I keep getting "Undelivered Mail Returned to Sender" messages when sending emails from Thunderbird to Gmail accounts. Can you help? I am using Thunderbird 102.11.2 (32-bit) as POP mail server with email account through pairserver.com (SSL/TSL with normal password). I can send to Gmail accounts with no trouble directly from webmail.pair.com.

Hello, I've been trying to use my Firefox browser for the past week and nothing I do seems to work. Whenever I click the icon on my Windows desktop, it sends me the following Mozilla Crash Report:

We're Sorry

Firefox had a problem and crashed. We'll try to restore your tabs and windows when it restarts.

To help us diagnose and fix the problem, you can send us a crash report.

I've restarted my computer and tried to change multiple settings, but the same pop up message keeps appearing. I've checked the box that sends the crash to Mozilla and clicked the button that says Restart Firefox, but still nothing. There's also a "Detail" button that provides a bunch of information that I'm not sure how to interpret haha but I can try to copy that if you think it would be helpful.

I would appreciate any help. I'm looking to get a new computer (not sure if that is part of the issue), but I'm really hoping to be able to save the bookmarks I had.

Thank you.

Currently Firefox is redirecting http://localhost:8080 to http://localhost:8081 , each time when type the address in the URL address bar.

I have been working with a container wordpress. I have tested in chrome the address http://localhost:8080 and all works fine.

How can we fix that problems, thanks in advance.

I have removed cookies and site data of localhost in Privacy-and-security> Manage-data>

I recently have been unable to send email using the Thunderbird email client with my Outlook email. (See attached screenshots for error and settings).

I am on Windows 10 Pro 22H2. Thunderbird version 102.11.2.

I've tried disabling Windows Firewall but that doesn't seem to help. I also have Thunderbird on my laptop and it works fine.

Let me know if I can provide more info, thanks for the help!

Since probably 3 or 4 weeks ago Ebay through Firefox has been terribly slow. I have selected the option not to track in the address bar and still the same problem. I run ebay through MS Edge and runs perfectly. Happens to me in 3 out of 4 computers. Only in 1 works ok, very strange...

Speed connection in all of them is at least 200mb/s

Thanks.

Moin all,

since some several weeks I'm facing a real anoying problem. Every Youtube (and other platforms) Video shows extreme brightness. It looks like as someone recorded the video directly in the sun. An example is the best so I attached a Photo with FF in the top left, Chrome in the top right and Edge at the Bottom. Only the frames have been a bit cropped for privacy.

The video shown in the screenshot can be found here. Today I also tried a fresh installation of my Win 11 and also FF (Had some free SSD around for that). But this had no effect, it looked the same. The only change I can see is when the Troubleshoot mode is being activated. But only while this mode is active. If FF is being reset or even new installation (like before fresh Win 11), no change.

Cause of this behaviour I also mentioned FF Video Stream is not HDR. The others show HDR but as not every Youtube Video can be HDR I think this is not the Problem. Anyway, I don't want to change my favorite browser which was working now for about 20 years.

Does anybody have a clue what is causing this or is it a bug?

Hello, I hope someone can help me.

Ever since I updated firefox, my cpu is almost at 100%. With only 2 or 3 tabs open. I updated from version 106.0.2 to 112.0.2. Before this update, I could have several tabs open, up to 10 and the computer would run fine. Now with 3 tabs open, it gets really slow. And I can hear my desktop suffering (the fans go to full speed). When checking the task manager, firefox is taking all the memory and the cpu usage is almost at 100%. I have to keep restarting firefox.

The conditions are the same. The only thing that changes was updating firefox. I already searched for ways to reduce the firefox cpu usage, but nothing changed.

Is there a way to fix this? Or how can I go back to an older version of firefox? Because I'm afraid my computer will die from simply opening 3 tabs.

Thank you in advance.

Hello Volunteers,

Ubuntu crashes while moving around a Firefox tab with a mouse, IF the mouse cursor goes thru the top bar of the laptop screen. I am using Firefox V 113.0.2, Build ID: 20230522193126 on Ubuntu 23.04. This could be an Ubuntu problem or a Firefox problem.

Thanks Dilip Deodhar

Can not save images from Google Images, by holding down on the image, and then tapping save image. The menu simply does not pop-up. Holding down on the image results in selection of the image description below. Sometimes you can not save it form the website either, but that is because of website configuration and you can not save it on other browsers, but on other browsers you can save from Google Images by holding down on an image, so it is only the issue of Firefox and not the Google Images website. This issue seems to be present for over 2 years based on online feedback, and it is still not fixed.

I have an extension (completely blank) that can't be deinstalled. I am trying to use the "refresh firefox feature" to get rid of it, but the button simply isn't where it should be. The text is german, but none if these Buttons are the one I seek.

Hello

I'm running Thunderbird 102.11.0 with Gnome 44.1 and the Wayland windowing system on OpenSUSE Tumbleweed. The first time I launch the application after a restart it always hangs with a blank window titled "Home - Mozilla Thunderbird". The same thing happens whether I launch the application using the shell or the desktop icon. If I close the blank window and try again then the application always launches correctly on the second attempt.

This issue started about 4-6 weeks ago before that I never had any problems launching Thunderbird.

Any ideas on how I can debug this?

Cheers Norman

Hello I am new to Tb but I have problems with GMAIL, the synchronization works fine from the server, I can move emails to any folder, send them to the trash and delete them and it syncs in TB, but when I do the same from Tb this does not work well when I move an email to the trash and then delete it from TB it is not deleted in Gmail and stays there until I close TB. The configuration I have is IMAP. and the problem gives me with Gmail because with zohomail it works correctly. What am i doing wrong?

Problem started several days ago......driving me nuts ! Win 10 / X64 / Thunderbird 102.11.1 Comcast e-mail I use Malwarebytes and Norton

I can download from Comcast all my mails with no problems to Thunderbird. I can send New e-mails from Thunderbird with no issues.

However if I use REPLY or FORWARD to send a message I get an error box saying to check my settings. All y settings are fine because I can receive and send messages ( new ones) with no problems. It's only the reply and forward functions that give me the problem. Enclosed is screenshot of the message I get. Tried clearing cache as well as several other minor repairs to no avail. Any suggestions ?

Need to determine why some emails sent to me (from me) do not show in my inbox. If the same email was forwarded to me from someone else, it looks like it comes in (unread mail count increases), but it does not show in the inbox. A search for the email finds it but it does not show in the inbox. Very odd behavior. Only does this for one account of several we have.

I noticed that on Facebook there is not shown data and time on every post. Some posts show this info, the other don't. I cleared cookies, deleted Facebook from history but it didn't help. On Chrome everything is showing normally. I put Firefox in solving problems mode, with add-ons off, it didn't help too. Any solutions?

Hi, I've been having trouble with Thunderbird for a few days now.

I recently turned on and updated my laptop, which shares the same thunderbird accounts as my desktop. I had to update Thunderbird and log back into my google accounts because it had been some time since I last used that device. I noticed that I wasn't receiving emails on my desktop anymore. I did some research and tried applying fixes that I read online.

So far I've tried: Deleting my saved passwords > didn't work Removing the account entirely and re-adding it > Thunderbird failed to find the settings for your email account. Uninstalling Thunderbird and deleting any saved profile data > Same as above.

I did install a new router, a Netgear Nighthawk but I'm not sure if this is the cause of my trouble as both my mother's PC and my Laptop use Thunderbird. Both continue to work.

I use Kaspersky for my AV / security but all three machines also use Kaspersky and I've no issues on two of the three.

I'm currently running TB ver 102.11.0 (64 bit).

Any assistance and clear instructions would be greatly appreciated.

Cheers

I carelessly opened an email and within seconds I had a problem with T'bird. The password vault was locked and although I had the correct password I could not get access. I deleted T'bird and the Mozilla maintenance folder, leaving Firefox in place. Reinstalled T'bird and the vault was still locked. Two a/v programs are negative. I guess there's a hidden folder somewhere that needs sorting out? I much prefer T'bird to anything else so I hope to find a solution. Thanks.

I have a new Mac mini M2, and Firefox will not work. I have had zero problems with FF on my old mini.

I am operating MacOS 13.3.1 (a), and trying to get Firefox 113.0 to work. It will start, but, after running through the new-install windows, it will not load any pages, such as google, and gets stuck in "a checking for updates" loop. Eventually, I have to force quit. I have removed all traces of previous versions from my system, and restarted, then done a clean install of FF, without loading any previous information, files, tabs, etc. Just the bare bones. All antivirus is off. No plugins other the the Open H264 and Widevine Content Decryption. No extensions. Set on standard privacy.

I have done this several times. Working in trouble shooting mode makes little difference. I can sometimes open 3 tabs before everything goes south.

Safari is working fine.

I'm about to give up on Firefox. Any help would be appreciated.

I have 3 email accounts in Thunderbird, all POP3 type via Spectrum.

I’ve been having intermittent problems with one of the accounts, namely that I can't delete some messages in the Inbox. (The Inboxes for the other 2 accounts seem to be fine.) When I try to do so I get a "Thunderbird is not responding" message and everything freezes. I have to use Task Manager to exit the program.

I went to Help >Troubleshooting and cleared the cache, disabled add-ons, etc., but no luck so far.

I would really appreciate any suggestions. If the only remedy is to uninstall and re-install TB, how do I do that?

Thanks!

In thundertbird 102.11.0 (32-bit). unread messages remain unread aftrer selecting the message. I have to opeen the message in order to mark it read. This is different from what happened beforew. just selceting the message would make it Read. This is slow as I dont always need to open messages In Settings > General, Reading and Display, Automatically mark messages as Read ius checked, and Immediately on Display
