System specs below. Thunderbird is set with 1 account: A paid Yahoo email, with a LOT of messages (well over 36K), using IMAP (Yahoo only lets the most recent 10K come down via IMAP, sadly). Most emails do download and are correctly rendered. But around 10%, starting usually a month or so back from the high water mark of last update, show email source code (text of headers, mimeparts, etc.) for a totally different email than the one highlighted (a few days later, different sender, etc.) Checking the message on Yahoo, it renders correctly. There is no pattern to the corrupted messages: they can be from mailing lists, company marketing mails, an alert from my local town, whatever.

Once the error occurs, it is consistent across Thunderbird shut-and-restarts (still showing same wrong email source as before). Emails to either side (earlier and later) render properly in the message pane.

Double Clicking the message to it's own child pane renders a pane with Subject and From as blank, and the same email source text for a different email. Forwarding the email puts the email source code in as text (I was hoping the act of refreshing and reformatting might grab the correct content, but no).

Doing a Repair Mailbox (which seems to mean "download headers again, then download all the mail again" does seem to correct for a time (including the previously corrupted emails now rendering correctly)... but within a day or two, a new crop of messages will be corrupted, and the dance starts again.

Windows 10, 64 bit. Norton 360 set to exclude all mailbox directories. Thunderbird 115.12.2 (64-bit), though this has been happening since 110. No plugins, no extensions.

Are there diagnostic logs or other info I can share that can help us figure this out? I really like Thunderbird, but it's just unusable here. Outlook, Apple mail, other tools don't seem to have this problem.

For two days will tab crash for TikTok. For years, will not allow access to certain sites and no contest entries for the last few months. Worked before. No phone help and to download the browser doesn't work. I was upset as won't load TIktok and I NEED IT as use it daily. Please fix it ASAP!! I wasted time contacting Monzilla, as was only link for Firefox. They told me no help wasted today.

Hi, I have been having this issue for a while. The search suggestions in the address bar are missing. I mean that the entire drop-down box never shows up. There are no search engine suggestions. There are no history based or bookmarks based suggestions.

The search suggestions is ticked in the settings. And I also disabled hardware acceleration.

Steps I took to troubleshoot: 1. Refreshed Firefox through troubleshoot mode. 2. Restarted firefox in add-ons disabled mode. 3. Tried creating new profile. 4. Tried using Firefox nightly and Dev builds. 5. Got fed up. Switched to Floorp. 6. I also tried a bunch of about:config modifications, that were suggested in earlier such support posts. None to any avail. 7. Tried it on an entirely different windows. And again, the minute I log in, the search suggestions are gone.

This is when I realized, the issue was popping up whenever I log in using my mozilla account. I tried any firefox alternative without logging in and the search suggestions work. The minute I log in with firefox account/mozilla account. The search suggestions stop. This has to be something due to sync is what I guessed. And I stopped sync. And reinstalled. Then the issue resolved. But the minute I log in it reverts back. And no search suggestions.

The search suggestions do not work on any windows based system. I checked my android device and suggestions are working. Sadly, I do not have access to any other platform.

So at this point I was very much frustrated. So someone please help me out. I will give whatever logs you need. But fix this. I need search suggestions. At least bookmarks and history. I believe it to be a core part of the experience.

Not even recently searched are in suggestions. That drop-down box itself is missing.

Hi, I've received the email below from Microsoft today.

I have 15 email accounts linked to Thunderbird mail and use up to 5 of them daily. Sometimes 'instant' communications on one or more of my accounts can be important.

Will Thunderbird mail still function in the same way from 16th September?

I apologise if this question has been answered somewhere else. I searched but could not find it.

"The safety and security of your information is top priority for Microsoft. To help keep your account secure, Microsoft will no longer support the use of third-party email and calendar apps which ask you to sign in with only your Microsoft Account username and password. To keep you safe you will need to use a mail or calendar app which supports Microsoft’s modern authentication methods. If you do not act, your third-party email apps will no longer be able to access your Outlook.com, Hotmail or Live.com email address on September 16th.

What do you need to do?

If you are receiving this email, you are currently using an email or calendar app that uses a less secure authentication method to connect to your Outlook.com email account. You will need to upgrade your third-party mail and calendar app to a version which supports modern authentication methods.

Microsoft provides free versions of Outlook for your PC, Mac, iOS, and Android devices which can be easily downloaded and connect to your email account. Using an updated version of an Outlook application will ensure you are connecting in the most secure way.

How can you set up your Gmail, Apple Mail, or other third-party mail application?

Various non-Microsoft applications will have their own steps for connecting to your Outlook.com email account using modern authentication methods. See our help article - Modern Authentication Methods now needed to continue syncing Outlook Email in non-Microsoft email apps. However, you may need to contact the creators of those applications to provide you with instructions. In many cases, simply removing and re-adding your account with the latest version of that application will configure it to use modern authentication methods."

I want to print a Firefox PDF document. It is a credit card statement downloaded off the issuer's website. The PDF file Properties dialog shows Page Size 6.92 x 14 in (Portrait). The thumbnail preview of the document shows the pages in the 6.92 x 14" format. I want to print this document to 8.5 x 11" paper WITHOUT HAVING THE DOCUMENT SHRUNK TO FIT THE SMALLER PAPER. Shrinking the document results in a printout that I cannot read without a magnifier. This is unacceptable. I don't care if the bottom 3" of each page are cut off (mostly that 3" is blank anyway). All I want is to be able to print out a document I can read. NOTE: I have tried using the print dialog option "Size to [choose % magnification]," instead of "fit to page width." This does not work. The print image stubbornly refuses to magnify, the print preview still shows a legal sized document crammed into letter sized paper, and I'm still stuck with a shrunken document with teeny tiny text that I can't read. NOTE: I have also explored using the "simplified" print setting instead of "original." All that gives me is a text explanation and the original document itself disappears. So no joy there either.

Firefox 127.0.2 (64 bit), Windows 11.

I recently converted to Firefox from Chrome. I use wikipedia a lot, and am used to being able to quickly enter 'w' into the search bar to bring that up as the first result. This was something that I could do without hassle on Chrome, but not something that I can consistently do on Firefox. My settings are synced across devices, yet the first result for 'w' in the search bar is (was) 'www.google.com' on my desktop, and 'wikipedia.org' on my laptop. I created a bookmark for wikipedia.org named 'w', which didn't work, I wiped any instance of 'google.com' from my search history and now 'w' in the search bar gives me 'www.youtube.com' instead, wonderful.

Any advice would be great

I composed an outgoing email message that I wanted to keep for future use, and saved it as a Template. That not only saved it under the unified Templates heading, but created a second appearance of my main email account with its own Templates subfolder. At that point I decided I really didn't want to keep it after all, so I deleted the message, but the second Templates folder didn't disappear; its still on the tree list as an empty folder. Right-clicking that folder doesn't have a Delete function, but it does present a Repair option, but running that doesn't help. How do I get rid of that unneeded individual email account listing and the empty Templates folder?

When I try to click on certain key buttons in webpages, nothing happens. examples: "Sign in" won't sign me in. A field that lets me change number of products desired won't let me fill change the number. Only seems to be executable (CTA?) buttons. Thanks for any help.

hi, on the top right there is a search bar. for the history i normally highlight the word and press delete, now thats not working, why is this and how can i fix this issue?

"Unable to write the email to the mailbox. Make sure the fle system allows you write privileges, and you have enough disk space to copy the mailbox."

After years of working fine, this message has started appearing whenever TB tries to retrieve messages. I've checked that there's enough space (there's many GB free). I've checked the authorisations of the email folders, they're all fine (Full Control in all cases). I found an answer in a forum suggesting that a rogue antivirus might be the problem, but I'm only using MS Defender.

In desperation I removed the entire Roaming/Thunderbird folder, uninstalled TB, reinstalled it (version 115.12.2), created a new profile for my email address (it's a Yahoo email address, and I can retrieve the emails directly through the Yahoo Mail website with no problems). But I'm still getting the same error message. TB tries to retrieve the messages, it says 'Retrieving message 1 of 105' for several minutes, then the error message popup, and nothing appears in the Inbox. (105 is all the incoming messages as of now since this started happening).

I'm completely stuck. Any suggestions?

Hello, I cannot log in to Twitter/x.com with the Firefox browser. There is a constant loop when registering. Firefox browser does not connect Twitter/X.com.

Thanks for your Help.

Recently switched from Outlook to Thunderbird, however still have Outlook to make sure Thunderbird is working the way I want to.

However any emails that I am sending - whilst appearing in my Sent folder in Outlook, aren't in the same folder in Thunderbird. Strange thing is however, if I use the search bar, it DOES find the email, and says it is in my sent folder.

I've tried sorting by name, by date, by anything I can think of, but I can't find these emails in the sent folder.

The only thing I can think of, is that the emails have not been delivered - even though sent - because when testing it out with a separate email address that I have, the emails appear fine.

Any ideas anybody?

I would like to remove the newly added listing "Local FOlders" from the Folder Tree and restore the Local Folders listing that was moved to the bottom (below All Folders) to its proper place, namely Above Local Folders. This group displays Sent Copies which I use frequently. The newly added 2nd display called "Local Folders" does not disply "Sent Copies" when I click on it in the folder tree. Thunderbirfd decided to move my original "Sent Folders" display to the bottom of the tree when updating to the latest version last night (early morning hours of 6/26/24). I run thunderbird in Windows 10 Desktop on Lenovo w530 using wired internet connection.

Hi!

What is the way to tell thunderbird to index IMAP folders in global-messages-db.sqlite which are not stored locally?

And a more generally, how does this part work, message indexing and remote IMAP folders not stored locally? Here, after removing the database, thunderbird indexed only some very limited set of IMAP folders in the Gloda, but not all of the folders, despite all are checked for "Include in global search". Or maybe it didn't even index whole folders, - I can't say for sure.

Thanks,

Every time I open my Firefox browser (it is my default), even during a session when the browser has not closed, I get a pop-up prompting me to download an update. After numerous attempts to download the update, it still did not show up in my download folder nor did I see the download run or prompt a "finish". I checked download history and finally see that it says it installed on 6/25 but I am still getting repeated prompts to download and install an update.

This is maddening. I am using Windows 10 Enterprise on an HP Elite Desk.

Please help me fix this!

I have Thunderbird version 60.9.1 running on my window 7 64 bit computer. I have kept this old version, as an add-on that I like / need (Theme Font & Size Changer) said it would not be upgraded for later versions of Thunderbird at the time (that I did not like the font size options available at the time).

I have just received an email claiming to be from Microsoft about changes to the way you will now need to get access to Hotmail and Outlook email accounts (Modern Authentication Methods now needed to continue syncing Outlook Email in non-Microsoft email apps). https://support.microsoft.com/en-gb/office/modern-authentication-methods-now-needed-to-continue-syncing-outlook-email-in-non-microsoft-email-apps-c5d65390-9676-4763-b41f-d7986499a90d

To your knowledge, is this message legit and true?

Are the instructions correct for my older version of Thunderbird? If not can you provide correct instructions?

Alternatively, does the latest version of Thunderbird now support the font size changes that the add-on provided and Thunderbird did not provide at the time. If so, I can update to the latest version of Thunderbird.

Thanks,

Brian.

ps Do you do a Thunderbird version for Android?

pps this is what I need on the Theme & Font Size Changer: (see file attached)
