I am on a MacBookPro running MacOS 15.5.

My FireFox automatically updated to 139.0.4 on June 10th. Since then, my ability to access the internet with FireFox only has been intermittent - I can connect for a variable number seconds and then it disconnects for minutes or hours. I have no problems connecting to the internet with Chrome or Safari, or with other applications. My perusal of the forums leads me to believe that it is the latest update that is causing the problems.

Has anyone experienced this problem and/or does anyone have a fix? Thanks in advance.

How can I stop Thunderbird from displaying its own advertising/donation page on my browser when I open Thunderbird? It opens this page on my default browser, no matter which is chosen: https://www.thunderbird.net/en-US/thunderbird/128.0/whatsnew/?locale=en-US&version=128.6.1&channel=esr&oldversion=102.8.0 If the browser is not open, it will open it.

This is the result of trying to keep Thunderbird from automatically upgrading. In newer versions, the option to choose not to upgrade has digressed from difficult to not available. It did such an upgrade, so I de-installed and reinstalled my original version, only to have this issue.

I was very satisfied with my old version AND see no need for new any of the "features" or look. And, especially, once such a setting is made, don't want Thunderbird, or any other application or app, changing it back. This is a violation of privacy at best.

Worse yet, Thunderbird is attempting to penalize the customer for making a choice on their own computer by infecting the machine with nuisanceware.

Dear Support Team,

I'd like to understand the design of S/MIME signature / certificate validation in Thunderbird. Lets's assume the scenarion that a message with valid signature has been received but the certificate expires very soon (next couple of days).

In my opinion, the behaviour of Thunderbird might be a bit missleading. As enclosed, S/MIME information says that certificate is untrusted, which is not really accurate. The certificate was trusted when the message has been received but now expired.

I assume that Thunderbird validates certificate only against current date. But we have the message original date in the headers. Validation process could be configurable, like in popular pdf readers (which date to use for validation), or even better it could execute 2 validations in case current date validation has not been scuccessfull and S/MIME information could cover this scenario that the signature has been valid while message been created / recived but the certificate expired. It would definitely reflect real scenario in more accurate manner.

I'd appreciate if you could let me know if there is a configuration possibility which I'm not aware of. In case it is not available, can you please advise how I could submit a proposal of functionality enhancement? In case, there are rules comming from RFC standards restricting the validation of signature in a way that has been described, I'd also appreciate this feedback.

In spite of the above remarks, I think that you did a vary good job with S/MIME functionality in thunderbird. It is far more user friendly and well presented to a user than in other email clients.


Best regards, Marcin

When I didn't know what I was doing, within Settings for Firefox desktop browser for Windows 10 where you can make associations for file types or applications, I began putting choices in that I felt made sense at the time. I don't think I've made the best choices and I would like to change that entire section with the heading Content Type to the defaults that would have appeared in the Action column. Is there a way I can return the defaults only for Content Type without resetting everything in the browser to the state it was first in before I began customizing some areas? Thanks.

Hi Team,

Why can't I disable the Search Tab option that is annoyingly cannot be removed in the Customize Toolbar option? Also, why isn't there a settings option to adjust the size of the tab height? Also, instead of mentioning as "Playing" at the bottom and thereby making the tab height bigger why not just show a sound icon before the tab name to indicate the tab is playing some media?

Also, kindly if there is a way to continue extending the support for ESR, that'd be great

Is there a setting where you can set a timeout for access to passwords so when the time limit it is up it forces you to re-enter your master password to gain access when on a page asking for credentials? Currently I login with my master password and every site I go to Firefox will have my passwords ready to use, even if I leave my computer on for a week. How about a four hour timeout. After four hours and I go to a site asking for my credentials, Firefox will prompt me for my master password before letting me access the vault?
