I set up a new Outlook.com account around a month ago. I initially had problems both receiving and sending but resolved that after enabling the IMAP option on the Outlook Web pages.

I have checked the SMTP settings and they are correct, and the connection test succeeds. Sending via the Outlook Web page works correctly.

For reference, I am using Thunderbird 153.3.1esr (64-bit) on Linux Mint.

Hi!

I'm trying to use Widgets in the Home page, but I can't find the option to enable them. Following [previous solved question], I checked that I have the "Allow Firefox to improve features, performance, and stability between updates" option enabled, have restarted and updated Firefox, but I still can't find the option. Should I check for other configurations?

I've set my local open-webui as the browser.ml.chat.provider as https://llm.local/ and upon right click to a page and saying "summarize this" the side bar is opening. But the prompt doesnt get pasted to the webui.

Doing that while the sidebar is already opened works fine!

Any suggestions how to fix this?

For a few days I'm having trouble with Asana mails (notification mails informing me about replies, comments, etc).

Clicking on the mail to view it freezes Thunderbird for a good 5 seconds while one CPU core spins at 100%. This only happens with Asana mails (or at least I haven't found any other problematic senders).

I guess it's a problem with validation or parsing of the mail's HTML content. But I don't know how to debug this.

I can't pinpoint exactly when it started happening, but it was around the time I've switched to the [new snap release track](https://support.mozilla.org/en-US/kb/channel-choices-thunderbird-snap-and-flatpak#w_snap-channel-changes-in-2026). But since this happens with Snap and Flatpak I think the culprit may be the 153.0 update.

Things I've tried:

• Clearing cache and msf files.
• Troubleshooting mode with add-ons disabled.
• Reinstallation. Creating new profile + importing old data.
• Switching from Snap to Flatpak
• Switching Message Body display to Plan Text or Simple HTML.
• Disabling HW acceleration.
• Checking console for suspicious output.

Anything I can do to create handle the problem or collect information for a proper bug report?

I have installed Thunderbird on Linux on a chromebook. When I try to add my (gmail) email account in the Thunderbird account setup screen, it hangs up trying to authenticate the Google password for the gmail account. I have scrupulously checked and rechecked the password and the server details, and they are all correct. Why won't Thunderbird accept the password for my gmail account? Or is something else not right?

When I open many new tabs, I'd like them all to be loaded immediately (as soon as they the new tab is created, a.k.a. eager loading). The reason is that, when I click to actually see those pages, if they are already fully loaded, that will make user experience much smoother.

Please see attached image for a demo of current behavior: browser had plenty of time to load those new tabs in background, but it didn't.

I understand that lazy page loading is a way to preserve RAM and CPU cycles. I know that is usually a good thing for users who are used to working with only one thing at a time and/or have limited hardware resources. However, I think there should be an opt-in feature of eager loading, which would optimize a lot the time for experienced/heavy users.

Thank you!

It seems the sync server is keeping deleted passwords record placeholders ... for ever?? what is the point of this? User tracking?

he same with the credit card records BUT not eg bookmarks.

(server records as I can see using the about:sync extension..)

thanks for any help..
