Apparently downloads of the Firefox browser are tagged with something called dltoken so Mozilla can count unique installations. How do I verify the authenticity of the download since they don't match the untokened hash checksum?

I know downloads off the ftp site won't have the token, but I installed first and then remembered to check later.

why is it a web site accessed couple days ago, now times out trying to re-access it another day?

i called the web place in question and their system is up.

thank you

I am experiencing an issue where Google.com (other google domains work fine) will not load in Firefox, resulting in an infinite loading loop. Other browsers on the same system (Brave) work fine.

Here are the steps I have already tried:

Reinstalled Firefox completely

Removed Firefox via sudo apt remove --purge firefox -y

Cleared all user profiles and caches: ~/.mozilla/firefox, ~/.cache/mozilla, ~/.config/Mozilla

Reinstalled via Flatpak

Tested network connectivity outside Firefox

curl google.com works correctly

DNS resolution works via getent hosts google.com in the host system

Checked proxy settings

Ensured “No proxy” is selected in Firefox → did not resolve the issue

Tested in Safe Mode (disabling extensions)

Problem persists, so not caused by extensions

Tried disabling IPv6 inside Firefox

network.dns.disableIPv6 set to true → no effect

Cleared DNS cache inside Firefox

about:networking#dns → clicked “Clear DNS Cache” → no effect

Disabled DNS-over-HTTPS (Secure DNS)

about:preferences#privacy → “Use secure DNS” → disabled → no effect

Disabled HTTP/3 (QUIC)

network.http.http3.enabled set to false → no effect

Verified Flatpak network permissions

flatpak info --show-permissions org.mozilla.firefox shows network access allowed

Inside the Flatpak shell:

flatpak run --command=sh org.mozilla.firefox getent hosts google.com

→ returns only IPv6 address: 2800:3f0:4001:839::200e google.com

Hello! I have a problem with GeForce NOW in Firefox. When I launch any game, the cursor freezes and does not move inside the streaming window. Outside the GeForce NOW window the cursor works normally.

Details: - Only happens in Firefox - Other browsers work fine - Cursor gets stuck right after entering a game - OS: Linux (Arch)

Is there any fix for this? Maybe it's related to pointer lock or hardware acceleration settings?

When I opened Firefox[^1] today I was greeted with a "Donate to Mozilla Foundation" page open, with the message:

"You power Firefox. Now donate to make good tech the default.

Mozilla Foundation — the non-profit behind Firefox — is building a future where technology serves people, not power.

Your donation to Mozilla Foundation keeps the internet open, private, and built for people. Donate today to make good on the promise of the internet."

Does this message mean that Donations to the Mozilla Foundation now fund Firefox development? As I understand it, previously donations were not allowed to be used by the Mozilla Corporation, which actually develops Firefox. I'd love to donate to fund Firefox development, as I feel it is a critically important open source project.

[^1]: 145.0.2 from the Mozilla Debian repository.

I recently tried to connect to two different meeting sites. Both times I got a pop-up noting (correctly) that camera and microphone are blocked. I'm able to click to enable the microphone but I never get the option to enable the camera.

I tried going to Settings>Security&Privacy>Camera but that only allows me to remove previously-enabled websites.

Clicking on the settings button in the address bar shows audio and recording settings but no camera.

What am I doing wrong?

Fedora 42 Firefox 145.0

I'm on Ubuntu (LTS) FF 145.0.2

The audio plays fine, but the video (youtube) freezes like every 40s or so. Playing videos in MPV or Brave is flawless. I dont see extra ordinary CPU activity or anything obvious.

Ideas why this could be?

Is it possible to make a donation to Mozilla without providing so much personal information? I got a message on Firefox today asking for a donation, but when I tried to do that, I was asked for my home address. It's a general rule of internet marketing that people who use the internet would rather do anything than pay for something, so it's bad psychology to impose unnecessary conditions when you're asking for a donation. I don't have to provide my home address when I make donations to other organisations, so why does Mozilla need my home address? I apologize if this is the wrong place to ask this question, but I can't find anywhere else to ask it!

Thanks,

Shaun.

Bonjour, Sur mon P.C, il est impossible d'avoir ma position, votre logiciel me situe à Laval, alors que j'habite Saint-Etienne, du coup, il m'est impossible de regarder aucun site marchand style brico-dépôt ou autre puisqu'il me situe au mauvais endroit. Auriez-vous une solution à me proposer, d'avance merci.

Hello. I'm having trouble with bookmark icons in my browser. Sometimes the icons show up, but sometimes only the globe appears. I've tried everything, including installing the "Bookmark Icon Loader" and "Bookmark Tab Icon Changer" add-ons, but it didn't help. Is there a way I can change them manually in the browser itself without any add-ons?

Hi,

On some websites (e.g. archlinux.org) most numbers are not rendered. See attached screenshots showing the same page on Firefox and on Konqueror.

In my font settings, I do allow pages to change fonts. Some pages (e.g. this one) do change the fonts and appear well. However, if I disable the feature, then they also break.

I'm using: firefox 145.0.2 (64-bit) archlinux plasma-desktop 6.5.3 wayland 1.24.0

Any idea?

FF 145.0.2 (64 bit) canonical-002 - 1.0 running on Kubuntu 25.10 has suddenly started locking up completely after a minute or so with an "unresponsive". As I have just put in the crash reporter: "I haven't had problems with FF before but just possible that this relates to my growing problems with Thunderbird see https://support.mozilla.org/en-US/questions/1551791. I putting a question in Mozill Support about trying to keep my tabs and perhaps groups before doing a complete reinstall." So my questions here are:

• I am planning to to a complete clean reinstallation from snap but is there a better (more stable) installation?
• either snap specific or generically: is there a way I can find the open tab list from the debris of this snap installation (and perhaps the groups but that's less important)?

TIA,

Chris
