For about 6 months now, I've been having a strange problem with Firefox leaving behind ghost entries on the Win 11 taskbar.

I have a laptop attached to a dock which is connected to multiple monitors. If I have a FF window open on one of those external monitors and disconnect from the dock, all the tabs that were open in that FF window will become ghost entries on the taskbar. (see attached image).

It doesn't matter if I close FF entirely, these entries remain until I restart the computer. If I click on one of them, it opens up a brand new, blank FF window.

Has anyone else experienced this or have any idea what might be going on? I tried doing some investigating a few weeks back and I remember finding something in the task manager about COM Surrogate that seemed connected, but I didn't get beyond that.

in my 'podcasts' folder I have ~2 pages of folders of the type feeds.json-xxx.corrupt where xxx is some number, see attached image.

With the intention to re-subscribe to my feeds later, I have deleted all other folders in my podcasts folder. Trying to simply delete the feeds.json-xxx.corrupt folders did not work. How can I get rid of them?

(I am using the portable version of thunderbird)

So I'm having issues playing 4K videos fully on one YouTube channel: https://www.youtube.com/@ClearviewDriving

For some reason anything above 1080p gives me bad stuttering but on other channels videos don't stutter or freeze when playing 1440p or 4K quality.

Firefox is updated, I don't use Extensions other than Ad Blocker and I have that off on YouTube anyway. Seems strange that it'd only affect one specific channel.

I have a very good gaming PC too so the hardware isn't the issue.

I have previously (about 1 month ago) connected without issue to my Ionos email account. Today it will not connect. I have updated all the POP3/SMTP settings, read from the Ionos site. I have re-entered the current password too. My Gmail account downloads fine, it is just my Ionos account that will not load. I don't get an error but the last mail showing is in March (2024) and I have had hundreds since then.

My Browser keeps on telling me there is an update... I've updated, reinstalled the latest version and it still keeps giving a pop-up saying there is an update...

How do I get rid of these pop-ups???

In our company, we have recently updated Thunderbird from version 52.3.0 to 115.9.0. Now we have a problem with href links containing file URIs in our messages. We often receive file links pointing to files in our local intranet, which look like this: <a href="file://///intranet.local/dfs/output/movie.mp4" class="moz-txt-link-freetext" moz-do-not-send="true">movie.mp4</a> Up to Thunterbird version 98.0b3 it was possible to open these files by simply clicking the link. But since version 99.0b1 file links don't open any more. Instead, the error console displays the following message: Security Error: Content at mailbox:///C:/Users/username/AppData/Roaming/Thunderbird/Profiles/profilename/Mail/Local%20Folders/Inbox?number=12345 may not load or link to file://///intranet.local/dfs/output/movie.mp4. Fortunately, it is possible to open the link with "Open Link In Browser" from the context menu. But we would like to get rid of this extra click. I already followed the steps in this document: http://kb.mozillazine.org/Links_to_local_pages_do_not_work#Firefox_1.5.2C_Mozilla_1.8.2C_and_newer Interestingly, this document is older than the time, when our problem was introduced into Thunderbird. Consequently, when I follow these steps, file links still don't open in an external application. Instead, they open inside of Thunderbird which is not the desired effect. To put my question in a nutshell: How can I open file links by left-clicking on them, just the way they open, when I right-click on them and select "Open Link In Browser"?

Steps to reproduce: On a Windows computer create a new mail. Press Ctrl-K to insert a link. Enter the following path with username replaced by your windows logon name: file:///C:/Users/username/Documents Save and close the mail. Watch the mail in the drafts folder. Click the link. Nothing happens, but you can see a message in the error console. Right click the link and select "Open Link In Browser". This opens your windows explorer.

Any solution is welcome, even if it's potentially insecure, since our computers don't have any internet access and we can receive internal mail only.

The latest version of Thunderbird has lost the Advanced Search button. I can still access it from Control/Shift/F so the function is still there, but no obvious way of accessing it

if I go to any website then during login it doesn't suggest me I'd or username but suggest passwords in password section although I save both of them please correct this because sometimes it creates turble for me.

We still use some Dell 13g servers equipped with idrac 8. When I'm trying to launch the virtual Console the window opens up but nothing shows. This used to work fine in previous versions of Firefox. I can't tell from which version it stopped but it's not long ago. Also idrac 9 console works fine in Firefox When trying to open console idrac 8 in Chrome it works fine Any idea what could be causing it? Any config switch to tweak?

When choosing biometrics for 2-factor authentication, sometimes Firefox will only prompt for a physical hardware key, and Touch ID does not work. Support for built-in biometrics is inconsistent.

For reference, I am using Mac OS Sonoma 14.4.1 with an ARM processor.

I have 6 accounts on cox.net and today in two out of the 6 accounts, emails that I send are not saved and I get a message "Your message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors. The "sent" folders for these two accounts are grayed out. I have verified that the account settings have the right folder as the destination for the sent emails and have checked that all emails should be saved. I also get a message in Thundebird -The current command did not succeed. The mail server for account xxxxx responded [TRYCREATE} Mailbox doesn't exist. Mail goes out but no copy is saved. Only two out of 6 accounts are affected and I didn't do anything to them before this started happening.

I was able to change some of my message pane background by adding the following to the userContent.css file:

/* Thunderbird userContent.css */

@-moz-document url-prefix("imap:"),url-prefix("mailbox:"),url-prefix("news:") {

 body {
   background-color: #404552 !important;
 }

} @-moz-document url-prefix("about:blank?compose") {

 body {
   background-color: #404552 !important;
 }

}

I also tried adding the following to my userChrome.css file: /* Message pane */

1. msgHeaderView {

 background-color: #404552 !important;

}

1. messagePane {

 background-color: #404552 !important;

}

Why do I still get these two dark gray areas (see attached)? What css do I need to add to get them to be the lighter grey?

Hello,

I have just imported my old email from Outlook to TB Local Folders. Everything works out except some of the email (not all) show a wrong date in the email list. The date show a future date like 2/7/2101, 6:28 AM. Please check the attached image. Any idea?

It used to be that when I typed in the beginning of a URL, Firefox would suggest a massive list of matching URLs from my history that would slowly dwindle as I typed more, but now I get only three suggestions.

I didn't change anything, so is this a change in Firefox? If so, can it be changed back? Or made an option?

Thank you for your assistance in advance. Since I updated my browser, I've encountered some issues when trying to maximize the virtual screen in my tv. I use a Mac and connect the screen to a web TV to watch YouTube in my big tv. However, when I click to maximize the window, the connection becomes unstable, and the virtual screen disappears every time I click the YouTube icon to do this. This problem never occurred before. I would appreciate your help in resolving this issue. Please let me know if you require any additional information from me.
