Firefox Community Forum

Bonjour,

Depuis le 4 août à 14h30, Google Meet ne parvient plus à accéder à la caméra de mon ordinateur portable lorsque j’utilise Firefox ou Chrome. Un message me demande d’autoriser l’accès à la caméra dans Windows, mais les autorisations sont bien activées.

Il est important de préciser que Google Meet fonctionne parfaitement avec Microsoft Edge, avec la même caméra et sur le même ordinateur et que Teams fonctionne avec Firefox.

Par ailleurs, jusqu’au 4 août à 9h30, Google Meet fonctionnait normalement avec Firefox et avait bien accès à ma caméra.

Il semble donc qu’une mise à jour effectuée entre ces deux horaires, soit de Google Meet, soit de Windows 11 (version 25H2), ait pu modifier ou bloquer l’accès à la caméra pour Firefox et Chrome.

Actuellement, je suis donc obligé d’utiliser Teams pour faire mes réunions.

Pourriez-vous m’indiquer comment résoudre ce problème et, si possible, vérifier s’il s’agit d’un problème connu lié à une récente mise à jour ?

Je vous remercie par avance pour votre aide.

Cordialement,

Dominique Turpin

Hi Mozilla Support Team,

We are experiencing a minor layout rendering issue on our online booking platform bookbustour when accessed via Firefox for Desktop.

Are there any specific Firefox CSS compatibility rules or extension settings we should adjust to optimize user performance?

Thanks for your assistance!

I have reproduced a persistent Firefox/Linux emoji rendering issue in ChatGPT and found a small CSS workaround that fixes it.

Environment

Linux Firefox 155.0.1 The problem also reproduces in a completely fresh Firefox profile Noto Color Emoji is installed

Symptoms

In normal ChatGPT conversation text, some common emoji such as:

😄 😂 😀 😁 🙂 😊 🤣 ✅

render as monochrome or outline glyphs.

Other emoji such as:

🚀 🔥 ❤

may render correctly in the same message.

A particularly useful clue is that the same affected emoji render correctly inside ChatGPT code/copy boxes, while failing in ordinary response body text.

Firefox DevTools Fonts inspection showed ordinary fallback fonts including DejaVu Sans, FreeSans and Nimbus Sans being used alongside Noto Color Emoji.

Updating Firefox from 155.0 to 155.0.1 did not fix it, and neither did creating a completely fresh Firefox profile.

Diagnostic test

Running this in Firefox DevTools Console on chatgpt.com immediately fixes the affected emoji throughout the page:

document.documentElement.style.setProperty(

 "font-variant-emoji",
 "emoji",
 "important"

)

Permanent workaround

Using the Stylus extension, scoped only to chatgpt.com:

html {

   font-variant-emoji: emoji !important;

}

This survives a complete Firefox restart.

This appears to be a font/emoji-presentation interaction where some emoji-capable Unicode characters are being satisfied by ordinary monochrome text fonts before the colour emoji font is selected.

Mozilla Bug 1971053 describes closely related glyph-selection behaviour and mentions font-variant-emoji: emoji as a remedy: https://bugzilla.mozilla.org/show_bug.cgi?id=1971053

I am posting this both in case it helps other Linux/Firefox users and to ask whether this remaining behaviour on Firefox 155.0.1 is expected or should be tracked as a current Firefox/web-compatibility issue.

Hi!

We have a intranet site that works in Edge and Chrome without issues with the site added to "internet options". But for some reason we are getting 401 Unauthorized when trying to access it from Firefox. I have tried adding the urls to: network.automatic-ntlm-auth.trusted-uris network.automatic-ntlm-auth.allow-proxies: true network.automatic-ntlm-auth.allow-non-fqdn: true network.auth.force-generic-ntlm: false network.auth.force-generic-ntlm-v1: false

Ingocnito mode , same error. I have tried disabling all plugins. Disabled DNS over HTTPS.

HTTP/1.1 401 Unauthorized Server: Microsoft-IIS/10.0 WWW-Authenticate: Negotiate X-Powered-By: ASP.NET Date: Mon, 25 May 2026 08:15:41 GMT Content-Length: 0

Здравствуйте. Я установил сертификаты по инструкции, которая лежит на s.sber.ru/70VQ2B . После этого в мозилле не прогружается полностью окно входа на online.sberbank.ru, не видно содержимого фреймов (сейчас попробую сделать скриншот). В Microsoft Edge работа нормальная. Удаление сертификатов, перезапуск браузера и компьютера не помогли. На других компьютерах ещё не проверял. Посоветуйте, пожалуйста, что можно сделать. Windows 10, Firefox 153.0.3 (64-разрядный).

Sites struggle to load a lot of the time now, sites like youtube don't load until I clear my browsing history and cookies, some sites don't load at all, some shops don't load any image previews. I've tried on other browsers when these things happen and they don't happen there.

I can't access two websites in Firefox, but I can access them on my phone and in other browsers. One site is Facebook, and the other is https://www.gildertech.com/forum/

Thanks in advance,

I have various sites that won't accept site login credentials but work on other browsers and Firefox is running very slow. If I completely shut down and restart my computer, the logins will work for a few minutes but then stop working again. I've completely uninstalled Firefox several times, deleted my profile and created a new profile. Ran Firefox in troubleshooting mode with extensions turned off. None of these have had any effect. I recently saw a post that this might be a Firefox issue with version 154.00. I'm currently running version 154.01. Is this actually a Firefox issue or do I need to continue to look further into my computer and router for the problem?

bei Ebay werden die angebote falsch angezeigt, zum bespiel kann ich nicht sehen da eis ein Preisvorschlag ist. nach löschen der cookies auf der seite ist die ansicht richtig und wenn ich mich eingeloogt habe ist wieder alles falsch, echt nervig.

Has anyone reported this before? I am working as a contractor for a BigTech company. I am using an online platform/tool of theirs for several years now but after a recent update the work area doesn't show scroll bars anymore. That means I cannot scroll the editor window and can't go beyond the first page. This makes working (and earning money) almost impossible. As even for the tiniest edit I have to download huge tasks which is extremely time-consuming. An inquiry with my manager there indicated that other contractors on firefox experience the same issue. so they consider it a firefox compatibility issue of some kind. They gave me the advice to use Chrome, Edge or Safri instead. Well, I use firefox because I do not want to use Chrome/Edge... Don't know about Safari but my PC is on Windows... Any idea what can cause it and how to resolve the issue?

For some reason, my Gmail page doesn't show the icons on top at all. Like the archive, mark as read, and the others on top of the mailbox contents. They show up on both Chrome and Edge, so this seems to be a Firefox problem.

Computer being used with issue: HP ProDesk 600 G2 DM (Windows 10, 16GB RAM) So can this be fixed or should I just use my phone for Gmail?

I am suddenly finding I cannot scroll a thread in Chatgpt! What changed in the last 2 days? It has been working fine for 2 years. I am on OS mojave 10.14.6 on a 2015 Model Imac.

... click on (eg.) 'Interactive Map' and nothing happens, at least not here. Chromium has no problem.

Depuis Firefox 150 il ne m'est plus possible de Glisser-Coller un dossier avec ses fichiers dans un dossier de mon NAS Synology. Le service d'assistance Synology m'a apporté confirmation. Voir sa note en attaché.

Il semble qu'il y a un "bug" dans Firefox 150 et plus (j'ai le 155.0.1) pour ce Glisser - Coller ?

Que puis-je faire ?

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
