I-Thunderbird Community Forum

I used Thunderbird for email since I bought a license to Netscape Navigator but now am finding Thunderbird impossibly unproductive because of random extreme slowing when simply editing text.

I thought upgrading my computer and download the latest OS would help, but it didn't. There is something fundamental going on which I hope can be easily fixed.

i have had my computer updated from windows 10 to11 and have firefox ,how do i get thunderbird to open up as it did before , i can get it in google chrome but not the same?

I use Thunderbird on MacOS, but my settings were lost and I had to set up my mail again. This has happened many times and I would like to know why this problem occurs.

Under no circumstances is thunderbird loading a profile (existing or newly built).No crash report. Completely empty. New installed program and/or new installed post boxes + copied Mail-folders from existing profiles into a new profile will work once or twice or a few more times. At least next day TB starts only complete empty. I tried to fix it many times - using corresponding different forums.

Thunderbird inbox shows wrong sender name for message, overriding what the person actually sent with something from its data base. Attached screen shots illustrate:

-- Message is sent from danmargsullivan@earthlink.net. This was a joint account for a married couple. When they sent messages, each would have their Email client show the name of the sender. The husband died several years ago, and now the wife is the only one using the account.

-- Screen Shot #1: When I access the message via Thunderbird, for some reason it overrides the name provided by the sender with something from its data base (in this case, the name of the dead husband).

-- Screen Shot #2: When I access the message directly from Gmail, it shows the correct sender name.

This seems to me to be a bug. But if it's not, is there some parameter I can set so that Thunderbird doesn't "help" me with overrides like this?

Thanks for any help anybody can offer.

Being fairly new to Thunderbird I'm still exploring the possibilities. I know I can display only unread messages in a particular folder by using the Quick Filter / Show only... option, but is it possible to set up a more direct method which requires only one click and is permanently displayed as an option?

Many thanks.

I checked the settings multiple times. The settings you see in the screenshot are correct. These are the settings I've used for the past 10 years. No problems until now. I just logged in today and Thunderbird did not want to work. K-9 Mail works just fine on all my Android devices. This is happening only on Thunderbird desktop.

• To troubleshoot the problem, I first removed the account and added it back. That did not work. • Next, I uninstalled Thunderbird and installed it back. Same problem persists. • This time I uninstalled Thunderbird using Geek Uninstaller to remove all related cache. Install Thunderbird back and try again. Did not work. • Read A2Hosting article a bunch of times: https://www.a2hosting.com/kb/getting-started-guide/setting-up-e-mail/accessing-e-mail-accounts-with-client-applications. Confirmed, all my settings are correct. Thunderbird is still not working.

Until recently, there was an icon to start a new email at the top of the folders column, but no longer. I'd like it back but can't figure out how to. Advice please?

I upgraded my PC, having backed up everything on Carbonite. On installing Thunderbird I cannot get it to recgnise and use my original Thunderbird profile downloaded from Carbonite. Peter Millar

Whenever I open a message from the inbox into its own window, the message text and images are tiny and unreadable until I zoom (Shift-Cmd-+) them larger. And when I reply to a message, the text is also starts out tiny, but gets larger when I Zoom it up with the original message. Similarly, the column-header icons of the inbox are tiny, while the text is OK.

All the rest of the interface is normal and readable, except for the tiny text and buttons in the interface-command/confirmation boxes.

I have experimented with the suggestions in these question-replies, but to no avail:

I can adjust the font size and density from the "hamburger menu", just fine. And the MacOS 15.3.n-on-Intel settings seem right.

What am I missing? What else is there to change?

I can't seem to sign in with two different accounts. I am trying to set up for my wife and I to use TB as email. Can I delete all other emails when I have this account working properly. Thank you for your help. If it helps, I am an old person so not good at PC stuff as young whippersnappers.

Someone is sending emails which are "from my domain" but not sent by me. The only constant is my email address and the name in Correspondents. Is there anyway to create a filter to automatically delete email based on Correspondents "name" ?

Thank you

When composing a message, as soon as I hit the space bar a blue border appears around the message pane and instead of inserting a space the cursor jumps to the end of the message. When I try to go back to insert the space where I want it the curser jumps to the end again. So basically I can't insert any spaces in the message. This has only just started happening, been using TBird without any problems for a long time. Any advice would be much appreciated Thanks Geoff

When an email has been forwarded or replied to several times the original subject line often bears no resemblance to the body of the email so it's really useful to be able to edit the subject.

I've been using the EditEmailSubject MX add on for years but it's stopped working, it gets stuck on a spinning black circle. Can anybody help to get it working again?
