and forensic experts are familiar with `.pst` files

So even without Exchange, emails received and stored in Outlook are trusted, provided:

The full headers are intact The `.pst` or `.ost` file has not been tampered with

5. How This Differs from Thunderbird

Thunderbird also preserves headers and stores messages locally — but: Table: Aspect Outlook Thunderbird Storage format `.pst`/`.ost` (proprietary) `.mbox` or plain text Header immutability Enforced by format Editable via text file (with effort) Forensic familiarity High (in legal circles) Moderate Tamper-evidence Strong (binary format) Weak (editable with text editors)

So Thunderbird messages can technically be altered more easily after download, especially if stored in `.mbox` or `.eml` formats. That’s why they are viewed with more caution in legal settings.

Conclusion

Yes — emails downloaded into Outlook, even from Gmail, are generally accepted as legally valid, provided the headers are intact and the file has not been manipulated. Outlook's storage format and market reputation contribute to its legal trustworthiness — even without Exchange.

If you want to achieve similar legal credibility with Thunderbird, the focus should be on:

Enforcing DKIM-signing (from Gmail, already done) Locking down `.eml` or `.mbox` file access Possibly archiving in tamper-evident formats

Let me know if you’d like a workflow to export Thunderbird emails into a legally robust format similar to `.pst`.
