My contacts address book is provided by Apple iCloud, of which I have added contacts with avatars for every contact I've received legitimate emails from. However, Thunderbird fails to render these avatars. The result looks like the attachment. Perhaps Apple is using HEIC for them?

My G-mail has all these folders. Do I need to delete the two accounts with the missing folders and reinstall or is there a setting I need to change. Regards Mike

How to remove or hide anchors in Thunderbird

Update: Apologies, seems it was my mistake. While setting up the signature in the first place I *did* pick up a named anchor from a template <a name="_MailAutoSig">. It was buried in the generated HTML, and I have now found and removed it. Problem, such as it was, now solved.

Is there any way either to remove the yellow anchor symbol which Thunderbird inserts in front of my signature, or to tell the client not to display the symbol? I didn't put one in the HTML signature that I use. There's no "remove named anchor" command. It isn't related to the double -- marker, which I've already removed using config. I have no use for anchors, which for me are simply a visual distraction.

Thunderbird is so good in many ways (calendar synch is great - one of my major bugbears with Outlook - also recipient privacy when sending out group invitations) and it can be quite frustrating in some others (e.g. unwanted features that I've had to dig around in config in order to turn off)

Thanks everyone :-)

While checking mail in my inbox, I opened, then deleted a message (message 1). As has been happening lately, there was a significant pause between my hitting delete and the mesage going away. Then I opened another message (message 2), and I found that it had the header for message 2 displayed in the inbox, but showed the text of message 1 when opened. Scrambled messages and headers could be a big problem.

I logged onto the mail server (gmail) directly. It showed me message 2 with the correct header, and message 1 was in trash.

To fix the problem, I deleted message 2 on the server, and waited for it to vanish from the headers in my Thunderbird inbox. Then, I copied it back from trash on the server. After it downloaded to Thunderbird, everything was fine, but I wanted to alert you to the issue. Something evidently can go awry on TB's end to scramble headers and messages, and that is scary.

Running TB 147.0.1 with gmail(imap) as the mail server. I have posted twice in the past week about issues with gmail, and I am suspecting something going on at that end. My TB installation is brand new since then; the problems with logging on and staying connected that I reported only went away when I removed .esr, rebooted, and did a clean install of TB.

Please advise if this is a known problem, and if there are settings I can tweak to prevent recurrence.

Thunderbird has become crazy slow. 5-10 minutes to display an email. It's not my email server because my phone connects to and displays email fast. I have been through all the advice that I can find and cleared, checked, disabled everything that might slow it down. Still crazy slow. If I kill it and restart, I get about 3-4 minutes of reasonable performance and then it just stops. Latest Release Version V147.0.1.

i have a fast machine with 32Gb memory only 60% used, everything else runs fast

I don't want to junk Thunderbird, but it's unusable.

Help!

Hi there,

Is there a way to get checkboxes to select messages or at least a plan to get it in a future release? I saw that there has been an add-on in the past, but not maintained for some years and therefore not possible to use in newer versions. Yes, I know that you can select messages with ctrl and mouse click, but there are others in my family who are not familiar with it and reluctant to get used to it. (have used gmail for too long).

I have ended up with five different calendars. They all have different names--probably because I really don't understand how Thunderbird organizes things in regard to the rest of the internet. Several people in our household share calendars, to keep track of events, tasks due, and medications.

So how do I consolidate all the entries in all of these calendars? I have tried syncing, but that doesn't seem to work. How can I know that when I enter a soccer schedule on (one of) my calendars, it will end up on the calendar that my wife uses to print out our family weekly schedule?

Hi, I have been using TB for many years, when suddenly 4 days ago ( Feb. 1st.) it started as a brand new install, asking to set up a new account, I got no previous warnings or had other issues.

Since then I have done several attempts to get it connected with my profile, among others: - Everything from this article https://support.mozilla.org/en-US/kb/profiles-where-thunderbird-stores-user-data - Importing the Profile from Functions > Import > "Import from another Thunderbird installation" - Reinstalling TB ( without removing the profile)

All of it with no succes, there is no accounts, and no mails, only some empty local folders so I'm running out of good ideas, and I really hope you can help!

BTW, somehow the addressbook has content, as the only thing.

Thanks Best regards Preben
