I successfully imported the self-signed CA certificate into thunderbird. Then I tried to import the p12 S/MIME client certificate and this error message popped up (cf. screenshot below).

However, I checked the client certificate and it seems fine:

1. openssl pkcs12 -in smime-client-certificate.p12 -info -noout

1. pk12util -l smime-client-certificate.p12

What is going on and how to troubleshoot this issue as there is no logging about this matter into /var/log/syslog?

Environment: - Ubuntu 25.10 - thunderbird 2:1snap1-0ubuntu3

You jerks deleted passwords and bookmarks I needed for work just because I reset my password to login. Why in gods name would you think that's a good idea? Why would I ever use your sync function if you're gonna delete my data the moment you get the chance?

The autofill card details isn't working. When I try to I get the message "You have no saved cards."

When I go into the Privacy & Security tab I can see that I have a number of cards saved correctly.

I have my browser.sessionstore.max_windows_undo in about:config set to 60 – it's been like this and working fine for several months.

It's set to this high number because I use an assistive technology which creates a fresh pop-up every time I deploy it, and Firefox treats it as a browser window closure when I close the pop-up. Consequently, I can easily rattle through well over 25 window closures in a day.

It's not necessarily that each window contains dozens of tabs and copious data, but nevertheless Firefox still treats it as a window 'within the meaning of the act'!

I just went to reopen one closed window from a couple days ago which did contain many tabs (partly why I closed it in the first place), only to find that the 'recently-closed windows' context menu is now only showing 20 windows (18 of which are the aforementioned pop-up assistive technology windows)

The really vital window that I want to reopen is not showing.

I've double checked in about: config and the browser.sessionstore.max_windows_undo is still set to 60 windows; nothing has been altered or reset.

I updated Firefox to 147.0.4 yesterday evening, but the problem existed before I updated Firefox, and is still in evidence since updating.

Two questions:

1) Why is the Recently Closed Windows context menu not showing the full number of windows it has been successfully doing with no problem now for months? I used to have to scroll down to access the full extent of the 60, but they were always there.

2) Why has it arbitrarily changed to 25 windows?

3) [I lied – Our chief weapons etc...] Is there a way that – given about:config still implies that the most recent 60 windows are retrievable – that I can access beyond the 25 windows limit that are currently showing as reopenable?

Thanks very much

(And yes, I already have things like OneTab and Tab Session Manager add-ons, but disabled those just before closing the important window, because I was trying to locate which add-on was draining the CPU. I assumed my 'recently-closed windows' buffer of 60 would suffice while I disabled the add-ons.)

I can't access Bookmarks anymore, I have many saved sites and I can't find them anymore? What can I do? My configuration has completely changed and I don't know where to start? I can't even translate with Google, it keeps stopping

Up until today I have never had trouble accessing My [edited from community support forum] @deamer.org address for the Deamer.org website But to day I am completely block our by Fire fox for even getting to Deamer.org and I get this message Did Not Connect: Potential Security Issue

Firefox detected an issue and did not continue to 408916.svc.e1m.net. The website is either misconfigured or your computer clock is set to the wrong time.

It’s likely the website’s certificate is expired, which prevents Firefox from connecting securely.

What can you do about it?

408916.svc.e1m.net has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.

Hi! So I have Windows 10, but don't know if that's what's causing these issues. Certain websites, that is, Instagram, Bluesky, Youtube, Yahoo, Facebook, and Norwegian news site NRK, as far as I've seen, are not loading properly. Insta and NRK are in simple mode, no matter how many times I refresh Yahoo initially says "failed to load", then resolves itself upon refreshing, but it's really annoying to have to refresh for every message and going back to the main inbox Youtube videos are stuck on the spinny wheel of death, and along with Reddit, one other symptom is that the profile pictures won't load. Reddit posts also won't load beyond the first few, and "continue thread" doesn't do anything Facebook won't load at all, still nothing as I refreshed just now. Bluesky, I'm not sure is Firefox's fault, or what, but I get the "Oops network error", at least on one user, it turns out, but not another, nor on Bluesky main page (I swear, it sometimes feels like at least Meta has something against Vivienne Medrano, because I was also having issues with Insta not showing posts in full screen mode before this became an issue, and it was only majority Hellaverse accounts that had these issues. The Bluesky account that won't load is also a Hellaverse account. Either way, that's not here nor there regarding this issue)

What on Earth is going on?! Is it that I have too many tabs? I do have around 1000 tabs, which I guess could be an issue, but it hasn't been until today, two or so hours ago. I was even fine last night! Is 1000 the limit, or something? I do have some ad removers, which btw, some other video watching sites suddenly won't load the videos unless I turn the adblocks off, not cool

Please respond quickly, I am losing my mind here /halfjoking -Helene

Good day! Initially, I installed Firefox version (x64 ru) 147.0.3. After updating via the "Help - About Firefox - Update" menu, I received version 147.0.4. However, there are two entries about installed Firefox in the Windows section "Installed applications": 1. Mozilla Firefox (x64 ru) 147.0.3 and 2. Mozilla Firefox (x64 ru) 147.0.4. Although one instance of the program is installed. How do I remove an extra entry? Thank you.

PS: I have Windows 11 Pro 25H2 (26200.7840, 1000.26100.291.0) Russian CPU AMD Ryzen 5 5600X 6-Core Processor RAM 32,0 ГБ System x64 Video NVidia GeForce 1650

... just that. Actually I wanted to print a selection, but if the selection is longer than one page, only one page will print. So I thought if I could save the selection to a file, and then print that file, I'd solve my problem.

Greetings. Am running Firefox 147.0.4 (aarch64) on a MacBookPro running Mac OS Tahoe 26.3. When I first launch Firefox, it sits and does nothing for 30 to 45 seconds, I have it set to open a National Weather Service forecast page at startup, but even if I try to type in a different URL, Firefox won't allow me to do anything --or even quit the application -- until that first web page finally loads. Have tried clearing all history, including cookies and site data, but that does not help. The hangup was even longer until I worked with Apple tech support to turn off some universal add-ins like Content Barrier (Intego) or anything that acted like a VPN. Apple told me the hang is apparently caused by a Firefox add-in or extension. But I can't figure out how to find any or how to turn it off.

I have a Hotmail account and multiple gmail accounts. When I try following your (obscure) instructions for changing passwords, the box of passwords is only for my gmail accounts. None for my hotmail.

As Hotmail is very important to me, I'd like to keep accessing it through TB but you make it tough.

I am now not receiving my Hotmail mail and as I get too much traffic 200+ msgs a day, it will build. Please send simple, direct instructions on how to find and change the hotmail password, thank you.
