Thunderbird has suddenly stopped pulling in email, please help. It just says 'Checking mail server capabilities'. I have changed no settings at all. Webmail works. Email on my phone works. So it's not the ISP or the server or anything like that. It's just on Thunderbird where I can't do anything, but I've not changed anything so I don't understand.

When I try to send email it fails and says: Sending of the message failed. Unable to communicate securely with peer: requested domain name does not match the server’s certificate. The configuration related to mail.mandyhaggith.net must be corrected.

So please can you tell me how to correct the configuration?

Thank you for any help you can offer.

Best wishes Mandy

I have tried nearly everything on all the forums and help sites to no avail. I still get the error message that my message cannot be sent. Most of the time I get the server response as [C20]: message blocked. I have triple-checked my SMTP server settings and password, uninstalled TB and re-installed. TB seems to have recently changed the profile in use, so it no longer has all the files in Mail\Local Folders it used to have. I'm thinking I need to create a new profile but I don't know how to do that.

I have been reading the NYTimes on Firefox for a long time, but it appears that I got logged out without knowing it. I could not log back in even though I used the correct email address and changed my password twice. I can log in on other browsers using my latest password. I called the Times and the person with whom I spoke, after trying to get me logged in, finally said that this is a known problem with Firefox. He did not have any idea about the cause or what I could do; he simply told me to use another browser. I use Firefox for almost everything and this is, to say the least, an inconvenience--for instance, if the Times sends me a link to an article by Thunderbird (which is my email program), I can't read the article but have to find it on another browser. Are you aware of this problem? Do you have any suggestions for how I might log in despite it? Do you know the cause of the problem and whether Mozilla is trying to fix it?

Versions: Firefox: 127.0 (64-bit) Linux: Ubuntu 22.04.4 LTS

Description: After some time, and (under unknown conditions), the input delay will shoot way up. Like 20-30 seconds.

Strangely enough, this only applies to keyboard inputs. I can change my tab with my mouse, I can click on things, no issues there. But any keyboard interaction is hugely delayed.

This does not fix itself until I close my browser and restart it. Closing the browser is always broken here too, if I close the browser with the [X] exit button, I then need to kill the process because it just hangs. It blanks out the contents of each tab like it's preparing to close them, but it just doesn't ever complete the task without a manual kill.

CPU usage and memory usage are relatively low; significantly below my system's limits.

I've already tried this suggested fix, to no avail.

The frequency of this is only about once a week at most, usually once a month, so it's not a huge issue, but I'm just worried about this occurring during a critical meeting or something later. Having this impending restart needed is kind of worrying for critical usage times.

I'm working on developing a website that uses WebGL in it, but sometimes some bad code will cause WebGL to crash.

I am trying to access websites that use three.js. When I initially start, the website runs too slowly to be usable, but if I tab out for some time and then tab back in, the website runs at normal speed for a bit before slowing down again. I cannot find any solutions to this problem nor anyone else who had the same problem as me.

Hello! A year or two ago I ran into a problem. While Firefox is checking for an update, it does not load any sites. I have to wait about 5 minutes each time before I can start using the browser. It is incredibly annoying. Has anyone encountered this kind of problem?

Thunderbird Email Synching Issue - Replying to email sources data from unrelated, deleted emails. Hosting Comcast dot net

Hello,

My boss, (small family business) insists on using Thunderbird for the business. He sends and receives hundreds of emails every day. Often times has 20+ email tabs open at the same time. It's become such a problem that I have purchase larger SSD drive because he was always running out of storage space on his PC. His Thunderbird file is currently over 12 gig.

The main issue is: He will have several emails open and will start to reply to a customer. When he hits reply, the body of the email references data from an really OLD previous email that was either archived or deleted. Most of the time these are emails that were previously deleted. Then he goes back to his Inbox to try to find the original message and it cannot be found and is missing. He then finds the original email on his iPhone Inbox (Same Email Account - IMAPED to his phone) then forwards it to himself, in order to obtain the original contents of the message again. Sometimes the reply box has data from multiple old emails! It's hard to explain.

This goes on and on and he's driving me nuts, as I'm the local "Mr. IT Fix it." for the company. Although, I have no formal degree or training in such things. My background is in Accounting. LOL

From reading other forums, this appears to be either an IMAP Indexing or Email Deletion Retention policy issue? But it's just really beyond me!

Both myself and a family friend who actually has IT support exp. have told him to stop using Thunderbird for Enterprise use, and migrate to a more appropriate application. But he doesn't want to have to learn anything new or complicated.

Any thoughts, suggestions, other places where I can find a possible solution?

One other thought: This issue does goes go away (albeit Temporary) when I clear his system cache and Force ALL Thunderbird folders to Compact. Thank you!

If the above data is too vague, I can try to provide steps to replicate and screenshots on the next time this happens. Which is often. However, it is almost impossible to replicate on demand.

Additionally - I've read in other forums of similar issues where they were related to indexing and IMAP syncing across multiple devices. One person commented - that it was a deletion retention failure policy within Thunderbird. Something to the effect of, Thunderbird never really deletes emails when you press delete on the desktop application. The email is marked for deletion but all of the email headers and data is still stored in the active cache, or something like that. - And apparently, there is a lag in time that the server or servers update a deletion request if the email is deleted from another app. His primary email host is Comcast.net. So, he's using Comcast Webmail, Thunderbird Desktop, and iPhone 13 mail app. via IMAP, all for the same account that has about 10+gig of stored emails. Oh, he currently has threads turned off by request. Storage cache is currently set to 650mb.

Any help, suggestions or solutions are greatly appreciated. If you have any areas that need clarifying, I would be happy to take screen shots or provide additional data in order to find a valid resolution, as he's not interested in migrating to Outlook or any other Enterprise application.

Thank you!

I'm using Firefox 126.0.1 (64-bit) in Windows 11. I needed to download two files named index.html (in different source directories) from my company's content management system. Both got downloaded as index.htm. They were the right files... only the extension was changed.

I spoke to the person who maintains the content management system. They tested it and said it's not doing that, must be the browser.

That sounds fantastic to me, but I looked through the support messages here and found several about files whose extensions were changed on download; for example from .loa to .mp3. No explanations or workarounds, though.

Can anyone shed light on this?

Good Morning. I have been using Firefox for 20+ years. Last night it did an update overnight, and this morning I am getting "The Page Isn't Redirecting Properly" error message on my business CRM site. This appears to be the only site having an issue. I have never had this error previously.

I tried all suggestions already including clearing cache/cookies, checking settings, delete history, troubleshoot mode and nothing. The site opens fine on Chrome and MS Edge.

Any additional help is appreciated, this is very frustrating.

Thank you.

I can't remember when this problem started, but the volume dips down for maybe 1-2 seconds shortly after the start of anything with sound, like YouTube videos and MP3s embedded in a website. On the same phone with Chrome, the problem does not happen.

Has anyone experienced this? I made a screen capture that demonstrates the problem, alternating first with Chrome, then with Firefox (then both again) -- https://youtu.be/GB116jauaX4

I have 2 soundcards on my iMac, (OS Ventura 13.6.1) : one internal (iMac) and one for music production. (universal audio)

Until the latest update (127), I could select either one and I could hear the audio from Firefox. But... since the update, only the internal iMac audio card is working. Note that I don't have this problem with Safari nor Chrome and it used to work on Firefox until the last update.

Anyone has noticed that? 

Does anyone knows how to contact them and log this as a new bug?

Thanks all!  :)

For a few months now, I have been having issues with Firefox and my computer audio. If I am listening to something, like internet radio (doesn't matter which website), the audio will completely cut out. Sometimes it will start working on its own and other times I either have to force quite Firefox or completely restart my computer. When this happens, no other audio works on my computer. I have had a new motherboard, audio card, speakers all replaced under warranty. I've also re-installed Windows and it still keeps happening. Has anyone else experienced this? Can anyone recommend a solution?

  • This issue significantly impacts the user experience as it disrupts workflow and navigation.

Steps Taken to Resolve:

  • Checked for and installed the latest Firefox updates.
  • Restarted Firefox and the computer.
  • Verified that the taskbar behaves normally with other applications.

Request: Please investigate and address this issue in a future update. Any guidance or interim solutions would be greatly appreciated.

Thank you for your attention to this matter.

Having Firefox open reduces all download speeds, upload unaffected

I have the strangest problem. If Firefox is closed and I do a speedtest in another browser, download a file, or do other internet activity I'm getting about 200-250Mbps d/l and 100Mbps upload. As soon as I open Firefox, whether I load a page or not, the upload speed stays the same, however the download speed drops to about 25-50 Mbps. This only happens on one PC, the upload isn't affected, and resolves itself as soon as Firefox is closed. Here's what I have done without any change in this behaviour;

  • Rebooted
  • ipconfig /release /renew /flushdns
  • Removed and reinstalled the network adapter
  • Enabled, disabled windows auto tuning and tested (slower disabled)
  • Updated Windows
  • Refreshed Firefox
  • Uninstalled Firefox, deleted remaining folders from Appdata (Local, Low, Roaming) as well as the program file directories and "Mozilla" registry entries. Restarted and reinstalled. Issue immediately resumed when Firefox was open.

Also when connected to a VPN Firefox download speed increases to about 60Mbps and is consistent across other software. If I split tunnel another browser outside the VPN, it is still stuck at 60Mbps. If I close Firefox the speed increases.

This makes absolutely no sense to me, so I'm hoping someone can shed some light on this - but it does seem to be something Firefox is doing.

Thanks for any help anyone can provide.

Windows restarted to update and all my 100s of tabs are lost (setting me back days of work!)... Firefox is set to always reopen previous tabs, but it didn't work. Recently closed tabs/windows are blank. The Restore Session page - about:sessionrestore - doesn't restore and lists no previous windows/tabs. I went into my sessionstore-backups folder and grabbed a previous.jsonlz4 that has some data but am not sure what to do with it.

Please help! This is a devastating loss of information, as I use my tabs as a to-do list and had many in-progress projects with resources that I cannot all recover just through history.
