A few questions after first use

[ghost]

Hi,
So I made the jump and started using the user.js with a few overrides. I still have a few settings to fix, but, even after looking around, I cannot seem to find the triggers responsible.
1/ Using the user.js has added a bar at the very top of the window ("Inbox - Unified folders), as shown in the picture below. From memory, that bar was not there before and the various tabs were right next to the traffic lights buttons, not under. Is this right? Can this be changed?

2/ I have a picture included in the signature of my emails for some accounts. This picture is no longer loaded. In all fairness, that's not very surprising, but I would like to re-allow that. I have tried resetting the parameters 9211 through 9217 (also in an effort to move back to HTML messages, for instance when responding to an message with HTML), but to no avail. I also tried 9233, but that didn't work either. Any idea which switch is responsible for this? Also interested in the plain text/HTML one (the idea being that is I respond to an HTML message, the response should be HTML, so as not to break the layout).
Thanks in advance!

Hey again Dem !

If I correctly get your point, you used to have tabs next to the traffic lights buttons (on TB v102 too ?), and now they are in a dedicated row below.
Maybe this has something to do with RFP (section 4500) as it impacts window layout... You could easily try by disabling it (privacy.resistFingerprinting), even if it is highly discouraged.

If you want to include HTML elements (e.g. an image) in your body, you will have to look at 9212 (especially the [NOTE] about shift-clicking on the compose button if you want to do this temporary 😉).
About answering to an HTML message, this is about the "auto-downgrade" feature (9213).

That being said, please note that "resetting" a preference in your user.js may not be sufficient if you previously set it. When TB is running, preferences are read, merged and kept in sync in prefs.js (which you shouldn't directly modify).
So, if you used user.js v91.1, then for instance "reset" 9212 and 9213, they would still be set to their previous values.

To workaround this, you could even :

1. reset those preferences in your user.js and open about:config to switch them back to default for runtime too
2. use a new profile and re-apply an user.js with those preferences commented out at first start

Arkenfox upstream calls that "cleaning preferences".

I hope this will help you 🙏
Bye 👋

Indeed, that worked. I hadn't applied the changes correctly.

Then I'd rather leave this be. I can bear with an extra bar.

Thanks a lot!

Actually, was 9213 (mailnews.sendformat.auto_downgrade) deprecated? When I reset the pref in the editor, it seems to delete it.

Yeah, this looks like deprecation/removal that will land in next ESR.
From source code, mailnews.sendformat.auto_downgrade and mail.default_html_action have been replaced (and automatically migrated) to mail.default_send_format.
I've added this to the project kanban for upcoming ESR work.

Hi @demided, I know this issue has already been closed but I had the same problem and was able to fix it by changing 9110 (mail.tabs.autoHide) to false.

The reason this occurs is when 9110 is set to true, the tabs are hidden when there is only one tab but there still needs to be some sort of bar so Thunderbird adds one. If you have multiple tabs, the tabs appear but the bar is still show hence two rows, as in your picture.
