Diễn đàn hỗ trợ Firefox

when I try to sign in to face book I go through the sign in procedure and get stuck in a loop right back to the sign in page. I tried clearing my cash and cookies to no avail. Help!

Firefox recently seems to be crashing randomly when I disconnect from VPN. At least I think it's crashing. This has maybe started a few weeks ago?

What happens is that when I disconnect from my VPN (ProtonVPN), I will randomly not be able to load any pages. If I go to any website, it will just get stuck loading forever. No timeout. I'm able to visit the browsers own pages like settings, some about: pages like about:performance, about:memory, etc.

Why I'm not sure if it's crashing is because the browser itself is not closing, I have to manually close the browser window. Once I close the window manually and wait a while, the crash reporter pops up. If I close the window manually then re-open it, theres a text prompt that shows up telling me Firefox is still open and if I want to close it to re-open Firefox.

I don't think it's the VPN's issue as when I disconnect from my VPN, applications other than Firefox work and have internet connectivity (a separate browser like Chrome, or discord, etc)

What I have tried:

• new Firefox profile
• Using Firefox Nightly
• Various ProtonVPN settings (but I don't think its related to ProtonVPN)
• Various Firefox network settings
• Both Firefox and Firefox Nightly Open, when disconnecting VPN one would stop letting me reach sites but other wouldn't

I have the crash report details (from Firefox and Firefox Nightly) but unsure where best to upload or if it contains any sensitive data.

Maybe pasting this is fine? Both mention this at the last few lines of details: Winsock_LSP: Hyper-V RAW : 2 : 34 : 1 : 1 : 0x20026 : 0x8 : %SystemRoot%\system32\mswsock.dll :  : 1234191b-4bf7-4ca7-86e0-dfd7c32b5445

XPCOMSpinEventLoopStack: default: nsHttpConnectionMgr::Shutdown

And I also see this for maybe why the browser itself doesn't "crash" MozCrashReason: Shutdown hanging at step AppShutdownNetTeardown. Something is blocking the main-thread.

If it's okay to share the crash reports then I can add them.

I checked and borh of my Lenovo Chromebooks are running the 2026 version. Neither one will allow me to import bookkmarks . Is there a version I need other than the provided by Google?

I ran the commands listed in the instructions for installing Mozilla VPN with Linux and I got the following error after running the following command:

pub/{getline; gsub(/^ +| +$/,""); if($0 == "35BAA0B33E9EB396F59CA838C0BA5CE6DC6315A3") print "\nThe key fingerprint matches ("$0").\n"; else print "\nVerification failed: the fingerprint ("$0") does not match the expected one.\n"}'

I need to know what I need to do in order to continue on with the istallation

I submitted a bug last to Bugzilla last Sep. that seems not yet to be assigned to anyone, and a bug two days ago that wasn't acknowledged. Is the Bugzilla site working? Should I be doing something else to report the bug?

When I start VPN, it brings me to a page to choose a subscription, but I have a yearly subscription paid in November 2025. Then my Mozilla account says I am logged on but when I click on the application icon I get a circular icon in the window with a cancel button underneath it. See attachment.

I suspected I had hit a "translate" somehow, but with further inspection I think I may actually have been compromised. I'm using Firefox, but the problem follows me even if I switch to Chrome or smilar.

Can you help? Tks!

I got an email that my subscription for Mozilla VPN has been cancelled a month from now. I wonder why? On the "What’s New | Firefox 151" page the new free VPN service is announced. Does it have anything to do with that? Not yet in my region (Sweden) though. Kind regards, Monika Ivarsson

Hello Firefox Team,

I am writing to formally request the development and release of an official Firefox browser version optimized for OpenHarmony / HarmonyOS.

I am currently using a new smartphone running OpenHarmony 6.0. As the ecosystem grows rapidly, there is a substantial and increasing base of users who rely on this operating system for their daily stage environment. Currently, the browser options available on this platform are quite limited.

Firefox is widely celebrated for its privacy-focused features, strong extension/add-on ecosystem, and its independent Gecko rendering engine. Having Firefox natively available on OpenHarmony would significantly enhance the browsing experience, privacy security, and freedom of choice for millions of users within this new ecosystem.

Could the development team please consider adding OpenHarmony support to the official roadmap? Alternatively, if there is an existing experimental build, a community port, or a workaround to compile it for this architecture, I would greatly appreciate any guidance.

Thank you for your time, dedication to the open web, and consideration of this request!

Best regards

I am having problems with logging into the VPN app. I paid a one year renewal in November 2025 and have had access to the app for both logins that use this computer. It is an Apple M1 Macbook Air. On Wednesday, when I tried to connect, it sent me to a page to select a plan for payment.

https://www.mozilla.org/en-US/products/vpn/?utm_medium=vpn-client&utm_source=desktop-signup-flow&device_id=602c31e5c3e043c687df2d1e7fc17da1&flow_begin_time=1779492973967&flow_id=8baedf7abe0402e07ee2f21622b22c13e6f85621900a55935f3e1a2455c42d0c#pricing

Then when I tried to sign in again, it gave me the spinning circle shown in the attachment. It has now been a couple of days where I have not been able to use the app.

I do have access to the built-in VPN for one of my logins, but not for the other one. I have gotten replies from general support that told me to try the special support for VPN.
