I get PR_END_OF_FILE_ERROR when trying to load certain websites. I don't use any proxy or VPN, I tried disabling DoH. Also sometimes i get 403 forbidden cloudflare.

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?

How can I restore Thunderbird settings and/or emails that were lost in the upgrade to version 128.2 (for Ubuntu)? Files for the previous version are still in the hidden .thunderbird folder on my hard disc, but the new version won't recognise them (even if I move them into the snap/thunderbird folder. I have an email backup, but version 128.2 doesn't seem to have a way to restore backed-up emails.

Hy, after the last update the emails I marked them with tags are no more in colors (title, sender etc...). I have no addons in my Thunderbird. I have tried suggested solutions I have read (restard in safe mode, clear cache, disable addons etc...).

Thank you for your help!!

Microsoft are again complaining about normal password login.

Today I have updated to Version 128.2.0esr (64-bit)

I have set outgoing server to StartTLS and OAuth2 and it is fine.

When i set OAuth2 in server settings and try to retrieve mail i get "Host contacted, sending login............" and it sticks at that point with no error messages from Thunderbird or Microsoft.

If i revert to "Normal Password" it is fine.

When microsoft first complained i turned on two step authorisation and the used their option (cannot remember what it was called now) to create a login password/key for thunderbird so that it would still work for "Normal Password" setting

How do we get round Microsoft's obstacles???>

I'm running for quite a time Thunderbird on Windows up to Win11 without any problem. For about 3 years I'm using the same TB profile in dual boot environment with Linux Mint (v21 until last week and now version 22). I understood why I didn't get access from Linux side after the latest TB update in Windows as obviously the file structure and other things had changed to make it incompatible to elder versions.

However, as Linux is now my normal working environment, I've tried it again after upgraded my system to Linux Mint 22 Cinnamon 6.2.9 , kernel 6.8.0-44-generic and failed again, having the same error message when starting the profile: "Thunderbird is already running, but not responding. To use Thunderbird, you must first close the existing process, restart your device, ore use a different profile. "sudo killall Thunderbird" didn't find a running process.

I've tried importing everything in a new profile, which worked (more or less), but failed with all attempts getting access to my local profile. A local profile appears after importing but contains no data, trying to import its data separately doesn't trigger any error message when just ticking "E-Mail", but nothing is imported. When ticking "E-Mail" and "Settings", I'm getting a red alert that asks me to look into the error console which doesn't help either.

What can I do ????

I tried downloading Firefox again and I still can't open it. There must be something in my computer (Windows 11) that is stopping it from opening. It is the browser that I prefer. I have used it for many years and everything is on it. Please help.

How to merge two different sets of Firefox bookmarks simultaneously popping-up 2 different Firefox web-pages into a single Firefox browser system? Please help and advise. Many thanks.

First I'm living in Munich (Germany) and my English - how to say it - could be better. Therefore forgive my mistakes.

I installed Thunderbird 128.2.0esr (64 bit, German language) on Windows 10 to check it out as an alternative to MS Outlook. So far I like what I see and I will probably switch.

One small thing is the column picker button on the right side of the message list pane. I assume - after setting up Thunderbird - it will be rarely used - there is also the alternative by using the right mouse button on any of the columns - but it takes column space. Is it possible to hide/remove the column picker?

In my humble opinion above - next to "display options for message list pane" - would be a better place.

Thank you very much, Reinhard

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.

Morning everyone. For the last couple of days, I've been unable to download emails through TB. I have quite a few email accounts and not one of them is downloading, they all stopped working at the same time. I've checked the OAuth2 settings and everything is in order. I recently removed all the accounts from TB and re-added them one by one to ensure they were set up correctly as I'd been having problems.

Does anyone have any ideas please?

Until today it worked fine. But now whenever I try to login to Xfinity I get You don't have permission to access "http://login.xfinity.com/login" on this server. It works fine on Chrome and Edge. I have disabled my add-ons. I have cleared cache, cookies, etc. I have rebooted. I have turned off firewall. I have checked my DNS. I have changed the DNS protection to OFF in Firefox. I have checked my proxy setting (I have no proxy). I have reinstalled Firefox. Etc. Etc. Nothing works. The fact that it works on Chrome and Edge, that it has worked everyday until today gets me confused. I also tried using my mobile phone as a hot spot to make sure it wasn't related to my Internet connection or IP address. Anyone have any ideas?

Hello, I'm having some problems with multiple websites at the moment on log in, when i put my personal information and click on the logging button, nothing happens, and i have tried with another browse (chrome), the next action is show a captcha to permit the log in, that can't be shown on Firefox.

Some sites are Coursera, this is where i recognized this problem, the other is Good Smile Company (the US version).

Can anybody know how to solve this? i want to stay on Firefox for all my internet navigation.

Thank you in advance.

I reinstalled windows on my PC. I had to password reset because I forgot it and then it made my login back on my phone. I go through the login process on my phone and I first get my Email verification then I get my Auth app and it tells me it was logged in, but doesn't actually log me in. It does this both on my phone and PC now so I am trying to get logged in on my phone to be able to bring my bookmarks over.

I have six windows that I use the most. Sometimes I open more windows, but before quitting Firefox, I close windows that are outside of the first six. But if I don’t close the additional windows, the next time I open Firefox, they are all the same position as they were when I closed Firefox.

And that is good.

The problem is, with the taskbar locked, while using Firefox and using Windows the way it’s intended- opening, closing and switching different windows as I need them, the six windows in Firefox switch positions. The windows shift positions so that 6 is 5 and 5 is 6 and 3 is 2 and 1 is 3 and so on. It’s all random.

So why do the windows shift positions?

It is a hassle to have to keep lining them up again and again throughout the day, so that they are always in the right place so that I don’t have to click each taskbar item to find out which window it is. If they remain in the correct order, I have no trouble or wasted time looking for the window I need to use.

The shifting Firefox windows at random is the problem. That is what this inquiry is about.

Here is a temporary fix without having to set them all up from scratch. It takes a few manipulations, but still better than remembering all the tabs in each window then opening each window and tab one at a time in the order I prefer them to be in. I use an addon called Tab Session Manager. This is not an advertisement for the addon. It is necessary to mention it in case others have the same “switching” windows problems. The addon allows you to save each window, then open each of the saved windows in the proper order.

The things I’m trying to get an answer to, are the following questions:

1. Why do the Firefox windows switch positions? 2. And how do I stop it from happening again?

Any help or direction will be appreciated. Thanks.
