Hello! Since I couldn't find help in the forums, I will create a new question. For about a year now the PC at my work will not open mailto-links correctly. There is no account to select from, the subject has a lock-symbol. The receiver's address is correct though (I replaced it with "address" for the screenshot). This PC is the only one I know with that problem and only with external mailto-links. If I click on an email address inside a mail, it opens it correctly. Thunderbird version 115.11.1 (32-Bit), Win 10

It's pretty impractical, so I am hoping for help. Thank you!

Despite updating to the latest Firefox version (127.0) and performing a reset, I continue to face high CPU usage issues. The battery monitor reports extensive CPU consumption for minimal use, even when only a single tab is open. This problem is not exclusive to the main Firefox app; it persists across other Firefox-based browsers as well.

Device: Xiaomi (HyperOS - Android 14) Issue: High CPU usage across multiple Firefox versions Troubleshooting Done: App reset, tried alternative Firefox-based browsers

I urge the development team to investigate this recurring issue, as it significantly affects the performance and battery life of mobile devices. Your prompt attention to this matter would be greatly appreciated by all users experiencing similar problems.

There are other threads about this, but the solutions given haven't worked for me. I'm using Mullvad VPN, and whenever it's on, I cannot search for anything regardless of my search engine, and pretty much the only website that will open is Tumblr. For anything else, the URL will be in the bar at the top, but it won't do anything beyond that; it won't even show the loading symbol. It worked very briefly when I first got the VPN, but now it doesn't. Other browsers work with my VPN. What am I supposed to do?

I recently installed Firefox and I keep getting crash notices, even when it is not open/running...

I have verified this through the task manager...Nothing named Firefox or Mozilla is running...

I don't have this issue with either Brave or Chrome, and I have, and keep updated ESET software, so I KNOW this is a Firefox issue...

Unless this issue can be corrected, I will have no choice but to uninstall it, as I don't need software that crashes even when it is not being used...

So I've had Thunderbird for a few years. I've always had my (multiple) email accounts set to both check for new messages at startup, and check for new messages every 2 minutes (I keep it open in the background so I can be alerted ASAP). However since the last 2 updates, I can no longer fetch messages either every x minutes, or manually (Get Messages does nothing), and the only way to get new messages is closing and restarting TB completely, defeating the point of having it open in the background.

I've tried: 1) unchecking both 'Check for new messages at startup' and 'Check for new messages every x minutes' = still can't manually pull in mail with Get Messages (the status bar says it's checking, but nothing gets pulled in unless I restart TB)

2) leaving ONLY 'Check for new messages at startup' OR 'Check for new messages every x minutes' selected = nope

3) starting and restarting both TB and my PC = nope

4) checking my antivirus isn't blocking anything = it isn't

5) checking all my email account server settings/passwords are correct = they are

6) testing out Betterbird with the same accounts and seeing if it's still an issue = this also affects Betterbird

7) checking my email accounts are working in other software like Outlook/webmail = they're fine, I can get email there normally

Any ideas as to how to fix this?

Can't use Gmail account anymore have cleared cookie's and caches removed permissions and account from Google and TB uninstalled then reinstalled then add TB account worked for 2 minutes then got the same error also some emails load while others are just a blank screen all windows 10 and TB updates are current Have attached error we are receiving anything else please just ask Any help appreciated

Firefox for Android gets frozen when using it to open large PDF files. I have been meaning to change my default PDF viewer app, but once Firefox has been set as the default PDF viewer for Android, there will no way to change this default; as Firefox default's don't have the option to be deleted through Android's App Info menu.

Name Thunderbird Version 115.12.1 Build ID 20240618125055

IMAP account on HostGator.

In the last 9 months or so, every once in a while (sometimes several times in a row!) when replying to a message, Thunderbird does not set the \Answered flag on the IMAP server.

I enabled IMAP logging and finally caught this happening. The reply is sent and copied to the Sent folder, as it should, but the original email is never flagged as \Answered.

I can't seem to see a pattern why Thunderbird skips this step, occasionally.

Good morning. I have been unable to receive e-mails since 30/05/2024. Has the fact that I received an e-mail message from "Mail@voice" <mboudreaux@firmgroupagency.com> on 31/05/2024, got to do with the problem. I would be grateful could help solve the problem. Thank you. Emyr Davies.

I would like to use Firefox as a browser on my Linux Mint device. As I said in the headline, I have set all languages in the system as well as in Firefox to German and uninstalled and reinstalled the dictionary. So when I write something in Firefox it is underlined in red and when I right click for the context menu where word suggestions are made, only English is displayed and if I then scroll down and want to add another language as a spell checker, Firefox sends me to the add-on administration, which didn't help me. Because no matter what I do, only English (USA) is displayed as the language for spelling. Is there perhaps no way to change this, or is there another method?

Many thanks in advance.

Starting a few months ago Tbird suddenly became noticeably slower, and it's only continued/possibly gotten worse, despite several version updates (which I was hoping would fix it). Currently I'm on version is 115.12.1 (64-bit)

I do have several accounts (all pop) and many folders, but nothing different than before the issue began.

I only have 2 add-ons enabled; Remove Duplicate Messages & SmartTemplates. I've of course disabled them and restarted TBird but it didn't help at all.

I've compacted and repaired all folders.

I've created additional folders to reduce the size of larger folders.

The only thing that helped a bit was troubleshoot mode, which definitely made it a bit better going from email to email and folder to folder, and especially with moving emails from one folder to another (which is usually very, very slow and I see it on the bottom saying "moving email 1 of 10 to folder xyz...moving email 2 of 10 to folder xyz...", even if they are simple/small emails). However, sending emails still took over 5 seconds (see screenshot attached), so that might be a separate issue.

In terms of sending emails, whenever I try to send any email it sits on the sending screen for several seconds or more. My internet is fine (2gb fiber, previously 1gb cable), speed tests max out at the 1gb my laptop can handle. Laptop is 2-3 years old high-end Eluktronics, with no other issues.

Given the above, and that troubleshoot mode did seem to help a bit (but straight out turning off add-ons didn't help), what can I try to adjust (while not in troubleshoot mode)?

Thank you very much!

Hello, I have been using TB for a long time wiht no mayor problem. I recently had a problem with the hosting services of 2-3 of the email addresses I use in TB and when I now open TB I can click once on the pop up (say on cancel), but when the next pop up message appears (with the same message but for another email address) TB freezes.

FF just updated to 127. Every time I open it I get the whole intro shebang about migrating, extensions, etc. When I finally get to "Start Browsing" none of my tabs or bookmarks will load. I have cleared the cache, tried reinstall and no change. What's next, please?

TIA Toby

Im using Ubuntu 22.04 LTS Intel cpu I7 9th gen NVIDIA gpu but i disabled it My problem is that the Picture in Picture mode isnt sticky if i press anything it vanishes from view.

I am using Thunderbird to connect to a personal POP & SMTP server. I have recently migrated to a new desktop and moved the old profile folder to the new computer (so I would keep all the emails). Everything was transferred successfully, including the profile settings.

When I open Thunderbird, I am asked for my password and it all goes well if I enter it manually. If I check the "Use Password Manager to remember this password" box, I am met with a "User to server X with username and password failed" - error and a "Sending of password for user did not succeed" - error. I am entering the exact same password in both cases, yet it only fails when I try to save it.

Hi,

I have been configured my Gmail account in Mozilla thunderbird client version 115.12.0 in Windows 11 system. Have been receiving an error message frequently as below "Unable to write email to the mailbox. Make sure the file system allows you write Privileges, and you have enough disk space to copy the mailbox."

System has enough space and memory and please advise.
