I updated my desktop browser today and now there is an expandable sidebar at the left margin of the window showing tool icons for Tabs from other devices, History and Customize sidebar. I can see how to remove tool icons and how to expand or collapse sidebar but can I remove the sidebar completely? Is this an option? I prefer the old look with the browser web page content extending all the way to the left of the screen, without the narrow vertical sidebar.

TB working fine, then next day opens up as Blank screen and a setup tab Profile shows to be still there as do mail folders .... so need to recreate profile.

Created a new Profile I copied over the folders:

 IMAPmail
 Mail

and the following files

 key3.db
 logins.json
 cert8.db

and all of the pref.js files (1 through to 141)

The profile folder does show new profile active ( as per this pic https://flic.kr/p/2pjRyRz)

I created the 2 IMAP account login details, I now have access to the inbox for 2 IMAP account, but I do not have any the filed mail (local folders) how do I get these back. This is an important item for me as many years of filed emails.

I back up my TB profile every few months. I just went thru the Cox-Yahoo email conversion and I am getting emails. When I did my back up, I noticed in the properties it had one more folder and the files went from 1311 to 2585 files. Is something wrong? Do I need to compare and research what is causing this or just move on!

I've used gmail (with multiple email accounts) on Firefox for many, many years. I switch back and forth between my email accounts daily.

In the past few weeks, though, when I try to switch from my primary account to the others, it just defaults back to the primary. I've purged the cache, I've signed out and signed in. This does not happen on Chrome, just Firefox, which is why I've brought it here.

If I change the URL of the mailbox

https://mail.google.com/mail/u/0/#inbox

to

https://mail.google.com/mail/u/1/#inbox

It will take me to another mailbox. I can then change that number to get to the others. But it shouldn't be that way. So ... what is going on? How do I fix it?

Hello All, I'm new to Thunderbird and here is something I'm wondering about: I created all my accounts and set everything to Unified ... all works fine. All 5 accounts show under "All Folders" ... if it's also checked, but I don't use it usually. In Unified view, however, UNDER the unified folders, my primary account is missing...?!? Again, I'm talking about the account list UNDER the unified folders! ... not the "All Folders" list! (if it's checked) (I usually don't have "All Folders" on)

The drop-down lists of the single unified folders, however, e.g. Inbox, Sent, etc., DO SHOW the primary account! (On a side note: under Drafts only four accounts show ...?)

So, why is the primary account missing in the list UNDER Unified folders ... (there are only four plus "Local Folders") but it is listed in the separate unified folders, if opened..? I hope explained it clear enough.

Please see attachments

BTW, at my home computer, ALL accounts are showing (in Unified view) under the unified folders. Please let me know what I did wrong or if I have to explain it better.

Thanks

Is Mozilla working on the below email I have received from Microsoft? "The safety and security of your information is top priority for Microsoft. To help keep your account secure, Microsoft will no longer support the use of third-party email and calendar apps which ask you to sign in with only your Microsoft Account username and password. To keep you safe you will need to use a mail or calendar app which supports Microsoft’s modern authentication methods. If you do not act, your third-party email apps will no longer be able to access your Outlook.com, Hotmail or Live.com email address on September 16th.

What do you need to do?

If you are receiving this email, you are currently using an email or calendar app that uses a less secure authentication method to connect to your Outlook.com email account. You will need to upgrade your third-party mail and calendar app to a version which supports modern authentication methods.

Microsoft provides free versions of Outlook for your PC, Mac, iOS, and Android devices which can be easily downloaded and connect to your email account. Using an updated version of an Outlook application will ensure you are connecting in the most secure way.

How can you set up your Gmail, Apple Mail, or other third-party mail application?

Various non-Microsoft applications will have their own steps for connecting to your Outlook.com email account using modern authentication methods. See our help article - Modern Authentication Methods now needed to continue syncing Outlook Email in non-Microsoft email apps. However, you may need to contact the creators of those applications to provide you with instructions. In many cases, simply removing and re-adding your account with the latest version of that application will configure it to use modern authentication methods.

I was using thunderbird. I accidentally hit the sort by star right above the email list. The application crashed closed. When I reopen it, it immediately crash closes. I can't even get an pointer arrow for long enough to exit myself.

On window 10. Thunderbird was up to date.

Tried - restarting computer. Signing out of TB in the crash report box. Can't get into safe mode.

I hope someone can help here. I have used Tbird and FF almost exclusively from release. Thundebird is my only email program and the whole thing is playing up badly at the moment. I can send no emails. Some emails that show in the inbox show a blank screen and can not be deleted. All messages I send come back with an end of message error and SMTP blocked (see attached). This happened a few weeks ago and my email sourse gave me some new settings using port 587 and it worked ok until a few days ago then exactly the same again. They have checked and everyting works ok for them. I then checked with BitDefender to see if they could assist and everything was as expected so I did a complete computr scan with it and it came back with 3 trojan errors all of which were in Thunderbird. So I decided to do a complete delete and reinstall. No matter what I do or what I deleteincluding shutdown after every delete, when I reinstall it comes back with the total and Faulty Thunderbird So I can't start with a clean sheet. Not that I would like to as I have hundreds of contacts an email saves going back many years. Suggestions anyone

How do I correct my serious error (when tired) in allowing a Thunderbird 'Upgrade' 115.2.2 (32 Bit) Supernova to install on my Laptop (Windows 10 Home, 64 Bit). I failed to read the Release Notes by trusting Mozilla wouldn't issue such a drastic change without Warnings as it was not just an 'Upgrade'! It has screwed up my Set up, Folders etc., completely changed layout, can't find 'Write Message' tab etc. etc . etc.

The previous Thunderbird Version had many problems further introduced by 'Upgrades' but was at least still had continuity with earlier Versions with a functional MMI (man machine interface) instead of all the changes introduced with the 115.2.2, which in my opinion should be withdrawn completely. N.B My experience in Systems Control, as an Air Traffic Control Engineer, we would throw this out as not fit for purpose.

Help Please and explain how can I revert back to an Earlier Version?

In the new version of the Developer Edition the options "close tabs to the right" and "close other tabs" are in a sub-menu named "Close Multiple Tabs" inside the context menu. Is there's a way to change this so that they will appear directly in the main context menu? I use "close tabs to the right" often and I find this very annoying.

Recaptcha isn't working in Firefox. It works in Chrome, Opera, and Edge with no issues, it will either just go to a check mark or open the window with the pictures to choose, on both regular pages and on the Google Recaptcha Demo site Google Recaptcha Demo site. But when I load a page that requires Recaptcha in Firefox, it just spins forever. It was working fine a few hours ago, and I didn't change any settings or anything in Firefox. I was filling out a job application and it worked fine, then I went to another job application and Recaptcha won't work at all, even on the Recaptcha Demo site.

I'm on version 125.0.3 (64-bit), on Windows 10. Not using a VPN or anything like that, just a standard Ethernet connection, with whatever Charter gives me.

Steps I've tried, none of which have helped:

1. Cleared Cookies. 2. Restart Browser. 3. Restart Computer. 4. Restart Modem and Router. 5. Opening Firefox in troubleshooting mode. 6. Ensured Firefox was up to date. 7. Reinstalling Firefox. 8. Turned Connection Settings to no proxy. 9. Turned off Enhanced Tracking Protection. (It's set on standard otherwise, and I didn't change it) 10. Release/Renew IP via Command Prompt.

I'm genuinely at a loss of what to do, after a couple of hours of searching around for solutions. I don't get how it just stopped working in the span of like ten minutes when I didn't change any settings or anything. Firefox is my main browser and it would be a tremendous pain to have to use another browser for any pages that require Recaptcha.

Any assistance or advice to solve this problem would be greatly appreciated!

I am currently running Firefox on High Sierra 10.13.6 and have been advised that that OS will soon no longer be supported. I did have an option to do an update to ESR 115.1 in my Firefox app, however I was not home for a few days and when I returned planning to do the update it was no longer available. Now it just says my Firefox is up to date with 115.0.2... how can I get the update to the ESR 115.1? Thanks!

On a couple of websites, but in particular Rogers.com, the captcha just never ends. It asks to click on all the bicycles, I click on them one at a time until no more appear, hit verify, it brings up something else. It will do this dozens of times and just never ever end.

Switch over to Edge, does the same. Switched to chrome and it works fine. Has google done something to captcha to deny it working on other browsers?

I have checked to see firefox is up to date and it is. I have disabled all extensions/addons. I have run malware/virus scans. On the Rogers community forums there are all kinds of people having problems but there are no solutions on how to fix. Oddly (or not) the problems are similar...captcha won't work on Edge, Firefox but will work on Chrome.

I just upgraded to 128.2.2esr and cannot receive or send messages after the update. I have restarted the computer and tried again - still nothing. I'm unable to use a tool that is critical for my daily needs.

Trying to send just says "Connected" or "Sending" but never completes. Worked fine before the update which was just in the past hour or so.

Same issues with downloading new email or sending email for all accounts. :(

Anyone else having problems? Ideas?

Thank you!

I had my userCrome.css set to widen line spacing in the message list, among other things. Updating to Þb 115 broke this, and since I can't inspect the css, I don't know how to fix this again.

My current css includes:

/* Message List */

1. threadTree

treechildren::-moz-tree-cell-text {

   font-size: 16pt !important;
   color: black !important

}

/* treechildren::-moz-tree-row {

   margin-top: 0pt !important;
   margin-bottom: 6pt !important;

} */

treecol:not([hideheader="true"]), treecolpicker:not([hideheader="true"]) { -moz-appearance: none !important; padding-top: 2px; padding-bottom: 2px; }

treecol:not([hideheader="true"]):hover, treecolpicker:not([hideheader="true"]):hover { }

I tried relaxed density, but it expands *everything*, not just the message list.

Also, in Firefox, how can I use this site and avoid all the animated headers?

not sure if this is where i should be but i tried the Thunderbird help and got no answer. After the most recent Thunderbird up date and a Thunderbird install over existing one when i go to my drafts folder and click on any draft or save message in there i get a yellow bar at the bottom of the page that i have never seen before . Now i do not want recreate a new profile and lose all my contacts book marks add on etc. how do i remove that yellow bar in Thunderbird mail

I installed Thunderbird and typed in my Office 365 email information to connect my account. Thunderbird found the correct IMAP settings, which I verified on Microsoft's website. It proceeds to open a browser so I can authenticate my account. After that succeeds it starts downloading all of my messages & folders. I thought everything went fine until I attempted to send a message. I get the following error:

Login to server smtp.office365.com with username me@mydomain.com has failed.

It gives me the option to enter a new password, which doesn't make sense since it's oAuth2 but I created an app password to see if that would work, and it didn't. The only other options are cancel & retry which don't help either.

I thought maybe something went wrong with the authentication process so I uninstalled thunderbird and started again with the same results. I've tried many other server settings, but nothing works, so I'm here.

Current Settings:

Server Name: smtp.office365.com User Name: me@mydomain.com Authentication Method: oAuth2 Security: STARTTLS Port: 587

I've tried: Using Port 465 / SSL/TLS Using Port 465 / STARTLS Using Port 587 / SSL/TLS Changing Auth method to Normal Password and then using app-specific password. Uninstall / Resintsall

One final thing to note: I followed the same process with my fastmail.com account, which worked flawlessly. I can send & receive fine.

I am getting the Mozilla Thunderbird Email wants to access your Google Account all the time while using TBM, I have removed the gmail account and the pop up does not show, so I know it is for the email account just removed. I re-add the email address and enter the email address and password and let it find the config itself. Click Done, and get the Mozilla Thunderbird Email wants to access your Google Account again, then click Allow and get the Authentication failure while connecting to server imap.gmail.com. message in the bottom left of my desktop. How can i get gmail to work again please.
