Hi Firefox Team, I've been a Firefox browser user for the last 5 years and now I'm facing difficulties while loading webpages, Is there any solution to loading the webpages so I can continuously use it...

For weeks now google translate has not been working as it should, when I translate something it usually defaults to translating it to English, but if I change the language to any other than English it still only shows the English translation (or whatever language it got "stuck" on).

I have signed out and in of my google account, have the latest version of Firefox (134.0.2), refreshing the pages doesn't help. I don't have this issue in other browsers.

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).

Downloads on Firefox are slow. They used to be fast, but about three days ago they just went way down to about a tenth of the previous speed. I've tested the same file from the same source and on Edge it downloads at the speed I used to get, so it's a problem with Firefox.

We are getting errors that css values not defined as if the css file is not loaded from our CDN, which is only happening in Firefox and not other browsers that we support.

We confirmed something changed in Firefox that is triggering this around FF version 132. With the ESR (currently 128.5) and the page is working correctly. When we switched back to latest 133 and the bug is there

In the situations it happens, sometimes our css is NOT being loaded. In others, it is loaded and doesn't work but I see things trying to render before the file shows up in the console network logs. When it works...it is coming up cached. So this feels like a race condition of some type

I'm pretty sure the rule is that css is blocking, because we discussed race conditions when we implemented this, so this might be a Firefox bug? If this is a Firefox bug that isn't in an esr yet, we want to get it filed against firefox and fixed before the next esr.

We even tried a hacky patch on our code's method that is in question, as well as tried putting the expected css font-family style into a <style> tag in our index.html. The patch worked on Windows. It did not work on Mac. Stepping through the code, we see `undefined` / `null`. This definitely implies that the css styles simply have not been applied when the first component asking for the theme is routing through this code.

So again: our Firefox > 132. ESR up to 131 doesn't produce this issue, so something changed in Firefox 132.

If we tried loading our css file in a parent page (just loading, not using) to get it into the mix sooner, it doesn't help. An iframe is still loading faster than its parent frame is loading that css file from the CDN.

On Mac but not on Safari Firefox buffers for minutes before connecting. I’ve tried clearing the cache with no improvement. Until recently I never had this problem and as I said there’s no problem on Safari.

I can use edge and my speed tests perfect on speed test. If I use Firefox the upstream is half. I only have block installed but doesn't matter if I disable or not.

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.

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’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.

Since the last update on both my desktop and laptop web performance has slowed considerably. Some sites time out, some just don't connect. I've tried VPN on and off, changed security levels, deleted extensions to no avail. I use Windows 10. Is this the future with FF? Time, after many years using FF synced across all my devices, to bail?

Please advise soonest as this is more than frustrating and unproductive. Thanks Stephen

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.

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?

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.

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?
