Ciao :)

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

I can't send any emails with my personal outlook account. It always says "Login to server smtp.office365.com with username xxx@outlook.com failed." Receiving mails works fine. Both my IMAP and SMTP authentication are set to OAuth2.

Here's my account info found in troubleshooting information.

   account14:
     INCOMING: account14, , (imap) outlook.office365.com:993, 3, 10
     OUTGOING: , SMTP.office365.com:587, 2, 10, true

I've tried:

• Removing and re-adding the account
• Deleting oauth2.issuer and oauth2.scope in config editor and re-login
• Adding the account in a new profile
• Switching to basic authentication for SMTP

They don't solve the issue.

when i oppened tbird on windows 10, it showed a page to obly my for a donation. i had made a donation short ago, but eventhough, i just made another one time donation. when i open tbird again, i can not get out of the donation page. what should i do please???????

I have a profile that causes odd behavior, within the profile, and to the OS.

Regarding the profile itself:

1. I use Multiple Tab Handler, which should allow me to move tabs on the tab bar with the mouse, but it does not (see image of proper behavior)

2. Normally, i can drag this padlock button to the desktop to create a shortcut. but now, it will not move/drag (see image 2)

3. I also have a backup profile from several months ago that has none of the above symptoms. However, If I substitute it's sessionstore.jsonlz4 file with the the one from the problematic profile, all the bad behavior mentioned above re-emerges.

I know this sounds strange, but, I also get external display issues when using the broken profile. These events are random, and manifest themselves differently, so I can't duplicate them. Essentially, these snips are examples of images from the taskbar tabs, or the clock area, suddenly superimposing themselves on the top portions of the taskbar toolbar area.

This is the view of my clock area (see next image 3)

In the following image, imagine that the portion on the left, that opens the start menu, is now hidden under what looks exactly like the clock area on the right, superimposed over it (see next image 4)

Those aberrations are removed by simply moving the mouse cursor over them, but they will continue to occur in any number of variations over any area of that top toolbar.

Is there a Session Manager that will save the session, to be later restored into that previous profile, but not also pass along the corruption?

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 everyone,

I'm working on a privacy-friendly email setup and ran into a challenge with Thunderbird.

My setup: I have a catch-all email address that forwards all incoming emails sent to *@mydomain.com to my real mailbox, secret@mydomain.com. This way, I can use aliases like alias1@mydomain.com, alias2@mydomain.com, etc., without exposing my actual address.

This part works perfectly.

The problem: When replying to a message sent to alias1@mydomain.com, Thunderbird automatically uses secret@mydomain.com as the sender address. That defeats the purpose — the recipient now sees my secret address, which I wanted to keep hidden.

Thunderbird offers a workaround via identities, but it requires creating a separate identity for every single alias, which becomes unmanageable if you use a lot of them.

My attempted solution: My idea was to have my mail server insert a header like:

X-Alias: alias1@mydomain.com

Then, on sending, the server could rewrite the From: header using that value — thus preserving the alias and protecting my actual address.

However, I discovered that Thunderbird strips custom headers like X-Alias when sending. That breaks the solution.

My questions: 1. Is there any way to configure Thunderbird to preserve specific custom headers like X-Alias during sending? 2. Alternatively, is there a better or recommended approach to achieving what I’m trying to do — replying from the alias address automatically, without exposing the real one, and without creating hundreds of identities?

I’d really appreciate any ideas, insights, or suggestions. Thank you!

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.

I am using the latest Fiefox and i have disabled all adons i have tried everything I have changed my Facebook password every time i g try to share something on Firefox get a black box on the bottom right that says something wrong . I have tried to copy the entire hing but can not i got some of it I have even reinstalled firebox ans still can not share anything I have tried contacting Facebook but that does not happen no response i appears to work in Chrome on a noter Facebook account so it is Firefox. i will send you what i could get on the screen shot the part that is missing s the part that says something s wrong

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.

https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-06-28-08-45-55-a5277f.png

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?

Hello,

I have saved thousands of emails over the time in several local folders. Near 8Gb of emails with their attached documents. The local folder is in a Synology NAS in my local network.

I was trying to retrieve some of the emails saved in that local folders and found that I couldn't read any of the saved emails. I could see the list of the emails in all the folders but when clicked in one of the emails of the list, nothing was showed.

By saving all the files to the computer, I can read again all the emails. Never happened that it was a problem to read from the NAS. I could see a status bar in the bottom of the window showing the progress in the loading and after a short while, the email and the attached files were shown and loaded.

My local network seems to work ok and also the Synology.

So, my question is, has anything changed that blocks the reading of emails from the local network? Any idea on how to have the emails stored in the NAS?

Thanks

Why does this happen? I was even logged in, and my tab groups are gone. Why??? Do I need to use a different browser? And Firefox has had trouble with some websites where the paying portion is not correct. However, if I go to a different browser (Chrome), the paying portion works correctly. I'm getting kinda tired of these weird things going on. Please don't offer a feature that doesn't work like grouping tabs.

Today: Can't access website. I think it is the ISP or the router. Reset the router. No luck. Tried a different device on the Wifi. Works fine. Tried a different browser. works fine. Shut down Firefox. I had 2 browser instances open with several windows in each. Could not restart firefox, as it did not close correctly. I closed the broken instance(s). opened FF again, only got one set of windows, not both sets. The other instance had a bunch of grouped windows, and the groups seem to be gone. I can recreate most of those, but had some windows with ongoing work and things I wanted to look at and now they are gone.

FF crashed when I tried to get some answer from ediblearrangements.com help.

When I launch Firefox in Troubleshoot Mode and try to open the Settings page (about:preferences) right away, Firefox becomes unresponsive. This issue does not occur when Troubleshoot Mode is off.

I'm using Firefox 140.0.4 on macOS Sequoia 15.5.

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.

starting just now, firefox will not take me to ANY website. All other browsing services are working. I have tried uninstalling and reinstalling and clearing cache and cookies.

If I cant get this fixed for my job I will go back to chrome and never download or retry this again. I will also never recommend firefox to anyone like I have in the past.

I find myself in an unfortunate situation; my computer was remotely accessed without my permission, my email and data compromised, identity stolen and more. While I have been working on that, and reporting such things to the appropriate companies and authorities, I am left in one of many unfortunate situations. My Firefox account was signed in, thus leaving passwords in the manager compromised, as visible as if it were someone sitting at my computer with it unlocked. I am working to change those passwords, documenting them offline, but I am worried to sign into my Mozilla account on a desktop computer, in the event that any malicious add-ons or extensions were installed. 1. Does being signed in to the mobile Mozilla leave me at risk of Spyware if any such add-ons or extensions were installed to the desktop client? 2. With the add-on and extension auto-sync that happens with signing into a Firefox account, I am worried that even if I buy a new computer, modem and router, that signing into the Firefox account could risk compromising the new computer and network. Can these add-ons and extensions be removed or unlinked from the account in any way without signing in on a desktop/laptop?
