A sidebar has appeared out of nowhere. I removed all extension on that sidebar and it still doesn't go away. I already have a bookmark bar and extensions at the top bar. I don't want another sidebar at every firefox window. How do I remove the sidebar, please.

Came back from an errand earlier this morning and after turning on my Mac again, found that Thunderbird 115.10.1 was prompting me for my username and password at the web page for my account, using a pop-up Safari window. But trying to do that doesn't work because my version of macOS is not supported by Yahoo! Mail anymore.

So I tried deleting the account and adding it back, since this is the very first time it's ever done this, but that doesn't work, either, because Thunderbird still prompts me for the same username and password using the same Safari window that won't work anymore.

Tried updating Thunderbird to 115.16.3, but that makes no difference; still can't send or receive email.

Who's idea was this, and why did nobody consider that web sites have dropped support for many older browsers that can't be upgraded, and give you no option to use a browser of your choice that would work for this, even though it should never be required?

How do I (or others that are affected) solve this problem once and for all?

SENDIN MESSAGE FAILED AN ERROR OCCURRED WHILE SENDINDING MAIL. THE MAIL SERVER RESPONDED; MAIL BOX FULL ... FAILED TO PROCESS MESSAGE DUE TO A PERMANENT EXCEPTION WITH MESSAGE... MICROSOFT UNITED STORAGE IS FULL

Many moons ago I used Microsoft's Outlook as my email program. When I would open Outlook, it would retrieve all of my emails from my ISP's server, permanently removing the emails from the server while downloading them into Outlook.

When I installed Thunderbird recently, it was to do the same thing. My ISP had sent me several notices that my email account was close to full, so I was looking for an email program that worked the same way Outlook does, and removes my emails from my ISP's email server as it downloads them to my PC.

The first issue I'm having is that Thunderbird does not appear to do this? Or do I simply have my Thunderbird account/settings set up incorrectly?

My next issue is directly tied to the first one. Every time I open Thunderbird it starts re-downloading all of the emails that it has previously already copied into my Thunderbird Inbox, but that are still in my email account on my ISP's email server. This is probably 15 years worth of emails and equates to thousands of emails I'm saving, and every time I open Thunderbird it starts re-downloading them again. I simply want to be able to save them to my local email client (Thunderbird) and store them on my PC's hard drive.

The final issue is also tied to the first two: As soon as it starts downloading the emails again, Thunderbird (and only Thunderbird) lags heavily and almost continuously. It lags so badly that it becomes incredibly difficult to write a new email in Thunderbird, and so I end up closing the program and logging into my ISP's email server and using their client to write my emails, or conducting my email business via my phone, which takes longer and is more challenging due to continuous fat-fingering of the phones tiny little keyboard.

So, am I missing something, or do I have some settings in Thunderbird set up incorrectly? Or does Thunderbird simply not work the same way Outlook does (or at least use to)?

Thanks in advance for any help or advice anyone is willing to give.

I was excited to see that Firefox had support for Canadian English, however the dictionary seems to be missing numerous words and I get spelling errors for words like "lasagna."

Is this a bug or is the dictionary just barely populated with words and missing a tremendous amount?

Hi,

Why am I getting this message?

Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox.

I started the program this morning and got a small download. Left the program open and 30 minutes later tried another download. The program shut down last night without a problem. I have compacted the inbox and there is plenty of disk space. What is the problem? Allan

I often receive a 403 error when using Firefox Every time, before this happens, I get the unsafe website warning and then the 403 error when I continue anyway

I am using the latest version at the time of writing These errors only occur on my desktop PC I have tried to replicate this issue on both my phone (Android) and another laptop(Windows 11) but all the websites work normally on there.

I have tried the following, none of which have any effect:

• Clearing cookies
• using Troubleshoot mode
• Restarting
• Changing Useragent
• Using "Forget about this site"

The following do fix the issue

• Using a VPN
• Using Google Chrome
• Running Firefox in another profile

Going through the privacy and security tab and reseting all the settings sometimes works but only temporarily

The following are a few websites where the issue occurs

1. https://kdice.com/
2. https://latinitium.com/
3. https://theysaidso.com/
4. https://opensource.org/
5. httpe://obsidian.rocks/

Well looks like they did it to us again. My tabs are back on top again and need to put them below where I am a lot of other users like our tabs!

Below is my current coding if anyone knows how to adjust it to force the tabs to the bottom again would be much appreciated!!

Current version I am running of FF is 133.0

I've recently been experiencing a new problem with Thunderbird. As soon as I click on a subfolder in the left column that is bolded to indicate the presence of an unread email, the unread email immediately disappears. I can usually find it in either the Junk folder or in Trash. Is this possibly a bug in the latest update?

When the latest version is released, if I continue browsing without pressing the update button, the process suddenly becomes slow or freezes until I restart the device. Why is this? There are no problems until the update arrives, but as soon as the update arrives, the device becomes unstable, and after the update, it works as if nothing happened.

　I am using Google Translate, so the nuances may be different.

I am trying to setup an email account through Spectrum. My user name and password are correct, so I think the problem is in the server settings. Thunderbird has the settings as "mobile.charter.net". I have checked with Spectrum and this is correct. But Thunderbird says that something is still incorrect. Any advice on what I should do?

I've noticed since a few upgraded of Firefox tat I am having an issue loading my local uTorrent GUI at: https://192.168.0.xxx:36724/gui/index.html. I am currently using 132.0.2 x64 and it eventually loads after 3-4 minutes. There are absolutely zero add-ons at the moment, and it does not matter if it is a portable version or standard installed version. I do not seem to have this issue while using Firefox (latest) ESR portable version.

Is there something I'm missing here? I am not sure if it is the port that's the issue with Firefox, because I have a local website using port 9090 and 8080 without any issues on loading. Also, it is happening with the nightly version of FF as well. All other browsers load quickly.

Kind regards,

Hi,

I have a sidebar that appears to be permanent and I cannot make it go away.

I opened firefox, went to reopen the previous session tab with control + shift + t, and my fingers slipped and hit the wrong combo of buttons.

Then this thing appeared. This sidebar. I looked for similar questions on the topic, but it is not the history or bookmarks sidebar that pops up from control + h or control + b. I love hotkeys.

So my question is, how do I disable the dang thing?? I tried going into custom tools, I tried looking into settings, but I really cannot find this. And it seems that other issues are usually to due with bookmarks/history sidebars - which I don't believe to be the issue here..

Any help is greatly appreciated!

It's the sidebar on the left in my image if that provides any further info!

Thanks :)

Hi everyone,

I've been using Thunderbird for a few months now and never had any problems until today when I've updated to 128.5.0esr. I'm using iCloud email and suddenly my Sent folder disappeared. When I started TB it showed up and disappeared after 2-3 seconds. It happened few times when I tried to restart TB however now it's permanently gone. I didn't change any settings and the folder is visible in Apple Mail or Spark, however it's gone from TB. Any idea what's going on? Please help.

Thanks, Szymon.

I just installed Android V 8.1 and the anti-spam function isn't working. Spam mail is not being automatically filtered as it is supposed to do, and does on the desktop version. In addition the junk/spam mail settings that are supposed to be in the Accounts area are not there and the Swipe to Spam function also doesn't work nor does the "long press" to get to the spam marking option.

Any estimate as to when this functionality will be brought online?
