When I open firefox everything is in the middle of the screen instead of spread across the screen - this started today and is the same if I click new tab - it has the same layout. As far as I am aware I haven't changed anything in settings so either something changed with a firefox update or possibly with a windows update. Any suggestions would be very welcome as it is extremely irritating having to continually scroll down to see things

Downloads on Firefox are slow. They used to be fast, but about three days ago they just went way down to about a tenth of the previous speed. I've tested the same file from the same source and on Edge it downloads at the speed I used to get, so it's a problem with Firefox.

As the topic says, the message list turned from the usual dark-mode look, to a full black background after updating to 151.0.

Was this an intentional change? How can I revert it?

Hello, I have an IMAP acocunt configured, the server is Zimbra and has several shared Inboxes inside my account. Each of these inboxes come with several subfolders (which have the same name in every Inbox), and I would only like to keep some of them displayed in Thunderbird, but the unsubscribe option does not work for a few of them.

I open up the "Subscribe" dialog, I can correctly navigate to the fiolders I want to unsubscribe and click them, which unchecks the mark. I click "Ok" and nothing happens. If I reopen the Subscribe dialog, the folders are checked, as if I did nothing.

Note that I can unsubscribe to most folder, only a couple of them have this problematic behavior.

I have tried enabling/disabling the "Show all folder" option in the Advanced account panel and Enabling/Disabling the local storage for these folders.

I have also tried to unsubscribe the folders, then manually erasing the mbox files and indexes in the account folder before clicking Ok. The msf file are immediately recreated.

In the screenshot, the folders marked with an arrow cannot be unsubscribed, no matter what I tried.

I have followed the instructions for transferring the Thunderbird profile from my old computer to my new computer. However, the updates do not come across. I don’t get all of the folders that I created on the old computer. The email works fine.

Since new update the firefox logo is appearing on my home page and new tab pages, how do I remove it? I changed the setting to false and it still does not go away.

Hello Mozilla team, I am paying for Mozilla VPN with yearly subscription. Should I cancel my subscription with this free VPN? Or where is the difference?

Thanks very much in advance and best regards Karin

I just updated Firefox to version 151.0. The release notes say:

"Private Browsing Mode now allows you to instantly clear all data from your current session without closing the entire window. When you select the End Private Session button (the fire icon) to the right of the URL bar, Firefox will ask you to confirm to clear your session. Once confirmed, it will wipe all of your private browsing data and open a fresh new Private Browsing Mode session for you."

There is no "fire icon" in my toolbar in private browsing windows. I have tried resetting my toolbar to defaults, but that didn't help. I re-installed Firefox 151.0, but that didn't help. I re-booted my system, but that didn't help. I have run out of ideas.

Can anyone tell me how to get this button to appear in the toolbar in private browsing sessions?

I'm using Windows 11 25H2 on a Dell XPS 9630 tower computer.

Thanks, Bill

I have spent 3 hours trying to figure this out. Nothing works for me.

Authentication always fails yet when I log into Outlook it always works.

I turned off using the new hub and was able to setup my email account but it told me OWL was not active (or something about OWL).

Godaddy is my provider.

What am I not doing correctly?

If i want Firefox browser to download the xpi file and save it locally when I click on the download link button for the xpi file, instead of installing it as an add-on. What should I do?

This might sound like a daft question but my excuse is that I didn't set up TB on my PC!

How can I find out from which of my two email providers that I use is feeding my messages to TB as the client? Presumably, incoming and outgoing servers would have to be added at set-up? Is this true for Gmail as well?

Thanks, in advance.

I see "Look for the VPN setup prompt in the top-right corner of your Firefox toolbar. If you don't see it, click the VPN icon in the toolbar." I don't see a setup prompt, and I don't see a VPN icon. What does it look like? Where should it be?

Another message says I can modify the toolbar to add the icon, but I see no icon for VPN.

Windows 11, Firefox 151.0.
