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.

Cant post my question on reddit, so .. are they bunting firefox users out of sessions?. Ive been logged in then bunted out receiving "reddit is better with the app" message. Also bunted out on desktop, no mesaage. I only login using Firefox using synced passwords. These are correct. When blocked logging back in. Password is invalid. Request password reset email never arrives. Earlier in the week i verified my account email. I checked my logins and ip#s are ones ive used. Any ideas?

When I try to attach file via drag & drop, the Firefox always display "Download file" as attachment. I don't know why because it properly worked before. but after some updates, drag & drop is not working.

The version of Jira at my office is not changed for years(v8.12.1#812002-sha1:7c28d59) and drag & drop is working via Chrome, Edge and etc.

Good Day.

I have encountered a problem recently with on particular forum site.

When I attempt to login I receive an error after pressing the submit button. 

The form displays this error "The submitted form was invalid. Try submitting again."

I have been using the site regulary for several years and have never had this problem

The following is what I am using:

    Firefox ver 153.0.1 64 bit
    Windows 10 and/or Windows 10 (yes this is happening on all 3 of my PCs)

The forum site is using phpBB Forum Software. I do not know the version. As stated above they have been using this software for several years.

In trouble shooting this issue I have discovered that if I do the following in the specified order I can login and create and respond to posts and Private Messages. But as soon as I log out I receive the invalid form message until I do the following steps again.

            1) Clear all cookies, temporary cache, site settings, browsing and download history, site settings
               and saved form info.
            2) Shutdown Firefox 
            3) Navigate to my profile with Windows Explorer 
            4) Delete the file cookies.sqlite

I must do this each and every time I access the site.

I am at a loss as to what to do about this. Does Firefox have any error logs or console logs? If so how can I enable them to see if I can get a better idea of what is happening?

Thanks in advance for any help with this.

I can't download some pdfs, notably my bank statements. I CAN download some pdfs. Eg, I can download my car manual (although it's a process of downloading it to my Google Drive). However, trying to download my bank statements, Firefox gives me no options at all, and, indeed, I get an error message. Yet I CAN download my bank statements using Google Chrome! I've carefully checked all my Firefox settings, but nothing seems to address this problem. I've spoken to my bank, and they don't know why I can't download them either. When I try to download the statements, I get a screen saying it can't give me a 'Preview' (see attached screenshot), but there's a 'Download button. When I click that I get a white screen with the 'error' message:

"No API key found in request. request_id: d52e0732a3d10a75b1ec58534845c15c"

(2nd attached screenshot.)

I have asked about this before on this forum, but to no avail.

Unable to load https://fingtrainer.com as of yesterday. Been downloading the flingtrainer for single player games for a long time now and there is no issue. Try to disable/change enhanced tacking, dns, site were included in exceptions and reinstalling firefox does nothing. While the learn more link provide image solutions, none of them does anything and the disable button for the enhanced tracking is not working. Other browser like opera gx is able to load without any issue. Please assist with a solution or kindly revert the settings.

Server Not Found

Firefox can’t connect to the server at flingtrainer.com. Did you mean to go to www.flingtrainer.com? What can you do about it?

   Check to make sure you’ve typed the website address correctly and try again in a few moments.
   Check your network connection.
   Check that Firefox has permission to access the web (you might be connected but behind a firewall).

after the new version of firefox update my home page which i have always had Newsmax.com does not load says problem loading page i have tried several times and it will not load. it works in Google chrome so why not in Firefox

I sometimes sell items on sites such as eBay. When I try to copy and paste the picture (from my Photos) is just a weird symbol. If I go to a different computer it works! If I go to a different browser it works! When I open a weather App the radar is all washed out with different colors. What's the issue?

I have used Facebook in my Firefox browser for several years. Then all of a sudden, Facebook will load, then it will not load and yesterday and today, it won't load at all. I have to go over to Chrome to get on my Facebook. Please fix whatever is preventing me from using Facebook on Firefox.
