I have been using Thunderbird for years. Always updated to the latest version. My current Thunderbird addresses are setup through Hostgator hosting and I've rarely had an issue. I recently set up a Zoho email address and added it to my Thunderbird platform so I can send and receive emails there. Problem is, when I send a test from one of my long time Thunderbird emails to the new email that goes through Zoho, it never shows up in my Thunderbird inbox. Never shows up in my Zoho inbox either. I can send from the new Zoho email to one of my established emails no problem using Thunderbird. But it doesn't work the other way around. I've checked everything I can think of--IMAP server settings, SMTP settings, added MX records, you name it. Not sure where the hang up is. Hopefully someone can help, thanks.

Dear Firefox community,

in the bookmarks page on iOS devices, Why can't we swipe back to the previous state and we have to press the previous arrow, Is it an issue or just something else?

Would want to make this post along time ago but I thought users and developers would notice it.

really appreciate it

best regards,

I'm attempting to install a plugin to my android device to test it with web-ext, but I'm getting the error `No Firefox packages were found on the selected Android device`. Running verbose, I found it running `adb shell pm list packages`, so I ran it myself, and got the next error `Shell does not have permission to access user 10`. I have to manually specify in the command to use user 0, but I am unable to do that with web-ext as far as I'm aware

phone: SM-A13 Android version: 13 OS: Linux Ubuntu web-ext version: 7.11.0

I created a compressed (zip?) file from my prior computer. I have not been able to figure out how to get the data from that file onto my new computer. My primary need is for my tasks and events calendar. I have been able to access email accounts without referencing the compressed/zip file. When I insert the flash drive, a message pops up asking me to "insert the last disk of the multi volume set" I don't understand this request. Thanks in advance for any help you can give me

Tbird is close to perfect for me, so I regularly support it. One thing I do have occasional problems with concerns searching and using tags I hope I am wrong, but when I search for one or several emails I usually find them, but still have no idea of where they are located. The same applies to the very handy tags which I also gratefully use. I filter mails to appr 30 folders and archive them yearly, so actually finding an email can take some time. The path to the folder is not necessary - just the name of the folder would be enough to pinpoint it

Running Firefox 125.0.1 on MacOS 14.2.1, all audio input is very quiet for all applications, not just Firefox.

Experiments I ran:

• people can barely hear me in Google Meets
• microphone works great in Quicktime (making a recording) when Firefox is running but not receiving audio input
• microphone is very quiet in Quicktime when running a Google Meet in Firefox
• microphone is very quiet in Quicktime when running a discord voice channel in Firefox
• microphone works great in Quicktime when running Google Meet in Chrome

This started maybe ~3 months ago for me. I'd love to see a fix, since Firefox is my favorite browser in most other ways - otherwise I'll have to give up and switch to Chrome at long last :'(

Hi there,

I'm curious if it's possible to configure Firefox on your own to make it a portable browser. Specifically, I want to disable data encryption and machine ID checks. I know that some chromium-based browsers allow you to do this through specific switches that turn these features off, resulting in a fully portable browser. While I'm aware of third-party applications that offer ready-made solutions, I prefer not to use them for security reasons. I'd like to prepare my own version of Firefox.

I understand some may have security concerns, but I know what I'm doing. The files will be stored on an AES256 encrypted drive. Could anyone share insights or guides on how to achieve this with Firefox? Thanks a lot

PS.For those who might suggest using synchronization, I assume that, similar to Chromium, Firefox can't sync all plugin settings, and for me, plugins are essential—without them, it's not really a browser.

Hello everyone.

I'm noticing an abnormal battery usage in my Samsung Galaxy S24 Ultra. Ive used other Chromium based browsers without issues. Sadly I'll have to stop using it.

I logged into my account on my mobile browser, and was able to see all my passwords and saved data that I had on my computer. I ended up signing by accident and when I logged back in all my passwords and bookmarks where gone. How can I restore them??

Until recently when a spam email was received, I could go to my Message Filters and one set up as DELETE. After entering the spam email address I could then select RUN NOW and the spam email would be deleted. When I click RUN NOW at present nothing happens. How can I get this filter to work again.

I made my account and signed in, but now Im stuck on the firefox account and help page, if I exit so I can browse, it logs me out and asks me to sign in again. why can't I browse?

Windows 11; Thunderbird 115.10.1

I prefer to see only new messages in my Inbox. To that end, I've chosen the icon that says "Show only unread messages;" but it will not stay chosen. Every time I leave TB and come back I have to chose the icon again or see all the messages I've seen and reacted to before.

Is there a way to make the choice to see only unread messages and have it stay in use?

Many questions and answers I see regarding the sync function. I would like to know the depth of what Firefox does. I have multiple PC's and an Android. What is the depth of sync for extensions? Is it possible to have mirror images of the entire Firefox setup duplicated? It would be spectacular to move from one PC to the other and find that Firefox has the exact same setup.

Thunderbird Version 115.10.1 on Windows 10

I wrote my own POP3 server and it largely seems to work apart from when Thunderbird tries to RETR the email messages at which point I get the error "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.".

If I drag a saved version of that same email that fails to be retrieved into Thunderbird , it can write it to the Inbox without issue. That means Thunderbird has permission to write to the Inbox file and so it is not a permission issue and there is enough space. I feel like it is more likely to be something I am doing wrong in my protocol implementation. For example, could I get this error if I misrepresented the octet count? Also I notice that even though my CAPA reply does not include UIDL, Thunderbird still seems to send that request and should get the response "-ERR Unknown command".

Output from my server showing what Thunderbird sent to it: CAPA USER person@mydomain.com PASS XXXXX STAT LIST UIDL RETR 1 QUIT

Any help is much appreciated, even if it is guidance on how I can debug it more thoroughly.

Thanks.

Hi, i searched i have the same problem as last comment https://support.mozilla.org/mk/questions/1415834

This solution does not work. Firefox on Android will display a "Did you use the system camera? You must pair from within the Firefox app." when selecting the QR scanner from the dialogue box in Firefox. The option is still missing in the menu as well.
