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.

Firefox updated yestarday. I see these changes: extension are gone, theme settings were switched from Dark to Light, "Startup -> Open previous windows and tabs" option went from checked to unchecked. These things are still fine: bookmarks, saved passwords and history. Tried reverting to older Firefox version, but it didn't help so I installed the new one again. I then checked profiles in AppData folder and I see three of them. The problematic one I just described, the one that was automatically created when I tried to downgrade to previous Firefox version and the one which only contains empty "parent.lock" file. There is nothing useful in "Extensions" folders (first profile has addblock extension file which I just installed, second profile has langpack extension file). I don't particularly care about which specific extensions I used since I can just reinstall them when I need them again, but one of those extensions contained custom written scripts which were running on specific sites to help me with my work. Those scripts are what I really want to recover.

Please excuse me if I miss any details.... this is my third time trying to submit this issue.

I will just skip to the meat of it this time. I'm getting this error while working from my localhost. I have been working on a personal project for years with this set up with no issues until today. I can no longer click on the errors in the console log and be directed to the Debugger tab. When I click on errors, nothing happens. If I try to open them in a New Tab, I get the error below:

The address wasn’t understood

Firefox doesn’t know how to open this address, because one of the following protocols (webpack) isn’t associated with any program or is not allowed in this context.

   You might need to install other software to open this address.

I have also noticed firefox does not even load all the files until I refresh it at least twice. Even when it is all loaded properly, the error persists.

I have tried: - restarting firefox - restarting my computer - clearing ALL cache and cookies - running firefox in safe mode - disabling all add ons - disabling performance mode (was already off) - checking network.protocol-handler.external.javascript = false (it is)

Let me know if there is any other information I can provide. I really dislike having to work in chrome for this so I hope I can find a solution as soon as possible.

Hello, I've been using Thunderbird since it first came out may years ago and have been a satisfied user. Sometime in the past year, after one of the Thunderbird updates, Thunderbird became EXTERMELY slow to open. It takes over a minute. I have looked for solutions here for the past year...no luck (I've read through most all of them here, that have to do with slowness of Thunderbird opening, as well as on Reddit). I've tried basic troubleshooting e.g. clearing Thunderbird cache, increasing cache to huge size. I've seen references to the slowness being related to "multiple calendars". I don't use calendars on Thunnderbird and went as far as to delete/disable the default one that was there. Still no improvement. I know its a Thunderbird specific problem since:

a. I don't have this slowness opening any other program on my Mac (opening it or using it) b. I don't have a problem with performance of Thunderbird once it finally opens c. It all started in 2022 immediately after one of the Thunderbird updates.

I am on: Mac Air M1, Ventura 13.2, 16 GB Ram Thunderbird 102.14.0 (64-bit)

I hate to ditch Thunderbird after using it all these years and being a very early user since it came out, but I am at wits end. Any help is appreciated. Thanks for any help in advance!

Firefox can't connect to my local weather station at "http://192.168.33.11:8998/gauges.html" but chrome works just fine.

This is the error message I get:

The connection has timed out -- The server at 192.168.32.11 is taking too long to respond.

Having used Thunderbird for some time, I installed it on a new PC, and found that virtually all my emails on a particular account seem to have been deleted, despite the app being set up to retain them. I checked on the webmail (BT) and they have gone. The account is set up as IMAP - as is another account on the same server, which seems OK. BT won't engage with me on this as they "don't support third party apps" I assume that 3 years worth of important client history is gone for ever? Can anyone suggest what I did wrong, or is this a software failure?

i posted a crash question yesterday and got an email asking me to post these the time is the same i assume because i hit "submit" at the same time for all of them i'm posting blind here because there was no link in the email back to my original post - maybe something else that should be fixed

Slow operation and lockup with some urls that work correctly with chrome.

West Virginia has a website to download old death certificates, but they wont load. There's nothing but a blank page. I'm not positive that it's a Firefox problem, as a friend of mine who uses IE cant load them either, however, she CAN load them on her Tablet. As a historian, I really need to get these records for my research, so I was wondering if someone could go to the site and see of the records appear for them to be downloaded. This is a direct link to one of the records:

link text

While this is the main page were you enter the name you are looking for: link text

If you discover anything, please let me know. Thanks!

I have used TB in Linux Debian for several years. Three days ago it was fine. Now suddenly when I try to get messages from my Hotmail account, I get a black window saying something to the effect that the server may be offline. (It disappears too quick to be able to quote it accurately.) But the messages are downloading OK to my smartphone (not using TB). And I have connected directly to the Microsoft Outlook server, and my Hotmail account is up to date. It seems to be a TB problem! I reset the Hotmail account password in TB as suggested on one of the TB sites, but to no avail. I also disabled my firewall, again to no effect. Please can someone help? (Incidentally, when reseting my Password, I stupidly failed to set the option to record it in the TB Password Manager, so it no longer appears there. I would be grateful also to know if the pw. can be added retrospectively to the PW Manager in TB, and if so how it is done.) Tom.

Hi there, I am getting terribly frustrated, desperately appreciate some help!

For over a week now, I can receive emails just fine, but sending fails completely. It has been working for years, but all of a sudden stopped.

Errors include (see images attached).

Have tried numerous SMTP settings and servers.

Using: Mozilla Thunderbird 52.2.1 (and later version, but rolled back to see if problem got fixed.) Windows7 Pro Avast Antivirus BT Fibre to Home

Any help be greatly appreciated. cheers, Chris

P.S. NOTE: One thing to bear in mind, this did occur at similar time of trying the BETA version on the Outlook Mail Website (But that was on a different PC). Maybe a coincidence, but thought I would mention it anyhow.

Additions: I have tried: • disabling my Antivirus. • rolling back Thunderbird several times to previous versions. • testing port allowance through router.

UPDATE - I have just installed the Outlook App on my android phone, set up my POP account, and IT WORKS both incoming and outgoing! So it looks like it's down to just my PC then.

I get error 5.1.1 when I try to send an email, see below for my my smtp settings and the error msg. To the best of my knowledge I have changed nothing but update to current version. attglobal.net is my email provider, windows 10 build 16299, norton 22.11.2.7, Thunderbird 52.6.0 32 bit,

Suddenly, I could not send emails. This has happened before, but quite some time ago, so I can't recall how I solved it back then. I went through the “Cannot Send Messages” https://support.mozilla.org/en-US/kb/cannot-send-messages steps and discovered that there was no entry line at all for smtp outbound when I checked "Saved Logins" to see the passwords. Mailbox inbound was there, but not smtp outbound. It had been there before without doubt.

The original error message said that I needed to enter a password, which, when I checked as I described, was missing. So trying again, I entered the password and checked the box that lets the system manager remember it. Now an smtp outbound line appeared in "Saved Logins," but I still could not attempt to send a message without an error notice that declared failure

This error message I kept getting was this one:

  Login Failed

  ?  Login to server outbound.att.net failed

  [Retry]     [Enter New Password]     [Cancel]

(As you can see, the underlying email service is from the unfortunate ATT/Yahoo, the second half of which is known by the lovely name "Oath" (visions of writhing fanatics swearing allegiance at a blazing altar), which I am seeking to replace. Meanwhile, I must have working email service from it through the heretofore wonderful client Thunderbird.)

Imagine my surprise when I happened to check the "Sent" box and discovered that these messages all were listed as having gone out despite the failure message I was receiving, but given that tests I sent to myself were not received, these must have been on the order of "false positives." I tried the steps in that "Cannot Send Messages" article and cannot imagine what is wrong.

What am I missing?

Thank you.

Hi folks,

Issue: IMAP folders do not show up in file tree despite being subscribed to AND 'show only subscribed' being unchecked

Scenario: 32bit release channel, issue exists on multiple (all tested) machines, tested with all addons disabled

Long explanation: Been I've been suffering this issue for months hoping updates would fix it. Having searched here thoroughly and found nobody else reporting my issue I wondered if perhaps my configuration had become corrupted across all machines somehow so I nuked the profile and started again from scratch. This solved it so I spent 2 days doing the same to all our other machines. A few days later we were all suffering the same problem all over again. Wondering if it was caused by my mail provider which was AWS I migrated the whole companies mails to Rackspace. This meant recreating all the accounts again and for a few days once again everything seemed fine but then the problem was back across the board. Outlook does not seem to suffer this issue but it lacks many features we use extensively and a number of addons we rely on too.

Please take a look at the attached images; as they say, they tell 1,000 words.... (These are refusing to upload, I shall post and then try to edit this post to add them or post them below, hopefully.)

Any thoughts, suggestions for diagnosing, etc gratefully received!

All the very best, -Tom

Hello,

After upgrading my Thunderbird install to version 60.2.1 on my Xubuntu 18.04 machine, I cannot access my mail anymore, because there seems to be a problem with passwords.

Symptoms:

- When starting Thunderbird, I get an "Enter your password" box for each of my accounts even though I had my passwords saved.

- When I go to Preferences -> Security -> Passwords -> Saved Passwords, the list is empty.

- When I try to enter a password and save it, it does not actually get saved and Thunderbird will ask again soon after.

- The following line is logged to console a whole bunch of times:

JavaScript error: jar:file:///usr/lib/thunderbird/omni.ja!/components/crypto-SDR.js, line 179: NS_ERROR_FAILURE: Couldn't decrypt string

Other findings:

- Downgrading Thunderbird to 52.7.0 fixes the problem. The old saved passwords just reappear again and Thunderbird has no problem logging in.

- Starting Thunderbird 60.2.1 on a Windows 10 box with exactly the same profile folder works fine. It can read the passwords and access my mail accounts.

Can you please tell me what to do to fix this, so I don't need to keep using an old version of Thunderbird just to access my mail?

Thanks,

I've been using Thunderbird for a long time on this computer now and it has always worked like a charm. However, since the latest update I am unable to view my emails as the main window is mostly invisible.

When I start Thunderbird, I can see how it builds the window quickly, displaying one component after another but immediately removing them again afterwards. After this process is over, the window is completely invisible and I only see a small, blue loading circle in the top left of the screen. Clicking on the Thunderbird icon in the taskbar has no effect. Sometimes single, seemingly random elements of the GUI remain visible (like for example single rows of my inbox or the "File" button in the menu bar) but disappear as soon as I point my cursor at them. It is hard to make screenshots of this phenomenon, I would probably have to provide a screen recording from when I start Thunderbird to properly showcase what the problem is. Interestingly I am sometimes able to click onto the menubar options (File, View, ...) and use the context menu, through this I was able to open my address book which functions without any problems.

I feel like the program itself is starting and working as intended, however, the GUI isn't displayed correctly. As I haven't changed any settings in the last days I don't know what causes the problem. Google searches regarding the latest Thunderbird version and known GUI bugs didn't yield any results either.

I use Windows 10 and should be on the latest version of Thunderbird. Any help is very much appreciated!

Similar to the issue described in this thread (https://support.mozilla.org/bm/questions/1240674), I am unable to open Firefox - it simply refuses to open. I've tried multiple times, the option key, and re-installing. Nothing seems to work, which suggests something about my user settings is the issue, but a) I am not keen on deleting this if possible and b) I won't delete my user settings unless that is necessary. Like the attached thread, I am happy to attach crash reports, but without the ability to even open Firefox properly it's not obvious how I do this - force-quitting it just sends a report to Apple.

Any help much appreciated - I'd quite like Firefox working again.

My laptop is a MacBook Pro 13 2020 (Intel) running macOS Monterey (12.7.4). I installed the version of Firefox available for download as of writing (v127.0 based on Finder).

I read through the previous discussion on this issue since I am suffering from the same issue of links not working as expected. I regularly need to forward messages which include links and none of the suggestions mentioned worked for me, and I do not recall this being a problem in the past.

I currently run Thunderbird 115.11.0 on Linux Mint 21.3 Cinnamon & have been using Thunderbird as my primary Email package for many years across multiple computers.

The work around is to to copy any email that is to be forwarded to the Drafts folder. Links are preserved and the message can then be edited as required and sent complete with the embedded links.

Hope this helps others who have the same problem.

I cannot get my emails to print out. This is a new problem as it has worked in the past. The printer is working OK both for photocopies and to print out documents on the computer. It accepts the instruction to print but the paper just feeds through the printer with nothing on it. Help!
