Whenever i send a Tab from any Device to a Linux Desktop, the Linux Desktop is almost guaranteed to freeze. It doesn’t matter if that Linux Desktop is my "Dingus" PC with 2GB RAM and Wayland, or my "Workstation" PC with 16GB RAM and X11. On both Desktops, Firefox runs smoothly until it gets sent a Tab from another Device, then the whole Linux Desktop freezes. The Desktop doesn’t slow if i open the Tab on the Desktop in the “Tabs from other Devices” Sidebar instead.

Only my Linux Desktops freeze when they get sent a Tab from another Device. Android doesn’t slow when my Phone gets sent a Tab from another Device.

I'm running Thunderbird 140.5.0esr (32-bit) on Windows 10 Pro Build 19045. After the last few updates the columns in the email listings are changing widths from what I've set them, this seems to happen after I close then reopen Thunderbird; which I'm having to do more often these days to resolve weird calendar malfunctions. For instance, the data column would appear so narrow that only the month/day show with "..." at the end, when I know I've looked at this yesterday with the full view of the date and time showing. I've reviewed my options and I've set them individually, set them globally and it makes no difference. Of course I've rebooted, etc. I have over a hundred local folders and they all change differently, of course some look the same but others don't. Most have the same column headings selected but it doesn't seem to matter. Some have the "Correspondents" column selected but many don't.

This is very irritating and I'd like to know why Thunderbird is doing this, and more importantly, how can I prevent this behavior in the future. Thanks,

I recently updated from a very old version of Thunderbird. The new version no longer shows the little popup messages at the bottom of my screen when automatically checking accounts for mail at the designated interval. As I have numerous email accounts (all set up as POP mail), set to check at different intervals, these popups were useful to me - they also showed when I manually checked an account, or all accounts - this also is not happening anymore. Have they been discontinued, or is it possible I turned them off? I did change some things to suppress nags to update Thunderbird during the time I was using the old version, and unfortunately didn't keep a record of those changes. I'd appreciate knowing which function in about:config controls this feature so I can check to see whether it's set correctly. Thanks!

Thunderbird causes my machine to 'hang' from time to time,

1. often for up to a second and usually a number of times in quick succession on each ocasion. Sometimes this happens frequently - say every 5 or 10 minutes - sometimes only after an hour or more since the past occurrance.

2. My machine hangs completely - nothing will work, mouse, keyboard, sound, other apps etc. If I happen to be typing (into any app - including Thunderbird - when this happens, input ceases, the cursor freezes and - if the problem persists for a second or two, Windows reports "[app] is not responding"

3. I cannot be certain, but I believe the problem occurs whilst messages are being retrieved.

This is a very serious problem as it means that I can never leave TB running as the problems it causes are not acceptable.

4. This means I cannot deal with incoming messages without periodically re-starting TB - which is an utter PIA.

I am running Win 11 Professional on a 2-year old machine with 64 Gb of memory. I have run TB in Troubleshoot mode, I have confirmed that the problem occurs regardless or whatever other apps are running (or none) and I have proven conclusively that no other app causes any kind of similar problem.

Looking forward yto hearing if others have had the same issue and what can be done about it.

Hi. Since the last 2 updates, my Bell sympatico email through T-bird cannot SEND anymore emails (No errors are given but the email never comes through). I can receive emails without issue and when I use another tool (like Outlook or go directly through my browser, the sympatico emails come through) I attached the settings for the SMTP in a screenshot if that could help.

Any idea how to fix this?

Hello,

Everything working just fine last night. Wake up and Thunderbird will not retrieve emails.

Remembered this old message I got so I went through and deleted my second email address, didn't help.

https://support.mozilla.org/en-US/kb/thunderbird-and-yahoo

Checked all settings compared to Yahoo, still won't download messages. I can even send a message with my current settings no problem, and it does login, just won't retrieve emails. Gives me a connection timeout.

Anyone have any ideas?

Firefox 150.0.1 Ubuntu 22.04

Problem: When downloading a file from a web page, the list of files and folders in the Download Panel are sorted such that file names and folder names are intermingled, rather than the "standard" folders first, then files.

Discussion: This problem has been happening for a bit now (probably 2 - 3 months or more). Unfortunately, I don't recall exactly which version of Firefox this originally showed up in. At some point recently, the default sort for the Download Panel changed, so that instead of listing folders at the top of the list of download targets, then listing files, now all items are interspersed. For example, previously selecting to download a file from a web page would give the Download Panel contents as:

AFolder BFolder CFolder AFile.txt BFile.pdf CFile.jpg

Now, the list presents as:

AFile.txt AFolder BFile.pdf BFolder CFile.jpb CFolder

I would like to go back to the previous sorting behavior, but I cannot find a way to do this. I have searched the Mozilla help articles without turning up relevant information, and I have searched the internet for web sites that might list relevant information, but either the information I am seeking is not out there (unlikely) or I am not coming up with search terms that locate the information (much more likely).

I am not even 100% sure that this is a Firefox problem (it is within the bounds of possibility that it is an OS problem), but none of my other regularly used programs show the symptom, so it would seem odd to me for it to be something other than a Firefox problem.

I would appreciate any pointers (web pages, help articles, or even just "change this in about:config) on how to resolve this.

RE: How to turn OFF message preview when I single-click on message?

When in TB message list, and selecting a message for an operation by making a single-click on the message, the selected message opens. When using CNTL key to select several messages together for an operation, each of the messages opens an individual preview pane. I have searched TB's knowledgebase, but apparently no other users have this problem.

I am running Thunderbird 140.9.1esr on openSUSE Tumbleweed.

For a long time now, Thunderbird often runs at high CPU (80-100% of one core), for several minutes at a time (5-10 minutes). This seems to happen many times every day, with no apparent cause from my end. (I just got back from Lunch, and the fan on my laptop was going crazy because of the high CPU.)

What can we do to identify and fix this issue?

Over the past few weeks, my typing is continually being interrupted. It did this a few years back, but this is getting very annoying and I am soon to switch browsers if not fixed. BTW on any machine using Firefox, this is happening

For the past.. month I would say, any time I try to use Youtube on my Firefox Browser it nearly always switches over to landscape mode after watching a video. It doesn't matter whether my phone screen's auto rotate is on or off it still does it. Yes. I already tried to turn my auto rotate on to switch it back to potrait mode, it still won't work. The only solution I currently have is closing Youtube all together from my Browser, which really REALLY sucks!!

Can someone PLEASE look into the glitch?!

All of a sudden today I'm getting the message "could not connect to server mail.twc.com; the connection was refused." So, I'm unable to send/receive email. I called Spectrum and they said go to Spectrum.net. Yes, I was able to get my email that way, but that eliminates the ease of using Thunderbird. I've read all the messages about this issue, including changing various settings, but none have helped. Spectrum says nothing has changed on their end and it must be a Thunderbird issue. My current settings are: Incoming: Server Type: POP Mail Server Server Name: mail.twc.com Port: 110 User Name: [my email address] Connection security: None Authentication method: Password, transmitted insecurely

Any other suggestions?

A radio station https://www.wfmt.com/schedule/ that has run successfully until today in Firefox no longer does, There is momentary blip of sound but then silence. It runs fine in Chrome. Another station continues to run successfully in Firefox

When I try to open Thunderbird it keeps giving me a message that it is trying trouble install a new helper tool and asks for my password. I do so, hit the Install Helper button, and then nothing ever happens. I get a spinning beach ball and it never opens no long how I wait. I would be very grateful for any suggestions or advice on what to do.

I am trying to re-install THUNDERBIRD I have done this several times before but Google is causing problems When I reenter my Name email address and password Thunderbird finds the email but then it takes me to google and I have to click allow but then it takes me back to the email install and then tells me it cannot find the Email address with the settings

THE SAME SETTINGS IN FOUND 1 MINUTE EARLIER

I have 2 email addresses and it does the same with both so Thunderbird does not now work on a Computer that I have used Thunderbird for Years
