Firefox Community Forum

Hi, The site https://fortunenette.fr/ does not display properly in Firefox on my MacBook Pro running macOS 15.7.3 (build 24G419).

The header and navigation load fine, but the biography articles and the richest people table stay blank or show only placeholders. In the Firefox Console I see these errors: Uncaught TypeError reading 'length' of undefined, mixed content blocks for HTTP resources on an HTTPS page, and several CSP violations for inline scripts.

I already cleared cache and cookies, disabled all extensions, tried Private Browsing, turned off Enhanced Tracking Protection, and changed some about:config settings like strict transport security. Nothing helped.

The site loads perfectly in Safari and Chrome on the same Mac. It happens in Firefox 147.0 and the 148.0b2 beta too.

It seems like a Gecko-specific JavaScript or rendering problem. Has anyone else run into this? Any workaround without switching browsers?

Hi everyone,

I am facing a strange issue with my website's RSS feed when viewing it in the Firefox browser. While the feed seems to parse correctly in Chromium-based browsers, it looks quite unformatted in Firefox.

I’m worried this might be affecting how Firefox users subscribe to my updates. Could someone please check if there is a specific XML rendering issue or if I need to add a particular stylesheet for Firefox compatibility?

I’ve already cleared my cache and tested it on multiple devices, but the result is the same. Any advice or suggestions would be greatly appreciated!

Thanks in advance.

是最近才出现这种情况的，应该是某次更新之后出现，但是具体是哪个版本导致的我没有注意到。

问题描述：在任何文本框内输入文本，输入法候选框都会离文本框很远。假设文本框本身就靠下，那么候选框根本就看不见了。

在 Edge 浏览器中没有这个问题。

Youtube has two settings that must be turned on for captions to show and start automatically when watching a video. "Always Show Captions" and "Auto Play Captions" and not be forced to be signed in to YT. Both settings must be checked off/turned on for captions to work and "set" in the cookies, for captions to work when not signed into YT.

Previously, one could sign in to YT, re-select the settings, refresh browser and then sign out and the captions would work when signed out and viewing YT content.

Since your update today, YT's "auto play captions" option is now missing when using Firefox, but not when using chrome, meaning when using Firefox, it can't be selected while using that browser. The result is that persons who choose to use Firefox instead and don't want to be signed in to youtube, not wanting our information followed in a non anonymous manner, can't use firefox to watch YT and still have captions working without having to constantly turn them on for every single video watched (that's where "auto play captions" came in).

Bad, bad move. On both mozilla's part and YT's.

Within the last few days, I have been unable to browse to our vCenter server using Firefox. When I do initially, I get the usual certificate error. Once accepted, I get an error that Firefox cannot connect to the server.

I receive the same error in Private mode as well.

I am able to browse without issue using Chrome which leads me to believe the problem is with Firefox.

Any help would be appreciated.

Today following a brief power outage I was no longer able to sign in to AOL with Firefox on my desktop computer. I am able to sign in to all other apps with no problem. I tried clearing my cache, restarted Firefox, restarted my computer and spent 30 minutes on remote desktop access assistance with AOL trying to fix the problem with no success. I can log in to my account using Chrome on the desktop computer and can log in with no problem using my Android phone but can't log in using my desktop computer with Firefox. I've verified that my Firefox version is updated. I am running Windows 11 Pro.

I would greatly appreciate any helpful advice.

I use the Microsoft Defender Security portal (security.microsoft.com) in the Firefox browser. In this portal, if you click on the "?" in the top right of the page, a flyout window opens and you should see support options on how to get help from Microsoft. On Firefox, I get an error that says "You do not have access to this experience. Please contact your admin to request help and submit a ticket". Microsoft has told me this issue is not a Microsoft issue since this only happens on Firefox and not any other browser. I am seeking help from any Firefox experts to figure out why I am getting this error in Firefox and how I can resolve this issue. I am running version 147.0.1 (64 bit) of Firefox.

Ich habe seit einiger Zeit Probleme mit unterschiedlichen Login Masken die nicht korrekt angezeigt werden.

Z.B. Online Banking, Synology NAS, etc. Ich habe Firefox jetzt schon drei Mal neu installiert, dann geht es gefühlt ein paar Tage, jetzt kann ich mich nicht mehr auf meiner Synology NAS anmelden, weil die Login Seite nicht angezeigt wird. Verwende ich z.B. EDGE funktioniert es einwandfrei!!

Igend eine Idee ?

Mit freundlichen Grüßen

Everytime i try to go on YouTube and click on a video, it says that "that specific content is unavailable", with every single video i try to watch. i tried using a different browser, like Chrome, and this doesn't happen with those videos, only with Firefox. I also tried switching search engines, but it seems as if it still doesn't work.

I'm using Windows 11 with the latest version of Firefox.

A few days ago I went to addictinggames.com and had no problem playing several games. Today I went there and every game I tried I received the following error "Application error: a client-side exception has occurred (see the browser console for more information)."

Then I went to the site using Microsoft Edge and had no problems, every game I tried worked fine.

In Firefox I disabled both Adblocker Ultimate and Ghostery (My only extensions). Before I went to the site I deleted cookies and Temporary Internet Files and I still got the same error. Any ideas?
