Firefox Community Forum

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?

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.

Recently I had to install a new windows, and I signed in to my Firefox account and found all the data from the previous windows including the open tabs, I could find them from "Tabs from other devices".

But now can't find them any more, although that device name is still there in my account page, under " connected services", please advise.

On two different Windows machines, current Firefox (153.0.1), the alt-d shortcut stops working: it does nothing until I restart Firefox. Then it works again for a while. I've tried about:keyboard and it's not reset there. I tried all combinations: Clear, Reset, setting it to alt-d explicitly. None of those worked. But when I set it to alt-a, that worked--but then resetting back to alt-d again didn't work. That shortcut is muscle memory at this point, so it's quite distressing. Not sure what diagnostics might be available to help here, happy to try anything.

Full disclosure: Both machines are Windows 10 but since that's stable, I find it hard to believe that's related.

my tabs bar, containing several hundred tabs, in firefox has suddenly decided to disappear and i can't get it to show. same for the menu toolbar (the one w/ the open, save,...) never really know which toolbar i am looking for. using latest version of ff and windows 11 desktop tried to get info directly from mozilla, but is the only place that probably has the answer.

what ever happened to support for the browser? it was relatively easy to get to the support area but now it mostly shows self-advertising for firefox.

thanks in advance for any help on this matter!

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.

linux, firefox, and duck duck go search engine---i want to stop picture in a picture. include every instruction like if i am to use the address bar, where do i find that?

I've received notifications from Mozilla stating my Mozilla account was used to sign in. Info posted in email states it was Firefox on Windows 10. My city and state accurate. Day, date, and time is ok. I've been using windows 11 for some time now. How can i trust Mozilla, if they can not detect the right windows version?

Thanks. George K

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!

Suddenly, I am getting unwanted ads every time I do a search or open another window on Firefox. It is extremely annoying and I have tried everything. This annoying practice includes even opening opinions/articles in the wsj. This, I believe, is outside what a browser should be providing. Popups that are unwanted and are part of the operating system is just not right. I am considering going to another browser as my default because of this intrusion.

I am getting constant pop up "alerts" on the right side of my screen that block my view. When I close one another pops up. It's very annoying. All of them have

the Firefox logo and name in the upper left corner.

Thanks.
