As creator of retroonline.net. We recently noticed Firefox have limited value size in IDB which Chrome and Edge do not have. This limitation prevents big games running on Firefox despite Firefox has the best performance on WASM. Will there be a proper way to change this limitation or plan to remove it?

Stolen laptop .Thunderbird had saved all my accounts passwords . I had no master password. Accounts were synced with my desktop .Now I installed Primary Password and, changed all my accounts passwords . Can the thief still access my accounts on stolen laptop. I backed up my profiles. Can messages on laptop be deleted . If I delete all messages from my desktop, will all messages also be deleted from stolen laptop if thief access thunderbird

I'm trying to send an OpenPGP-encrypted email from a Linux Mint machine using msmtp, relaying through the smtp server, to another Linux machine, to myself, running Thunderbird (with the sender's (my) imported private key already loaded and working in Thunderbird).

The encrypted test message is composed manually as a file (email.eml) and sent using msmtp from the command line. The email successfully passes through the SMTP relay, is received and decrypted by Thunderbird (so the OpenPGP decryption part works that much I know ... ), but the plain text content is not rendered properly and the email is displayed blank, no plain text as expected. Thunderbird has decrypted the message, but it’s not being displayed or rendered.

This makes me think the issue lies in the structure or MIME headers/parts of the .eml file itself — specifically how the encrypted message body is wrapped. This is not something I'm entirely familiar with, and even less so with what Thunderbird expects for a PGP encrypted message...

I suspect the issue is due to incorrect MIME formatting or missing headers (Content-Type, Content-Transfer-Encoding, Charset, or boundaries etc.) needed for Thunderbird to correctly render the decrypted body into plain text once it receives it. Since I’m assembling the .eml manually (and eventually by a script whej I get to it), I may be overlooking certain structural requirements that typical mail clients (say Thunderbird or similar) or gpg front-ends (like mutt, mailx ...) would handle automatically.

My questions are: Is there a correct MIME structure or format expected by Thunderbird for OpenPGP-encrypted emails ? Is this documented anywhere specifically for Thunderbird ? Or, are there publicly available examples or specs that describe how such an email should be structured (e.g., RFCs or working .eml templates)?

Is there a known way to validate or "lint" .eml files for OpenPGP compatibility ? That would be nice ;-)

As I said the internals or MIME formatting is not my thing usually. Any pointers to Th.B. documentation, sample files, or tools that help with .eml structure validation would be grately appreciated.

Thanks in advance, cheers MM

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?

Hello:

I'm not certain if this question comes under Firefox or not:

How do you stop a specific computer software program-app pop-up notification (popping out from the lower right corner of your computer)?

As an example, I have a utility program, IOBIT Malware System Care that pops-up various notifications such as "update notice," "renew," "discount sale" or whatever notice or ads that is 'pushed'.

-I went to my Windows 11 list of installed app "notifications" and this program is not listed. -I tried contacting tech support but they haven't responded. -I went to Firefox 'Settings' -> Privacy & Security->Permissions and then I opened up 'Exceptions' to see if I can block something. It wants me to put in a specific website. The issue is not a website but coming within a software / app program.

So how and where do I stop a "pushed' notification? I assume it's coming in via my browser / Firefox?

Thank you in advance,

Steven

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`.

Dear Team,

When my Client device installs From Firefox 102.7.0 ESR to Firefox 128.7.0 from SCCM. (The case is First install the Version 102.7.0 then save the Bookmarks and then uninstall. Second Install the 128.7.0 then check the bookmarks)

user profile Bookmarks are not mapped in Firefox. When I check C:\Users\Tests\AppData\Roaming\Mozilla\Firefox\Profiles I can see the xxxx.defaultesr

I don't understand why the bookmarks are not linked in Firefox. Can you please help? I would be thankful to you if you could share me the .bat script

Thank you

Trying to use Thunderbird after break of some years and want to use Proton Mail. Every time I try to set it up I get message 'the certificate 127.0.0.1does not come from trusted source'. Previous experience of Thunderbird was that there were frequent issues like this arising.

I have been using Thunderbird forr many years and earthlink is my server. After doing many emails this morning Thunderbird stopped sending emails and showed a Security Certificate alert problem for smtpauth.earthlink.net:587 that i had nor seen before. I tried to over ride but could not. I can still receive emails. dan_doherty@earthlink.net

I've been using Thunderbird for my earthlink.net accounts for years. Now I'm getting an Error that "Peer's Certificate issuer is not recognized. My earthlink.net settings have not changed. Help.

Subject: OCSP Must-Staple Behavior Observations in Firefox (Including iOS Platform)

Dear Firefox Team,

We have been conducting tests involving certificates with the OCSP Must-Staple extension and would like to share several observations regarding Firefox’s behavior across different platforms:

General Compliance with Must-Staple: On most platforms, Firefox correctly enforces the Must-Staple extension. That is, if a certificate includes the Must-Staple flag and the web server fails to provide a stapled OCSP response, the connection is appropriately terminated.

Unexpected Behavior on iOS: However, we have observed that Firefox on iOS does not appear to enforce this requirement consistently. Even when the server does not provide a stapled OCSP response, the browser still establishes the TLS connection. We are unsure whether this is due to platform limitations or an implementation inconsistency.

Redundant OCSP Requests Despite Stapling: Additionally, we found that Firefox still initiates an OCSP request even when a valid stapled response has already been provided by the server. This behavior not only degrades performance but may also introduce privacy concerns, it contrary to the original privacy and efficiency goals of OCSP Stapling.
