I am unable to open certain sites, like Medicare claims, which I've had no trouble with in the past. I get an error message "To protect your security, api.medicare.gov will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window." This happened with another site as well. Please advise.

I have a new Windows 11 PC and have installed Thunderbird (64bit). My current email is via my ISP who have outsourced their email to Gmail - I am using IMAP. This setup is in Outlook 2007 on my old PC. I have setup Thunderbird to obtain all of my current email from the IMAP server at Gmail. This went successfully.

I now wish to move all of my off-line stored emails from this old Outlook installation and also my calendar. When I started the import process on Thunderbird and selected Outlook as a source all I really wanted to do was to find out what Thunderbird would ask for in the way of files containing my data. But, as per other postings that I have found on this site it came up with the "No profile found" .

However Outlook is NOT installed on the Windows 11 computer and nor have I created any pst files or any other files and moved them to the Windows 11 PC. So the 32bit vs 64bit answer does not yet apply to my situation.

So what process should I follow to move my data from the old Outlook 32bit installation on my old Windows 10 PC to the new Thunderbird 64bit setup?

Thanks for any advice

Hello. I'm afraid there has been a data breach from either Firefox or Lockwise.

I have passwords that are used only in local development virtual hosts accessed only from Firefox that are showing up in Google password alerts.

I'm considering changing the location of my HOME calendar. I went to Home Thunderbird Calendar "Changing calendar preferences" in Mozilla support and looked at "Location". It said "Location: This is the location of your calendar. Do not edit this unless you know what you are doing."

I have not had much success in getting more detail. What do I need to know to be sure I know what I am doing.

Every time there is an update, a lot changes and I must spend a lot of time to fix them. This update, as usual, dropped me out of yuotube, so I must sign in. They make me wait 48 hours so they can somehow verify its me. Thanks Mozilla! What else am I yet to discover that I must redo? Also, where can I actually contact Mozilla to bring up this issue? They seem to not want to get feedback from their patrons. Every update (unannounced) has p---ed me o--.

Some times I get a reply to an email I sent out using my hotmail account and Thunderbird says I have one new message but the message does not show up in my inbox. If I login to my hotmail account through Microsoft it show it in my in box. What is the problem and how do I fix it?

I suppose the best place to start is when/where I think this problem started. Approx three to four weeks ago my thunderbird program stopped downloading emails from my server (Spectrum/RR). I say Approx because the problem sort of sneaked up on me without me realizing it was there.

I was using W7 and my hard drive was pretty much full and I was constantly getting messages that my email could not be downloaded due to lack of space. I started deleting stored emails and emptying the trash, which sort of kept me up and running for the past couple weeks. All this time my Gmail account continued to work as it should, downloading every email that was sent to me, but the Spectrum/RR account was spotty at best.

So today I fired up a new W11 computer for the first time. One of the first programs I installed was Thunderbird. When I attempted to set up an account using Spectrum/RR the process failed. I typed in all of the correct information, Name, Email, and Password but the account will not finalize. Instead, I continue to get the same message that the Configuration, Username or Password is incorrect.

I have since successfully logged into my Spectrum/RR web mail, so I know the username and password I am using is correct. I have also talked with Spectrum Technical support, and they have verified that what I am using to log in is correct.

I hope I didn't ramble on to much and someone can help me !

I've tried restarting and reinstalling Thunderbird but no change in this blockage since Tuesday. I am running Windows 11 Pro and Thunderbird 128.1.0esr (64-bit). Downloading chunks of email from Comcast and trying to import them doesn't work. Please advise as I am stuck. I will check your answers on Comcast server as I can not read them directly.

I'm getting a message the following message each time I try to send an email:

"Sending of the message Failed.

Unable to authenticate to Outgoing server (SMTP) smtp.googlemail.com. Please check the password and verify the "Authentication method" in Account Settings | Outgoing server (SMTP)'.

Under SMTP Server I see the following: Description:Google Mail Server Name: smtp.googlemail.com Port: 465 Connection security: SSL/TLS Authentication method: OAuth2

How can I get my outgoing email working again? It worked yesterday. Thanks, Carla

When I first opened Thunderbird (just a few weeks ago), I noticed that some Calendar Tasks were already set up by Thunderbird. (My standalone calendar is Efficient Reminder).

But I don't see options for REMINDERS - popups (preferably) and/or sounds. (The purpose of a calendar for me is to be reminded to do things.)

I searched for options in Thunderbird, and I looked on the information here, but can't find anything.

If I can I select a sound and/or popup to REMIND me, where can I find the option to set it?

Hello! I recently got the update to Thunderbird 128 on my PopOS laptop via sudo apt update/upgrade. I don't know what the previous version was. Since the update, Thunderbird will spike my CPU to 120 - 140% (per command-line "top") if I have an interaction with it (e.g. reading and then deleting an email that was received) after the program has been sitting idle for several minutes. After a few minutes of loud fans, things calm down again so I presume Thunderbird is doing some sort of maintenance routine that completes successfully.

I do not have the global search index thing turned on. I did not change the default mailbox db idle time. I do have rather large mailboxes that are synced via SMTP, from three different providers. There are dozens of folders (not hundreds) containing thousands if messages (but not tens of thousands). Hopefully that gives an idea of scale .. I don't have a massive overload of untended email history but I do have a quantity of historical emails that the system has to deal with.

I followed the excellent directions online to obtain a profile during one of these high-cpu sessions. It is available at https://share.firefox.dev/4dAmyAz

Please let me know if there is anything further I can do to help diagnose this issue, such as generating more specific profiles. The high-cpu state is a pretty common occurrance now.

I have determined that the cause of these crashes is hardware acceleration being enabled, I can share more details if desired. It ran in troubleshoot mode then I added extensions one at a time, none of them crashed Firefox. upon turning on the hardware acceleration it crashes upon opening a PDF

This is the message I get trying to log on to my email. Please help! Using chrome I can sign in to my email. Thank you!

Over the past few weeks my emails are constantly freezing up when I open Thunderbird. It hangs up and I have to close the program and then restart, sometimes having to do this several times. It will then be normal for a short while, and start doing it again. I am running Windows 7 on my PC, I have the latest Thunderbird downloaded up until two weeks ago I never had this issue. I have not installed any new software either. I did think maybe it was CCleaner or Advanced Systemcare so I uninstalled those two programs yet the problem is still ongoing. Its quite frustrating and I can't figure out why its happening or what a potential fix for it. Thank you to those who respond.
