Whenever I open a new tab using the + sign the background color is black. I have tried everything I can think of and what I found on the web. Nothing works I hate the black background. I want white with text in black.

I'm attempting to write a Thunderbird add-on using the MailExtension API.

I've created a folder with a manifest.json and background.js, and I've got the Hello World example code entered into the files.

I'm trying to install that Hello World example code into Thunderbird as an add-on, but I can't find any documentation that explains how to do that.

The Mozilla documentation for the Hello World example project suggests downloading all 3.5 GB of the full Thunderbird source code, and building a whole new thunderbird binary with the changes built in. Obviously that's insane, and I can't imagine it's the proper procedure for building a simple add-on comprised of less than 15 lines of code.

How would I go about adding a simple custom-made add-on into the standard, already-installed version of thunderbird that's currently running on my system?

Thanks in advance!

I use my PC with english language but few times Thunderbird has changed to my native language finnish and it stays there. Language options is set to english but still all is in finnish. Why this is happening and how to keep on english?

I find no option to add addresses when I click Firefox menu bars on top right of my screen. Setting provides no options, there is no preferences header, so I can't proceed.

I have been using the theme Dark from Mozilla for years and years, but suddenly, like in the last 3 days or so, it appears that it is forcing every single freaking website to use dark mode, and I don't want it to do that.

I tried the "Colors" option in the "Fonts and Colors" section, but didn't that isn't at all what I want. Thing is, if I change to a "Light Theme", it forces the sites that I want to be in dark mode to be in light mode.

Can anyone help me?

I am highly distractable by screen movements of any kind, and prefer that nothing on my screen moves unless I ask it to--no autoplay or running ribbons of text or even slideshows with pictures slipping past each other unless I specifically click to make something move. But none of the adjustments I've found in about:config have stopped the snowflakes that drift down across the screen on

during December. I'd like to stop them in my viewing but not be the killjoy that demands they be taken down for everyone, because lots of people actually like them.

Any suggestions on what setting to tweak for this?

I have been using the -no-deelevate command line option to launch my main browser profile with a shortcut to Firefox.exe without any problem since it became necessary. However, I am unable to start my other profile to allow dragging. Is there a way to do it, please?

Hi,

I want Firefox to save files without asking. I need it for E2E test automation, recentyl something has to change in update because even in GUI I don't see an option to remember my choice. In case of E2E framework I had a setting which was working but now stopped to work:

desiredCapabilities: {

               browserName: 'firefox',
               alwaysMatch: {
                   'moz:firefoxOptions': {
                       prefs : {
                           "browser.helperApps.neverAsk.saveToDisk": "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet",
                           "browser.download.folderList": 2,
                           "browser.download.dir": downloadsFirefoxPath,
                           "browser.download.lastDir": downloadsFirefoxPath
                       },
                       args: []
                   }
               }
           },

How to do it today?

Hi

I noticed that one of my add-ons were not working anymore. I tried to reinstall it, but got an error message. "The add-on downloaded from this site could not be installed because it appears to be corrupt." I then noticed that none of my add-ons were working except for the language pack and Lightning. I assumed I had a corrupt file in my profile folder. First I deleted the extensions.json file . That did not help. I wanted to clean up. I uninstalled all extensions. Then I deleted the following files and folders: addons.json, addonStartup.json.lz4, extensions.json, extension-settings.json, extensions and extension-store. That changed the default language of the GUI. When I try to add a language to Thunderbird I get the following error message: "Thunderbird can’t update your languages right now. Check that you are connected to the internet or try again". I Still can't install any add-ons.

I use a Firefox account on two different machines- one is a Mac and the other is a Windows machine. I have some programs installed on the Windows machine that installed an extension for Firefox. Those programs are not Mac compatible but because of the same account, those extensions were copied to the Firefox installation on Mac. I was wondering if there is a way to isolate the extensions to just the windows installation? Thanks!

Have latest version of Firefox Browser on my macbook. Used to be when I "Bookmark Current Tab" I could select where that bookmark was saved but not just goes into toolbox. How can I change that so once again I can save to bookmark folder I want?

Hi. I made my own custom theme a few weeks ago, and I liked it. It has a dark toolbar, but the automatic new tab was still light. I liked it this way. I updated the browser today, and now it's essentially in dark mode and I can't find how to change it back. I really hate white text on a black background, and as I did not choose that as part of my custom theme, I would really appreciate being given the choice to change it back.

We’re a small company but aiming to find an email client with an ability to customise its’ look, based on our design expectations. We do have our corporate colors and styles, and would like them to be implemented within the email client.

We can come up with the UI design and would be great if someone will have an ability to implement it. Maybe there's a design team who can work with us etc.

- Can Thunderbird be design-customised? - Can someone advise a person/company who can implement this idea? - Can UX be customised? (we do not expect much here, but just in a case). - Can someone set up the final product for our employees?

Thank you for the prompt reply, Vlad

So I've got Proton UI forced on me today in 92.0 update and accordingly had to spend my entire evening trying to repair all of the damage. So far I've managed to fix menu spacing and the way tabs look all while not breaking previous walls of text in userChrome.css meant to fix even older UI problems. Still one thing I failed to find any solutions to is the bookmark drop-down menus color issue. Those menus used to be gray, but now they are all bright white, which to me is super annoying. Any tips on how to fully recolor those?

I set up firefox to use the search bar, and the first time I used firefox I typed into the search bar and it worked that way; however, each time thereafter when I typed into the search bar the text appeared in the address bar. I have tried resetting the selection without success. Any suggestions?

msn.com will no longer allow any of my browser extensions to block display of the home page search box and other items on that same horizontal level in Firefox. The tools to select elements to block only select the entire page. In IceDragon, I can still block individual elements. I complained to msn about that.

Hi, I am using Thunderbird 91.2.1 (64-bit) on Windows. When I click on Find more add-ons, the addons.thunderbird.net site show that most all the addons are incompatible. And those that are indicated as compatible are compatible with older versions. See attached e.g. for smart templates. Is it because of some preferences set wrongly?

Regards.

In Android when opening any links from any App, they open in the App. There is an option to disable in-app links in some apps but not in all and it is lengthy to do it one by one. In chromium browsers we can disable them with this option called custom pages (might be called little bit different) where if it is turned off, the apps will open links in browser fully no matter their settings.

Is there a way like this in Firefox? The option called Open Links in Apps does not seem to be working as I have it turned off but it still lets Apps open links in themselves.
