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

After the last update to Thunderbird 139.0.2 on a windows 10 computer, the write button doesn't work. When I click it nothing happens. I receive messages and can even reply to messages I just can't write new messages. The error console shows an error: 1750426957343 addons.xpi WARN Checking C:\Program Files (x86)\Mozilla Thunderbird\distribution\extensions for addons UnknownCollectionError: Unknown Collection "thunderbird/moz-essential-domain-fallbacks"

I think I have turned add-ons off and still have the problem.

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.

I can only open my emails by right clicking it and opening in new window. Also keeps asking for password every time I go on Thunderbird. Have tried solutions on the help pages and online for both problems but not much use. Some things on account settings and security are not there to select. Is it correct that if I uninstall Thunderbird and then reinstall it the same problems will be present?

For the 2nd time in 3 months my history and password files have disappeared from my browser. I have an Acer laptop running Windows 10 with Norton Security. I've tried a few fixes from your site with no success. Also tried a fix your site did have, but the link led nowhere. I need these passwords back. What do I do? I was in the midst of registering my wife for social security. Now my login and password are in the wind. Please get back to me Thank you

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

There is a black box on the top left corner whenever firefox is maximized. This problem appeared when I got my new computer screen (Asus 27" TUF Gaming VG27AQ1A, 170Hz WQHD). My old computer screen (23.6" VE247H LED, Full HD, 2ms, 10M:1) didn't have this issue.

Any help how to fix this issue?

I'd like to ask about Firefox's behavior and settings. I'm using Firefox with vertical tabs (using an add-on), but it seems to be behaving strangely. The things that have changed since before are: 1. Open from pinned tab 2. Now opens in a new tab → Previously it opened in the same tab 3. Clicking on a newly opened tab opens a new tab again → Previously it would open pinned tabs/same tabs → in a new tab It has changed. I haven't changed any of my Firefox settings. Windows 11 Home 23H2 Firefox version 139.0.4 (64-bit).

So, I recently encountered this problem: If I close the main Firefox window while a private window is open, then when I open a regular Firefox window, I find that all pinned tabs have been reset, and I have to set them again.

This problem has never happened before, so I figured it was clearly a new bug and I should report it.

I asked a friend, and yes, he also encountered this problem.rt it.

firefox not discarding tabs automatically even though i have tab discarding on in about:config via "browser.tabs.unloadOnLowMemory=true" "browser.tabs.min_inactive_duration_before_unload=60000"

also if i discard them manually from about:unloads manually whenever i restart firefox all discarded tabs come back to life is it supposed to do that?

Thanks

Firefox cann't use microphone in my android 5.1 device. But a camera work perfectly (after confirm allow in a pop-up with asking "if you want to share your device’s camera and microphone with that site.") FireFox detect microfone as "default input device" but it doesn"t work. In a special sites that can test a work of the microphone, drop down list of the detected device (in the Firefox) contains only one item "default input device" and microphone doesn't work. In other browsers (Chrome), вesides this "default input device" that drop down also contains other items and microphone work perfectly I need to use microphone in Firefox for web version of a messenger that doesn't support in ohter browsers and apk on this android device

I have been attempting for two days to sync my Firefox desktop info (for the bookmarks) to my iphone, and it keeps coming up with a 500 error - see attached.

Please advise as I'd like to have my bookmarks the same in all places. I have an iPhone 11, and as far as I know all versions of Firefox in both places are up-to-date.

Thank you.

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?

Please I want to remove Ai from Firefox Mozila permanently on Windows 11 for all users/profiles:

I tried a lot of workarounds but they are unsuccessfully: I tried to create extensions (Hide Gemini, AI Google Overview), but they do not work for all users; only profile-based extensions are supported. I tried to use preferences using internal settings on Firefox, but it does not apply to all users. I tried using a script on PowerShell for all users merging internal preferences, but it does not work I copied the local and roaming settings from Firefox to the Default profile, but it was unsuccessful.

I also tried to remove "All" from the search page, but I moved the seach to go to the tab "Web" only.
