Hi everyone, I'm trying to customize the message list appearance in Thunderbird 140.9.1 ESR (64-bit) using userChrome.css.

Goal: I want to change the background color of the entire row for tagged messages (e.g., 'Important'). The color should persist even when the message is NOT selected (when I click on another email).

The Issue: Currently, any background color I apply via CSS only shows up when the message is selected. As soon as I select a different email, the background of the tagged row reverts to white, even though the text color remains correct.

What I've tested so far:

toolkit.legacyUserProfileCustomizations.stylesheets is set to true.

The userChrome.css file is being loaded (a global test like * { background-color: blue !important; } works perfectly).

I've tried multiple selectors: tr.tag-important, tr[data-properties~="tag-important"], and tr[is="thread-row"], targeting both tr and td.

It seems like in version 140 ESR, there's a hardcoded background-color on table cells (td) or a CSS variable that overrides the row background when the focus is lost. Does anyone know the specific selectors or CSS variables needed for this version to make the background color stick?"

Thanks everybody. Maurizio

I despise ai in every use and way with a passion. Now, it gets spammed everywhere on this browser, with no apparent way to disable and/or remove that filth. I don't want to see it, ever! Why is it even on by default??? I don't want "chatbots", "Ai assistants" or any of that shit at all.

We read "If you are having trouble viewing the full width of an HTML email in Thunderbird for Android, you can either pinch and zoom or change the viewing mode. "

Well that involves moving back and forth for each and every line.

Sure, blame it on the sender for assuming we have a desktop computer.

But now it's too late, they've already sent it to us.

Gmail gets around this by reformatting the HTML to fit the screen size.

Or perhaps we could be allowed to see the plain text version of a multi-part MIME message, like Roundcube allows us to.

The folders in my "LOCAL FOLDER" file usually have been in alphabetical order. As I have added new folders to store emails, the new folders have not been put in alphabetical order in the "LOCAL FOLDER" folder. They have been added to the end of the original list after the "Z" items. How do I re-alphabetize the whole "LOCAL FOLDER?"

I've tried everything. Nothing seems to work.

The new Profiles menu option will not go away. I have no use for it, will never use it and I accidentally select it since they stuck it right next to bookmarks. Pretty poor decision.

If there is not way to remove it then after 30 years I will be dropping Firefox.

Why is there not an option to say "no" to Firefox automatically loading when you restart your computer? There is only "yes" or "not now". I am not interested to my internet browser loading and opening once I have restarted my computer. I use my computer for much more than browsing on the internet. I am tired of always having to click the "not now" option to only have it show up the next day or two days later, where I then have to click, yet again, the "not now" option. I even went into Firefox settings and have not found an option to "op out" of this particular feature. Can you please add a "no" option to automatically opening upon restart.

Firefox OFTEN starts with a screen which reads, Sorry we are unable to restore previous sessions. OF COURSE it cannot restore previous sessions. I leave the box unchecked next to, "Open previous windows and tabs. I check the setting, delete all data on closing. I take great pains to delete data including cookies, website settings, etc, on closing, EVERY session. I NEVER want previous tabs, windows or sessions restored. HOW do I program FF to REMEMBER the setting, box unchecked next to "Open previous windows and tabs"

i used to use CCLeaner browser, but I have changed my default browser to Chrome. However, when I click on a link in an email in Thunderbird, it still sends me to CCleaner browser. I can "copy link address" and paste it into Chrome, but it would be more convenient for me to be able to click on the link and go to Chrome directly. Where in Thunderbird can I change this?

I was trying to get an email to come back at a future date and I right clicked on the email and clicked on "tag" and entered a date. Then T-Bird suddenly eliminated all the dark printing on unread messages. Is tat reversible? I need to go back to many previously unread message, but they are no longer clearly marked.

I would like to have a text label on or in place of the Get Messages icon in the tree header.

I found this suggested procedure: 1. Right-click on Toolbar 2. Select "Customize" 3. Select desired choice in "Button Style" 4. Select "Get Messages" 5. Click on Save

Nothing happens!

I asked this in alt.comp/software.thunderbird and received several conflicting replies, none of which resolved the issue.

I want to turn off ai features. I don't want to heat up the planet or torture rural people with data centers by using AI just to look stuff up, especially because ai is stupid, as in dumb, so it's a big waste of energy and water and space to use with search engines anyway. I want to be able to set up my firefox browser so it never uses ai for anything. Never! How can i do that? Idont want to have to disable it everything i search. I want it off off off off.

eigentlich = Alles im Betreff gesagt - nach Absenden steht die Anzeige im "gesendet-Ordner" doppelt. Empfänger berichteten mir, daß sie mein email nur ein Mal erhielten ...was auch korrekt ist - aber die Anzeige aller gesandeten emails in meinem Thunderbird-System erscheint doppelt. Wie - wo kann ich das abstellen? gern Ihre Hilfe mein Laptop hat Win.11

How can I get back classic so that I don't have to deal with 40 tabs - or any excess tabs? 140.9.1esr (aarch64)

The View Layout Classic (and others) are grayed out ,

When composing emails in Thunderbird for Android, I can't find any options to format text.

I can't select a typeface (even the most basic html tags for serif/sans-serif/monospace aren't available) or even make text bold, italic or underlined.

This makes it very hard to create emphasis where necessary, and it feels like ancient emails from before HTML formatting.

Is there something I am missing, or does this depend on the phone?

NB: I can do this with my messaging apps and the Gmail app, which I prefer not to use.

- Linux ver 140.7.1esr (64 bit) my folders are now out of alphabetic order among other things Trash us now under 'T' instead of grouped near the sent folder and my Computer folder has a mind of it's own. It's not under C even after I changed the name. It is just stuck. Wha? tnx

On one of my emailladdresses the emails I recieve can be placed with other emailsfrom the same person and do not show as seperate emails. All I want is for emails to be stored by arrival date and time. As an individual email. Not lost in some ancient thread.
