As creator of retroonline.net. We recently noticed Firefox have limited value size in IDB which Chrome and Edge do not have. This limitation prevents big games running on Firefox despite Firefox has the best performance on WASM. Will there be a proper way to change this limitation or plan to remove it?

Every time I change the settings in the image attached, once I close the browser, the settings are reversed back. My changes do not persist if Firefox closes or my PC turns off. My other settings persist when I make changes. I only get this error when I try to edit the Privacy settings.

What is causing this, and how can I stop it?

Windows 11 Home Firefox up to date with 140.0.4 (64-bit)

Can messages on laptop be deleted . If I delete all messages from my desktop, will all messages also be deleted from stolen laptop if thief access thunderbird

I'm trying to send an OpenPGP-encrypted email from a Linux Mint machine using msmtp, relaying through the smtp server, to another Linux machine, to myself, running Thunderbird (with the sender's (my) imported private key already loaded and working in Thunderbird).

The encrypted test message is composed manually as a file (email.eml) and sent using msmtp from the command line. The email successfully passes through the SMTP relay, is received and decrypted by Thunderbird (so the OpenPGP decryption part works that much I know ... ), but the plain text content is not rendered properly and the email is displayed blank, no plain text as expected. Thunderbird has decrypted the message, but it’s not being displayed or rendered.

This makes me think the issue lies in the structure or MIME headers/parts of the .eml file itself — specifically how the encrypted message body is wrapped. This is not something I'm entirely familiar with, and even less so with what Thunderbird expects for a PGP encrypted message...

I suspect the issue is due to incorrect MIME formatting or missing headers (Content-Type, Content-Transfer-Encoding, Charset, or boundaries etc.) needed for Thunderbird to correctly render the decrypted body into plain text once it receives it. Since I’m assembling the .eml manually (and eventually by a script whej I get to it), I may be overlooking certain structural requirements that typical mail clients (say Thunderbird or similar) or gpg front-ends (like mutt, mailx ...) would handle automatically.

My questions are: Is there a correct MIME structure or format expected by Thunderbird for OpenPGP-encrypted emails ? Is this documented anywhere specifically for Thunderbird ? Or, are there publicly available examples or specs that describe how such an email should be structured (e.g., RFCs or working .eml templates)?

Is there a known way to validate or "lint" .eml files for OpenPGP compatibility ? That would be nice ;-)

As I said the internals or MIME formatting is not my thing usually. Any pointers to Th.B. documentation, sample files, or tools that help with .eml structure validation would be grately appreciated.

Thanks in advance, cheers MM

Hi all,

for signing PDFs with my SMIME certificate, another 3rd party software (LibreOffice) uses the Thunderbird profile folder (nssdb stored which is located there). After some investigation by myself, it could be a problem within Thunderbird certificate management itself.

Situation: I've a current and some outdated SMIME certificates for my mail address. But all for one mail address.

Because the current SMIME certificate is not accessible for LibreOffice, I removed temporary all of my outdated SMIME certificates from Thunderbird by the builtin certificate management, i.e. the list of my personal certificates was set to one entry (=the current certificate) in Thunderbird. But even then, LibreOffice lists only an outdated certificate (which is not visible anymore in the Thunderbird builtin certificate management).

Therefore I've checked with certutil the nssdb entries in the Thunderbird profile folder. Surprisingly, there is an outdated SMIME to my mail address contained (no further, even not the current one). Even after removal of those outdated certificates via the builtin certificate management. The current certificate is never listed; always only an outdated one.

This looks like a difference between builtin certificate management and nssdb within the profile folder (or may for another storage location of the certificates)?

certutil -L -d ~/.thunderbird/myprofilefolder --email mymailaddress

Thanks in advance!

When I log in to my account at https://my.noip.com/ and display my dashboard there is a constantly displayed banner across the top of the page that says:

FireFox prevented this page from automatically reloading - Allow

when I click Allow the page just reloads with the same banner

What setting can I change to get rid of this banner?

I am trying to set up an MMDVM Pi-Star DMR Hotspot for Amateur Radio. The address for the device is http://pi-star. What do I need to do to get https-only mode 100% disabled? The device that I am trying to set up is: Radioddity RHS-H1 MMDVM Hotspot | OLED Screen | Raspberry Pi-Zero W | Support P25/DMR/D-STAR/YSF/NXDN | UHF VHF WiFi Digital Voice Modem | 16G TF Card

I am using Firefox version 140.0.2 on PCLinucOS Debian (Bookworm) Edition.

Hello, I think I may have asked about this in the past but cannot recall if I received an answer. Under Settings, I get the message "Your browser is being managed by your organization." This is my home computer and is not being managed by any organization. When I click for more information, it gives me a screen with the following information:

Policy Name Certificates

Policy Value ImportEnterpriseRoots

                         true

If I could get more information on this suspected error, or how to correct it, that would be great. Thanks!

Some sites do not work correctly even if I select Custom and uncheck the boxes there, but these sites work in Google Chrome. One of the examples is the Twitch site. It's not displayed correctly in some places and there are probably other sites. I wouldn't want to add these sites manually, because personally I don't see any point in it for myself. I really hope that Mozilla has provided the ability to completely disable this function using standard tools (settings or about:config), without installing any extensions.

Thank you!

I have accounts that will not work because they cannot access my location, My computer says all access is allowed, so is there something in Firefox that blocks my location?

Why when I view a site in a private window are the cookies saved in the cookies and site data list on the privacy and security page of my main firefox pages. I though when you used private windows no cookies or history was saved once you closed the page.

Hello:

I'm not certain if this question comes under Firefox or not:

How do you stop a specific computer software program-app pop-up notification (popping out from the lower right corner of your computer)?

As an example, I have a utility program, IOBIT Malware System Care that pops-up various notifications such as "update notice," "renew," "discount sale" or whatever notice or ads that is 'pushed'.

-I went to my Windows 11 list of installed app "notifications" and this program is not listed. -I tried contacting tech support but they haven't responded. -I went to Firefox 'Settings' -> Privacy & Security->Permissions and then I opened up 'Exceptions' to see if I can block something. It wants me to put in a specific website. The issue is not a website but coming within a software / app program.

So how and where do I stop a "pushed' notification? I assume it's coming in via my browser / Firefox?

Thank you in advance,

Steven

I have all options enabled to save addresses and credit cards.

When I try to manually add a credit card, hitting the Save button does nothing.

When I use a credit card on a site, Firefox prompts me to save the card, I confirm that I want to save it, yet it isn't saved.
