Hi,

The scouting association have updated their members website to membership.scouts.org.uk. This works, but from there is a link to my learning.scouts.co.uk. Sometimes this works but often I get "bad request, error 400". I've had to move to Edge when using this website. I didn't want to! I've used Firefox for years

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.

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

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

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.

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.

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.

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 using the most current version of Firefox with Windows 10. At this web site: https://tenthousandpots.com/ , I am unable to browse the majority of the site i.e., no products appear when selected. I also tried DuckDuckGo and had the same issue. However, when I downloaded and accessed the site via Google Chrome, the site worked as it should. I reached out to the TenThousandPots site and advised them of this and they said they've had no similar reports. Can anyone advise?

So basically, I'm trying to add a 2FA code, homever when I scanned the code using google authenticator, everything went normal. Homever, when I try to put in the code, firefox only lets me put 5 digits but not 6. Any solutions?

I have noticed some minor changes in Google Maps. Unfortunately, they have affected the support of Maps in Firefox (135.0): maps are displayed without any names (towns, streets, objects, etc.). Since this bug is not present in the support of Maps in Edge, I think that Firefox requires a correction. When can we expect a fix?

Using Firefox on iMac, with Privacy Badger plugin. Can't log in to DocuSign. I believe it is a browser error, because I can log in using Safari. When I attempt to login to Docusign I get and application error, regardless of whether I use my password or a passkey (fingerprint id).

Related issue is when I click links to articles in emails from Flipboard (a content aggregator) I get a "Bad Request" error message. This just started happening. This also does not happen if I use Safari.
