Thunderbird Support Forum

My Thunderbird program froze when I was deleting a couple hundred or more emails at once. Now, every time I open it I get nothing but the spinning wait cursor, and all I can do is force quit the app. I am running Catalina 10.15.7 on my Mac. Is there anything I can do to solve this short of uninstalling the app and reinstalling it? I have archived emails that I don't want to lose. Thank you.

/edit: moved thread from Firefox for iOS (for iPhone/iPad) to Thunderbird section.

Just updated OS to Ventura. Downloaded T-bird 115.0. All good. Using System Dark mode.

However, I find the black BG too harsh in the inbox window. NOT the message window in the bottom half; the list of emails in the highlighted folder.

I looked everywhere and can't kind a way to change that BG colour. I want to reduce the contrast a little to make it easier to read. Definitely don't want to go back to Light mode: everything is too white.

Thoughts?

Thanks Paul

I've been a faithful Thunderbird user since the beginning - and continue to use Thunderbird with our company's Microsoft365 deployment

until Monday of this week -- when suddenly I find that my credentials are being refused.

The symptoms

• XXX: Connected to outlook.office365.com
• nothing in the activity viewer
• no email coming in

I've read and tried all the fixes proposed in the article at https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202 (restarting thunderbird after each step, naturally)

• have authorized Thunderbird to our Microsoft365 tenant
• created and tried registering with a new thunderbird profile
• have set my security settings to 'accept all cookies'
• have used the config editor to remove 'oauth2.issuer' and 'oauth2.scope' values
• I've checked that my account in Microsoft365 has IMAP and Authenticated SMTP enabled

So, since Monday, I've been living in hell, trying to pretend that the Microsoft Outlook app for macOS is useable, but it's practically debilitating to be forced to use that piece of software.

Can somebody please point me to another possible set of steps that I can use to try and diagnose this?

I absolutely hate myself for having to ask for help on this, but I'm at my wit's end...

Hello volunteers -- I downloaded Thunderbird to a newer iMac. The Input messages and folders from my laptop appeared fine, but the addresses look like they are from Contacts rather than the laptop Address Book, i.e., names, phone numbers and postal addresses, but not email addresses. The first image (screenshot from an Apple laptop) is what I want; the second is what I got on the iMac. Is someone able to help me with this? Thanks very much, Susan

I have a new installation of Thunderbird running on Mac OS 13.5. The Received and Date fields are both showing incorrect dates. There doesn't seem to be a logical pattern to the dates being shown. I have emails from yesterday (7/28/23) that are showing dates from as 4/29/02. Emails from Monday (7/24/23) are now showing a date of 5/2/2023. Any thoughts on what might be causing this?

I use a MacBook Pro v. 10.15.7 (Catalina), and I live in the UK. I am going to upgrade my old MacBook Pro to a MB Air, and my Time Machine has stopped working. While researching a solution I found that perhaps there was not enough space on my HD to 'create a snapshot'. So in the process of deleting stuff in order to make space, I found lots of 'duplicates' in the Apps Storage section of the HD, I thought it was safe to delete them as the 'originals' would still be there (same date, same size). I now know I have been very ignorant/stupid (my dog died a few weeks ago and my mental health hasn't been the same since.) However, I was very mistaken and seem to have deleted a lot of my working apps, the most important of which being Thunderbird, which gathered my 4 different email accounts. I'm not sure what version I had last, as it has disappeared, but I'm pretty sure it would be the latest version. My latest download is 68.2.2 (20.11.19). So I tried to reinstall it, but came across this notification 'You have launched an older version of Thunderbird... Create new profile, or Quit.' I googled this but being a not-very-techy senior lady, I can't make sense of what I should do, my main concern being not to lose all my settings, my emails saved in folders, as well as being able to receive and send. I am sure I saw some reference in the past of a library which would contain the emails, but don't know what to do about this notification. The other problem, of course is that I can't completely rely on Time Machine as my last backup is dated 24.7.23. Thank goodness today is a Sunday as there should be less traffic on my email accounts (I am involved with lots of local activities, including being a community journalist). I would be so grateful if someone could help me navigate this minefield and reinstate my app so it works as closely as it did before. Many thanks in advance for your help and patience.

I had to leave Thunderbird because every time I try and create a customized signature, as much as Thunderbird excels in that area, the image storage drops the filename's path every time.

Example:

image loaded: http://rich.allcorn.us/files/headshot.png

when I go back to it: headshot.jpg

It forgets the path, so the file doesn't show up in the eMail. I purposefully put it "on the web" so it could be accessed from anywhere!

When is Thunderbird going to fix this so I can leave Apple's mail program and go back to Thunderbird?

So, I upgraded to SuperNova and my spell checker no longer works. I removed and re-installed the dictionary extension, someplace I think it shows as installed and active. BUT it does not show my spelling mistakes as I compose an email, and when I go to send the spellchecker popup comes up with blanks. Any thoughts on what/how I can fix this. I "really" need a spellchecker.

Thunderbird has its Events, i.e. to-do list items. macOS has Reminders Reminders[1], i.e. its form of to-do list items. It seems that while the macOS Reminders app only operates on reminders which are synced with the Apple iCloud service, there is nevertheless a repository of events/reminders local to the Mac, and it is managed via the EventKit[2] API.

Can Thunderbird for macOS sync its collection of Events with the macOS collection of Reminders, perhaps by calling EventKit?

My use case is that I have a set of events which I curated on a previous version of macOS, using the previous Reminders app. When I migrated to macOS 12 Monterey, the new Reminders app refused to show me my event data unless I synced it with iCloud. I do not want to put this data on anyone's cloud. However, macOS will show me notifications for some of my events. That is evidence that the event data remains locally. I would be happy to use Thunderbird as the front end to curate this local event data. I have just migrated to Thunderbird 115, starting with 115.5.1 on macOS 12.7.1 Monterey.
