I have autoconfig.js set up to run my own js file, see below. The intention is to change the keyboard shortcuts (shame that it's so difficult😃). It worked until a few weeks ago. Now it only partly works. C+J is fine. The other two succeed in deleting the existing command, and the shortcut key does nothing. Any ideas please?

// C+J = open downloads var element = document.getElementById('key_openDownloads'); if (element) {

 element.setAttribute('key', 'j');
 element.setAttribute('modifiers', 'accel');

}

// C+D = Duplicate tab var element = document.getElementById('addBookmarkAsKb'); if (element) {

 element.removeAttribute('command');
 element.setAttribute('oncommand', "duplicateTabIn(gBrowser.selectedTab, 'tab')");

}

// CS+N = move tab to new window var element = document.getElementById('key_undoCloseWindow'); if (element) {

 element.removeAttribute('command');
 element.setAttribute('oncommand', 'gBrowser.replaceTabsWithWindow(gBrowser.selectedTab)');

}

Hello everyone. I use the firefox browser for years with the windows 10. I used to click on a favorite website with the right mouse button. Drag and drop on the Firefox icon in the taskbar at the bottom of the monitor. When I need this website again, I would just right click on the firefox Icon in the taskbar and would see a list of all my saved websites. I would select the website I wanted and that opened my preferred website oince again. Since I have upgraded to windows 11 this no longer works. Can anyone tell me if this is still possibke to save the preferred websites in the firefox icon in the taskbar? Any help would be greatly appreciated. Thank you

Hello, I have recently been unable to create new messages in Thunderbird. I am currently on the latest version, 139.0.2 (64-bit). There is no Create New Message Button, and Control + N does work either. I am also now getting a lot of extra information in the Header Pane. Refer to the Screen Shot JPG. Thanks, Graeme

Many of my mailboxes on the IMAP server just emptied. They were still there in my Ubuntu '.thunderbird' ImapMail directory. I have created some replacement mailboxes in 'Local Folders' and copied mbox files from the ImapMail area to the Local Folder area, removing the .msf files just created by Thunderbird. I then used the Properties->Repair Folder on each of the the new Local and filled-in-the-background mailboxes. Many worked fine and I was able to repopulate the IMAP server mailboxes using drag in Thunderbird. Some, however, were mis-parsed, producing 'From-less' and Subject-less messages containing part messages. Thunderbird seems unable to reliably parse mbox files created by itself. I note that they are not strict mbox format, having a '-' instead of an envelope address on the delimiting '^From ' line. (I am a retired Unix SysAdmin, so used to the command line)

Description: while viewing videos on youtube, twitch, odysee (and possibly other sites with videos), the video player may suddenly stop playing, and after that, no video in firefox can be played. Restarting the browser makes this issue disappear for a while, but i'd like a permanent solution.

What i've tried so far: Disabling uBlock Clearing cache and cookies Enabling/Disabling hardware acceleration Disabling proxy extension Disabling antivirus on PC.

Lately I installed a new PC, and tried to download FireFox and sync my data. But my data seems like a few years ago, not as new as another PC I have now. I'm sure I have logged in with same account on them, how's this happend?

This is offered as Mozilla support but it mihht never be answered

Please tell me my sign in email so I can check passwords and logins in Firefox for a uRL subscription that suddenly doesn't work on my 

Android.

I have "Always ask you where to save files" checked in my preferences, yet Firefox saves downloads to my Downloads folder without asking. This was working in the past, it's only recently broken.

I'm using Firefox 140.0.2 on Mac (aarch64).

What's wrong with the new release?

Today i decided try the new firefox(140) since it's going to be ESR, but i'm getting hot-fan from a couple of tabs (particularly video streams). Second it's slower and seems to have 4second delay for shutdown..

The laptop is running linux mint with intel i5 (11th), tigerlake (iris xe) gpu. It might not be newest, but it shouldn't have a problem with regular web browsing.

Is it a bug? like it's not maxing my ram or cpu during use.

Hi. I installed Firefox on my old Hp, and have now taken another laptop, an Acer Aspire One and installed Firefox on that as well, but a extended support version. I am struggling to import all my bookmarks (ex Chrome) to my Acer, and in the struggle I done something wrong since Firefox on the Acer is now locked or blocked !! I am an "old Timer" and not very computer literate. Can someone help me solve these issues so that I can move away from the HP and depend on the Acer. I found Firefox easier to use as compared to Chrome, which seemingly demanded more memory from the computer.

When I start Firefox without any internet, i.e. Airplane mode, the browser starts up pretty quickly. However when I connect to internet, either via WiFi or LAN, the startup time increases dramatically. This means that Firefox is connecting to the internet, waiting for some server to respond and then finish the launching of the browser. I have been able to figure out that Firefox connects to the following URLs when it launches.

1. cdn.statically.io
2. img-getpocket.cdn.mozilla.net
3. ublockorigin.github.io
4. aus5.mozilla.org
5. content-signature-2.cdn.mozilla.net

Please note that this is not the complete list, it is just what I have been able to figure out. There might be other URLs that Firefox connects too, which I am not aware off.

So my questions are as follows 1) How do I come to know all the URLs Firefox is connecting too, when it launches? 2) How can I check how much time does the server take to respond back to Firefox? 3) Is there a way that to stop the connection between these servers and Firefox? For example, pockets is getting shut down and I do not use pockets. So I maybe the connection to img-getpocket.cdn.mozilla.net can be terminated or stopped. OR maybe the connection to content-signature-2.cdn.mozilla.net can be asychronous and need not hold up the browser loading and so on

New computer Ubuntu 24.04 Mate, older Ubuntu 22.04 Cinnamon. Following support transfer directions (open Thunderbird on new PC, close it, paste a copy of older .thunderbird from USB stick to .thunderbird on new, over write), when I open Thunderbird no accounts are shown only the create account screen. I find no update path for older Thunderbird. New PC came with 128 esr but I found a tarball of 115 .18.0, installed it and followed transfer directions with the same results. Seems like the esr version uses a profile ending with esr and ignores my older one. What are my options for transferring 20 years of significant messages? The hard way might be to identify the account specific files in my older profile and copy them into the new esr profile...
