Thunderbird ერთობის განხილვა

TB suddenly moves messages from inbox to trash automatically without any interaction. Search through the forrum shows that it has been asked for already, see https://support.mozilla.org/en-US/questions/1588804, similar postings can also be found with you search engine.

As described in other postings, the messages are moved from Inbox to trash. When moving them back manually from trash to inbox, they are moved to trash again immediately.

• it happens for the default account only,
• there're no filters at all in TB,
• junk detection is disabled,
• Settings->General Storage is all disabled,
• (account)->Settings->Server Settings has checked "move deleted messages to trash",
• (account)->Settings->Storage is all disabled,
• Inbox->Properties "Repair folder" does not help,
• Inbox->Properties "rules is set to "use account settings" (and greyd out "do not delete messages"),
• exactly same behaviour when starting TB in save mode,
• manually deleting all *.msf files (for inbox) does not help,
• manually deleting xulstore.json does not help,

Additional notes, which are not related to the problem, IMHO:

• IMAP on port 993,
• no other clients anywhere are connected to that account,
• TB configured for more than 10 accounts, more than 500 folders and sub-folders,
• host with > 16GB RAM, TB uses 3GB virt,
• problem observerd in older TB also, at least 13x.x

I'd be happy to debug/trace the problem if someone can give me detailled insructions how to start TB with debugging. Please feel free to ask for about:config settings as they are non-ambiguous and language independent ;-)

Thanks.

I have set a custom theme on my Thunderbird on Linux. As you can see by the attached image though, the menu bar is hard to read when you get to the right side. Dark background and dark text doesn't really go together. Is there a way to make the background of the menu bars a solid color or something less see-through so the text can be read? I want a light theme, but I need to be able to read the menu.

Since changing my gmail accounts settings in thunderbird under Synchronization and storage so as not to store a local copy of emails. Thunderbird, after a while, is no longer able to authenticate to imap.gmail.com. If i delete the associated oauth2 saved passwords, restart and regrant access. Thunderbird is ok for a couple of hours but then fails again later. Thunderbird ran fine for a couple of days before i changed the synchronization settings.

Any ideas on how to eliminate this annoyance?

I have thunderbird installed on my PC, and my main email account is a gmail account. I download from gmail using POP protocol (SSL/TLS connection security, OAuth2 authentication). I have been using these settings for a long time (15 years?).

This afternoon, thunderbird stopped downloading my messages. No error messages : just "no new messages to download".

I can see (by logging directly into my gmail account using my browser) that there are new messages on the server. They're not spam or junk, and they're not getting downloaded into my (local) spam folder. They're not getting downloaded at all.

I still have room on the google server (it's about 87% full), and room on the hard drive on my computer (about 3 GB).

Where does Thunderbird put attachments that I open (say a PDF I opened)? Sometimes these documents are sensitive and I want to assure any temporary copies are deleted, either manually but preferably automatically

Will setting "browser.helperApps.deleteTempFileOnExit" to "True" help?

Thank you.

This will make more sense if you look at the attached images first. If I create two one-hour appointments back to back on the same day--meaning the first appointment ends at the same time the next one begins (or with a 1 min gap), and then I look at my calendar in Week view, I'll see 2 full-column 1-hour blocks stacked one above the other as in the "1hr appt.png" attached. This appears to be the correct way it should appear.

But if the earlier appointment is only 30 minutes, they appear differently, as in the other image "30min appt.png". squeezed into two columns. I would like them to appear as a single, full column (as with the 1 hour appointments), which it does in the Day view.

Is this a bug? Can I change this behavior?

hi :-)

My Thunderbird uses between 19 and 34 GB of RAM. It's cyclical (with a period of about 10 minutes).

What do you suggest?

Do I need to perform a performance diagnostic? https://support.mozilla.org/en-US/kb/profiling-thunderbird-performance

Do I need to follow all the steps listed on https://wiki.mozilla.org/Thunderbird:Testing:Memory_Usage_Problems#Diagnosis_Steps, or can I skip some of them?

When an email that is part of a thread is selected the delete button changes places with archive so I end up with a bunch of archives I don't want because I get a lot of mail and delete is my favorite key to spam.

Is there a way of changing this placement behavior or do I need to hack the source and if I do need to go hacking can someone point me in the direction of the file with this evil thing.

Hello,

I'm currently using the thunderbird client to open a zoho mail account. I've set several filters (around 40) so that incoming emails are automatically redirected to the appropiate folder. If I click on the download/refresh icon (the little cloud with the downwards arrow), new email isn't received. On the bottom, a small message appears ("No new messages on the server" or something like this). You may think that that is precisely because I don't have new emails but if directly go into any of the folders and once again click on the download/refresh icon all of the emails that were supposed to go into that particular folder appear all at once (even mails that are 2 or 3 days old). Now every day I have to go into all of my 40 folders and click on the refresh button.

I look forward to your help. Kind Regards.

My computer was hacked a month ago, well... I got phished when I was sent an email that looked like it came from a client, it was a bit premature to receive a file from her but... it was very late, I wasn't at my best, and there it is. I always thought I was savvy. So. I did catch it in time to save my Google account and they didn't succeed in getting at any money, did lose my longtime alt-email address. My computer tech was able to restore most of Thunderbird, except for all my client information (18 years' worth), which I theorize is because the bad file was filtered into my client folders so those 2 main/many subs were deleted (or it could be because those client folders and a couple others missing were near the bottom of the folder tree and the tech guy's backup program failed at that point, he did try again but no luck). Fortunately I still keep a paper schedule so I was able to figure out who to talk to, and the autofill feature of TB was able to give me most of the emails I needed. [I have since learned about and have moved my Profile into my Documents in a separate folder so that my cloud backup picks it up every day (idrive). I really think it should be a LOT LOT easier to find and utilize the information on the Profile because EVERYONE should be backing that up every day, and the best way is to automate it. [My tech guy (re)installed Windows 11 Pro, I had Home by preference, have a tutorial from a trusted source about going back to Home without losing anything, because I do not need or want the architecture of Pro. But not doing that until I get my computer stabilized.]

All that said, to get to the point. When I collect email in TB (I have a gmail account using POP into TB as I do not like syncing and use TB to track), I usually have more than 200 emails at a time before I d/l into TB. Several times each d/l session, I get the following error message (header is cut off, it just contained my email address):

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

I have write privileges and there is plenty of disk space. I press OK and the d/l continues for a few more emails and then stops. I then press F5 again to start d/l again. Several times a session. There is no information about which folder isn't there or what is missing or causing the error.

It appears to me that the filters are telling TB to filter into a now-nonexistent folder. I did reconstruct my client folders, but plenty of room for error there I imagine (I use QuickFolders and that actually told me which of the visible tabs no longer existed). My old laptop died in the process of all this so no longer have another version of TB as a guide. I have 367 filters (been using TB since Eudora went away), but they are only searchable by name of filter, not by possibly now-missing folders.

1. I assume that this error only means the email isn't filtered, it doesn't mean it has been deleted or anything. yes? Or am I totally wrong about the meaning of this error message, and if so, please help! 2. What can I do to fix the error? With 367 filters, it would be nice if there were some way I could figure out a way to know which filter is failing, if indeed this is a filter problem?

Thank you for any input about this. I have tried and tried to figure this out.

All best wishes, --Victoria

I have just setup Thunderbird and it seems to work fine. when I login it asks me to to enter my password and if I follow the instructions, I am in, fine. But if I just cancel without entering my password 4 times I am in as well. Is there an settings I need to change so I can not open my mail without my password? I am using Windows 11

After upgrading from Mint 21.3 to 22.3, Thunderbird no longer offers me the option of setting email alerts for events. Details: - I have Provider for Google Calendar installed - I've tried adding my calendar as "Google calendar" and "On the network" but neither offers email alerts. (On the network works better for responding to invitations.) My current work-around is to go to the google calendar app on my phone and set an email alert after creating the event in Thunderbird. That works but is a pain. This worked before. I suspect it's more a configuration issue and less a Mint version issue.

Quick Filter does not return correct results in Unified Inbox (Thunderbird 140.12.0 ESR)

I'm using Thunderbird **140.12.0 ESR (aarch64)** and believe I've found an issue with the Quick Filter when searching the **Unified Inbox**.

• • Steps to reproduce:**

1. Open the **Unified Inbox**. 2. Open the Quick Filter bar. 3. Enter a search term (e.g. "maddy").

• • Observed behaviour in the Unified Inbox:**

• With no "Filter messages by" options selected, entering a search term does not filter the message list.
• Selecting **Sender**, **Recipients** and **Subject** still does not return the expected email.
• Selecting **Body** changes the results after a delay, but the expected email is still **not** returned.

If I open the **actual Inbox** containing that same email and repeat the search:

• The expected email is found using **Sender**, **Recipients** and **Subject**.
• When **Body** is selected, the search takes longer and eventually returns additional matching messages, including the expected email.

This behaviour is reproducible with multiple search terms and suggests that the Quick Filter does not search the **Unified Inbox (virtual folder)** correctly, even though the same search works in the underlying physical folder.

Could you please confirm whether this is a known issue or a bug?

Got a new macbook, did migration from the old to the new. Thunderbird failed to migrate. The icon on the desktop did, but it is not listed in the application list. Both are running the same software version, Tahoe 26.5.2. Talked to Apple, they tried to help, but in the end, they answered that it wasn't their software, so contact Thunderbird. Thoughts???

Downloading messages is now noticeably slower on an older desktop if the 'Inbox' folder is selected/focus. If focus is changed to a different folder (i.e. 'Sent') the message downloads become blazing fast.

Deleting messages seems slower as well and I think it is related. May involve inserting/deleting entries in the grid.

End user here, with Thunderbird for years, now on several machines that I use. Keep getting the warning window about "ESR" change. I have no wish to re-install Thunderbird, on each machine, nor to go beyond the normal updates. Can't tell which "channel" I need to choose. Unwilling to just guess. Could re-install on all five machines, if that's truly necessary. Hope not. An explanation of the simplest way to dispose of this issue, is the help I'm looking for. I think I'm currently set to the lower case address. And arranged such that each machine updates to the current content.

I got an eMail notification about an upcoming update for Thunderbird snap/flatpak configs, but I don't see any entry for Thunderbird in my "~/.var/app/" directory. There is an entry for Firefox, but nothing for Thunderbird. Yet Thunderbird still updates regularly and successfully.

What should I do, in order to conform to the eMail notification instructions?

Running the command "snap info thunderbird" returns the following --

For five or so days, when I go to send an email on my iMac, I get a message saying SMTP server won't send it. If I go to webmail, it sends, and if I use my iPhone it sends. Rogers/shaw has walked me through testing and nothing is wrong their end. Is anyone else having this problem?
