I use this dark mode theme: Star Trek in Thunderbird but override Thunderbird so that Thunderbird is in light mode and the folder, message list and message panes have a white background with black text. The override uses the Autoconfig method (for Firefox but it was working also in Thunderbird Customize Firefox using AutoConfig . This is my thunderbird.cfg file in Thunderbird's install folder containing:

// IMPORTANT: Start your code on the 2nd line lockPref("browser.theme.content-theme", 2); lockPref("browser.theme.toolbar-theme", 2);

and my autoconfig.js file in Thunderbird's defaults/pref folder containing:

pref("general.config.filename", "thunderbird.cfg"); pref("general.config.obscure_value", 0);

In Thunderbird 145 this worked - all panes had a white background. However, when I updated to Thunderbird 146, the background in the folder, message list and message panes changed to grey with black or white text. With Thunderbird 146, both files are still present and the prefs in about:config are present with the 2 value. The Thunderbird 146 changelog mentions Visual and UX fixes and security fixes.

My Windows 10 colour settings are: default Windows mode = Dark default app mode = Light. These are my preferred settings.

I have changed temporarily to Thunderbird 140.6.0esr and got the white background re-enabled. How do I get the white background and black text back again in Thunderbird 146 please?

My Bookmarks are missing. I see backups under the profile/bookmarkbackups folder but when I manage bookmarks, they are not in the restore dropdown. I have followed the steps to delete the places.sqlite but when I reopen firefox, I do not see the bookmarks have been restored. I thought it might have been related to Norton Utilities so I renewed a subscription but no luck. I also have a json file with my bookmarks but I cannot choose it from Manage Bookmarks, either

Over the past 2 or 3 weeks, I've noticed that firefox tabs are crashing more often out of nowhere.

Here's one of the links for the most recent tab crash. Other crashes pretty much were all the same. I can't read or understand this, so I was hoping someone who can is able to tell me what is wrong.

I fear that it might be hardware related, as I've had tabs also crash on Edge and on a new install of Firefox Developer Edition (which I downloaded simply to test if things crashed there as well.) I've also noticed programs like Discord & Elgato Wave Link sometimes randomly crashing as well - but I'm unsure how to pull logs for those, Firefox was the easiest.

My laptop's hardware specs are as follows:

Lenovo Legion Pro 5 - 16IRX9 Processor: Intel Core i9-14900HX (2.2GHz) Installed RAM: 32 GB GPU: GeForce RTX 4070 Laptop GPU Windows 11

If you need more information, please let me know.

Here are some previous crashes that I've reported as well:

Turns out you cant use your own stuff until it is approved, Sorry for this question I am absolutely new to firefox workshop. Case closed (Please delete it because I couldn't find how to do that)

I want to switch back from the Thunderbird Release channel to the ESR channel but I do not understand the steps. Please help me with the exact, easiest steps. I am running Win 11.

I can't find a setting that will allow marking messages as read only after I read them. By that I mean only after I click on the message to open it in its own tab. I view the new messages in a split screen.

The current settings allow me to leave them bold as if I hadn't read them even after I've clicked on the message and viewed it in the full TB pane

or

Mark them as read as soon as they're displayed in the bottom half of the split screen.

I don't find either of these options desirable.

It looks an update occurred but now my bookmarks Column has a white background with white type. I can't read anything there because its all the same color how do I change the background to black?

I'm trying to add a second email account from my domain into Thunderbird and on the password test page I get an error. Of course the server exists, my other email account also uses it. How do I fix this or is this a problem with Thunderbird?

All my Tabs Group have disappeared from the Tab Bar. I can see the Closed Tab Groups in the drop down but i can't find a way to re-open Closed Tab Groups. Any clues welcome. Running 146.0 and on the beta update channel.

I have been dealing with an issue in Firefox on Windows 11 for several weeks now hoping for a fix soon but it has not come yet. When I am browsing on eBay, it will lock up and I have to identify the thread in Task Manger and kill it (just the runaway thread, not the entire program). I can then continue of eBay for a short time before it happens again. This only happens on eBay while just browsing, not bidding/buying. Is anyone else having this issue?
