I would like to customize styling for recurring events in Calendar (115.11.1 on MacOS) without using extensions/add-ons. I enabled userChrome.css (`toolkit.legacyUserProfileCustomizations.stylesheets`) and the “has:” selector (`layout.css.has-selector.enabled`). In my userChrome.css, I added styles:

   li:has([alt*="Recurring"]) { background-color:grey !important; padding:1rem !important; }
   li:has(*[alt*="Recurring"]) { background-color:yellow !important; padding:1rem !important; }

Unfortunately, this seems to have no effect upon restarting Thunderbird. However, when I open Developer Toolbox (`Tools > Developer Toolbox > Developer Toolbox > Inspector` tab) suddenly everything works and the stylesheets are applied, but only until Thunderbird is shut down. Weirdly, other custom styles in userChrome.css work ok.

Is this intended behavior or a bug?

Hello,

I work in a company and we are using Thunderbird for emails. The way me and my coworkers work is that we solving emails we get. BUT. There are two people always here on emails. One of them is taking ODD emails, the second one EVEN. For example I'm the ODD one, so every email that comes in odd time for example 8:31, 8:43, 8:47 etc., are mine and the other person who is EVEN one have emails like 8:30, 8:40, 8:52 etc. So if I make 2 folders one will be called EVEN and the other one ODD is there some way to filter these emails by time?

Thanks for your help and answers

SLES 15.5 QU2 in Mozilla Firefox 115.8.0esr was not supporting window.close() even i added user_pref("dom.allow_scripts_to_close_windows", true); in user.js and prefs.js

Win11 Version 126.0.1 (64-bit)

When I open Firefox these days, the window is so big that the toolbar is barely visible. I have to put the cursor in just the right little spot to pull the window down and resize it. It is NOT full screen or maximized, it just opens a huge window that's too far up on the screen. I just want to resize the default window that it opens with.

Hello, it seems that cycling through tabs in most recently used order is not working for me. I am running version 126.0.1 on Windows and I have the "Ctrl+Tab cycles through tabs in recently used order" option enabled on my settings page. I have only noticed this issue in the past week or so, and so I am wondering if this feature is broken in the most recent release and if there is anything I can do to get the feature to work again until the bug is fixed in a future version.

Subfolders Expanding Too Quickly On Mouse Hover Over Main Folder *Still* A Problem

I saw a past thread claiming this problem has been fixed, but it definitely has not been fixed when it comes to dragging and dropping emails into a main folder.

Subfolders expanding (when hovering to drop/move an email) should be timed longer, and we need flexibility to time how many seconds it takes.

We need a way to set the timing of the expansion to only happen after 'x' seconds so we can manually adjust the timing.

Please fix this. It is really irritating and time consuming to have to constantly reclose subfolders.

thanks

Hi Firefox Developer Team,

I hope this message finds you well. I wanted to suggest a feature that I believe would enhance user experience: the option to use custom wallpapers or backgrounds in Firefox. Having the ability to personalize the browser with custom images would make it more appealing and engaging for users. Could you consider implementing this feature in a future update?

Thank you for your hard work and dedication to improving Firefox.

When I delete an email it immediately diseappears from the view, but if I have the "Unread" filter active and I mark an email as "read" it remains there until I switch the "Unread" filter off and then on again. Quite impractical to me.

Why do I have both a spam and a junk folder in Thunderbird?

Also, if I have to keep both, is it possible to add a menu command to empty the spam folder, like we have on the junk folder?

I maintain a "Favorites" folder view as those are the folders I use 95% of the time and I have a very large number of historical folders I need to keep around but don't need very often. Trouble is, when I create a new folder, the creation dialog doesn't offer the option to make the folder a favorite so that it disappears after creation. I have to switch to the "ALL folders" view and then right click on the new folder and check the "favorite" box and then go back to favorites view.

It would make life so much easier if there was a favorite checkbox on the creation dialog.

Thank you.

I have added many add-ons, some of them are visible in the screenshot. But i can't pin them to the toolbar. And therefore not able to use them. For some reason only three of them are visible when i click the plugin button in the toolbar and only one of them namely 'ublock origin' is pinned by default. I have tried many things but still not able to pin any plugin

I have my inboxes set to display new messages at the top. When I open an inbox, Thunderbird scrolls to SHOW new messages, highlighted in bold, at the top. Or it used to.

Recently this behavior has become inconsistent. When I look at Thunderbird, one of my inboxes may show that there are new messages. So I click on the inbox, but no new messages appear in my list of e-mails. I then have to manually scroll up to see them.

Something definitely changed here.

I can see the case where maybe I've selected an old e-mail message WAAAY down the list. In that case Thunderbird should probably open to that point. Usually, if a message is selected, it's near the top. If that message AND newly arrived messages can be displayed on the same page, Thunderbird should scroll to the top and show me new messages.

Is this a setting that can be set?

I tried redownloading Firefox after I saw that i was unable to download any extenstions/add-ons. Anytime i try to download something from the firefox browser, the download fails or gets cancelled. I never changed any settings, how can i fix this?bold text
