I don't know what to do when February 29 is in my calendar, 2026 is not a leap year. I've found nothing to help me. I have the latest version if Thunderbird. Thanks

These icons appeared recently in my Firefox browser I can't remove them. The only recent changes included uninstalling SuperAntiSpyware after finding that Microsoft PC Manager is a better option, which has performed excellently without issues.

Additionally, a free VPN (Proton) was briefly used from the Firefox browser without installation, but after finding it complicated to set up, it was deleted. A few hours later, I noticed the two icons as the windows were misbehaving and they are causing a slowdown in the PC's performance. They do not seem to be add-ons or extensions.

How do I remove the icons and return to the previous performance?

I have just had to replace my PC following a bit of a disaster with my old one. The new PC has Windows 11. As usual I downloaded Firefox as I always use this. Somewhere in the installation of Firefox I must have been asked about blocking ads, but I don't remember. Now all ads are blocked, which I don't mind, but some sites are asking me to disable my ad-blocker if I want to use their site. Mostly I don't but there is one I need to use, so I would like to add that site as an exception, but I cannot find any mention of any ad-blocker in settings. Where do I find this? and how do I add exceptions?

The only add-on that I have in Firefox is the 'Privacy Badger' which could be the problem I suppose, but I can't see the website listed in the ones Privacy Badger is blocking.

Any help would be appreciated

During recent update 148.0 (64-bit) google calendars are not shown either in "Events and Tasks/Calendar" or in "Today's Pane".

Subscribed calendars are still there, but nothing is shown in the days/weeks/months entries apart from the first calendar in the subscription list! Nothing else. And nothing in today's pane.

Reinstalled Thunderbird and reinstalled "Provider for google calendar" but nothing changed.

Thanks, GG

Issue

Thunderbird fails to wrap long lines of HTML-formatted text that is wrapped in a <pre> tag. This behavior is consistent in both the email viewer when viewing received emails, as well as in the email composer when writing an email containing preformatted text.

What I tried

1. Make all settings of config editor that contain the word wrap as true 2. make a userContent.css stylesheet within the chrome directory within the profile directory.

Question

How do I post the offending HTML code (and the CSS file I tried) on this forum?

How do I force Thunderbird to wrap preformatted text?

Not sure how it happened but I've suddenly lost access to my Google calendar. On the bar on the left side of my calendar display screen there is a list of two calendars, Home and my email address, which I think is a Google calendar. Even though I check "Show all calendars" it does not show my email address calendar. And if I click on only to show my email address calendar it shows nothing at all. On my Pixel cell phone I can still see both the Home calendar and the Google calendar, so I guessing Thunderbird has just lost the link, although it shows a googleapi address when I click on properties. When I accept a Zoom calendar listing it has always and still shows up on the Home calendar. This seems most mysterious. Anyone have an idea of what I should do? Is there anyway I can rebuild the link to the Google calendar?

I am helping a friend who has a problem when opening any browser software on an old laptop so I cannot operate the syncing option. The old laptop uses Windows 10.

I want to transfer (to new laptop running Windows 11) the history, bookmarks and passswords by copying from users/hername/AppData/ but do not know which files need to be copied

When I tried to log in to my account earlier today, I found that it was gone. I used my recovery key to create a new password and now lost all data, passwords etc. What do I do now? Why did this happen? I am not very computer literate but have tried all of the suggestions in your help forum and nothing works. Nothing has changed on my computer since my last login yesterday. Firefox is my home page and browser.

I am trying to add a business gmail account to my Thunderbird on Desktop and have run into difficulty.

I tried to use This Article in order to overcome the issue, however it is dated 2018 and seems very out of date with the current UI. So I am struggling with how to rename the incoming/outgoing servers to allow the new gmail account into the host.

When I try to add the gmail account I get the window to sign into the new account, but when I click continue I get "The server cannot process the request because it is malformed. It should not be retried. That’s all we know." (see attached image).

Escaping out of the log in screen brings me back to the config page which appears to have accepted the account, until I hit continue and then it tells me that the incoming server is already in use. (see the second image).

I also tried turning off the experimental add account and use the previous interface to work the problem. I got the same results both times.

Please advise, I'd really like to have access to the account emails on my desktop without using the google web interface.

Thank you DD Randall

I am running Firefox 148.0 and Thunderbird 148.0. I am in the process of moving everything to a new (to me) computer that will run Windows 11. When I start Firefox from the start menu or the taskbar everything runs as expected. I have the Adblock Plus extension plus several others running. If I click on a Hyperlink in a email in Thunderbird instead of opening in a new tab into the currently open copy of Firefox as it did on my old computer running Windows 10 it opens in a new window with no extensions. I am assuming that I have something set incorrectly. Any help as to where I should look to fix this issue would be greatly appreciated.

Today my goggle searches, are being sent to the address bar, and have the google tag in front of them, I cannot use any of the other search engines that drop down from the upper search bar, so just google, and that is really hijacking my search.
