I run a mail server here (VPOP3 as it happens). I have recently changed the HW it runs on to a Win 10 (yeuch!) NUK. All mail works fine except when I try sending emails through it from Thunderbird (latest - 78.6.1 (32-bit)) from a Win 7 (64 bit ) PC. Simple emails or ones with small attachments go fine but over about 200k they timeout. My suspicion is that Micro$oft's Antimalware service is hogging too much of the CPU on the mail sever PC and the send is timing out part way through. I have throttled it back as much as poss with the powershell cmd:- Set-MpPreference -ScanAvgCPULoadFactor and it has improved it in as much as I have increased the size of the file that can be sent. Is there a timeout in Thunderbird I can increase so attacking it from the both ends? I have looked (desperately) for the old advance config but it seems to have disappeared. Any help or suggestions gratefully appreciated. I know I _can_ uninstall the anti-malware but would rather not.

Hi, My E-mail accounts are hosted by Webhostinghub. After years of right work with thunderbird, for some months Thunderbird asked me too frequently to insert my passwords on my mailboxes abd aswered it could not get them form my host etc... Support at Webhostinghub told me to unsinstall Beta version and install the 78 one, what I did. I have lost all my adresses. Maybe they are on my hard disk, somewhere on "thunderbird" throug "app data", but I cant find them at this moment, when I could, they were in an unusual format. Have I to come back to Beta version How ? Thanks. Rgds.

Hi, first of thanks for reading and possibly responding.

The issue I am having has been going on for a few days. In websites where youtube video's are embedded if I try and play the video on the said site it will load and display an error message An error occurred. Please try again later. If I visit the video on youtube, link provided in the video itself, then it plays just fine. Error is not restricted to one site but anything that embeds youtube videos.

I have also come across some strange youtube.com issues, when I am on the main website you get the thumbnails of video's but no time duration are displayed in the thumbnail, neither are the 3 dots where you can have one of the videos removed (not a big deal and maybe this was implemented a while ago I don't know tbh). When I play a video, as in visit the video page on youtube the side bar videos sometimes do and sometimes don't display time duration.

Please check attached image to see what I mean. Left is without said timecodes, right is what it almost should be.

What addons do I use: Ublock Origin is the only one worth noting but even without it the weird thing still occurs. I don't use any plug ins that correspond with youtube.

I am using the latest Firefox on Windows 10.

Things I have tried thus far to resolve it: - make sure Firefox is up to date - try with and without addblocker (Ublock) - remove Adobe flash entirely - refresh Firefox and clear all data and cookies 9tried this I think 3 times now, no change) - looked through older posts with similar issues but most links regarding html5 on youtube were 404 and sometimes the solution stated things like 'cause by some video helped addon' which I do not use or updating Flash

Am I the only one with this issue?

All of a sudden, i noticed a copy of 'Other Bookmarks' on my Bookmarks ToolBar.

It is an exact copy of my Other Bookmarks, located where it normally is. There is no way to delete it, not with right click or from the menu tree. i cannot drag it either. When i reset FireFox, it is gone, but then shows up unexpectedly.

When i hover over Bookmakrs Toolbar, it is not visible (all others are), and when i 'Show AllBookmarks', it is visible, but at the bottom of the list.

Any help would be appreciated.

Hello,

I'm beginner in development. Today I'm working on some CSS files.

But when I reload, the content don't load the new features. I've try to clear cache, remove stockage on the console , and also try command + f5 (on iMac).

The only one solution I've founded is to clear cache , leave firefox , shutdown computer and restart.

Very contraignant. I've test on Chrome and it work well. So I don't know what I need to do to...

I'm using MAMP to lauch app on local

Hello,

my Firefox on Android running on Xiaomi Redmi Note 3 suddenly stopped working after five years. It does not display the content of the web page even though it loads it completely. I can see only blank page. I concluded that the website is fully loaded because on a “blank” page I can tap on any link that is then loaded, but the website still ends up being completely blank.

I tried the following: - clean firefox cahche - reinstall firefox - reboot the phone several times - install other versions of Firefox (nightly, firefox for Android Beta, Quantum)

Nothing helped.

Chrome browser is running normally.

I haven't changed anything from the settings on my mobile phone, nor have I added any new apps. I've had a problem for the last week since, I guess, since the last update was released.

I'm in a bad situation because Firefox is my favorite browser that I use on five devices connected to the cloud.

P.S.

By searching this forum I found that it was some kind of bug in Firefox, but that was more than two years ago and the problem was marked as fixed.

Please help and advice.

Since today I can't access my Yahoo IMAP and SMTP servers, neither with TB 78.4.0 nor TB 68.12.1. The access to Yahoo's POP3 servers is possible as I have still one Yahoo e-mail account which uses POP3 server.

Yahoo had announced that they will restrict the access to their e-mail servers for "outdated Apps", but to Thunderbird this restriction should not apply.

Things I've done so far:

• allowed cookies in "Privacy & Security" (was already set)
• deleted all old passwords
• tried to change authentication method to OAuth2 both on IMAP and SMTP servers, worked for the IMAP servers only

The following errors occur:

• TB just says "Couldn't connect to server imap.mail.yahoo.com", and that's it. No "Enter password for server XYZ" dialog is shown
• I can't change the authentication method for SMTP servers to "OAuth2", the option is not shown in the drop down list
• since one of my Yahoo e-mail accounts (which is accessable via POP3) is working with TB, I've tried to access my other Yahoo accounts via POP3 servers instead of IMAP servers, but failed

I would be grateful for any help and ideas.

Starting today, Google Calendar will not load. There is none of my data in it. I cannot navigate. This is only in Firefox. A blue color streams across the top of the screen as if it is trying to load.

I have upgraded windows 7 to windows 10 Pro. My imported address book shows rows of what would look like a little head and body. If I double click I can read the addresses ok. How can I correct this?

The addresses have been imported ok

On my laptop (Macbook Pro 2020; macOS 10.15.7), in Thunderbird (78.6.1; 64-bit), within only one email account (IMAP; server type = owl), the messages I see in every folder for that account disappear every time Thunderbird checks for new messages. (I have changed the time value to verify this.) This of course just started happening today, has worked fine for many months before this (even last night), and I recall no changes having been made to trigger this.

I can see the messages in any given folder again "if" I click on another folder and then back on that original folder. It is as if Thunderbird is forced to reload/re-show them. Or, I can right click on any folder, choose Properties and then click Repair Folder. This, too will restore visibility to the messages, until Thunderbird checks for new messages; whereupon, they all disappear again.

In order to give you wonderfully helpful people more information, just in case...

• I did add this email account in Thunderbird using the Owl for Exchange extension, which has worked great. I do not know if it may be the culprit. Restarting Thunderbird in Safe Mode cannot verify this operation since the account is not even available when doing so.
• I have multiple email accounts created in Thunderbird, even other IMAP accounts, and this only happens with one account.
• This same problem email account does not have issues online or through my phone.
• I noticed that this problem email account is the only one that will not allow me to Compact Folders. That option is greyed out for some reason.
• If I have unread messages in my Inbox, then the Inbox folder still indicates as much, even though the messages are not visible until I re-jog things.

I am currently out of ideas.

It's been a while since I noticed Firefox video is laggy on every website. I thought it was about some driver problem but everything else seemed to work well. I downloaded Chrome and it didn't have any problem running any video.

I tried clearing Firefox's cache and I tried to "refresh Firefox" on about::config, but it didn't work. I don't have any missing system updates, I'm running Firefox 84.0.2-1.fc33 on Fedora Workstation 33.

I don't like using Chrome so your help will be really appreciated.

Thanks in advance!

I have the password registered in lockwise for https://www.sciencedirect.com/ but it doesn't work when you enter the site?

Using live server on visual studio code (127:0:0.1:80). The minute i click it, pop up with mozilla crash report shows up. Not sure as to why it is happening. Live server settings has been done accordingly. it would be of great help if this is sorted.

Firefox slows down or even freezes for a longer time when I am typing in text in forms (like new GMAIL messages, search boxes, etc). Especially when I make mistakes and delete some.

I have Refreshed Firefox and removed the Adblocker add-on, which I thought might cause the problem, but the problem persists.

Any idea how to tackle this?

OS = Windows 7 (64 bit) Browser = Firefox version 84.0.2 (32-bit) Thunderbird = Thunderbird version 68.8.1 (32-bit) Synchronization software = Microsoft SyncToy version 2.1 (64 bit) External hard drives = Samsung 5 TByte

My normal procedure for keeping my three (3) computers synchronized is to run SyncToy at least once a week. That puts the latest version of any piece of data on all three computers. I then synchronize my main computer to three (3) 5 TByte external hard drives.

SyncToy is known to screw up when it cannot determine which data file is the newest by the file date in it's cache file (a Microsoft .dat file.) I end up with test.txt and test.1.txt on some hard drives as a result.

This past week I discovered my Thunderbird directory/folder increased in size tremendously. Numerous files in the directories/folders cache2 & cache2\entries have two (2) files with the same name except for one (1) of each file has a .1 on the end. The size of the files seem to be identical.

Example: 0710D3592D67032272A741CF6F0F4734A5F29E16 0710D3592D67032272A741CF6F0F4734A5F29E16.1

Before I delete the files with the .1 extension (hundreds and hundreds of files) I am asking if this is a SyncToy screw up or is something wrong with Thunderbird.

Any help would be appreciated.

Thunderbird has stopped saving drafts either on its own after (n) minutes of inactivity but also whan I press CtrlS In afct I cannot even move a message by dragging it into it

I pruned the drafts mailbox (deleted some old messages) in case that's it. No luck. I just see "copying message to drafts folder", the progress bar looks full (100%) but the highlight still moves from L to R (image) I repaired the drafts mailbox - no luck Stuck now, ideas please. Win 10 64. up to date TB

I just installed Thunderbird recently, went through some hoops to get my two Gmail accounts receiving mail. when i went to send an email from one of them: SMTP timeout error. thought id test by sending some test emails to my other accounts: timeout error, thought it was something wrong with my Gmail settings.

Out of curiosity tried to send an email from my outlook account to my gmail accounts, same SMTP error.

Went to troubleshoot, double-checked all my SMTP setting for all my accounts, tried deactivating my firewall, safe mode with internet won't let me use Wi-Fi (I'm on a laptop with no wired connection available), tried setting min TLS version to 1. SMTP timeout error

what am i missing?

This issue has been around for months, if not years. See e.g.:

https://support.mozilla.org/en-US/questions/1289060

This happens even in Safe Mode with all add-ons disabled.

Previously suggested fixes such as the following don't work anymore: - specifying a default account in Account Settings; - going to Server Settings > Message Storage > Advanced and checking "Include this server when getting new mail"; - playing around with the parameters of the Manually Sort Folders add-on.

Ideas, anyone?

I just formatted and installed Windows 10 (Pro N, 64-bit, 1909 update) and then installed firefox.

To my surprise, no videos can be played on any website (except youtube).

The video either doesn't load or shows the "Error loading player: No playable sources found" error.

I had no extensions installed, tried refreshing, tried disabling hardware acceleration; nothing solved it.

All content plays fine on chrome.
