This happens only on Firefox and Firefox Developer Edition on one of my PCs and not the other. Firefox is version 113.0.2 (64-bit) and DE is 114.0b9 (64-bit)

Anyone experienced this before?

Greetings,

I'm certain this is self inflicted, but for the life of my I can't figure what I did.

I've got Thunderbird installed on two machines. One a Dell XPS 13 laptop, the other a Dell Precision Desktop, both with Windows 10.

I use Resilio sync to synchronize a profile so both machines are displaying the same. I'm very careful about not opening both at the same time. This has all worked perfectly for years.

Everything is fine on the XPS. On the Precision, all the text in the new message window is displayed in bold.

The odd part is the message isn't bold when received by the recipient.

Any idea what it is that I've buggered up?

I've uninstalled Thunderbird using Revo Installer, rebooted and then installed from scratch with no effect.

So, I'm guessing there is a setting that's been toggled in the Registry to cause this.

Any help would be appreciated.

I have noticed in the last few days that Firefox is keeping my Mac from sleeping. This seems to have started around the time of updating Firefox to version 113.0.2 which happened 4 days ago. Any thoughts on how to debug this?

I just went to open Thunderbird and window popped up to setup email account. I have been using this for years. what the hell happened to my program for email? who has the time on checking email to set everything up again? Why wouldn't we be warned this was coming? Do I really have to set up all of my accounts again? What happened to my stored emails and folders that were setup? I am assuming the program updated, but honestly this pisses me off and makes me want to switch clients after decades of use.

Everything under Logins and Passwords, and Forms and Autofill is unchecked. A "Primary Password" has never been set in firefox.

Can't get it to stop asking, which is made worse by the fact that nothing is selected to prompt it nor is anything stored for it to use.

hello,

i've facing this issue for weeks. i've completely abandoned windows server 2019 as daily os and installed windows 10 with latest patches. installed firefox and firefox developer as usual and did my same settings for years. but videos can't be played on reddit, twitter and linkedin. i tried to refresh browser, disabled addons (only ublock and enhancer for youtube is installed) to be sure. but still got nothing. in my laptop with same addons and same privacy & security settings could play videos.

People I email say, when they reply to my email, they get a non deliverable reply, even though I receive their reply. I have my email linked to my Gmail so I can see my Thunderbird emails on my cell phone. Is there a setting I need to change to get this to stop? Lisa

I have used Thunderbird with a POP3 account for years - it has become a large, handy, easily searched database of important information. MY ISP has forced me into Microsoft Office which doesn't support Thunderbird and, annoyed, I've jumped to Proton, which will allow me to continue with Thunderbird and to download my emails. My question is this:

Now that my old email address is no longer supported, Thunderbird goes nuts throwing up a constant message about not being able to connect. How do I stop this without deleting the actual account? (because if I do, I delete the entire database of emails associated with the account.). I just want to disable it so that it doesn't try to connect. And then I will simply add in my Proton email and carry on from there. At the moment, I get the message: "Log in to account "..." failed." and then three buttons - Enter new password, Cancel, Retry - but it doesn't stay concelled. It just keeps nagging me. And if I go into account settings, it won't let me disable the SMTP.

Sometimes, often after an upgrade, messages IMAPed to Thunderbird do not display correctly. In two recent cases I moved two messages from the Spam folder to the Inbox. One of the messages was completely blank except for the subject. The other displayed HTML code instead of the readable messages. Both messages displayed correctly at my email provider's website. Is there a way or can you provide a way to tell Thunderbird to re-import a message?

I'm using the latest version of firefox, at the moment i had a trouble. Text of timeline zone of my facebook hidden, first timeline unhide but other timeline hidden. I'm restart my firefox, remove and resync ... but this error continue. I'm try other browser as chrome, brave no error. How to fix it? I'm the fan of Firefox but user experience too bad with this error I'm upload some images screenshot with error and no error with chrome browser. ++

I have always read downloaded .pdf files in Acrobat. I inadvertently changed the setting to "Open in Firefox" (I got a prompt and clicked it without intending to). I have changed the preference back to "Use Adobe Acrobat" in Settings/General/Applications, but Firefox keeps opening pdfs in a browser window. How do I get Firefox to abide by my preference setting?

Can I have Thunderbird on more than one of my computers? I ask this because each time when I open an incoming email the email says I'm "Writing" an says it is: "From" me not from the person it is from. And on the bottom of every email in my inbox it has this "Warning about unique identity which is me:

At bottom it says: A unique identity/matching the From address was not found. The message will be sent using the current From field and settings from identity "My Name and email".

I have tried looking at all my settings to compare them to my other Thunderbird on my laptop, and also have tried several times to Troubleshoot.

I hope this helps you understand my problem

First time ever. Tested other browsers, sound works fine. Changed no settings when it suddenly went silent. Refreshed. Uninstalled/reinstalled. Nada/nothing. So to not feel as if I've lost my hearing, I won't be using Firefox until there's a fix on their end, already tried everything suggested in troubleshooting and refreshed. It's just not playing well with Win11.

It would be great if you would include posting date and/or date reviewed to all help articles. It helps very much in knowing whether a help article pre-dates the version a user has installed, and in deciding which of similar articles is the most recent, etc. Thanks for considering this!

uninstall bing and micro soft edge...new email xxxxxxxxxxx@gmail.com

After the latest Thunderbird update (version 102.11.0 32bit)the "Inbox" box, which is supposed to show all incoming emails for different accounts, does not display anything, while on individual accounts the emails display regularly. Thanks

(POP3 client accounts on Win10 Home)

Moved my Postbox v3.x POP3 client Profile (mbox, msf formats) to new Laptop with fresh install of old saved version 52.8.0 Thunderbird Client POP3.

Upon first open after the Profile copy to TBird noticed a Popup saying migration updating. Checking version it had updated from 52.8.0 to 60.9.1 (32bit)

QUESTION: Just curious if anyone else has had this happen (?) and is this something that TBird does on it's own to fix any migrated Profile issues regardless of Update settings?

(BTW looking at new Acct settings that came with copied Postbox Profile it still had the [ ] Check for new messages at startup UNCHECKED. All my Mail and settings were there and functioning) [ EDIT CORRECTION, the above BTW line was my confused error of presentation. I meant to say that TBird Options->Advanced->Update it had a selection dot by->Never check for updates. I apologize for my sloppiness therein. ]

I need to change my email address as my provider is closing down. I have seen the suggestion that I make a secondary with my new address but this will nor work as I have the secondary address with the same provider.

I have been trying all afternoon and no matter how fast I am, I am getting this message.

Document Expired

This document is no longer available.

The requested document is not available in Firefox’s cache.

   As a security precaution, Firefox does not automatically re-request sensitive documents.
   Click Try Again to re-request the document from the website.

When I click Try Again, I get logged out of the website I am on. What am I doing wrong? Is there a way to extend the time so I am able to reasonably enter the data into the form and not have it time out. I was able to the enter this information in the past without a problem.

The website is https://www.mysynchrony.com/ and I select one of my accounts and I am trying to add a bank account and I am unable to do so. Please help.
