I have 3 accounts that are all IMAP accounts to smtp.office365.com. They have worked without issue for years.

Recently, immediately after hitting send, I get:

The message was sent successfully, but could not be copied to your Sent Folder. The message could not be sent because the connection to Outgoing server (SMTP) smtp.office365.com timed out. Try again? Would you like to return to the compose window.

It does not have a delay that would be long enough to have timed out. If I then wait on the message without responding at all, the message goes away as does the compose window.

I also increased the timeout but that did not address the issue.

What might I explore to further troubleshoot/correct?

Sometimes, I have seen these kinds of issues come up with updates of the software and then later resolve, but this one has been persistent and I would like to figure it out.

The emails have worked fine for years and all that are related to office365 from multiple companies and multiple email accounts are having this issue.

I am on the latest TB 32 bit version 91.4.1 running on Windows 10.

Thank you for your guidance.

I booted into safe mode of Firefox and disabled all the extensions. I couldn't even boot the app, but now I can boot without being in safe mode, but if I close a tab, it crashes immediately. Or if I quit the app - it crashes.

How do I keep Firefox from losing the internet connection just cause I don't want to close all the tabs I've had open the past week or so? I've tried clearing the cookies, and then reloading my open tabs, but it ends up losing the connection, just the browser itself. Other browser still works. Completely closing all tabs and restarting Firefox gets it working again, but dare I reload the previous session again, open all the tabs (acts like it's going to work), but then loses connection.

All of a sudden I can no longer access a website that I have visited a million times before. I get an error message stating...

The page isn’t redirecting properly

Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

   This problem can sometimes be caused by disabling or refusing to accept cookies.

I have cleared cookies/cache and all that achieves is that I can get to the website's log in page but then straight back to the same error message. I'm so frustrated as this is a website I need to access for my work.

I can get to it no problem on my phone so it appears to be a Firefox issue. I don't want to use another browser as I get on well with firefox but I fear I may have to as this is too important a website to be without.

Any help would be appreciated - thank you, Nat

Greetings. I can't open most sites I usually visit (even google.com) via my Firefox 98.0a1. This happens since today. All error codes are SEC_ERROR_LIBRARY_FAILURE.

Tried to:

• Disable DNS-over-HTTPS.
• Disable HTTP/3.
• Disable proxy (never had it enabled anyway).
• Disable sending info to Firefox developers.
• Change settings of DNS-over-HTTPS.
• Restart the browser (after each action).

Nothing helps me... But I still can visit some websites, but most common resources are not working for me. Please help me because I can't use Microsoft Edge without getting mentally ill. :/

Somewhen before or with 91.2.1, the default action when opening an existing email became "Edit draft message." (W10 19043, synching to GMail) That setting is nonintuitive and just wrong. A default should NEVER be an action that commits to an irreversable behavior path. Please fix.

This extremely bad design "feature" has apparently been around quite a while and generates exactly the problems returned by a search here on "delete attachments Thunderbird." I first noticed the behavior just about the time GMail introduced two-factor authentication. Maybe no connection there, but ...

Hi,

TB 91.5.0 on Windows 10 (with profile folder excluded from virus scan)

The latest update to seems to have resurrected a problem with saving copies of sent emails. Sending works fine, but copying of the sent email to the sent folder causes the send dialog to hang. Disabling the "Place a copy in:" option in account settings eliminates the problem. Using the "Other" option to place it in a local folder works *that is not part of a unified folder* works OK.

I have tried repairing folders and deleting the sent files inside "smart folders" in the profile, with no luck.

Older details here: https://support.mozilla.org/en-US/questions/1363781

Thunderbird keeps asking me to compact folders, c.f. the attached screenshot. Meanwhile, I also checked the profile files under AppData\Roaming\Thunderbird\Profiles, the whole folder of the profile files has only 24.2 MB (25,477,204 bytes).

I can not get thunderbird to bring over email for 6 days now I get the following error everytime. (Sending of password for user .........................@verizon.net did not succeed. Mail server pop.verizon.net responded: [SYS/TEMP] Server error - Please try again later.) I have tried creating a new password on the server account and restarting thunderbird with the new password . Did not help. Any Suggestions?

Hi, I've recently noticed that Firefox is not using Intel Graphics for hardware video decoding, here are the specifics:

- I tested this on two separate PC - one laptop with dual GPU (an Intel UHD 630 and NVIDIA GTX 1070) and one desktop with dGPU removed (leaving only an Intel UHD 630 by i7-9700K), on both PC I made sure to run Firefox on Intel GPU only. - According to information I gathered online, Intel UHD 630 should support H264 decoding and VP9 decoding without any problem. - I tested videos from Youtube (VP9, non-HDR video) and Twitch (avc/h264 video) - The exact same video, when played on Microsoft Edge (Chromium), uses Intel's hardware decoder without any problem. - On the dual GPU laptop, when being forced to run on NVIDIA's GPU, Firefox correctly uses the NVDEC decoder without any problem. - Both PC uses the latest Intel driver (30.0.101.1191)

I have attached copies from about:support page below.

In Firefox settings, under General -> Performance section, I have left "Use recommended settings" checkbox on.

Could someone help?

Hi. A few weeks ago I had a Thunderbird-is-already-running type message, and couldn't launch Thunderbird. I consulted these forums, and (as suggested) deleted the parentlock file. That got me into Thunderbird, but all Local Folders were missing from my Local Folders list.

I consulted these forums, and (as suggested) deleted .msf files from the Local Folders folder (with Thunderbird closed). I restarted. These files did not regenerated, and the Local Folders are still inaccessible.

I can use the Thunderbird client to search for messages in the Local Folders. I can see these messages, but they cannot be opened.

Each individual Local Folder file seems to be there in the Local Folders folder. I appear to have only one profile.

I would really appreciate your help in reinstating the "missing" Local Folders, which contain (guess what) important e-mails. I've no technical expertise (any longer), so would need really clear instructions to follow.

Big thanks.

On Microsoft Edge, whenever i type the first letter of a word it will suggest automatically the recent words that i have use. How to enable it on Firefox, i already browse the settings? I really need it on my job specially doing reports. We can only use Firefox to access our websites.

Using TB v91.5.1 on Windows 10 x-64. I have several mail accounts, one of which is for a hotmail.com address. This has been working fine for years, but over the past couple of days, I don't seem to be able to send emails form this account. I can receive them fine, but when I try to send, I get the small pop-up telling me it's sending the message, and the progress bar is at 100%, but it doesn't send the message, it just sits there.

I looked in the error console, but nothing was added when I tried sending.

You can see my server settings for the account in the attached image.

Any ideas? Please let me know if there is any other info you need.

Thanks

I cannot watch a video on youtube when it is in the process of being live streamed. I remember a time when I was able to, years ago, but I can't any longer. I'm not sure what has changed. I found an article that says to install the optional update called "Windows Media Pack" in apps and features, but no app with that name exists. It was only a year old solution, so I'm unsure of what changed so significantly. I just installed another optional windows update, and also updated the browser, but still doesn't work.

Edition Windows 10 Home Version 21H2 Installed on ‎09-‎Jun-‎20 OS build 19044.1466 Experience Windows Feature Experience Pack 120.2212.3920.0

Firefox: 97.0 (64-bit)

Hey folks, hopefully you can help with this mysterious issue!

I've been running Firefox successfully on my Windows 10 PC for a long while now. Last night, for some reason it simply ceased to work. New windows and tabs would not load any content. I also couldn't access the Settings at all (clicking on Settings in the browser menu produces no results or feedback.)

Yesterday, I had Firefox open all day (I usually have my computer on all day), and it was working fine. Around 8 or 9pm, I first noticed that none of my open tabs were loading any content, and the tabs had the "loading" animation playing. New tabs would also not load any content. I assumed it was an internet issue as I did see my internet connection get disrupted once or twice. I did not see anything (apps, etc) on my PC updating.

This morning I found Firefox was still not loading anything, although my internet connection was fine. I tried opening Chrome, and it ran just fine. Everything else that it is internet or cloud based on my PC is running fine too. So it seems to be an issue just with Firefox.

I have listed my steps to troubleshoot below, but I want to note one weird thing I observed: Even when Firefox is closed, and Task Manager doesn't show any Firefox processes open, my PC seems to think Firefox is running. For ex. while trying to uninstall Firefox or delete certain files, I would get a warning to "close Firefox first" or "can't perform this action while app is running." After seeing these, I would again confirm that Firefox appears closed and Task Manager shows no related tasks.

My PC build: - Windows 10 Home, 64 bit - Version 20H2 at start of issue (updated to 21H2 during troubleshooting) - OS build: 19044.1526

Things I have tried for troubleshooting already: - I have WebRoot on my computer due to my job, and I asked our IT staff if they could see WebRoot blocking anything related to Firefox on their end. They said it was not. - Used "Firefox Refresh" - Uninstalled and reinstalled Firefox - Cleared app cache / app data - Updated Windows from 20H2 to 21H2

Note: This message was sent on a different computer & browser

When I display the review page for any installed add-on, I'm unable to submit a review. A few details:

1) I do not see the expected, "Rate Your Experience" link 2) I'm logged onto my Firefox account 3) I'm aware it uses different credentials than Mozilla Support 4) I've tried clicking on the yellow stars but it doesn't allow me to rate the plug in or display any new links 5) I've read other forum posts from other users who've experienced the same symptoms

Ideas, anyone? Thanks,

- Fido

I temporarily logged into customer email account in order to download the mail in it and transfer it to their email at a different webhost.

And in fact subsequent to that the email account was closed at the prior host by its owner. They actually deleted the email account at the old host "Bluehost" which admittedly is a garbage host and hence why they moved.

So I removed it from my email accounts in my Thunderbird.

For some reason since then I have been receiving constant popups from Thunderbird "Authentication Required - Mozilla Thunderbird - https://box2164.bluehost.com:2080 is requesting your username and password. The site says: “Horde DAV Server”"

and the username field has the email address in it. The password field is blank.

And I checked the outgoing mail servers in Thunderbird to confirm I have no connection to the email acct stored in Thunderbird.

Any thoughts on how to alleviate this issue?

Thank you all for your time and attention to this request.

This is happening every few minutes now. It started right after the 97.0.0 update. The 97.0.1 update doesn't seemed to have helped.

I don't use any browser extensions.

I never saw this issue before, and I have been using Firefox as a primary browser for many years. I'm on a MacBook Air, M1.

Please help me remove this blank area section on the web pages. its on all of them on every tab. I have tried restarting and updating. I cant get it to go away.

thank you Mark
