Within the last week of time, all of a sudden, my ability to access Grok.com seems to be failing. Most of the time it seems to get stuck on "Transferring Data: CDN.GROK.COM". Grok attempted to assist in this matter, we have set a new blank profile for Mozilla, we have tried setting network.http.http3.enabled to false, we have tried relaxing the tracking protection for the website, but nothing seems to be helping. Grok feels that this may be due to a update done around the 18th of August.

There is a brief, black flash that occurs after I enter grok.com in the search bar (using Google search for the engine), and then it gets stuck at the above point. I am in a very intense project with Grok, and I absolutely hate Chrome browser, but Grok works fine in Chrome browser, and my mobile. I am running this on a Razer 14", with AMD Ryzen 9, Windows 11 (full legal version), and Microsoft products. Plenty of HD space, and once again, it DOES work with Chrome.

hello, I've been having a recent issue/bug whenever I get a menu pop up from firefox I cannot select any of the options. happens across multiple website on both the mobile and desktop view options in the app. thought the update might fix it by no luck. I'm on a xiaomi Thank you very much everyone! picture for reference

I'm on 153.0.4 (64-bit) and after the last update, drop-down arrows are non-functional. I use Firefox at work and the dashboards that I've been using can't be used because I can't make selections. I'm having to use Microsoft Edge (yuk).

Is there something I can do to restore the drop-down behavior?

Thanks, JR

Firefox has stopped displaying the COX home page at https://www.cox.com/residential/home.html?campcode=redir-myc-hom . I can see the back pages if I connect to them from a link, but the home pages does not display. All I get is a error that says, "Oops something is wrong. Please try again later. And a circle that just "buffers" constantly. If I connect though a book mark to the payment page or one of the other pages I can see it. The error used to start for a minute when I turned my computer on and correct itself but now it is permanent.

Cox is telling me that it is a Firefox issue and I should get "another browser". But there is nothing better then Firefox. Everyone else works, even Google and Yahoo, just not COX.

Thanks.

Hi, I can no longer login using Firefox (latest version for my mac 154.0) into a website that I had no issues logging into until now. Nothing that I am aware off changed on my computer during the last few months. I turned off protections for the website, but it doesn't help. It just sits there, no error message.

I can login into the same website, with the same exact credentials using Safari.

Any idea why this might happen? Does anyone else experiences the same?

For the last five days I've been unable to login to a particular site unless I clear the cache EVERY time I want to login. It's a site I've been using for many years but now I just get a message saying 'An error has occurred. Please try again later.' When I try later, the error still exists. I don't get this error message when using an alternative browser, but I don't want to do that. It's also the only site I'm having issues with ....................... which is strange. The site in question says that I'm the only one facing this problem. Any thoughts?

I am on the VistaPrint website and have an Ai support window open that I can't close because the entire window is not visible. I need the top of the window available to close it out and unfortunately the window blocks me from doing anything. I have backed out, logged back in and the window is still present. I contacted Vistaprint and they said it was a firefox issue and to try Chrome. I used Chrome and they are correct, I can access everything, went back to firefox and tried but the window is still present, if the window size could be reduced, I could access the top to close it. Please help.

Facebook emojis are not showing but the ability to select them remains. When you want to select an emoji on a post you move the mouse over the thumbs up icon. In the last couple days all I get is a black window. But I can still move the mouse over that window and see in text what I want to select.

I am running version 154.00

I have turned on safe mode and the emojis work normally. They all show up.

I have gone through all my add on's and none of them actually effect the outcome.

Picture attached to show the black window.

I use WhatsApp web with Firefox 151.0.3 on a Macbook Air. In WhatsApp web, you should be able to emoji over a message sent by someone else. One clicks on the smile icon at the side of the message, the emoji pallet appear above and select one of a handful of emojis. Since a recent update, the pallet no longer opens. It's just white space, the cursor does not change allowing you to pick one of the emojis. See screenshot. Is there a fix for this please?

This is a bit difficult to explain, but I'll do my best.

Our company uses NetIQ Identity Manager, which we access through a web browser. I primarily used Firefox until I had to switch to another browser because of this issue. The problem only occurs in Firefox; I have tested several Chromium-based browsers, and none of them exhibit the same behavior.

On a specific page within the application, there are two panels: one displays a list of users, and the other displays details for the selected user.

The issue is that Firefox does not show a separate scrollbar for the user details panel. Instead, it only scrolls the page based on the height of the user list panel. As a result, when the user list contains fewer entries than the amount of information displayed in the user details panel, Firefox is unable to scroll through the entire details section. The hidden information still exists and becomes visible if the browser window is resized to be taller.

When the user list contains enough entries to make that panel taller than the user details panel, all user details are displayed correctly and scrolling works as expected because the entire page can be scrolled.

In Edge and other Chromium-based browsers, both panels have their own scrollbars. The scrollbar for the user details panel is only displayed when necessary, such as when the amount of user information exceeds the available space, but scrolling works correctly in all cases.

Is there anything that can be done to resolve this issue?

Unfortunately, the page is hosted on our company's internal network, so I am unable to share it.

The issue first appeared at the end of February this year. I believe I was using Firefox version 148 at the time. Prior to that, the problem did not occur. I am using Windows 11 and have tried the troubleshoot mode, which did not help.

I just purchased a Keychron Q1 MAX keyboard. To customize the keyboard you need to use the online Keyboard Launcher (https://launcher.keychron.com/). That website says that only Chrome, Edge & Opera are supported if you're using Firefox.

Hello Mozilla Support Community,

We are troubleshooting a cross-origin resource sharing (CORS) issue specifically occurring in recent Firefox releases when processing custom B2B appointment requests.

Setup & Context:

Our production application, Frontline Sales Consultancy (flsc.co.uk), triggers a client-side fetch request to an external CRM gateway.

The request works seamlessly on Chrome and Edge, but Firefox throws an NS_ERROR_DOM_BAD_URI during the OPTIONS preflight check.

Observed Behavior:

Firefox Web Developer Console shows the preflight request failing before headers are evaluated.

Access-Control-Allow-Origin and Access-Control-Allow-Methods are explicitly declared on our origin server.

Does Firefox handle strict MIME-type checking or preflight caching differently for custom HTTPS API endpoints?

Any insights into Firefox-specific CORS strictness or network console debugging flags would be greatly appreciated.

Thanks!

I am experiencing a severe issue on the LINE Official Account web app (https://chat.line.biz) using Firefox.

Problem Details: 1. Every time I switch between customer chats or type a reply, the chat window automatically jumps/scrolls up to old messages (sometimes minutes prior) instead of staying at the latest message. 2. It happens consistently across almost all chat threads, forcing me to manually scroll down every single time.

Troubleshooting already attempted: - Cleared all Cache, Cookies, Local Storage, and Session Storage. - Tested in Troubleshoot Mode (all extensions disabled). - Toggled layout.css.scroll-anchoring and general.smoothScroll in about:config. - Issue does NOT occur on Chromium-based browsers (Chrome/Edge).

This seems to be a compatibility issue between Firefox's DOM re-rendering/scroll anchoring mechanism and LINE OA's React web app code. Please help investigate.

when Google share links are sent to me, they won't open in Firefox. I have to copy and paste the entire uRL and open Chrome in order to view them on my android device. Pixel 9

1. continually played by frame and zoom issues despite adjusting accessibility settings.

2. YouTube comments cannot be edit.

3. before I could remove individual data history and other individual settings from sites but now I cannot select it. I understand my script extension has something like this but I thought that the browser before had more flexibility.
