I need to get my centurylink emails moved to thunderbird, ( and keep them in my centurylink for now also ) all folders and contacts if possible. NO IDEA how to start the process here after the initial account set up is done. Please , in easy to understand terms if possible, am computer challenged for the most part.

With the new version of TB the address book has become unusable. It is not White Text on white background. I can't find any settings to reset or apply a theme or fix the colors of the text within the address book. There are many settings and themes that one could apply to the mailbox but if one can't see the address book that pretty much it useless to try to use the email.

How does one just set up the ENTIRE program to apply a theme? Or can we get a working White and Dark themes that address all Text and All backgrounds to make them legible so there are at least useful. TB has become very frustrating. Sorry to rant but before the big changes to use native Darkmode it was really good email client but like so many that try to embrace the darkmode trend (which isn't a bad idea) they are falling short of addressing the entire product.

Any help to address the color issues in the address book would be greatly appreciated.

Sometimes, when I want to use the Take a Screenshot function (on my toolbar) to save a long section of a page, after selecting what I want and scrolling down to the Download button, the process positions the page's floating 'identification' bar across the the middle of the picture. Is there a way to set a keyboard shortcut to trigger the download command after making the selection, without the need to scroll down to see the button? This would greatly simplify the process. In some limited searching and testing, I haven't found anything that accomplishes this.

I have attached a screenshot of a page to serve as an example of how the bar is superimposed.

FWIW, this system is still running Windows 7, Firefox 115.22.0 esr.

Let's imagine that I'm trying to access a server on port 80, let's call it http://example.com:80 . I'd like to see if that site is actually active. When I try and do that Firefox instead goes to https://example.com:443 . In my example, that's actually a completely different site that I do not want to access (for completeness port 80 is used for certificate renewal of a whole bunch of different names that are all set up on other ports, of which 443 is one).

In both a regular Firefox browsing window and in a private browsing window, Firefox decides to access https://example.com:443 instead of http://example.com:80 , despite me explicitly typing "http://example.com:80" in the URL bar.

How do I prevent Firefox from doing this when I explicitly request an http site?

Aloha, I have been using Thunderbird since decades. Since a few weeks (or even months) by now, it is hanging all the time. Meanwhile it is totally impossible to use it properly. Whenever I klick on something it hangs itself up and I have to wait at least a minute until I can click something else and then it hangs again.

I already tried reinstalling, but that didnt change anything. Of course I also rebooted the computer.

Why is that so and what can be done?

Is there a working way to move tabs to bottom currently?

This was working until the latest Firefox update and I do not specifically remember how I had changed it last time but I believe it was via the about:config settings page but I no longer see such an option there. I tried achieving this via 3rd party plugins/extensions for Firefox but not a single one worked for the current version of Firefox. I even tried using the UserChrome.css file, as I found an article about this in the forum but it did not work either.

In the attached screenshot I have shown what I have currently and what I used to have and wish to set again if possible.

OS: Firefox version: 136.0.4 (64-bit)

I just tried creating a new profile in Nightly, and I received the "Approve sign-in to Firefox" email with a code, twice, but the profile page kept saying that my email bounced or something. Now it's saying it's locked.

I used to be able to make my own settings in Bing, but since the last update my settings are no longer stored. Each time I change them, when I open a new tab the BIng defaults are used. How do I get Firefox to accept my Bing preferences?

My email host requires changes to connection settings (this is for an existing account), specifically to increase security but also specifying new incoming and outgoing server names.

I have meticulously copied the settings provided by the host for this purpose but Thunderbird will not (cannot?) connect to the server.

Thunderbird is not asking for my password, nor does the password appear in TB's 'Saved Passwords'.

So I tried 'Add Mail Account', entered all the new settings manually, but TB responds 'Incoming server already exists' (presumably because I had already changed the existing account settings?) - see screenshot.

Should I remove the existing account before trying 'Add Mail Account'? Although that would seem unlikely to work, since the existing account with the new settings does not connect.

Support from my email (and broadband) host has been practically useless, so I thought I would ask the wonderful brains on TB forum if they can give me any clue as to where things are going wrong?

Hallo everyone,

after many hours of Google search and trying many changes in the "about:config" section im done with things to try so my last chance is here.

The problem i have is that videos dont play if i mouseover the firefox window or tab i.E. on the windows taskbar. The video will only start to play if i click on the window/tab and that window/tab is the "active" one im looking at.

It worked fine before but some firefox update f***ed this up (and yes the official firefox updates are the only thing that changed), no i dont know which update it was because i didnt recognize the problem right away.

The autoplay option is set to allow media and audio.

The weird thing is that when i open a video in the vlc player and do the mouseover, everything works just fine. So my conclusion is that some setting was messed up on the new firefox version.

Some data of my pc, everything is updated: - Windows 11 Pro - CPU is AMD Ryzen 7 5800X3D 3,4GHz - GPU is AMD Radeon RX 7900XT - RAM is 32GB DDR4 CL16 - Internet is wired connection with 250K speed - Firefox Version is 137.0.1

Sorry for my bad english and thank you in advance.

I want to switch from Outlook and use Thunderbird for our office emails. However there is no way to protect the saved email logins.

When I use a master password, every time the user opens Thunderbird, they need to enter the password but I do not want to give them the master password as it defeats the purpose. Ideally the master password or another setting should protect the saved logins only and the user should be able to login to Thunderbird without additional password.

So this means Thunderbird is not an application to use in office environments?

Hello there. I had to recently wipe my computer on 4/12/2025. I forgot to sync my bookmarks and passwords. Is there any way I can possibly get these back? I don't know how far back Mozilla itself keeps files, I've been told they do but I'm not sure how far back.

Hello,

Recently I have noticed 'Your browser is being managed by your organization. - That being ImportEnterpriseRoots' appearing in settings. I have seen this mentioned by others but as of yet I cannot see if it has been sorted yet. I have uninstalled and it went away, but it has since returned the following day. I Do not have any other anti-virus on this laptop other than Windows Defender so it cannot be that. I will not be using Firefox as default until this is gone, or at the very least know that its safe.

Hello,

I can no longer log into twitch, it says my browser isn't supported.

Before you say anything: I have the latest version of Firefox, I have disabled all addons, cleared all cache and cookies, even tried a complete, clean re-install. I can log-in in other browsers, just not in Firefox. I have disabled enhanced tracking protection as well, didn't work.

Does anyone have an idea?

Firefox tanked everything I had open on my browser including job postings that I was applying to. I can't get them back. I'm so furious beyond belief! Everything I was researching - ALL GONE!!

I get a reasonable number of TEAMS & Zoom invites by email into my Firefox account.

I have 2 questions ...

1. Can I add Google Calendar to FireFox Calendars ..... or vice versa ... so I can add an invite to FireFox calendar and have it show in Google Calendar.

2. Currently if the invite includes an .ics file I can import that into Google Calendar ..... clunky, but works. However many invites do not include an .ics file ..... as the invfite has arrived in FireFox .... can that generate an .ics file ?

I need to use Google Calendar as it provides cross platform support of multiple calendars.

Firefox now requires me to use a passkey to log in to YouTube. I don't have (or want) a passkey. My computer locks up solid, and I must reboot when I cancel the request for a pass key. I have cleared the Firefox cache and cookies. Nothing seems to help.

Is there any person out there whether from the FF Staff, Developers, Community or End-Users who know how to resize the latest grotesque FF Interface of the latest download version 136.0.1? All my extensions have disappeared. The side bar is too wide. Both the Tools and Menu bars are grotesquely wide.

What is the point in Mozilla FF asking for Feedback End-Users, Community, to Contribute. if it is not going to take on board their views?

Please, do not leave this matter just to the public to deal with, You FF should deal with it for it is your product.
