Firefox Community Forum

Siriusxm won't display fully on my Firefox, the selection buttons don't show. It works fine on Chrome - Sirius says it's about Firefox. file:///C:/Users/Owner/Downloads/Screenshot%202025-08-27%20at%2013-38-08%20SiriusXM%20Streaming%20Music%20Sports%20News%20Podcasts%20&%20Talk.png

I'm not sure whether i am in the correct forum. I have successfully copied to a USB stick the bookmarks from my old PC but, although I can open the html file and see them, I cannot see how to present them in the bookmarks menu. I am not recognising a simple "import" option such as I found with passwords. What am I missing

I have tried many times to change my location that is displayed and it will not change. I do NOT live in the State displayed. Whey will it not change when I enter a different city, state or zip code? Constance Mahan Saint Charles, Missouri 63303

I've gone through the various troubleshooting options over the last month or so and Firefox is still crashing constantly for me, even in Troubleshooting mode. The tabs crash when I'm using a Google Doc, YouTube, Discord, doesn't matter the site; I've submitted about 20 crash reports this morning alone and failed to submit several more:

Any help on this would be greatly appreciated!

running version 142.0.1 on windows 10 on a pc. With the latest three updates of firefox, facebook is the only site that loads very slowly. No problem on a pad or cell phone using the same isp and mozilla. What happened?.

I’ve been using Firefox with a screen reader, and while it works for most basic browsing, I’ve noticed some issues with certain sites. For example, form fields aren’t always announced properly, and sometimes navigation landmarks are skipped. When I test the same pages in Chrome, the experience feels smoother.

I’d like to keep using Firefox, so I’m wondering — is there something I can adjust in my settings to improve screen reader support? Or is this more of a compatibility issue that needs to be reported as a bug?

If others here use screen readers with Firefox, I’d love to know what has worked for you. Are there specific add-ons, preferences, or troubleshooting steps that make accessibility better?

Thanks in advance for any guidance.

It works in Chromium 139 , Firefox ESR 128 , and latest WPS Office. HOW IF A CHINESE USER CANNOT TYPE CHINESE IN LATEST NIGHTLY (Debian forky/sid ,Linux kernel 6.16-rc7-amd64)

I have started to delay Firefox updates as much as possible. Takes hours to get things back to normal, i.e. it appears to be done and installed, but access to say Google just clocks and clocks and clocks. Hence, I've avoided updates as much as possible.

I have already unchecked the smooth scrolling setting. i have also tried with and without auto scrolling. This problem is only on firefox on my laptop. My desktop PC firefox does not have this problem, and no other program on my laptop is doing this. when i scroll with my mouse wheel, the page keeps moving for like a whole second after i stop turning the scroll wheel, like lingering movement. I Hate It and it didnt use to do this. I want the pages to stop moving way sooner and stop sliding around!!! My problem that toggling the 'use smooth scrolling' setting does literally nothing and its driving me crazy. wtf is this and how can i fix it

Hi everyone,

I’ve run into a weird issue with my website, https://goldenretrieverguides.com/ . Some of the images don’t load properly in Firefox, but they display just fine in Chrome and Edge. I've checked caching, image formats (mostly JPG and PNG), and even tried clearing the browser cache.

I’m using WordPress with an image optimization plugin, and the site is SSL-enabled. Could this be a security or compatibility issue specific to Firefox? Any suggestions on what I should look into or debug?

Thanks in advance!

Since updating to Firefox 141.0 (Win11), I've had issues with performance and on-screen behaviour of dynamic web pages/sites. The problems do not manifest on Chrome, or on a reinstalled version of Fx 140.0.4 on the same computer running at the same time (and with copy of original profile's data files, extensions etc.), they do manifest on a new Firefox 141.0 profile with only one tab open.

The problem happens on dynamic pages (e.g. gmail.com, boardgamearena.com/lobby) but doesn't seem to happen on static pages. Note that this doesn't depend on page elements moving around the visible window (e.g. panels opening and closing).

The manifesting problems:

• Screen pointer rapidly switching between standard arrow pointer, mouse with index finger (clickable link) and serifed-style insertion bar, even when positioned on a part of the page that is not a link or a text box. Video (MP4, <1MB) showing behaviour at https://imgur.com/a/absjTh4.
• Browser intermittently fails to respond to browser actions (mouse clicks, keyboard entry)
• Small increase in browser CPU usage

Problem is worse if general CPU usage (from other applications) is already high - low CPU usage reduces but doesn't eliminate the problem. (Established by changing my BOINC settings and/or snoozing BOINC and observing; I have a gadget that monitors CPU and other resource usage.)

The fact that I can see the problem occurring on Fx 141 but have Fx 140.0.4 working fine at the same time on the same page, suggests that this is a Fx 141 issue. Regular malware scanner and an alternate found no issues.

Happy to do more diagnostic testing if it's helpful.

Firefox Support Team, Hello I am a Firefox user in mainland China. I'm experiencing slow webpage opening (all webpages) with Firefox, and the problem persists after disabling the doh setting on Firefox as described on Firefox support. So I tried to change the doh settings on the OS (my OS is Windows 11, which supports doh settings on the OS), when I tried to use only the doh provider (Alidns) in mainland China, Firefox could open web pages very fast, but after I added the doh provider Opendns) outside of mainland China. Firefox becomes very slow in loading web pages. This problem only occurs in Firefox, not in chrome or edge (I currently use both Alidns and Opendns, Alidns as first choice and Opendns as backup).

So I would like to ask if Firefox has a logic that determines the priority of dns usage, prioritizing one of the dns providers when there are more than one at the same time. If so, can I change this logic. Because using dns services from other regions in mainland China will encounter problems such as very high network latency, packet loss, etc., I set up different regional dns providers at the same time as a backup, and I mainly use the mainland China dns provider.

My temporary solution for now is to actively enable doh service on Firefox and customize Alidns as the service provider. This gets Firefox working, but I think it adds complexity. Best regards, someone

The above is machine translation, the original Chinese text is as follows: 火狐支持团队，你好 我是中国大陆的火狐浏览器用户。我在使用火狐浏览器时遇到了网页打开缓慢的问题（所有网页），根据火狐支持上的描述关闭火狐上的doh设置后问题依旧。于是我尝试更改了操作系统上的doh设置（我的操作系统是Windows11，支持在操作系统上设置doh），当我尝试仅使用中国大陆的doh提供商（alidns）时，火狐可以很快的打开网页，但我加入中国大陆之外的doh提供商（opendns）后。火狐加载网页就会变得非常慢。这个问题仅在火狐浏览器出现，在chrome和edge上不会出现（我当前同时使用alidns和opendns，alidns作为首选，opendns作为备用）。

所以我想询问火狐浏览器是否有判断dns使用优先级的逻辑，在同时有多个dns提供商时优先使用其中某一个。如果有，我能否更改这个逻辑。因为在中国大陆使用其他地区的dns服务会遇到网络延迟很高、丢包等问题，我同时设置不同地区的dns提供商是为了备用，主要使用的是中国大陆的dns提供商。

目前我的临时解决办法是主动开启火狐上的doh服务，并自定义alidns为服务提供商。这样能使火狐正常工作，但我认为这样增加了复杂性。 谨致问候, someone

Description: We have encountered a significant performance issue with NativeMessaging API in Firefox when an extension communicates with a native application.

In scenarios where many objects must be enumerated (e.g., ~458 certificates), Firefox is dozens of times slower than Chromium-based browsers.

Environment:

Firefox (latest stable, reproduced in 2025)

Windows 11 x64

Same machine and same native plugin tested in Chrome, Edge, Yandex Browser

Steps to Reproduce:

Create a WebExtension that communicates with a native application via NativeMessaging.

Perform enumeration of a large number of objects (≈ 450–500).

Measure execution time in Firefox vs Chromium.

Actual results:

Firefox: enumeration of 458 objects takes ~2 min 30 sec

Chromium/Edge/Yandex Browser: enumeration of the same 458 objects takes ~5 sec

Additional tests: Round-trip time (RTT) for a single message:

Firefox: ~73.7 ms

Chromium: ~0.3 ms

Because the extension and the plugin exchange a large number of messages, this performance gap becomes critical.

Expected results: NativeMessaging API in Firefox should perform at a level comparable to Chromium browsers, so that extensions relying on heavy message exchange remain usable.

References: Bug 1288912 – Native messaging performance is extremely poor

Although this bug is marked as resolved, performance testing still shows a major discrepancy in the current versions of Firefox.

Question: Is there any ongoing work or plan to optimize the implementation of NativeMessaging API in Firefox to address this performance issue?
