I have been using Firefox for a number of years. I use it with Windows 10. My internet connectivity has recently degraded to the point it is no longer viable. It is painfully slow and I keep getting "time out' notifications. I contacted my service provider and they suggested using a different browser. Although I was skeptical, I installed Chrome on my machine and tried it. Connectivity is back to normal. Why? What happened to Firefox? It shows as being up to date. How can I fix it?

my laptop wont let me play Roblox on it it says i need to download the app i click that so it does downloads but it say an error on it and it is not the internet connection. please help i want to play so please write back.

Once I visit any web site that uses HTTPS there is approximately a 90% chance it'll take seconds or even minutes to secure the connection. This never happens on other browsers as they load such pages instantaneously.

I already cleaned my data up and removed the extensions, both suspected and innocent bystanders, to no avail.

As stated in the title, I'm using Firefox 139.0.1 x64 on Windows 11 (24H2, build 26100.4061). This started happening after an automatic Firefox update, I never changed anything in my system configuration.

Working on setting up a new PC build. I've had to use some PC support website chats and many of them have just not acted right? For example, one would allow me to start a chat but then sent me directly to closing the chat like we were finished. The others would lock up my Firefox many times. Anything come to mind as to why this is happening? Windows 11 Pro v24H2 and latest Firefox version.

My browser has been acting off lately, it takes a longer amount of time than usual to even open gmail. Sometimes, it just fails to connect to a server and keeps loading forever and just stops (including gmail).

I got a Firefox update recently and have not been able to access Flickr since then. I am getting a message that the page is not redirecting correctly. I am attaching the error message. I am running with standard firefox protection. I have cleared cache and cookies. I have also added Flickr as an exception to Firefox enhanced privacy tracking. Firefox is up to date (version 134.0.1 (64 bit)). Anyone else having this issue or know the solution?

If I visit the website www.silviadesimone.it (I am the webmaster) through Google Chrome or Microsoft Edge, I can see the visit counter in the left bottom corner of the page. If I use Mozilla Firefox (that is the browser that I normally use) the visit counter does not appear. According to the ShinyStat helpdesk it could depend on some Firefox plugin that does not allow the counter to show. Can you help me? Thank you

I’ve been troubleshooting a strange networking issue in Firefox that I haven’t been able to pin down, and it seems to be specific to Firefox’s network stack rather than my system or connection.

On several high-traffic sites that sit behind Cloudflare (Discord, Shopify storefronts, some SaaS dashboards), Firefox occasionally stalls during page load. The request shows up in the Network panel as pending for several seconds before finally completing. Sometimes the page partially renders and then hangs until the stalled requests finish.

A few things that make this confusing:

• The same sites load instantly in Chromium-based browsers on the same machine and network • The issue persists even in Firefox Troubleshoot Mode with extensions disabled • DNS over HTTPS on/off does not appear to change behavior • Packet captures show the TCP connection is established quickly, but some HTTP/2 streams appear to wait before data begins flowing • If I force HTTP/1.1 using a proxy for testing, the issue disappears

System details:

OS: Windows 11 Firefox: latest stable release Connection: fiber, low latency, no packet loss locally No system proxy configured

Things I’ve already tried:

• Clearing cache and site data • New Firefox profile • Disabling hardware acceleration • Testing with network.http.http2.enabled toggled • Comparing HAR logs with Chromium

One thing I noticed in the Firefox networking logs is that multiplexed streams sometimes wait behind earlier streams longer than expected, almost like there’s some internal prioritization or queue behavior happening. I’m wondering whether this could be related to HTTP/2 prioritization logic, connection coalescing, or how Firefox handles Cloudflare edge endpoints.

Has anyone seen similar behavior or knows whether there are any advanced networking prefs in about:config worth experimenting with (connection limits, HTTP/2 concurrency, etc.)?

Curious if this might be a known quirk with certain CDNs or just something unique to my environment.

С ноября 2024 г наблюдается проблема : не загружается игра рыцари и принцессы. Несколько месяцев мне говорили что разбираются а сегодня написали что проблем нет из службы поддержки игры и отправили решать проблему с браузером в службу поддержки браузера mozilla ссылаясь на то что он не корректно работает и у меня старая ос. Страница загрузки https://vk.com/app4019000_26034467 .Мои попытки объяснить что проблема исключительно с их продуктом и у меня все программы игры и приложения работают ни к чему не приводят. Помогите решить проблему я уже не знаю что делать.

After a recent update to Firefox 133.0.3 (on Ubuntu GNU/Linux 22.04), Firefox is having difficulty connecting to websites and exhibiting some other odd behavior:

- After initially starting Firefox, it will load websites (e.g., previously open tabs) for up to 30 seconds. After that, it will not load any website in a new tab, showing the loading animation for several seconds before stopping all activity and just displaying an hourglass icon in the tab. These sites can be connected to in other web browsers. - After closing Firefox, its process is still running; I have to manually find its pid and kill it. - If I start Firefox from the terminal, I see these messages when it starts having trouble loading websites:

libva info: VA-API version 1.20.0 libva info: Trying to open /snap/firefox/5437/gnome-platform/usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so libva info: Found init function __vaDriverInit_1_20 libva info: va_openDriver() returns 0

We use Firefox to check our bank accounts. For that last 24 hours, we are stopped at a page that says Firefox cannot connect due to security problems. Does anybody know what's going on?

i AM RECEIVING EMAILS ALL DAY LONG FROM SECUREDJOINTNETWORK TELLING MY SYSTEM IS INFECTED.. MY SECURITY PREVENTS THAT i WANT THESE NOTICES STOPPED, BUT DON'T KNOW HOW TO DO IT.

Hello,

I am having major issues with Firefox speeds, Mainly upload speeds. On Edge I am getting 400 up & down (no issues at all). However, on Firefox upload speed is 144 Mbps, same on private windows. The only issue is with Firefox. Windows is up to date and Firefox version is 139.0.4 (64-bit)

Attached comparison screenshots for reference.

Below are the steps i performed:

=========================

Firefox Troubleshoot Mode Test: Download: 411.71 Mbps (Full Speed) Upload: 173.03 Mbps (Still Bottlenecked) Extensions Disabled Manually (Normal Firefox): No significant improvement. Hardware Acceleration Toggle (Normal Firefox): No significant improvement.

=========================

New Temporary Firefox Profile Test: Download: ~333 Mbps Upload: ~190 Mbps Problem persists even with a clean profile.

=========================

Temporarily Disable Windows Firewall Test: Resulted in ~349 Mbps Down / ~148 Mbps Up. Firewall re-enabled.

=========================

Could someone let me know how to get this fixed. Creating a new profile should have fixed issued assuming one of the extensions was causing the bottleneck. But even with a new profile its not making any difference.

I have an account with the site, https://www.thecalendarcreator.com . It is a software that creates calendars for the present and future years. I have turned off Enhanced Tracking for the site (that worked for another site of theirs that I joined). Some functions work, many do not work correctly, if at all.

My computer is a Mac, v 10.13.6, so it's getting old. I have contacted thecalendarcreator.com support, and they can't find anything wrong on their end. They have suggested that perhaps it's some sort of anti-virus setting on my end. I've been looking at my Settings, but I'm no techie, so I don't know what to do. I would greatly appreciate your help, so I can hopefully get this site to work.

Thank you very much, Lea Lashaway

Whenever I login to the web site "SSA.GOV" and click the login button, the next screen presented in Firefox is: "Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

If I go to a Private Window, type in the SSA.Gov and then select the Login page, I am presented with the correct page and can then supply my information and login.
