Can I upgrade my Thunderbird 115.3.1 from 32 bit to 64 bit?

My Thunderbird has recently automatically updated to V115.3.1 but remains 32 bit. When I go to the Thunderbird download page there doesn't appear to be a choice of version.

In the past, I had followed this post and created the userChrome.css file so that when I have my emails shown in Table View, if one email within a thread is unread, the whole thread is collapsed, but the subject line remains in bold.

With this latest Thunderbird update to version 115.13.1 I have lost the functionality; now the subject line of the collapsed thread shows as underlined. How can I go back to my preferred bold view?

Thanks

I have been using Thunderbird for years to access several @charter.net email addresses, lately administrated at Spectrum, which took over Charter. Everything was working normally until today. I can still receive emails, but when I send, I get an error message asking for a password: "password required for outgoing SMPT server" Manually entering a password in that error message box doesn't help. Spectrum support is not helpful beyond confirming that my email sends and receives normally as long as I access it on their website. Three clues: 1) Spectrum recently announced "new and improved" email. 2) One customer service person described my email addresses as "legacy". 3) My gmail address sends and receives just fine from Thunderbird as usual. Any insights appreciated! Thanks!

Comcast suggested I change my password, so I did. It worked on my laptop but not here on my PC, I can't access Tbird emails on the PC. It will not recognize my new comcast password. HELP

HELP HELP HELP Duplicates continue to be generated as of latest Thunderbird Version 115.6.1. Final Solution?? Running on my MacOS Ventura 13.6.3 (22G436). Fully updated and kept as my babe!! Same as my Thunderbird. Using the [**Remove duplicates...**] official tool to fix it, but continues to appear always after some time.

Use a lot of dayly maintenance on my mails, creating _new-folders_ continuously and moving mails depending on subjects as needed. Continuously maintaining, Always _empty-trash_ followed immediately by _compact-folders_ Always try to do weekly backups.

Duplicates Still never ended since so long been reported!! Any way to fix the issue once and forever??

Do not need/want to suffer a complete platform crash on my loved mailer. Would be a complete disaster. Obviously I keep on backing up once per week.

Thanks a million if you try to help, and kudos if you solve it. Take care.

I've just installed TB 115.6 on my MacBook to see if I like it better than Apple Mail. There is one thing that seems weird to me. Fonts are displayed larger in the Read window than in the Write and Reply windows.

These are my font settings: Default font: Helvetica, size 14 Composition, HTML Style: font: variable width, size: medium

Now if I send an e-mail to myself the font looks larger once I receive the message than what it looked like when I was composing it. And then if I reply to this message the font becomes smaller again in the Reply window.

The font in the Write window has the exact same appearance as in Apple Mail where I also defined Helvetica 14 as the default font. So my suspicion is that the fonts are somehow scaled up in the Read window. But why? And how to change it so that the same font looks the same everywhere?

Most of my emails are going to trash, once in a while I may get one in my inbox, not very often. I now just go to trash for my emails, I am not very tech good but have tried and my son also tried, but we couldn't fix it, we probably may it worse. So I am coping by using trash as my inbox. I know this is not a permanent solution and would very much like to know what I did wrong and get it fixed so I won;t screw it up again. Thank you for your time.

I'm having issues with Thunderbird E-mail. There are folders disappearing and re-appearing in different locations. Also, "duplicate" folders are being created and stored in the e-mail folders list where I keep messages I've received and saved. I've been with on-line assistance through Centurylink help trying to find out what is causing these problems. I have exhausted Centurylinks help when they asked me for the Filters in/or that Thunderbird uses. I'm unfamiliar with where or how to find them. Any assistance would be greatly appreciated!

if I schedule a meeting locally for 9am some attendees receive the meeting scheduled at 8am (1 hour earlier than actual). I have checked my thunderbird date and time settings and they are correct. The attendees claim their settings are correct but between the 2 systems (Thunderbird and Outlook) there is an hour discrepancy. This is causing clients to miss my meetings. Please assist.

Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) smtp.gmail.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again.

What can I do?

After updating to TB 115.5.2, we keep getting the following error message when we try to send or forward an email: Sending of the message failed. An error occurred while sending mail. The server is not responded. No such domain at this location. Please check message recipient "xxxxx@gmail.com" and try again. I get this error on all emails we try to send. We get this same error on my spouse's computer also that we use Thunderbird with. I have already checked settings with my ISP and the POP settings are correct. We can use other mail servers such as outlook.com and gmail.com using Thunderbird. ISP is cis broadband. have checked firewall, have uninstalled Thunderbird and re-installed without solution to problem. ISP has checked port to make sure it is not blocked.

incoming emails do not seem to be effected.

Hello Community Please help me to start again with Firefox from scratch. Last Month I downloaded Thunderbird email app and set up with a new email account using mailfence. Now I find that my mailfence email address was only a free trial and I have to pay to continue to use. I now wish to set up with my original free email with gmail. I did uninstall the Thunderbird app and then installed from fresh. Unfortunately it still has the mailfence email remembered in the Thunderbird App. How so I start again from scratch using my gmail account instead of the mailfence account that has now expired? Thank you in anticipation of you help.
