Thunderbird not connecting to server. It says timds out and an error occurred connecting to mobile.charter.net. I can neither send or receive emails. This started 8/20/2026

How can I log into my account when Mozilla has locked it? You list no e-mail address, phone number, I have spent alot of time today trying to unlock my account? Why would I want to donate $ to Mozilla, when the customer service is so poor? My account username is [email address]. This is also my e-mail address. I would like to get my account unlocked so I can sync my passwords.

Thanks,

Joe

When seaching the browser will show the result for a split second and then crash. This is a private browser and can not be reloaded. Sending an error report to Mozilla.

Hello! Since the latest update to Firefox (153, I believe) my Firefox has not worked. It starts up perfectly fine, but quickly freezes, becomes non-responsive, and needs to be closed. No matter how many times I attempt to open it, the same thing occurs. There’s been been occasions where it hasn’t frozen immediately so I have been able to turn off hardware acceleration as well as remove my theme and disable all my add-ons/extensions, but this has done nothing. Creating a new profile does not help, nor does trying Safe Mode: the same thing happens no matter what. I tried to reinstall the update, but this also did nothing. I haven’t yet tried to uninstall & reinstall or do a Firefox refresh as those are my last resorts and I won’t do them unless I’m sure they’ll make a difference. I haven’t downloaded any new extensions recently, and this only started happening after the most recent update. I’m not sure what else I can try at this point, and am very frustrated.

For the past several days, TB has not been downloading messages from Yahoo. When I click to download, it will say "downloading message 1 of 36" and then time out.

I get this message when I double-click the progress bar: "Connection to server pop.mail.yahoo.com timed out."

The settings have not been altered in any way.

I've looked through the various discussions on similar questions in this community and on Reddit, but none of the suggestions have worked.

Help please.

Since yesterday (27 Apr 2026) any and all mail that comes into Thunderbird gets marked as SPAM. I searched online and found people saying that I could reset the junk training filter, so I did this, but incoming mail was still marked as spam. The next suggestion was to delete the training.dat file. Did that, restarted Thunderbird and incoming messages are still marked as spam. The last suggestion was to turn off adaptive junk mail controls. Didn't want to do that because I assumed that it would let spam through. Nope. Turned it off, restarted Thunderbird and two emails from my work came in and got flagged.

I'm running version 140.10.0esr (64-bit) on Windows 11. I am using IMAP to connect to the mail server but it's not running any spam detection software (like Spamassassin). I know this because it's my server and even if it was, no updates have been preformed since the first of this month and this just started happening yesterday. Combine this with the bug that Thunderbird notifies me of incoming mail, even if it's spam (didn't post about this because there are plenty going back a couple of years), is starting to make me look for an alternative.

For the past few days when trying to use Google search on Firefox I get this message:

"Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot. Why did this happen?"

Then it makes me jump through several hoops to do a search on google.

This is a Firefox specific message as I can switch to Safari and there is no roadblock.

Is this happening to anyone else?

Any way to resolve?

Why this is a Firefox issue and not other browsers?

I want to use Thunderbird for transferring email folders from my Yahoo email account. I have no idea how to do this. Simplify, please. Not computer savvy. Thank you in advance

I already have View > Sort by > Date is selected, View > Sort by > Descending selected, and thread sorting set in settings. See screenshots. Threads sorting so newest is at the bottom, they should be at the top. General emails are sorting properly, newest at the top.

We are facing a critical printing issue with Thunderbird 154.0 (64-bit).

Emails are not printing from Thunderbird and are coming out as completely blank pages. However, the same email/file prints perfectly when saved to a folder and printed from there. This confirms that the printer is working properly and the issue is specifically with Thunderbird.

The problem is affecting multiple systems in our office as well as our Ahmedabad branch, which is seriously impacting our daily work.

This issue requires immediate attention. Please investigate and provide a solution/workaround at the earliest.

I have no desire to interact with Google, Bing, or Perplexity, and as a rule I don't want outside parties (such as Firefox/Mozilla) deciding for me which search engines or other service providers I see advertising for. (And yes, seeing that "G" logo somewhere is advertising for Google.) I'm assuming that these companies are paying to be pre-loaded as search providers in Firefox, and I understand that Firefox needs this financial support if it's going to continue providing a browser.

After upgrading, I've always gone into the settings and removed these search providers - I don't want to see them offered as search options, and to be honest, I don't even want to see their names in the settings screens.

Now with Firefox 152, I find that I'm not able to delete these pre-loaded search providers anymore. I can turn off a switch to disable them, but there's no way to totally delete them from the list anymore. There's even a [in the documentation] which explicitly says that the pre-loaded search providers cannot be removed, only hidden.

'WHY can I not delete them?

Is there a technical reason, i.e. would the browser stop working if they were removed? Are some companies paying extra to not be delete-able, and it just happens that every one that's pre-loaded in Firefox 152 decided to pay the extra money? Or did Mozilla just make an arbitrary decision to reduce the level of control that users have over their own browsers?
