Many times, I have a conversation with many messages. I may want to sort the array of conversation fields on any field. Currently, if I click on any field name, the conversation collapses.

Hi 🙂 This is a follow-up to https://support.mozilla.org/en-US/questions/1511440.

The problem is this: support.mozilla.org is a site intended for asking support questions, and it is very inconvenient not to be able to use extensions that assist with typing (notably Unicodify and Clippings).

i have 2 suggestions to do:

1) Let the user choose whether to keep extensions enabled (in which case support.mozilla.org is not privileged, the user cannot send "Troubleshooting Information", and there is no security vulnerability), or to send "Troubleshooting Information" (in which case extensions are disabled).

2) Review the design of support.mozilla.org in a way that a subdomain like ffinfos.support.mozilla.org is privileged instead of support.mozilla.org, Firefox sends "Troubleshooting Information" to ffinfos.support.mozilla.org, and extensions are enabled on support.mozilla.org but can never interact with data that Firefox would send to ffinfos.support.mozilla.org.

What do you think about this?

I created a user profile for IMAP and all was OK....Until I deleted the profile for POP and I lost all e-mail folders that I didn't move to IMAP. My PC is running Linux Mint. How do I get my lost e-mails?

hi :-)

My Thunderbird uses between 19 and 34 GB of RAM. It's cyclical (with a period of about 10 minutes).

What do you suggest?

Do I need to perform a performance diagnostic? https://support.mozilla.org/en-US/kb/profiling-thunderbird-performance

Do I need to follow all the steps listed on https://wiki.mozilla.org/Thunderbird:Testing:Memory_Usage_Problems#Diagnosis_Steps, or can I skip some of them?

I got notifications that I needed to update my email. I tried to follow the directions but after it was uninstalled, nothing else happened and now it's gone and I have nothing. I do not know what to do and am panicked because it's the only way I have to contact many people and it's really important to me.

Thunderbird 140.7.1 i have a subfolder called "purchases" which I add to on a regular basis. Suddenly no messages appear after May 2014 I have logged in directly to the mail server, and all the missing messages are definitely on the server. I have checked the local filters, none are set. I have tried properties/repair. I have tried removing ~/.thunderbird/xxx/ImapMail/mail.myserver.com.au/INBOX.sbd/purchases.msf

Could it be a problem with dovecot indexing on the server? all the other subfolders seem to work fine. It's just this one.

When filling in the PDF documents, at each section/line I move too, the font reverts back to the super large size, without being prompted too. Is there a way to set the font, so it remains the same, unless prompted? When attempting to adjust the font, it goes from super large to super small, any suggestions to set the font in between these two sizes?

• • I opened up the document from my email and began working from there. Should I use a PDF program and not from the email?**

As of a few updates ago, Firefox keeps adding items to the drop down menu in the address box. It used to have all the sites I went to to check out headlines, but it started adding things I hardly ever use. For instance I went ONE TIME to the "no calls" registry to register my phone number, and for a month that was in that drop down menu. Another, I have a number of tabs that are always open, like the weather and local radar, etc. A number of them are now in my drop down menu. So, somehow Firefox decides to drop items that I go to EVERY DAY, and put in other things it likes, like the no-call phone registry link. I would like a setting that doesn't allow it to decide this. Or the ability to delete items it adds and say that I don't want these things in that menu. It's fine that it keeps all the items I go to every day, but stop dropping them to add the links to tabs that are ALREADY open in my browser.

New install of Zorin OS 18 and new install of Firefox 152 resulted in not displaying bookmark tool bar with the imported bookmarks. Tried adding a new bookmark which displayed after the import bookmarks icon but none of the old ones. Tried to import from HTML that reported done, I closed and reopened Firefox and the same toolbar display. Is this something with Zorin or Firefox?

A large list of participants will extend the content of the "Edit Event" window beyond the threshold of the window, making all checkboxes (Notify attendees, etc.) and part of the list inaccessible.

This will also affect the Description and Attachments tabs.

With a lot of moving and resizing, the window can be resized to show everything, but then it extends far beyond the size of the screen. This is impractical.

The list of participants should never exceed the confines of the window and should be scrollable.

I love vertical the tab view. Unfortunately, on one of my systems, vertical tabs to not render correctly. Groups are shown, but there are no favicons or titles shown (see attached image). The tabs are also not clickable. Any insight into how I could debug that would be amazing!

I use Thunderbird with Threaded View enabled and would like to keep using it.

What I am looking for is a way to have Thunderbird automatically keep older threads collapsed, while allowing threads that contain new or unread messages to remain expanded or become expanded automatically.

For example, a thread receives a new message - it is fine for that thread to be expanded. All other existing threads without new activity should remain collapsed. When Thunderbird is restarted, I would like older threads to stay collapsed rather than having many previously viewed threads expanded.

Is there a setting, hidden preference, add-on, or workaround that provides this behavior?

I am using Thunderbird on Kubuntu Linux.

When I click to fill in a Credit Card field to pay for something, my correct card info appears momentarily, but then disappears. To execute a payment, I am forced to manually fill in all required information. I made sure the "save autofill" box was properly checked in the Settings, and it was. Names, addressed, etc. are all filled in properly; only credit card info is not.

when the Firefox install asks for a password, which password are they referring to?

Also, instructions say to use "sudo" in Terminal - how does one get to that ?

I have a firefox account and I sync it to at least two devices. Now I need to change some settings. When I select the change, a prompt appears, asking for a confirmation code as expected. But I never receive a code on my e-mail. I tied many times, over the last days. I checked spam repeatedly. I added accounts@firefox.com to my contacts. What could be the problem? What can I try?
