I used to use these add-ons

Old Icon Phoenity Buttons Phoenity Icons

to make Thunderbird more attractive, but now I'm having constant problems. The interface has become schizophrenic, and every time I open it, the icons have a different style, so I've been forced to disable the add-ons.

The question is, are there any supported add-ons left? I can't find any on the website. :(

I am using MacOS 10.13, Thunderbird 115.15.16ESR: my Hotmail worked until 15 May 2025 and then it would not download new emails. Screenshots are available if you want me to post them. I got an error message: "authentication failure while connecting to server outlook.office365.com". I updated Thunderbird to the latest for my OS: 115.18.0ESR. Still no new emails. I deleted my email account on Thunderbird and tried to reinstate it. Now I get an error message when trying to set up the account: "Unable to log in at server. Probably wrong configuration, username or password." I tested my password by logging into my Microsoft account with it on my browser. I can also login to my email using Firefox, but I want my Thunderbird email client to work again.

The configuration I am using is: I use my normal hotmail password in the password field. I also set up a new App Password with Microsoft and tried that without success. With the 115.18 update there is a new field: Your login. I just put my hotmail email address in here. incoming: outlook.office365.com, port 993, SSL/TLS, Oauth2 
outgoing: smtp.office365.com, port 587, STARTTLS, Oauth2 (I have also tried: smtp-mail.outlook.com)

I enabled 2-step authentication with Microsoft in my Microsoft account more than a year ago. Interestingly, I don't get a prompt on my iPhone Microsoft Authentication App when I select Done when trying to set up the hotmail account on Thunderbird.

Please help. I am desperate, and I have wasted a lot of time on this without success. Cheers

Failure to download email from Optus. I have spent a number oif hours to no avail talking and typing with the Optus staff regarding this problem. 1. I can send email from TB but cannot receive. 2. I can see the incoming emails in their Webmail site. 3. Optus confirm my settings are correct for both the mail server and SMTP server. When I go to Settings> Security > Passwords > remove server so I can re-submit my password, the only one showing is the SMTP server. Should the incoming mail server also be shown?

I am frustrated and ready to dump TB but have bee with it many years and don't want to start again with another programme as I am 83 and am partially blind. Please can anyone assist?

Hi, at the top of the picture are 6 emails. Towards the bottom, highlighted in blue, is another email, RPAiken4@gmail. How can I get that one to be in the group of 6? TYIA

Windows 11 64bit. I have Outlook and Gmail accounts. About 6 months ago the Outlook accounts stopped sending messages. Ok, I can live with that as I only use them sparingly. I tried lots of tweaks from this forum but none worked. I am not technically minded so I may have interpereted the wrongly. After the last update 9/10 July 25, the Outlook accounts fail to open. Says something about cookies not enabled on browser. I added the logins to the exceptions but no change. The cookies show on the list as on the PC. So I can't use Outlook anymore. Gmail. Now I can't send any messages from Gmail accounts. Just waits ages and says try again. The email I was replying to disappeared from my inbox when I logged through Google Gmail account. It shows on Thunderbird. I also tried to set up a new Gmail account on Thunderbird, would let me. So now, Thunderbird is useless to me. Shame, I liked it and even donated. How could something go from good to useless in one update?

Some web sites such as Amazon have an options bars to select items like 'review order'. When the web page first comes up, they show white in the dark bar. But Firefox is immediately changing the white to purple so that it is almost impossible to read. I haven't been able to find anything in settings to correct this. I do not have this issue when I use Chrome.

What the title says. Firefox just isn't playing any sound whatsoever.

Troubleshooting:

• Volume mixer indicates that Firefox is using my speakers, along with all other apps. When playing a YouTube video, the green bar is not bouncing. However, all other programs that play sound do so successfully and their green bars are bouncing (see attachment).

• Other web browsers play sound successfully.

• Restarting Firefox and my computer did not help.

• Switching the default sound device and changing back did not help.

• Changing to headphones made no change.

• Tabs are not muted.

• Autoplay settings in about:preferences showed that audio and video were disabled, however changing this setting to allow video and audio, then restarting both Firefox and the computer did not fix the problem. I have no idea how that setting was even changed to begin with. O_o

• Started Firefox in troubleshooting mode; still no sound.

• Started Firefox in a different profile; still no sound.

• Started Firefox in private mode; still no sound.

• Tried ending the audiodg.exe process in task manager and restarted; still no sound.

• Double checked media.autoplay.blocking_policy, was set to 0.

• Double checked media.block-autoplay-until-in-foreground -- changed from true to false, restarted Firefox; still no sound.

• Disabled hardware acceleration; still no sound.

• Refreshed Firefox; still no sound.

• Complete uninstall, including the usage of BCUninstaller to uninstall "leftovers". Reinstalled. Still no sound.

I have Apollo installed on my computer and I've reached out to them before for similar issues, but the dev was insistent that Apollo does not cause sound issues. I'm somewhat sceptical, but they're not being helpful at all so I thought I'd ask here, and disclose usage of Apollo so that all bases are covered.

Thank you for your time.

I try to access my messages from an outlook.com account with Thunderbird mac. I get the error message "the STAT command did not succeed". This happened suddenly today without changing any parameter. POP is enabled on this account. Moreover on another mac with Thunderbird everything is correct with the same account. Cookies are enabled I tried changing OAuth2 to normal and changing back. No sucess. What could I try next? Thanks.

I have a Suddenlink.net email account that I can't seem to install. Suddenlink has been purchased by Optimum. I have all the requirements that Optimum has given, but it still won't load. my email address is dluenser@suddenlink.net. My password is correct because I can go to their site and get my emails. These are the requirements that they gave me. Again, it is a suddenlink account. Can you help? I've tried numerous times to work with Optimum techs, but they are not knowledgeable to what I should do.

Server Settings by Domain Use the following server settings to set up most third-party email clients or applications to send or receive Optimum email. IMAP (Inbound) Optimum incoming mail server: mail.optimum.net Suddenlink incoming mail server: imap.suddenlink.net Incoming mail port (SSL): 993 (Secure Connection. Recommended if your mail client supports) POP (Inbound) Optimum incoming mail server: mail.optimum.net Suddenlink incoming mail server: pop.suddenlink.net Incoming mail port (SSL): 995 (Secure Connection. Recommended if your mail client supports)

SMTP (Outbound) Optimum outgoing mail server: mail.optimum.net Suddenlink outgoing mail server: smtp.suddenlink.net Outgoing mail port (SSL): 465 (Secure Connection. Recommended if your mail client supports) • Check My SMTP server requires authentication Username and Password (if needed) User Name: Your full email address, including the @domain.net at the end (i.e. @optimum.net, @suddenlink.net) Password: The password for your particular email address • Outgoing server verification/authentication must be enabled and on. If your email client has the option or checkbox that says My outgoing server requires authentication this will need to be checked along with use same settings as my incoming mail server.

First got a msg box from Firefox that my W10 PC had crashed overnite - and I could report it. My PC was back up & looked normal - but when I accessed Firefox the PC crashed - then I got the above error & blue screen and could do nothing on the PC! I restarted again - as long as I DO NOT START FIREFOX - my PC is fine. Help pls! For what it's worth, I happened to open a lot of tabs in Firefox yesterday. Drivers are up-to-date. Vicki

My filters seem to work for emails received but not for ones I've sent. I use the rule "From, To, CC or BCC" combined with a persons email name (i.e. preceding the @ sign) and while From works the To doesn't and remain in my sent folder. Periodically I have to use "Run Filters on Folder" or "Run Now" from within the Sent folder to move everything to their respective folders. Do I have to have a separate rule just for "To"?

Ok so I usually choose these option to remember history and from time to time delete Browsing & download history and Temporary cached files and pages.

Note: I have "Open previous window and tabs" ticked in general settings which also has a restore previous session option in the history menu. This brings back previous session with tabs etc as is when I close FF. https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-06-28-08-45-51-cf2daf.png

I thought I could automate this on exit but don't think its working right. So I change the option to "use custom settings for history" and tick all three options:

Remember browsing and download history Remember search and form history Clear history when Firefox closes For "Clear history when Firefox closes" I ticked Browsing & download history and Temporary cached files and pages. https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-06-28-08-45-43-b10213.png

The issue is the restore session option is missing and FF opens with all previous tabs gone. I am frankly not even sure what else is missing such as cookies, site data etc. Is this meant to work like so?

Hi I have a company email account with a large amount of emails accessible from several computers. I created a local folder in Thunderbird on my NAS drive and directed the locations to it on my computers. I have emails sorted by year, as well as received and sent. When I open the program, I can see the email subject, recipient, and date. However, I can't open any of the messages; both the quick preview and the separate window show a white background. What's the problem?

Hi. I'm still new to Firefox and don't really know the settings very well. I recently switched over to using it and realized that when I use most drop down boxes the background of the drop down menu is black, but the text is white and the selection box (when you hover over the item) is also white. Making whatever I'm hovering over very hard to see. I'm wondering if I have a strange setting turned on or not?

Settings wise I have Firefox set to dark mode, not the auto. But when I use the auto it still happens. Trying it in safe mode it still happens. Iv tried to research this a little myself. And read something about the proton setting and turning that from true to false. But this also did not work.

Is there any way to fix this? I just need the text to be a different color or the selection box (when you hover over it) to be a different color.

Attached are two screenshots of what I'm seeing

recent pop-up when signing in to my mail acct. "sign in with google...sign in to continue to Mozilla thunderbird email" allows me to continue if i ignore it, but keeps coming back. also pops up if i attempt to add a task to calendar. suggestions? thank you
