For the 3rd time in the past 10 months, I cannot receive or send emails through Thunderbird on my laptop. Again, a pop-up states IP address is temporarily blacklisted and another states cannot login to imap.comcast. This always happens after a Thunderbird automatic update. (Last auto-update was Jan. 22, 2025. Haven't been able to access Thunderbird email since then. Have checked settings and all are set as required. Have reset modem and router. Have deleted all junk emails. Know it's not a Comcast issue as I am getting my Comcast emails on my cell phone via my BlueMail email app. (But cannot work on emailed documents on my cell phone.) The other 2 times this happened, email began loading after 10 days of no activity. No rhyme or reason. Have checked the box for a status update but reports come through via email... which is currently not accessible via Thunderbird. Why does this continue to happen? Please help!

I accidentally updated thunderbird and now all my individual folders have disappeared as well as my address books. It also redownloaded 886 messages dating back to 2022!! Help. I really need my sorted folders back and all my addresses.

I am got the following message from Biddefender when I accessed my BoA site: firefox.exe attempted to establish a connection relying on an unmatching security certificate to bankofamerica.com.data.adobedc.net.

What does this mean???

Dear Mozilla, I work as a seniro advisor within internet intelligence and investigations at the Swedish customs. I wonder if it is possible to get BSI ( basic subscribe information) from you and if you in that case can provide a link or an email address for our request. What kind of information would you like us to provide.

Looking forward to your reply.

Kind regards, Gabriella

Hi,

I put some messages into folders yesterday and then created another folder and dragged the first folder into it to become a subfolder.

When I did this, I saw the new folder but it couldn’t be expanded to show the subfolders.

All other mail clients showed the correct hierarchy except Thunderbird.

Why is this happening?

Secondly, I post comments on the thunderbird blog regularly but they never show up. Where are they disappearing to? Are you receiving them?

I've been having issues with Instagram not loading properly on Firefox. Sometimes images and videos don’t appear, and the site feels slow compared to Chrome. This makes it frustrating, especially when trying to engage with my audience and grow my Instagram followers.

I’ve tried clearing my cache, disabling extensions, and even updating my browser, but nothing seems to work. Is this a common issue with Firefox, or is there a specific setting I need to change?

As, I run a business, where people can buy Instagram followers to give their profiles a boost. People often ask questions about services on Instagram DMs. So, having Instagram work smoothly on all browsers is important.

Has anyone else faced this problem? Any fixes that worked for you?"

Using group policy there is various settings required for our users. We have been using the preferences policy located at: Administrative Templates > Mozilla > Firefox > Preferences

This policy requires the use of JSON, we have been using the following which has been working ok:

{ "media.navigator.permission.disabled": { "Value": true, "Status": "user" }, "browser.warnOnQuit": { "Value": true, "Status": "user" }, "keyword.enabled": { "Value": false, "Status": "user" }, "browser.tabs.unloadOnLowMemory": { "Value": false, "Status": "user" }, }

Within the old "Preferences (Deprecated)" there is a setting called "intl.accept_languages" which we are wanting to use but I can't seem to find a way to include this within the JSON. We are wanting to set it to "en-GB".

If I enable this within the old deprecated preferences section it causes the Preferences with the JSON to stop working.

I have tried various combinations of including it within the JSON but neither are working:

"intl.accept_languages": { "Value": en-GB, "Status": "user" }

"intl.accept.languages": { "Value": en-GB, "Status": "user" }

I've checked the Mozilla website here: https://mozilla.github.io/policy-templates/ There doesn't seem to be any reference for the intl.accept_languages setting to be used within the JSON

Please can someone advise?

I were not sure, where this could belong, therefore I chose "Settings".

I recently switched from K9 Mail to Thunderbird Mobile and were very happy to see, that there has been a migration option to transfer all the account settings from desktop to mobile version.

Well, not all accounts and not all settings were transferred and only the first QR code has been recognized whereas the other three were unrecognizable - but still a good move!

That brought me to the idea: Wouldn't it be nice, if there were some Thunderbird Sync, where all accounts, the server settings, the identities (!!), the signatures (!) and other settings (fonts, quoting etc) would be the same on all devices?

And where would be the place to promote such an idea?

Last update Version: 135.0.1 (64 bit) Since I upgraded, all cloudflare robot verifications are not passing. It constantly redirects to the verification page. For this reason, I started using a different browser. I go in and test it from time to time, it is still the same. Update. Fix it.

Note: I reset the browser. I removed the add-ons. I reset the proxy. Cache was cleared.

Result: It still does not pass cloudflare verifications.

Hello

Overnight Thunderbird has developed a major problem. The count for the number of mails in a folder is correct, as best I can tell, but when I open the folder it is either empty or has fewer mails than the count. Based on several tests, repairing sometimes adds more mails, sometimes not, but never the entire folder.

I repaired the inbox and it is now showing several mails that I deleted in the last few days (by emptying the delete folder having previously deleted them). Curiously, they’re all the same type, routine mailings about road works.

I may have backup in that I copy the entire Thunderbird folder to an external drive every morning, including today, and to Google Drive every Wednesday.

Please can you help.

Thank you
