I want to create a list of allowed web sites in settings/cookies&data/manage exceptions, but it seems I have to enter each site MANUALLY. I would like to do this more quickly and easily by just selecting sites in the "manage cookies" list and designating them as exceptions. Or is there already some other way to do this that I haven't found? Also, after I have made exceptions for all my important sites, by whatever means, can I assume that I can press "delete all" in the "manage cookies" list and the allowed sites will not have cookies removed? What happens to exceptions if I select "delete cookies and site data when Firefox is closed?" If there is no way to make exceptions other than manually, I respectively request that some convenient method be added to the program. Thanks for any response.

I'm using Thunderbird 115.7.0 (64 bits). Cannot send messages from my email account: katy.vandenhoek@gmail.com. It says it cannot make connection to server smtp.gmail.com. Receiving emails is OK. The other emailaccounts are working OK. Looks like there is something wrong with the authentification. Reïnstalling Thunderbird didn't help.

I am on endeavourOS (linux). Whenever I try to upload images for a profile picture to sites like youtube or X, the image becomes corrupted and doesn't upload correctly. It did this with whatsapp too and I had to use a separate app for it. Other posts said that disabling "privacy.resistFingerprinting" would fix it, but it's already disabled.

Attached below are an example of this bug and the contents of this image when viewed on a text editor.

Recently my Thunderbird started asking for my passwords every time I opened it (I have multiple Hotmail accounts). After I added the passwords it would keep asking for them over and over again (they were ALL correct). I have now uninstalled and re-installed the latest version of Thunderbird and only added 1 account back in and it still keeps doing the same. The password is visible and correct in the saved passwords section. I am now having to use another client (Outlook,which works correctly, but isnt a patch on Thunderbird) Running MACOS 12.7.3 Any help would be greatly appreciated.

The page https://support.mozilla.org/en-US/kb/ai-chatbot lacks the list of data shared with the chatbot AI providers. It would be nice to know how it is done, how to review the data, and how pages can provide better data.

Now that Mozilla/Firefox have joined Google on the dark side, who is everyone switching to? I would like something that works well in both Windows and android. I hear Opera can't be trusted and I don't like how there are like 6 difference versions of Opera in the android app store. DuckduckGo is just badly made IMO. Edge causes some glitches with one of the sites I use most. Should I try Brave? I just want a browser to BROWSE the web. I don't want AI. I don't need a VPN or adblock built in. I don't want a "gamer" browser. A decent local password manager would be nice but I don't want to have to make an account to use it. I know if the product is free, you are the product, so I would almost prefer a browser you pay for but oddly that doesn't seem to be a popular option. Probably because the user data the companies collect makes them more money then people would be willing to pay. Sad times. I miss the 90's.

Hello,

Ive installed a MIME-certificate from Sectigo in Thunderbird 115.6.1 on Pop OS (flatpak).

The cert is in a pw-protected .p12-file which I have imported successfully. However when I try to sign emails I get the error-message shown in the first attached image. That the application cant find my cert or that it has expired. Both statements are incorrect imo :)

In attached image 2 and 3 it shows that the application has imported the cert and that its valid until 2025.

Any tips or input is helpful.

Also under Security Devices I have a PKCS#11 module that I have logged in to, but I dont see how that could affect PKCS#12 certs but I read in some guide that I had to do that. Which also apparently mean that master password is set for protecting credentials in the application, so I have to provide that password when opening Tunderbird.

I got an email supposedly from breach-alerts@mozilla.com that claims there are currently 3 data breaches and has this link to resolve: https://blrv1ly5.r.us-west-2.awstrack.me/L0/https:%2F%2Fmonitor.mozilla.org%2Fuser%2Fdashboard%2Faction-needed%3Futm_source=monitor-product%26utm_medium=product-email%26utm_campaign=monthly-report-free-us-scan-no-exp-yes-breach-resolved-no%26utm_content=resolve-exposures-us/1/01010195ceba1024-6e3f74fe-119a-4e2e-9033-398671a830d9-000000/DDeGOTLjROOXCCk2fJvXJbdefc4=419

This seems like a phishing email, is it legit? Should I find another browser?

Recently transferred from Chrome. My understanding was Firefox private browsing was supposed to work similarly to chrome incognito mode; once you close the browser, all local files are deleted and cookies are cleared.

However, with Firefox it maintains my logins. If I log into an account while private browsing and the close the browser, I’ll still be logged in next time I go to the website even if it’s days later (and I have never logged into this account in a non-private browsing window!)

I never had this issue using chrome incognito, so it seems to be a Firefox problem.

Is this just not something Firefox supports? Is there any way to prevent storage of cookies and private data?

I couldn't send email, so I deleted and re-setup my email account. This lost my remembered passwords, so now I can neither receive or send email. My basic password still lets me onto TB though.

Setting up a desktop (Dell Inspiron) for neighbors using latest Linux Mint (21.3 Cinnamon). They have simple needs, LibreOffice, Firefox and email. Plain jane, nothing extra added, straight from latest Mint install.

I am having trouble adding a second email account in Thunderbird (115.8.1). First comcast account was very easy, standard comcast defaults, works fine, downloads and sends. Second comcast account keeps giving "Unable to Connect" poput screen. (https://localhost/?code=0.ac.w2.PciwTw)

I can login to either Xfinity email account through Firefox browser using same addresses ((username)@comcast.net) and passwords I am using to attempt to add second account in Thunderbird.

Tried it with Mint Firewall off, then on, then off again. Do I need to setup firewall for second account?

Can someone give me a hint on this problem? Is is Thunderbird? Comcast? Something else?

Guten Tag,

ich benötige Hilfe das Googlefenster weg zu bekommen. Ich möchte mich nicht über Google anmelden, wenn ich es auch über Mozilla kann. Die Anmeldedaten von Mozilla funktionieren nicht.

Bitte sagen Sie mir, wie ich das Problem lösen kann.

In dem Fenster habe ich keine Möglichkeiten die Links an zu klicken, da dann das Fenster weiß wird. Ich kann es nur wegklicken, es kommt aber innerhalb von 5 Minuten wieder. Oder ich melde mich mit google an, was ich aber nicht möchte.

Danke für Ihre Hilfe.

I had to change my gmail pwd due to a possible security breach as reported to me by Experian.

After the change, Tbird flashed this error message upon the next startup (please see image)

After about 20 minutes of poking about, I found where I could change the password for my google account. I changed it to the new password. There is zero chance I got it wrong because I copy/pasted it from my pwd mgr. I still get this error message making T'bird useless to me.

I'm definitely let down that such as simple op as pwd change was so difficult to find and now seems impossible to do. I haven't a CLUE what the STAT command is or how to address this condition.

Any suggestions are greatly welcomed.

I have just completely reinstalled Thunderbird v115.11.1 after uninstalling the previous installation. There are two problems, possibly linked to a faulty or missing setting.

Remote images will not display, even after specifically enabling remote images for each email, or after turning on "display remote content" as a default. Also it claims there is a potential security threat with Thunderbird's own web addresses: "live.thunderbird.net." and "addons.thunderbird.net.".

I have attached screen-shots of the error messages, and of a thunderbird email that fails to display its images.

After upgrading to Thunderbird 60.2.1, I can no longer send messages. I'm running Linux 4.15.0-38-generic.

I get the attached error saying that I have problems with STARTTLS SMP. However, I have my connection security as SSL/TLS (second attachment). I haven't changed anything for years on my connection security. I successfully sent emails yesterday. Sending still works on my other machine (Windows) with v 59 and the same settings..

Hello,

I am setting up PGP in Thunderbird. Sometimes I want to send an email which is signed but not encrypted. However, before I send this to someone else I want to make sure that it works. So I sent an email to myself (2 different accounts which I both control and have added to Thunderbird). The email has the signature attached but the Thunderbird UX doesn't give me any information about whether or not it successfully verified the signature. I tried downloading the `.eml` file and checking the signature against that, but it failed (I'm assuming that I tried to verify the wrong thing, not that the signature is actually bad).

Any help would be appreciated.

Firefox 125.0.1 update breaks all self signed certificates

After the latest auto update I can no longer access any of my management screens on my private network with self signed certificates. This is a real problem. I have attached a couple error screen grabs, but ALL of themn are the same. The information link says there is no workaround!

So how do I recover access? Chrome works just fine ... so it is def. a Firefox problem.

I have unsubscribed from all newsletter after receiving the first email but days later I'm still getting emails from Firefox (e.g. Superpower #4: See if your info has been leaked).

This is an incredibly bad user experience and to my knowledge illegal in the EU.

I'm probably still within that journey but the journey should terminate the moment I clicked unsubscribed.

Having tried all pointers to how to display this data, I give up and present my case here: In a banking app, the login field is blank and requires me to enter the correct Login ID. This works fine. However, if I double click on that field, an option is displayed, happening to be my email address, which will not work in this case; a numeric value is required.

So, knowing a prompt is enabled, I have entirely failed to get 'it' to save the correct ID. I have also find a place in Firefox settings where I can see and modify the value that comes up. I do however remember doing exactly that for some other site.

So, as I have said, I cannot find this in the Passwords nor the Settings pages. What am I missing?

Help would be much appreciated.
