The Contacts Sidebar is blank when I write, reply to or forward an email. I have TB 91.3 running on Linux Ubuntu 21.1.

"Show Contacts Sidebar" shows a sidebar like in the attached image.

Please can someone help find a solution? I am not very technical so don't hesitate to explain in very simple terms. Assume I know nothing and you will be close to the truth.

My Google Contacts are linked to the Google Address Book by CardBook.

In the search settings it is possible to add a search engine not in the list. Qwant.com is an excellent, privacy oriented search engine far better than DuckDuckGo in my experience. However, it does not follow the format Firefox for Android requires which is to add "%s" at the end of the string. Please let me know the exact string to use to add Qwant.com Thank you for all of your help. Please just provide the string needed in quotes if possible to make it very clear.

After decades with Thunderbird, I suddenly find I can no longer open my emails – and I'm constantly bombarded with one of the three messages (below). How can I fix this?

1 - “Server has disconnected. The server may have gone down or there may be a problem.”

2 - “Unable to connect to your IMAP server. You may have exceeded the maximum number of connections to this server. If so, use the Advanced IMAP Server Settings dialogue to reduce the number of cached connections.”

3 - “Sending of the message failed. The Outgoing server (SMTP) does not seem to support encrypted passwords. If you just set up the account, try changing the 'Authentication method' in 'Account Settings Outgoing server (SMTP)' to 'Password, transmitted insecurely'. If it used to work but now doesn't, you may be susceptible to getting your password stolen.”

I would like Firefox to access the Mac OS "Dictionary" for immediate definitions, the way it accesses its own dictionary for spelling, or as Mac's Safari, accesses the Mac dictionary. I see nothing listed in Firefox>Services, nor does the OS's Services Preferences show Firefox as an app to connect services to. I can always get the definition with a right-click on the highlighted word, but I'd like the definition to be a readily available as the spelling.

TIA,

Most mobile sites are of a lower quality than their desktop counterparts. Less features and constant requests to download unnecessary apps are annoying and waste screen space. How do I force the Firefox app to only open desktop sites?

Because when I do the toggle bar it only works for one tab and when I open links to new tabs, it switches them back to the mobile version. Which for some sites that prevents me from being able to read or access things because the mobile version switches to a page that is just a prompt to download the app and clicking the desktop toggle doesn't bring me back to the page I wanted.

I saw there used to be an addon that would have been useful. It's dead now. Is there any useful replacement add on? Any convenient workarounds?

After the last update to Firefox on my Mac Book Pro running Mac-OS Monterey, I was offered an update to Ad Block Plus. This add-on, AdBlocker Ultimate shows as installed but it won't run at all and shows as disabled and my existing AdBlock Plus quits working. I'm using Adblock Plus on my windows based computers with all synced together with the Mac Book and the Windows computers are OK, but not the Mac Book. Is there any way to get my Mac Book working correctly? In addition the last update to Firefox on the Mac Book opens by offering me "Life in Color" every time it starts up. How long do I have to tell it I'm not interested? Thanks for your help.

We just moved and have Spectrum as our provider. My husbands email ended in Spectrum.net and mine twc.com I got his set up in Thunderbird but I cannot get mine set up. Any help would be great.

My bookmarks toolbar disappeared. I was able to restore it, but it's blank. Using an add-in, I can show my bookmarks in a side pane. That pane does show a Bookmarks Toolbar folder, which has the expected contents.

Additional issue: how do I rearrange my toolbars. The desired order, from top to bottom is title menu navigation tabs bookmarks

Windows 7 Pro, Firefox 94.0.2

Much thanks!

hi, i have a dozen extensions that i wouldn't mind keeping in case i want to use them sometime, though i know you're supposed to keep extensions to a minimum to avoid complications and slowness. Does disabling add-ons avoid the problems just like deleting them altogether would? thanks!

I simultaneously open two links of a bookmark folder by using the mouse scroller click. This is a most useful action, but once the pages are opened, they have to be re-selected to be pinned. Is it possible to open them in pinned mode?

As of Thunderbird release 91.3.2, the composition screen default background color is black and the default text color is white. I cannot find where to set my defaults as black ink and white paper- as life has been since the invention of both. I can reverse the colors for each message I compose, but cannot get it to stick as a default.

Please advise.

On Firefox 90 on Ubuntu 20.04, when a site asks for camera and microphone permissions, it’s not possible to select any device anymore. It just shows the default camera and the default microphone.

Earlier Firefox releases used to show a selection list for the camera and also another one for the microphone.

My default camera is the one built into the laptop and I would like to use an external one that has adequate picture quality.

Can you please help selecting a camera with the new Firefox?

After the last update to version 95.0 all websites such as github.com changed to dark mode. I am using the dark theme but I still don't want to use dark mode on websites. Is there any way to use the dark theme without using dark mode.

Thanks in advance!

Hello! I am using the userChrome.css file to hide the nav bar (# nav-bar) and show it when hovering the tabs.

The following code works a bit, but when I open the developer tools they overlap.

# nav-bar {
   z-index: -1;
}

# navigator-toolbox: hover # nav-bar {
   z-index: 1;
   background-color: rgba (0,0,0,0.8)! important;
}

#browser {
   margin-top: -45px;
}

Any advice to achieve the expected functionality? Thank you

Telling me how to restore it and how to make avoid it happens again. The enclosed picture shows the effect. The blank space is as if it was transparent, as I can click on objects behind them (although I cannot see them, as the blank space is not transparent). It is really a nuance. Are there any shortcuts from keyboard to restore it? Most solutions I read do not work as they say things like "click that button in the menu, or toolbar, or so" but they are simply not there!!!! Thanks for the attention. G

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?
