"cannot truely say those downloaded emails are an independent copy because... display whatever is held on server"

Seems to say that TB displays [a message that had been downloaded] not by reading it from folder in computer, instead by reading it from sever. If something different is meant, then please clarify.

So I'm not sure how to search this, I couldn't find anything after trying...so apologies as I'm sure this is covered somewhere. Anyway, when I wake computer from sleep, Firefox is often unresponsive while disk activity is maxed - so I think what's happening is it's storing pages/tabs to disk and reloading them (slowww*) vs just getting them fresh from the web.

If I have diagnosed this right, is there a setting that can be changed to disable this?

(I already tried browser.cache.disk.enable -> false - this had no effect).

Thanks in advance.

• Yes this is an old drive not SSD but for crying out loud I shouldn't have to upgrade hardware for this, in theory at least....

Hiya, I want to add my work account to thunderbird but it requires me to sign in via SSO (had to add the Microsoft SSO extension to chrome to make it work there).

The thunderbird browser cannot do this and cannot see any way to use chrome instead. It looks like setting up an 'app password' as some suggested online has been disabled as the option does not exist for me.

What options are there?

so I am working through downloading python and chromedriver and dealing with PATH issues re: selenium, pip, etc when I start getting first an email error message:

Thunderbird is already running, but is not responding. The old Thunderbird process must be closed to open a new window.

I do not have thunderbird open. i confirm in task manager. don't think anything of it. then firefox starts doing the same thing.

at this point, I am already uninstalling the other software above to try a new, clean install and I am required to restart.

after restart, weird stuff. half my desktop icons and explore files are now faded. neither TB or FF will work. I use chrome, see a bunch of the messages on here to first look at uninstalling and reinstall. Do it. Doesn't work. Next step - run down through appdata, roaming, etc to get to the profiles folders and delete the "profile.lock" file

Yes. This works for FF but WTH!!! I open TB and every email is gone. I go thru the process to zip my profile and import. Nope. Doesn't work. So i unzip the file into a thumbdrive and import using eml method.

TB does not keep my original format, duplicates all folders, and anything older than early 2023 is there but there is no longer a subject, sender, etc

I take a break. Today I am back at it. I cannot access new emails at all. I cannot delete the folders so I make a backup folder, uninstall and reinstall TB and the same thing.

How can I reset TB, import the old emails?

What is the importance if anything of profile.lock?

Any thoughts if working through issues on python, etc caused this?

Hi! I can't see the article txt here https://www.musicbusinessworldwide.com/us-music-publishing-revenue-jumped-10-7-to-6-2bn-in-2023-outstripping-recorded-musics-growth-in-percentage-terms/

I can see the headline. See attached. No issue if I moved to Edge, and I've cleared my cache and data.

Thank you!

Hello: Passwords from CSV file: "firefox logins.csv" does NOT show up in the "Import Browser Data" box? I reinstalled a fresh copy of Windows7 and firefox (Firefox Setup 115.14.0esr.exe).

How than can I import this .csv file? Regards -mdc

Hello,

Every time I end my work and close thunderbird - my e mail accounts dissapear (they are deleted). When I open thunderbird again I have no email, nothing. Everytime I am forced to do all settings from scratch - to configure everything from the begging. Please help.

Hi there,

So, I have a professional account with outlook.office365.com for my professional email (which is aleclercq@sobemab.fr). But I use my personal email to contact you right now. We have Black in Mail operating for all new email and then I can't get email from you unless you authenticate yourself.

Anyway, my configuration is : HP computer, windows 11 Professional (build 22631.4112) Thunderbird version 128.2.0esr (64-bit). Add-on Owl for exchange.

Now, when I launch Thunderbird, it connect properly and I do receive emails. All good.

But the problem comes when I want to SEND an email. It doesn' t work. I have attached some screenshots for you to see. It will be easier that way, I guess. I'll appreciate your help on that matter ASAP. Outlook is ok, but I can't stand it and I really want to use Thunderbird. :)

Thank you Best Regards Alexandre

Ever since I upgraded to 115.10.1 (from a much earlier version, which worked well), Thunderbird is randomly very slow.

First off, at opening time, it takes ages (over a minute) to download some incoming (small) messages - while this was definitely not the case with the previous version I was running. Sometimes, it hangs (for anywhere from 15 to 60 seconds) while I am typing a message.

Also, e.g. today, I tried to send an email (250 KB or so): it just kept on saying "sending". When I clicked (after a few minutes) to stop the sending, the window closed without further ado and I couldn't find the message anywhere (not in the Drafts, not in the Sent). I did it again, it then hung on copying the message to the "sent" folder. When it finally said it failed, and asked if I wanted to have it copied to a local folder, I clicked "yes". Upon checking, it had stored it in the "sent" messages, not locally...

I am running Windows 10 Pro, with ample memory and disk space, and a fiber optics connection. The CPU is not overloaded at all nor any other ressource.

It is becoming increasingly annoying.

Greetngs to all,

                         I'm using Thunderbird Version 128.2.0esr with Windows 11.

I have clicked on View/Folder/Unified Folders but none og my IMAP accounts are listed.

Can anyone please advuise how to resolve this issue?

Thanks,

             Scott

Hello,

I installed Firefox 128.2.0esr. I set the next parameters in GPO for settings DNSOverHTTPS: "DNSOverHTTPS": {

                      "Enabled":  true,

"ProviderURL": "https://safe.dot.dns.yandex.net/dns-query", "Locked": true, "Fallback": true }.

But when checking via https://www.cloudflare.com/ru-ru/ssl/encrypted-sni/#results I get (screenshot in attachment). As you can see from the screenshot, DNS and SNI did not receive the coveted check marks.

Secure DNS We weren’t able to detect whether you were using a DNS resolver over secure transport. Contact your DNS provider or try using 1.1.1.1 for fast & secure DNS. DNSSEC Attackers cannot trick you into visiting a fake website by manipulating DNS responses for domains that are outside their control. TLS 1.3 Nobody snooping on the wire can see the certificate of the website you made a TLS connection to. Secure SNI Anybody listening on the wire can see the exact website you made a TLS connection to.

In my browser / about:config: network.trr.mode = 2 network.trr.uri = https://safe.dot.dns.yandex.net/dns-query

In 128.2.0esr there is no protection against ESNI interceptions and ECH is enabled by default? Or is the problem that the DNS provider does not support the technology from Mozilla? Or what other settings we need use (via GPO)?

Thank you.

Back in the days it was always possible to change Proxy port number (or, I believe, any other numeric value) by moving the mouse scrolling wheel when the cursor is placed inside the related field. I don't know whose intelligent decision it was to disable this functionality, but it has gone since the last update (v130.0). Now the window scrolls regardless of the cursor position. It looks like it works fine, but for those who are used to this kind of functionality, it turns out to be inconvenient.

Please, roll this back before it's too late :) Thank you.

Hi I need to create a filtering rule so that messages with attachments (specifically PDF files) are moved to another folder. I can't find a parameter anywhere that would allow me to create such a filter. Please help. Is this even possible?
