I'm having trouble opening urls in a private window from the command line on Windows 11.

Firefox version: 144.0.2

Starting a new private window works fine with "C:\Program Files\Mozilla Firefox\firefox.exe" -private-window

But doing: "C:\Program Files\Mozilla Firefox\firefox.exe" -private-window "https://www.google.com"

just opens the link in the last selected window if the last window selected is non private it just opens the link there instead of a new or existing private window

I have also tried with no success: "C:\Program Files\Mozilla Firefox\firefox.exe" -private "https://www.google.com"

What should happen is that the main image should change on mouse hover over one of the images from the column on the left. Also it should be possible to use the left or right navigation arrows on the main image to cycle through the images. Neither of these actions is possible. It works fine on Edge.

This one is puzzling to me: On a website with login, whenever I click on an link to a pdf, a new tab opens (my normal setting) and immediately crashes (not my normal setting ;)). However, everything is fine elsewhere on the web, even on the same site in the sections without login. Here are some observations that may or may not be connected to this:

• If I right-click and open in new tab/window/download, everything is fine
• When I return to the tab where I clicked the link, the page reloads - independent of whether I did anything in the crashed tab
• the site-admins were not able to reproduce the problem, also it seems fine for other users
• the problem persists in troubleshooting mode, also manually disabeling extension did nothing, emptying cache etc. also nothing.

It is not like this is making me switch browsers (although no crashes in edge), but it bothers me to have no idea why this is happening. :) Maybe someone here feels the same? Thank you for reading either way!

To be clear, I seriously doubt the problems I am encountering are TB's fault! The problems may be my fault since I've grown older, I've tended (believed) using new versions of software present my mind a BIGGER challenge than using the older software/version I have been successfully using? I'm still using Version115.10.1

After our ISP chose to start using Zimbra Oct. 7, 2025 and their tech support could not assist me in getting TB working the had me remove POP3 settings for TB and change to IMAP with their software.

FINALLY someone helped me get TB working with IMAP. For 3 days grrr. Now the ISP says I need to use their web mail, Zimbra.

So might downloading the current TB version and somehow get the In box, all the folder contnets etc. over - into the new TB help?

I was going to backup everything tonight, now I have little to NO hope, without help!

THANKS & remain WELL plus be SAFE!

I changed my password.......still not letting me in....so I changed emails....I'm confused.....I want to know did my new pc accept my change of passwords from my older computer?

Hello, I received an email from Spectrum (.TWC) that I needed to change my password by Nov. 11th. I did change it last evening. Now today I cannot receive my email via Mozilla Thunderbird, I receive the pop up to Enter the Password when I open it. Can you help me with this. Thank you for your time and efforts.

I just installed Thunderbird on a new Win 11 Pro 64-bit install. I have some Message filters that seem to be working. However, I have a local folder a_Name and under that I have sub folders Problems, jokes, plus some more. At first, I tried to drag messages to them, and they disappeared. Then I tried to use the file move command still disappeared, then I tried to use the copy command. That worked until I tried to move a message to the folder, and everything disappeared. I have now lost some irreplaceable emails. I have used Thunderbird for years. What gives with this, and how can I fix it?

Hi there, I am having a problem with Squareup sign in. I am using firefox for a very long time, never had problem. The error message is "internal error" Any solutions? Thank you

On all three computers, I have "Always ask you where to save files." On all three computers, it never asks and always stores in Download.

On my work computer, Outlook's problem is that all hyperlinks open in browsers while we use Sharepoint links. I want the pdfs to open in Acrobat. I've changed the Applications section, just below Downloads, to use Acrobat for pdf files. I was hoping that would mean Outlook would tell Firefox, my default browser, to open the pdf, FF would see it's a pdf, and it would open Acrobat. That's not happening.

Any clues how to resolve either?

When I log into a website, say amazon.com, and it prompts me to add a passkey, my only option is local windows machine.

If I use Chrome, I can choose between Google PW manager and hardware key.

Once I save the passkey in Chrome, it works just fine in Firefox.

Is this expected behavior? I used FF for personal browsing and don't really want to move to Chrome.

How can I stop my tablet from opening a new tab every time I switch to Firefox? It’s the worst when I’m trying to get information quickly into another app. I’ve looked through all of the settings and it’s not there. I’ve tried typing about:config and it does nothing except show the new tab window.

Someone please help. I’ve seen an answer from a question about a decade ago but things have changed now and there is no “options” if that’s the next suggestion. All I see is Settings now, and no options to change this in there either. This should be obvious right?

I have several problems with Thunderbird:

- When I first open TB, my Inbox shows "No message found". I have 9654 E-mails in the Inbox. If I click on a different folder and then click on Inbox again, I can see the E-mails in the Inbox. - About once a week when I first open TB, the program begins downloading 10000 E-mails (sometimes more). All these E-mails, with the exception of a few received the previous night, have already been downloaded. This download takes as long as 45 minutes. - TB marks many E-mails as Spam even though I have previously marked these E-mail addresses as not Spam.

Any help with these problems appreciated.
