I cannot receive mail from my Outlook.com account in Thunderbird. This does not appear to be a Thunderbird configuration problem.

Thunderbird 159.0 on Windows. IMAP: outlook.office365.com, port 993, SSL/TLS, OAuth2, username = full address SMTP: smtp.office365.com, port 587, STARTTLS, OAuth2, username = full address

The Microsoft sign-in window completes successfully and an OAuth2 token is issued and stored. Using the same token: 1. SMTP AUTH XOAUTH2 succeeds: 235 2.7.0 Authentication successful 2. IMAP AUTHENTICATE XOAUTH2 fails: NO User is authenticated but not connected. 3. POP3 AUTH XOAUTH2 fails with an authentication/protocol error

I also reproduced the IMAP failure with a raw IMAP connection, outside Thunderbird. A brand-new Thunderbird profile still fails for this Outlook.com account; a Gmail account in the same profile works normally. Thunderbird is up to date.

Outlook on the web works. IMAP is enabled in Outlook.com settings (toggled off and back on). The same IMAP failure happens on two different networks.

I have already contacted official Outlook.com support. They said IMAP is outside their scope as long as Outlook.com works in the browser, and directed me to Feedback Hub.

Is there any Thunderbird-side workaround, or any known Outlook.com IMAP OAuth2 bind issue and recommended next step?

Request to Make Firefox VPN Available to Users in Iran

Dear Firefox Team,

I am writing to express my concern about the recent unavailability of Firefox's built-in VPN service in Iran and to kindly request that you consider making this feature accessible to users in the country.

I had been using Firefox's built-in VPN regularly, and it was an extremely valuable tool for me. Unfortunately, I recently discovered that Iran is not included in the list of supported countries, and the service is no longer available to me.

Internet access in Iran is subject to significant restrictions. Many international websites and online services are either blocked by the authorities or restrict access to users connecting from Iranian IP addresses. As a result, accessing independent information, educational resources, professional platforms, and many essential online services can be extremely difficult.

For users like me, Firefox's built-in VPN was more than just a convenient browser feature. It provided an opportunity to access the open internet, overcome geographical restrictions, and stay connected to the global digital community.

I understand that service availability may depend on technical, legal, or regulatory considerations. However, I sincerely hope Mozilla will reconsider its regional availability policy and explore ways to make this feature accessible to people in Iran, subject to applicable requirements.

Mozilla has long been associated with an open, accessible, and user-centered internet. Making this service available to users who face substantial barriers to accessing information would be a meaningful reflection of those values.

I would appreciate it if you could forward this request to the relevant team and let me know whether there are any plans to support users in Iran in the future.

Thank you for your time and for your continued efforts to keep the internet open and accessible to everyone.

Kind regards,

Built-in VPN stuck on "Get started" after successful sign-in (Firefox 159.0.1, Iran)

Hi,

I'm trying to use Firefox's built-in VPN, but I can't turn it on.

Details: - Firefox version: 159.0.1 (64-bit), up to date - OS: Windows 11 - Location: Iraq - Mozilla account: signed in successfully (I see "Signed in successfully!" on accounts.firefox.com)

Problem: After signing in, the VPN panel in the toolbar still shows "Try Firefox's built-in VPN" with a "Get started" button. When I click it, I'm asked to sign in again and end up in a loop. I can never turn the VPN on.

What I checked: - about:policies shows "The Enterprise Policies service is inactive." - I manually set browser.ipProtection.enabled to true in about:config (the VPN button only appeared after this).

I noticed that Iran is not on the list of supported regions in your help article "Unable to find the built-in VPN in Firefox." Is this the reason it doesn't work for me? If so, are there plans to make the built-in VPN available in Iraq? If not, could you tell me what else might be causing this loop?

Thank you.

Y do you use too much space in the windows pc? Too much ram usage for simple browser activity? Like 10tabs take almost 2.5gb ram space and most of the tabs have simple non dynamic pages open..

I want to use Firefox instead of google chrome because chrome is too too much of a space occupier.. but you also seem to be equivalent to it... So thinking of unistalling u and switching to brave browser.. brave is very nice a lightweight than you , it seems so in the system monitor application

Hi I'm having this issue with the built-in vpn for firefox where it keeps sending me back to the "Get Started" page every time I sign in. The vpn was working just fine last until I closed the browser and opened it again a few minutes later. I asked Chatgpt for help but couldn't fix the issue and it sent me here. There are no policies listed on the about policies page, the remote improvements setting is enabled and there are no vpn holdback studies appearing in the about:studies page. Also, the issue persists even in troubleshoot mode. Any ideas how to fix this problem? Thanks in advance
