I'm getting daily warning notifications from Mcafee about some virus. Don't even have Mcafee. When I go to Settings -> Privacy & Security -> Notifications, there is no Settings button to modify push notifications.

Few days ago, some of our clients and few (not all) internal PC are get stucked on a PR_CONNECT_RESET_ERROR on our website. Only on 117 windows version (118 developer version and 119 nightly seems ok). We tried to repair firefox, it works on 95% but we can't ask our client to do this. It works on Chrome & Edge.

We running out of ideas : - we only accept TLS 1.2 / 1.3 - checking CSP - Both IIS and Apache are not working - Firewall are not blocking

I downloaded the new Thunderbird version today and my mail folders are gone. Clicking on the mail icon does nothing. I've checked view-all folders. Nothing. It's automatically downloading email, but I can't see what it's downloaded. Luckily, I can still get into my address book. Also, luckily, I have web access to my six accounts, but I have to check each separately. Help!

For a few weeks now, Firefox has been often freezing a webpage for 5-10 seconds during browsing. It mostly happens when going back to the previous page, but also when clicking a link or doing a google search. For those 10 seconds, you can't do anything on the page; no clicking other links or selecting text.

I've already tried: - troubleshoot mode; it still happens when all extensions are turned off - turning on/off hardware acceleration - creating new places databes - updating to the newest version

What can i do to fix this?

When i go to google.com and enter search query the tab "hangs" for about 10 seconds before the next page starts to load Same issue on 2 separate machines (1 intel laptop, 1 amd pc) both on newly installed windows 11 pro

what i've tried: safe mode, disabling hardware acceleration, disabling antivirus (kaspersky, without any browser plugins or safe browsing) , but the issue persists

Congratulations, between the latest Firefox patch and the gad awful 115 Thunderbird, I can no longer access ANY of my emails, current incoming ones or old saved ones nor my calendar. So, now I will be unable to do my job or attend my various meetings. AND I DIDN'T EVEN GET AN OPTION TO SAY YES OR NO OR BACKUP MY PROFILE. XXXXX [edited for language]

I just automatically updated my Thunderbird installation. Only after the update was I told that the ImportExportTools NG incompatible with the new version. One of the reasons for using T'bird is for archiving old messages (mainly gmail). Are there plans to update the add-on or is there a work around for importing .mbox files ?

I have 2 mail accounts synced to TB. Both are hotmail accounts. I can send emails from 1 but not the other after updating TB from 102.15 to 115.2. Everything else seems to work. I've changed no settings and they seem correct as far as I can tell. When I try to send mail from the problem account, a blank browser pop-up comes for a few seconds (authentication?) then disappears; then, the "sending" bubble comes up and then times out giving this error message: "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.office365.com timed out. Try again." What is a solution for this? Thanks in advance.

This is the same problem listed below. Recently upgraded to Ubuntu 22.04.3 LTS and Firefox 117.0 a few weeks ago and can't get the files to attach. In fact it won't open the file system. Tried removing all extensions as suggested and rebooting, but nothing changed.

This problem began suddenly yesterday. Thunderbird is set to download messages automatically. When I opened it up yesterday, 8/27/2023, it said "downloading 1 of 50". I waited and it just stopped, no error message and no mail came in. Repeated attempts resulted in the same outcome. I reset TB, reset the PC with the same result. I turned the computer off overnight hoping for a better tomorrow and the same thing is happening now, except that it says "downloading 1 of 193". The last e-mail messages appear to have been downloaded on 8/26/2023, in the afternoon. No settings were changed prior to this problem popping up. I don't know whether TB did some sort of automatic update and I'm not sure how I would discover that anyway. An outgoing test message from this account to another account did arrive, although slowly. I'm running TB 102.14.0 (32-bit) on an up-to-date Windows 10. Does this problem sound familiar, and is there a simple fix? The mail is on the server and on my phone as well. I use POP and have not had any problems receiving mail on both my iPhone and my PC. Thanks.

I installed the new 115.0.1 version of Thunderbird, recommended in Flathub/Flatpak version. The issue is that when I launch this version of Thunderbird I lose my account information and am invited to configure an existing email address, which means I lose all my profile. Back to version 1020 in Deb version everything is fine, my profile is intact. How should I proceed?

Playing media volume is low. In-page volume is maxed (eg. YouTube video controls). OS Master volume is maxed.

But the volume of the Firefox in Windows Volume Mixer is a fragment of the volume set. If I adjust it to max, it jumps to a fragment of it. If I adjust it to lower, it gets even lower, like a percentage of what I actually set. The level I actually set gets a grayed out slider button, and the actual slider button slides to this lower level. See the screenshot in the attachment.

It may sound like an OS issue, but as I understand, this is the output level set by the application (Firefox, in this case). Rebooting the OS doesn't help.

Sometimes when I click full-screen on a video, the app view disappears, and I am back out on the home screen. I still hear the video, and can switch back to Firefox and try full-screen again. It usually (maybe always) works the second time.

When it happens, I can briefly see the video go full-screen and rotate to landscape. When the view has disappeared the screen rotates back to portrait. Whenever a video stays in portrait mode when going full-screen, the problem does not occur.

Even when closing firefox, I can still hear the video. So I think it is related to this issue: [https://support.mozilla.org/en-US/que.../1420245]

What I have tried:

• Switching versions of firefox, they all have the same issue; Firefox, Firefox Nightly, and Fennec.

• Clearing cache and disabling add-ons has not worked, but seemed to make it happen less frequently for a while (not sure).

• I tried activating automatic screen rotation, but this made the problem worse. It would then not work the second time and firefox would only display part of the website in the top right corner of the screen. Closing it and re-opening it multiple times did not work. I had to turn auto-rotate back off.

• I'm using the KISS launcher. Tried switching to various other launchers, but it made no difference.

Hello, my name is Eldon Zerr. I have been using my gmail email through mozzila and thunderbird for many years. But suddenly it is not letting me log into my gmail through Mozilla and is giving me an "error 400" . I can get all my emails on the iphone, but not my Mac in the office. Can you [please help me get back up and running? Thank you, Eldon

Up until Firefox 116, Reopen Closed Tab (Ctrl+Shift+T) would reopen closed tabs, and Reopen Closed Window (Ctrl+Shift+N) would reopen closed windows. There was a clear bifurcation, so I could freely close windows and not worry about it polluting my tab history in another window.

The latest change has thrown out that advantage, and now Reopen Closed Tab reopens both tabs and windows, while Reopen Closed Window still just reopens windows. This makes the later essentially useless and the former much more difficult to use for me.

I assume this was done to just continue copying Chrome in all respects since that's how it handles it, but the changelog just vaguely states, "This change is in anticipation of upcoming changes to recently closed tabs."

Does anyone know if there's a setting to separate the two functions again?

I am running Firefox (Flatpak) on Debian 12 and I use a Nelko thermal label printer. I had installed nelko-printer-driver previously and had no issues printing on Firefox but, due to an issue with Debian, I had to reinstall Debian 12. Now, when I try to print a document then Firefox immediately crashes. I have tried:

• Uninstalling the Flatpak and deleting app data
• Help > More Troubleshooting... > Clear Saved Print Settings
• about:config > Reset modified printer settings
• Uninstalled/reinstalled nelko-printer-driver
• Restarted

I've searched the knowledge base already, and can't quite find the answer to my question.

I use Thunderbird 115.1.0 on Windows. My eyesight isn't the best, so I've had to set the font larger. But I can't find any way to increase the height of the rows; that is, the space between messages on the list. There used to be a "row height" among the config options; I can't find that now -- or perhaps it is called something else.

I support Thunderbird and have used it for years -- but I'm older now, and can't see as well. I can't continue to use Thunderbird if there's no way to adjust the height of the rows.

I'm familiar enough with CSS to create a userChrome.css file; I just need to know the exact code to include.

Thank you.

My Firefox is having some problems relating to audio.

If I open a YouTube video, the image will play but there's no sound, on Twitter also, and so on. On YouTube Music the player won't even start, giving the error "An error occurred. Please try again later." I noticed that the stereo icon that shows up in the tab, which allow you to mute the tab, won't show up when I'm playing a video on YouTube, Twitter, Vimeo, and so on.

Only Firefox has no sound, it's not muted in the Volume Mixer, neither in the app volume settings in Windows. I've followed everything suggested here here and here.

I think the problems may have started after I reinstalled my graphic card driver, but I'm not sure since I don't use this computer very often. I have a Windows 10 and my graphic card is a Nvidia GT 630, and the driver version is 474.44.

I use Thunderbird 115.1.0. "Show only display name for people in my address book" is not selected in the preferences. The "Full Address column" Add-on does not work with version 115.*

In all folders the names of message senders/recipients are displayed instead of the e-mail addresses. For example, it shows "My Name" in the outbox - not name@example.org, my@name.com etc. In the inbox, it is "Anna Bel" and "Zack Miller" instead of "support@mozilla.org".

I am not interested in the names. When I want to see those, I look into the mail. I need the mail addresses!

How do I get back the addresses? (I think Netscape Mail did have that feature.)

The chosen answer to a similar question, "use Full Address column Add-on", does not work for Thunderbird 115.* and up.
