Running TB 128.12.0esr on Linux Mint. I can get striping in my Classic View thread pane with:

1. threadPane tr:nth-of-type(odd) {

 background-color: rgb(215,215,215) !important; 

}

But how can I achieve the same effect in the folder pane? I have tried replacing threadPane with folderPane or folderTree but no luck.

In Developer Toolbox the selector for the folder list appears to be is(ul, ol)[role="tree"] but I don't know how to create a striping rule from that.

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...

Recently, after upgrading to 140, I noticed that text replacement on MacOS (Sequoia, here) seems to be functioning differently within Thunderbird; differently than in other apps I use.

What's happening is when I type a known shortcut, say "pr", the modal for the replacement pops up; if I continue typing my preferred word, the text replacement is simply inserted. I now otherwise have to press ESC to stop this. Before, I could ignore the pop-up modal and just keep typing -- that is what we expect in other apps, and this seems to be the case in Firefox (which I'm using now, and it works fine). This suggests there may be some change or difference in TB that is causing this unwanted behavior.

I do not see that there are any settings to change this -- but before I dig too deeply, I want to understand why this change was made and whether I have a choice or setting I can fix this -- or if it's a bug.

Thanks!

I get notifications from Firefox browser saying that I have messages, but if I click on the notification it just opens the browser and doesn't take me to the message that I clicked on. I can't seem to figure out where said messages are hiding. It's a little frustrating. Can you please tell me where these messages are at? It will be greatly appreciated. I took a screenshot of the Firefox version I'm running. I hope that helps.

After recent update, I can not browse any addons. The site https://addons.mozilla.org does not open, shows the connection timed out. I uninstalled and reinstalled firefox deleteting all firefox related files. The problem still persists. Other than this all the using browsing I do are all working fine. Just this extensions I cannot browse. When I click the extension icon by default it shows some extensions, I can Install them. The problem is I can not browse them. Even the recomendation tab is also empty.

PS: I am using firefox on manjaro linux.

I want to set firefox to use noai.duckduckgo as my default search engine so I can continue to type queries in the address bar. How can i change the settings to include noai.ddg as a default option?

Hello! I am an avid user of firefox (especially with adblockers) on a windows 11 PC. Unfortunately, I have recently been experiencing an issue where when I attempt to open firefox, a window will open for a split second before instantly closing again. My PC is up to date, I have tried refreshing firefox and doing a clean install, but cannot seem to overcome the issue, or even open it in safe mode. Does anyone have any advice? Many thanks in advance!

There are four (!) instances of Firefox now in Default Apps (Windows 11). From what I can glean from searching online, the fixes either involve messing with the Registry or uninstalling/reinstalling Firefox, but even these measures do NOT prevent the multiple instances from recurring with further updates. The Control Panel only shows one instance of Firefox.

What is the best approach to this problem? A "fix-it" tool would be most welcome.

I can't open the Inbox menu. Any other menu works fine; it's just the inbox menu that doesn't work. If I click on it twice, it crashes and stops working. However, email notifications still pop up properly, and the number increases too.

Chrome user returning to Firefox here; I'm experiencing an issue where most pages would take at least 4 to 6 seconds to load, especially for heavy media sites like YouTube which could take 6 seconds for it to be barely usable, and 10 or 13 seconds for it to finish loading. My internet speed is 1gb at most and 800 Mbps at the least.

It loads sites like Reddit pretty fast, like 3-5 seconds interestingly. It's largely YouTube and other sites where the pages load infuriatingly slowly, and Chrome Mask did not helped with this.

Here are the things I did: Refreshed Firefox, started in Troubleshoot mode, installed Chrome Mask for YouTube (Did not work), disabled DNS, closed all foreground apps except Firefox, used a different profile and enabled/disabled hardware acceleration.

Specs: CPU: i5-3570k GPU: GTX 1070 Ti RAM: 16gb DDR3 OS: Windows 10 Hard Drive type: SSD

Final notes, it says I use Microsoft Defender Antivirus but I am actually using Malwarebytes. I also use uBlock Origin which is the entire reason why I permanently switched from Chrome to Firefox.

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?

I've recently updated to windows 11 and downloaded the latest version of Thunderbird. For the past few days, I'm told that emails are downloading but nothing shows up in my inbox. I can still view my latest emails via webmail but not with thunderbird. I've contacted my provider and they believe the problem lies with thunderbird and not optus. I've also unistalled and then reinstalled thunderbird and the same problem remains. Can you please help? thanks, Rosetta

A few days ago, my Firefox installation stopped auto-completing my URLs. I didn't think much of it. But I tried looking up my history and bookmarks today, and they're both gone. History won't update, and I can't add new bookmarks. In-page autocomplete still works.

My Firefox version is 140.0.2 for MacOS on an M1 Mac Mini. I'd recently update my computer's operating system before I noticed the issue, and I had to do a hard power-down a day or two afterward. I do not know if the issue began before or after the hard shutdown.

After years of hoping for a dedicated new tab button in Firefox for iOS, my wishes were answered this morning when I installed the Firefox 140.2 on iOS. As explained in the release notes, there is "a sleeker, more intuitive Toolbar and Tab Tray — with smoother animations, simplified controls, and a modern look that feels right at home on iOS." What's more, it replaced the (IMO) useless "home" button with a BEAUTIFUL one-tap new tab button! I was overjoyed!

However, a few hours later, my Firefox UI has reverted back to the old way. It still claims to be on version 140.2, so I don't understand how that happened. As far as I can tell, there are no options within settings to get the new UI.

What happened, and how can I take advantage of the new UI?

Multiple times a day, I'll open Firefox Mobile and find that the settings have reset themselves: The tabs are set up in grid view, and the homepage has had sponsored shortcuts added, with Google, Wikipedia, and something about trending stories pinned, as well as stories/sponsored stories toggled back to on.

This happens multiple times a day. Sometimes I will open it and find that not only have my settings reverted in this manner, but *multiple* Google/Wikipedia/trending shortcuts have been pinned.

How can I stop this from happening?

How can I use ECOSIA as my search engine? ECOSIA is a search engine that "plants trees." I'd like to support the environmental nature of it.

Copied Thunderbird Profile on old computer to external HDD. Name assigned was zs6…. Installed TBird on new Win10 PC, omitting sign-in procedure. On this PC, clicked Menu, Help, Troubleshooting Info. Opened Profile folder on this PC, left-clicked Roaming, closed TBird. Copied zs6… from ext HDD, pasted onto TBird folder C:\users\owner\appdata\roaming on new PC. Clicked Yes to replace any existing files. Opened \roaming\thunderbird\profiles zs6…. not in there. TBird launches again in Setup. What am I doing wrong?
