How do I adjust settings to prevent Thunderbird 139.0.1 from converting color jpg files to black and white on my new Macbook Air. Old Macbook pro using Thunderbird ver 128.11.0 did not have this problem with the same email and attachment!

Multiple times a day when switching tabs the entire screen will turn gray and become entirely unresponsive, requiring me to close and restart the app. This has been happening for weeks. It does this regardless of the number of tabs I have open, and continues to do this even after clearing the cache. There is also no report for it in about:crashes.

When the app is going to turn fully grey when opening a new tab when I scroll down and the address bar moves away there is a gray box where it used to be. Also, when opening a new tab the homepage won't appear; there is no "jump back in" or "recently visited" section, just a fully gray background.

Sequoia 15.5 Firefox 139.0.1

Firefox recently enforced an update. After this update, I can no longer open file browser for attachments if a website offers this option (example: this very form, Browse... button does nothing). I can also not Save to PDF any more. In both instances, a spinning wheel will appear and then nothing will occur.

I have two computers on which I use Thunderbird. I have never been able to successfully copy my email filters from one machine to the other, no matter what method I employ. It seems that this should be at least part and parcel of copying my profile to the new computer, but I find I have to rewrite the filters yet again. Please assist.

In the last few months I noticed that I could not completely connect to Facebook on Mozilla on my desktop, I could access from my phone and other web browsers though. I tried clearing cookies, cache, etc. without improvement and just gave up. Now I'm beginning to have issues with other sites not loading completely or at all (Amazon, Yahoo, gmail). I again have tried clearing cache/cookies but its not helping. Just like with Facebook previously, I can access Amazon, Yahoo, gmail, etc on other web browsers from my desktop; just not on Mozilla.

Beginning on May 19,2025 my email will no longer download from centurylink to my Thunderbird program/account. I've tried talking to both centurylink and brightspeed that took over centurylink. They were completely clueless.

I do not want "recently bookmarked" to appear with my Bookmarks. How can I remove it? Right-clicking and changing the "browser.bookmarks.showRecentlyBookmarked" preference no longer work.

I normally use Fedora but my Fedora machine died yesterday. For a time being I want to use Thunderbird on my Mac.

I have a backup of my thunderbird profile directory from Fedora 42. This corresponds to thunderbird-128.8.0. On the other hand, the current version on the mac is thunderbird-138.0.2.

1. Since the version number is higher on the mac I think I will be able to use the old 128.8.0 profile with the new mac version ?

2. If I do this, I will not be able to transfer my profile back to Fedora when I get it working again (because the version number there is lower) ?

3. Is there a way from me to install thunderbird-128.8.0 on the Mac so that I will be able to transfer my profile back to Fedora ?

I m trying to set up as my third email in thunderbird an account which is mickel@embarqmail.com. It sets up using the manual settings following their server instruction fine. But it will not accept my password. I know it is correct because I can log in on their webmail site. What can I do? Any suggestions would be greatly appreciated.

I currently use the Daily version of Thunderbird V141.0a1 and I am using it to connect to my Gmail account via Imap. Recently the client has started showing two Junk folders, one I am assuming is for the Thunderbird Junk mail settings, which is being shown as being on the gmail server but the folder doesn't exist when I use the web interface into gmail, the second Junk folder is actually the server's Spam folder which the Thunderbird client has recently started showing as the name Junk. If I open that folder it displays the email the server has classified as spam, and if I attempt to rename that Junk folder back to Spam it fails with a message that the Spam folder already exists. How do I rectify this situation?

This is a question about the All Mail folder and the Important folder. I wasn't able to find out in the documentation.

There are more emails in the All Mail and Important folders than can be accounted for in my archives, send and received folders. I counted 545 in my archives. I have 14 in my inbox and 51 in sent mail. I therefore have 610 emails in total. The Trash is empty.

There are 852 emails in the All Mail folder, and 550 in Important. The totals don't match up to anything. I find this confusing.

In the Important folder, only 2 are actually tagged as Important. What are all of the other emails doing there? Can I safely delete them? If any of them are also in my archives, will they also be deleted from there, or are they safe? Does the same go for the All Mail folder?

Win 11, latest FF version. A few addons, that never cause problems.

Firefox keeps freezing. I've checked Task Mgr, Event Viewer, Troubleshooting - and cannot find out why this is happening.

Restarted 3 times, but when I open outlook.com, the mail freezes. Open tabs keep freezing, so I'm unsure the culprit.

I'm migrating an existing Mozilla Thunderbird account/email from Windows 10 computer onto a new Windows 11 computer; I've downloaded Mozilla Thunderbird from the download site onto the new Windows 11 machine and set up my credentials, but initially none of my Local Folders were visible; then I exported the %APPDATA% site where my profiles folder lived on the Windows 10 machine and imported it into the %APPDATA% site on the Windows 11 machine, and now, for some reason, I have 2 instances of my email name, 4 instances of a Local Folders ... and even though I'm getting/sending email from that Windows 11 machine, the Local Folders remain empty and the tools to move inbound emails into them are not working. What should I do?

I've been using Thunderbird for about 15 years. I just downloaded and installed V139. Thunderbird is now unusable. In the past, performance was great. Downloading email was fast and my filters moved the messages to the appropriate folders with no issues. With the current version 139, downloads take up to 5 minutes for only 4 or 5 messages. The filters run incredibly slowly. I can't scroll either the navigation pane or the preview pane or the messages pane. Version 128.11.0esr runs just fine with no issues on my other system. Both systems run Win10 at the same maintenance level. After all these years, I don't want to change email clients but if this situation doesn't resolve, I'm afraid I will have no choice but to toss Thunderbird in favor of some other solution.

How do I get back to version 128.11.0ser for this system?

Hi,

I'm just a lowly user that happens to use Linux Ubuntu on three computers. I'm having trouble with my email client, Outlook which Thunderbird is handling 'fairly' well - but not perfectly by my standards (or desires).

I may be a small player in the big world of the internet, but I receive around 250 emails per day, and yet roughly half of them are considered "junk" as far as I'm concerned. I know the way to 'train' Thunderbird to recognize junk emails, but that is an ongoing task that consumes too much of my time.

I want to consider the emails I receive from specific websites or 'domains' (sorry, I'm very lax in knowing the proper terminology) as junk to greatly reduce the number of emails I receive from these sites.

As an example: I receive an email from "renewMB8w1@SalonEvSalBoroTo.de" and have no desire to read or respond to it, yet it is in my inbox. When I click on the "junk" icon, it goes directly to my junk folder. But that just "junks" the message sent by "renewMB8w1" while many other similar messages often with the same subject matter come through with the same "SalonEvSalBoroTo.de" domain (again, sorry).

I wish to stop all emails from "SalonEvSalBoroTo.de", as well as others doing the same thing even from accessing my email. And if not, can I at least get Thunderbird to send any email from "SalonEvSalBoroTo.de" (and others doing the same thing) to the junk folder? Or better yet, to the delete folder?

Thanks for reading, and I'm sorry if I'm a very wordy person. I just hope I got my point across.

Best regards,

George Generke
