Hello. I am not familiar with this end to end encryption that Facebook now does for Messenger but now when I try to use Video Calling/Chat it tells me it is not supported by my browser, Firefox. I have never had any problems with it before. Is there a fix? Thanks

I have the strangest problem. If Firefox is closed and I do a speedtest in another browser, download a file, or do other internet activity I'm getting about 200-250Mbps d/l and 100Mbps upload. As soon as I open Firefox, whether I load a page or not, the upload speed stays the same, however the download speed drops to about 25-50 Mbps. This only happens on one PC, the upload isn't affected, and resolves itself as soon as Firefox is closed. Here's what I have done without any change in this behaviour;

• Rebooted
• ipconfig /release /renew /flushdns
• Removed and reinstalled the network adapter
• Enabled, disabled windows auto tuning and tested (slower disabled)
• Updated Windows
• Refreshed Firefox
• Uninstalled Firefox, deleted remaining folders from Appdata (Local, Low, Roaming) as well as the program file directories and "Mozilla" registry entries. Restarted and reinstalled. Issue immediately resumed when Firefox was open.

Also when connected to a VPN Firefox download speed increases to about 60Mbps and is consistent across other software. If I split tunnel another browser outside the VPN, it is still stuck at 60Mbps. If I close Firefox the speed increases.

This makes absolutely no sense to me, so I'm hoping someone can shed some light on this - but it does seem to be something Firefox is doing.

Thanks for any help anyone can provide.

This feature has suddenly appeared and I absolutely detest it! I don't need it, don't like it, don't want it! I have searched everywhere on how to disable it. PLEASE tell me there is an option to do that.

I have Thunderbird 128.3.3esr installed on my PC desktop. The Beta app for Android says to go to Settings on the desktop app and select "Export to Mobile" to get the QR code. However, I cannot find "Export to Mobile" even using the search box. Where is it?

Also, once my accounts are in the Beta phone app, are they synced with the desktop app?

Got this error message on recent update and now Firefox doesn't work at all. Platform Version '131.0.3' is not compatible with minversion >= 131.0.2 maxversion <= 131.0.2

Nord keeps telling me that Mozilla Thunderbird Version 128.0.1 Severity level : High. Exploiting this vulnerability is relatively straight forward for attackers. They may gain unauthorized access to your data or cause system disruptions. Risk mitigation is needed. This message was also for the latest 115 version. Then I updated to 128 and it has the same problem

A new version of the "List All Tabs" appeared on my toolbar today, shown on the left and hovered over in the attached screenshot (ignore the Malwarebytes extension icon). The old icon for this button was a chevron with approximately the same functionality. I was able to remove the old icon, but I'm unable to find a way to remove this one. Here is what I've tried so far:

• Like the old one, the Customize Toolbar feature is unable to remove it since it is grayed out.
• For a while, I was able to remove the old icon by going to about:config and setting browser.tabs.tabmanager.enabled to false. This solution does not work for the current and some recent versions of the button.
• I attempted to create a userChrome.css file (following all the steps according to this this website) and added the following string: #alltabs-button { display: none !important; }

None of these attempted fixes have removed the button following a browser restart. Is there a way to remove it? I have no need of a button that shows me what tabs I have open when I can simply look at my toolbar.

Hey there, long story short - nowadays it's crucial to support those who WFH, and most people use G Suit for company work. I personally have a few daily calls via Google Meet and having the TAB sharing feature available is highly appreciated. I know this was requested a lot, but this is a real dealbreaker for many people.

What are your thoughts on this? Maybe it's somewhere in the roadmap already? Thanks!

Microsoft tell me that I must use OAuth2 for my accounts, else I'll be locked out.

Server is imap-mail.outlook.com. If I select OAuth2, then I can't receive emails unless I reset back to Normal Password.

I'm also supposed to set my SMTP server (smtp-mail.outlook.com) to OAuth2, but this isn't an option on the drop down list.

Help, please!

Norton 360 updated last night and now Thunderbird isn't working.

I tried logging in to Thunderbird but it kept saying my certificate was wrong and refusing to check my emails. I tried to click "add exception" but it didn't help.

It also kept saying its own homepage was a security risk and blocking it.

I figured it was Nortons new update, but have no idea how to fix it. I turned off Nortons Email Protection, which didn't help. So I uninstalled Thunderbird and reinstalled it.

But now its saying it cannot login to the outlook server when I try to add an email account. I know the information is correct, all I can guess is that Norton is blocking it somehow?

Any idea on how I can fix this?

Good morning Windows 10, TB 115.11.0 32 bit. Multiple email accounts, some gmail, others like sfr, lol and free. All accounts use POP. All working before weekend, shut down the PC. Monday morning, opened Windows, all seems there except TB which has a screen with an Account Setup tab inviting me to set up an existing email address. Close that tab and the attached screen image appears, open tabs blank, no accounts pane on the left, no emails, no local folders. Nuffin. Restart TB and Windows, twice, still Nuffin. Look in Profiles, yes, under Mail all profiles appear to be present and the correct size. Going to gmail’s on line email system shews account open and receiving email normally. I had a problem a month ago after a TB update when all accounts were present but no emails were displayed. I changed the password to 0auth and recovered my emails. That took three days to resolve and I lost a business client through the delay in responding. Today I must file several court documents or I shall be in deep poo. Any suggestions how to recover the left hand accounts pane and see the accounts and folders will earn my undying gratitude.

I am using Windows 11 and FF 127.02. I have read the lag issue with Youtube was suppose to be corrected with FF 127.02 but it is not. I have been using FF for many years now an love it. It is my understanding that it is the ad blockers causing the slow down. Do you have an estimated date when this will be resolved. I have tried every trick included running it in diagnostic mode or trouble shooting mode. Nothing seems to work. Not even a refresh.

Thanks

Everytime I load Firefox the bookmarks sidebar is not shown.

Navigating thus View => Sidebar => Bookmarks I can bring it up. It will stay visible for the whole of my browser session. However, after I've closed this session and started another. the bookmark sidebar is missing again.

How can I make the bookmarks sidr be available all the time?

FF 127.0.2 OS Windows 11 Pro v 24H2 Build(26100.994).

Since the penultimate and now the last current update to version 127.0.2 (64Bit), the button (tile with the + sign) to add new shortcuts is no longer available. How can new shortcuts be added now?

As of 2024 06 20 there are many websites that I cannot login anymore one being Facebook with this message:Update Your Browser You’re using a web browser that isn’t supported by Facebook.

From the article "Microsoft OAuth Authentication and Thunderbird in 2024" there is a screenshot showing a OAuth2 option for the SMTP server setting with STARTTLS connection security. It does not appear for me. There are only the five options, as shown in the screenshot. How do enable the option to be available in the drop-down list or set it?

The available options are:

No Authentication Normal Password Encrypted Password Kerberos / GSSAPI NTLM

I am on Thunderbird version 115.12.1 (64-bit), Windows 11, version 23H2, build 22631.3737

I have a Google Calendar, in which I manage My Tasks. I can't see my existing tasks in Thunderbird, and I can't add new tasks to the Google Calendar. New Task in Thunderbird is greyed out and the field next to it has the writing: "Please select a calendar that supports tasks".

I have seen that many had the same issue and understood that it is linked to how My Tasks in Google Calendar itself works. Is there really no workaround whatsoever?

If not, how can I manage tasks and share them with someone else (who uses Google Calendar or Apple Calendar, but does not use Thunderbird)?

Thanks in advance for your replies!
