About once per week, I'll be using Firefox and it will stop working. I'll close it and open it again and it gives me an error message "The application "Firefox" can't be opened."

If I download Firefox and reinstall it, everything will work fine for another week and then it will do it again. I'm not doing the same thing when it breaks. It does it on both my Mac Mini (macOS 14.5) and my Mac laptop (macOS 12.7.5).

It just started happening in May on both. Nothing has changed on both that I can think of.

Hello! We are a real dues-paying member, having made a number of donations over the years. We have been having trouble with emails received from Microsoft-based systems, with the HTML formatting of messages getting lost and the attachment of a winmail.dat file, which we can't open. We tried to use your Lookout add-on, but with all of the permissions that must be given in order to use that add-on, it will not pass our IT security folks. Is there any chance you will be able to improve Thunderbird to read those messages without having to use the add-on? We really hate Microsoft, and would prefer to stay on your team, but we will not be able to unless a solution can be found.

Thanks! Mark

Despite literally hours of frustrating -- now infuriating -- effort, my inbox won't show "from," which was removed by the most recent update. Is this problem fixable? If so, how? (If not, I'm damn well going to dump Thunderbird.)

We have recently moved to a new mail server. We currently have about 20 Thunderbird email clients on Windows in an office location and a macOS home machine. On all machines email is configured to use IMAP on hostname.com port 993 SSL/TLS with Normal Password and SMTP on hostname.com port 465 SSL/TLS with Normal Password.

The home machine is working 100% with no issues, it does have a much faster and lower latency internet connection than the office machines.

Many of the office machines are experiencing intermitent SMTP error messages when sending, intermitent, "unable to save mail in the Sent folder of the Inbox", messages and intermitent unable to move messages between folders.

I have checked and double checked the settings on affected machines - however, I believe a settings issue would result in nothing working, not intermitent functionality. Plus all is working fine on the home machine with the same settings (different OS, but ports and security settings all dictated by server).

With one client behaving properly, the server likwise behaving properly when addressed by the working client and the intermitent nature of the problems we are finding, I suspect we have some sort of network issue. Somthing timing out or a firewall/AV software causing a delay.

I have increased mailnews.tcptimeout on affected machines to 250 based on a forum article but this has had no effect (No idea of units here but if it is seconde then I am not supprised - the SMTP errors, when they happen are almost instantanious).

Any ideas on how to trobleshoot this problem further - The problem seems to get worse through the day, although that may just be peoples tollerance of an intermitent issue going down.

In the past, I could click on an email address and drag it into a new subfolder I'd made (let's say for emails to a group about baking). Easy as pie!

Sorry for the bad pun.

Now, when I try to click and drag, it will NOT go into that subfolder. I looked in Help and there were answers about csv files, about a horizontal or vertical view, etc. None of that made sense to me.

So I'm wondering if it's still somehow an easy thing to do, to duplicate someone's email in one or more other folders. It seems like it should be! Thanks, Su

At our clinic when we cannot answer client calls it goes to voicemail. The voicemail the should be sent to our email and transcribed, however it hasn’t been. It leaves us with the only option to play voicemails aloud while clients are going in and out of the lobby, which we find unprofessional. Please help us fix this!

So, this is going to be an incredibly weird question, but is anyone else having this issue? As of about two days ago, any time I try and load a video on youtube it will refuse to load for upwards of 30 seconds, however if I toggle the new stable volume option off/on it instantly loads. It will then play for about 2-3 minutes or more depending on video length (sometimes way more) before the buffer bar will stop entirely, take over two minutes to load the video again, then keep playing. More often than not doing this multiple times per singular video. Often times it won't even load anymore at all and I am forced to refresh the page and toggle the stable volume once again.

I've tried disabling every single extension I have, including ad blockers, restarting the entire browser, and using a different account, and it still happens no matter what. However it is not an issue that occurs on chrome or edge, so I'm at a complete loss of what is causing this. Looking up this issue comes up with next to no results, so is it possible this is a youtube issue or is something seriously wrong with my browser and I need to re-install it?

I just noticed (after 7 yrs) I have Thunderbird(beta) 32 bit on my laptop windows 10 (64 bit machine) and Thunderbird 64 bit on my desk top Windows 10 (64 bit machine). How do I get the 64 bit Thunderbird on the laptop without loosing all my settings to login to my 4 email accounts?

In my inbox I see a couple of emails that (once opened, or even seeing preview) are not associated correctly to the original email sent or received. It's quite odd as it happened only a couple of times, but even after updating, rebooting and moving these messages, they are still showing the wrong addressee and content.

In the attached screenshot you can see the example. Looking forward to receiving your help. Best regards, Nuno

Greetings, recently our pc was attacked ,malware. A new windows program was installed. This resulted in some apps being deleted. One of which was the Firefox email. Inspite of many attempts to reinstate it I have had no success. There is great difficulty in finding what to do to reinstall. There are assumptions that I have particular information. Other than our 3 email addresses we do have any code numbers or passwords, as these to were also lost. As it has been several days since the "repair" the inability to access Firefox with historic emails is now creating a number of serious issues. I need urgent help in reinstalling our Firefox email. My inability to find that one person who I know can help is out there. The FAQ were of no help. The request how to reinstall Firefox does not appear to be a FAQ. Ross.

I have several g-mail accounts that I used to open on Firefox - until yesterday. Now I'm getting a silly message below:

I'm working on ASUS, on Windows 86bit. If I reboot my PC g-mail works again for a couple of hours. I have no problem accessing my g-mail accounts from Chrome.

Any help? Thank you all Marina

I can no longer use my camera on firefox, firefox displayed some message about camera when we were trying to chat, but I missed it, I have granted relevant permissions on the site, that we use reularly. The camera icon on the address bar appears red, and I noticed that in Windows security, it lists firefox access requests, but shows no way to grant these requests.

I am not tech minded so please if anyone could keep it simple, I would appreciate it.

Often, when I go to history and try to restore session..it is greyed out. it occurs randomly, but It ALWAYS occurs after an update. This is so frustrating! It never happened on Edge or Chrome, not once. I know it might seem Karen-like fuming about it, but when you have dozens of important tabs open and they don't restore you too will become a karen. I'm almost about to uninstall Firefox because of it

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...

I added my own shortcuts and deleted all the preset ones (Wikipedia, Twitter, Amazon etc). On deleting the last one of the default ones, the 'Add a shortcut' button has completely disappeared. Is there another way to create a shortcut?

I am trying to view uploaded videos in to my work portal and when I try to view the video this is the error message I receive. I am running WIndows 10 on my desktop. My Windows is up to date and I have cleared all cookies and still not working. Please help. Thank you

I am using Firefox 127 on Ubuntu.

When I press the Control key, I often lose focus in the window I am currently viewing. This is annoying as it prevents me from copy-pasting for example.

Sometimes the focus is back when I release Control, sometimes it is lost and I have to click again on the text field. It does not happen on all websites, for example support.mozilla.org works well, but it happens on duckduckgo or overleaf.

It does not seem to be the same as existing issues such as [the "show mouse when press Ctrl" of Ubuntu] (it is disabled) or an addon (the problem still happens in safe mode).

In case it is useful, when I press Control the tab bar background goes slightly darker, see attached images.

Thanks for your help :) Nicolas
