I am not able to access my emails in Yahoo Mail. Can't even send emails. Tried accessing Yahoo Mail using Chrome and did not encounter any accessibility problems.

I chose Firefox specifically because I disliked the overly rounded design trends in other browsers like Chrome. The subtle, smaller rounded corners in Firefox v144 were perfect - they looked professional and clean.

Please consider reverting to the smaller border radius from version 144.

When T-Bird sends a message with an in-content photo, is that photo compressed to save space and transmission time?

I converted from Eudora. Eudora would compress in-content photos to save space and transmission time.

If T-Bird performs a similar action, is that compressed file saved somewhere?

Every time I accidentally close Firefox I lose all my saved groups on reopening. I can see they are still there but cannot see how to open them. They are such a great innovation. Please make it easier to restore them from previous sessions. Going through a search history and restoring them one by one is hugely time consuming when they are already there and just inaccessible. btw, I tried using scrounger (via troubleshooting) but the "Save List" is greyed out.

Running on Mac OS 15.6.1

Hello

One morning about a week ago I woke up and opened my computer. Some update has probably been installed, and all the tab groups that I have diligently organized and saved - disappeared!

The tabs disappeared and all the sites saved within them disappeared also.

Please your help

Chase website now requires Mozilla Firefox update 128 or higher to access accounts. My version says my version (115.30) is latest update. Do I need to find a different browser or is there a solution? I am using Windows 7 Pro desktop. Thank you.

I'm trying to sync Thunderbird Calendar with iCloud. Every time I enter the password generated by iCloud, Thunderbird indicates that the credentials are incorrect. Any suggestions?

Sorry for the long=winded message but I figured it would save time to explain the steps from the beginning.

I've been using Thunderbird as an OSB for my archived messages from Apple Mail. In that scenario I create a .mbox file of all messages I want to save from a particular year and then import that into Thunderbird into a local folder with the year as the folder name. The version of Thunderbird where I was doing that is 115.10.1

I started testing Thunderbird version 139.0.2 as an Apple Mail replacement with only 2 of my email accounts.

Now I want to convert entirely out of Apple Mail. First I made a backup copy of the entire Thunderbird folder located in the User/Library folder onto an external hard drive that I then disconnected from my computer.

Then I downloaded the latest version 145.0 (aarch64) and installed it. (I still have the other 2 versions on my system) I opened it up and got into the profile manager (troubleshooting then about profiles) and discovered that I have 4 of them. I made the one that contains my archive the primary one. It does not have any connections to a live email account. I've only ever imported an .mbox file. Everything that I've archived is there. This is profile Number 1. I renamed it Archive so I could keep track of it.

Then I opened up each of the other 3 profiles in a new browser in sequence to see what they were.

It appears as if I have one that is empty. it opens up wanting me to set up an existing email address. I closed that one down. It's called Profile number 2.

The next one appears to be the current one for the 2 test email accounts. It has them properly configured, showing messages in the inbox and with the messages that are supposed to be archived off in the local folders I had created as I expect. I am calling this one profile number 3.

The third one first had me add the passwords for the 2 test accounts and then it is pretty close to number number 3 but is missing some of the local folders. This is called profile number 4.

Want I want to end up with is 1 profile. I would prefer to start with the one that has all my archive messages in their local folders, and then add the test accounts including all their messages from profile number 3 with its local folders. Once they are safely moved and part of the Archive profile I would like to delete all three numbered profiles. Once I am down to only one active profile and no others lurking about I plan to slowly start adding the rest of my email accounts moving them one by one out of Apple Mail and into Thunderbird.

I've read the various articles on moving out of Apple Mail into Thunderbird So I believe I can add the Apple email accounts to my Archive profile successfully. I have the import tools so I can import the .mbox files from Apple mail into those accounts.

Where I'm stuck is I can't seem to find an article that gives me detailed instructions on how to combine profiles within Thunderbird. All the articles imply keeping multiple profiles active and I would prefer not to do that.

I am sure I am just not searching properly but I am at a loss as to how to proceed. I do not want to delete any profiles or start adding more accounts until the profiles are cleaned up.

Thanks for reading this long explanation and I appreciate any help anyone can provide.

Hello, after ff updated, gray line appeared. It does not disappear after changing theme. I am using laptop and a monitor. On laptop browser window goes fully to the top, but when i drag ff to the secondary monitor, gray line appears. I will attach photos.

I've been using Thunderbird for over 20 years and I run it on two PC (to have a copy at home and in the office) Running 144.0.1 (32 bit) on Windows 10 and same but 64 bit on the other. The problem is with the 32 bit PC although I don't think this has anything to do with the problem.

Came back to my PC today and my inbox emails are not opening. About 88,000 emails in the inbox can't be accesses but the list of the email info are showing. Click on any one and it's blank.

I have no idea why this has happened, my only ideas are they could be connected with one of the following: 1. A windows restart and update 2. Kaspersky internet security deleting a trojan virus from an email in the inbox and deleting the whole inbox file instead - I have already asked Kaspersky support and they said it would not delete the whole file but I'm not so sure. 3. It might have lost the email when doing a 'compact folder' but I think this is unlikely.

When I closed and restarted Thunderbird any new email coming into the inbox worked perfectly but still the 88,000 previous ones were not visible/readable.

Any help would be appreciated as I'm completely stuck It's strange I only had this problem on the 32 bit version of Thunderbird? Thanks, Brian

Recently, if I am playing audio from Firefox on my phone, the audio stops when my phone screen is locked. This did not used to happen and does not happen if I play the same audio from Safari. I am using an iPhone 17 Pro running iOS 26.1. I have tried resetting the phone and removing and reinstalling Firefox, but it persists. The problem does not occur with audio played from the same webpage through Firefox using my iPad, logged into the same Firefox account.

I know nothing about the dev options for Internet settings and minor turned on and it says the remote server is set to production. No flipping idea what this is. Can somebody please help me?

I suddenly this week cannot send email using Thunderbird (v. 140.4.0esr (64-bit)). I receive email fine. I can send email using webmail with my provider. Error message in Thunderbird is: "Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: resomta-h2p-555359.sys.comcast.net resomta-h2p-555359.sys.comcast.net ESMTP server not available (62240/216.183.125.238)." My provider says the issue is not at their end because my server settings are correct. Outgoing SMTP port is 465, connection security SSL/TLS. Operating Windows 11 v. 24H2.
