Firefox Support Forum

I'm having a pretty frustrating developer experience using Firefox to help develop an app that uses Server Sent Events. Now, I'm not sure if I'm the one at fault or if it's something to do with Firefox itself (most likely I'm missing a config option somewhere).

Anways, the issue I'm having is that I cannot seem to be able to see Server Sent Events in the network tab of dev tools. This is specifically what I'm looking for: https://firefox-source-docs.mozilla.org/devtools-user/network_monitor/inspecting_server-sent_events/index.html

I'm testing this functionality by going to https://sse.dev/testpage.html, opening my network tab. I can see the connection to the SSE endpoint however, all I see is "No headers for this request" or "No response data for this request". I know it's getting the data through the event source because I can do stuff with the data. I've also tested this in Edge and everything appears in their network tab as expected which, makes me feel like this is more of a browser-specific issue. Again, I feel like it's me missing a config somewhere or having a privacy setting set which is somehow messing with the event stream.

Any help is appreciated... I guess I got to use Edge for the time being 🤮

I have Firefox on 3 devices, I deleted several passwords from 1 device expecting this change to sync to the other 2 devices. Instead for several days the 2 devices showed the original number of passwords whilst the device I made the changes on showed the new amount. Now that device appears to have resynced the passwords I deleted. Am I supposed to delete them on each device?

I have the latest version of FF on all devices.

Clicking on a link in a Thunderbird email does not cause Firefox (the default browser) to open that link. If either Chrome or Brave is set as the default browser, they will correctly open the link. Obviously, the problem is with Firefox, not with Thunderbird. I raised this issue several years ago and have never received a response. I have drastically reduced my use of Firefox accordingly. I am primarily a Linux user (Ubuntu 20.04 LTS, gnome shell 3.36).

When editing in Gmail, holding a key down does NOT repeat the character or action. e.g. xxxxx when holding down the "x" or deleting multiple characters when holding down the <Backspace> key.

It works properly in other apps (e.g. this dialogue).

And works okay in Gmail in other browsers (e.g. Chromium or Brave).

I'm using Firefox 124 on Linux Mint 20.1.

System: Kernel: 5.4.0-174-generic x86_64 bits: 64 compiler: gcc v: 9.4.0

I am using the latest version of firefox. Windows 10. I'm writing a school project with assistance from ChatGPT. When I ask it for a link, it provides it. While it is "typing", I can see the link, but when it finishes "typing", the link becomes a blue word "Link", with the web address gone. I can not click on it to open the website, like I can in Mirosoft office. There is no way to access the website. I tried to use troubleshooting mode with all extensions disabled - it didn't help. ChatGPT claims, that it's the browser issue. How can I access these links?

So I have a following problem

FF 124.0.1 Windows 10 N edition Installed media feature pack

When trying to play twitch video it shows error 4000 and when trying to play stream from youtube it shows that your browser can't play this video.

Problem is that FF was able to do it like 6 moths-year ago (not really watching stream videos)

was trying to reinstal media feature pack, firefox, chcecknig nighgtly build but without sucess and have no clue what can do more

I want to use a key to open Speed dials in the same tab and same key with 'Shift' to open that speed dial in a new tab.

My favourite were Ctrl+1, 2, 3, 4 ... and so on. And when I used Ctrl+Shift+1, 2, 3 etc, then they opened in a new tab. But now the Ctrl+1, 2, etc are focusing already open tabs. How to revert to old behavior of these shortcut keys?

I've read several articles on using extensions like 'Shortkeys (Custom Keyboard Shortcuts)', but those don't let me use C+1, 2, etc. Also another method of using to js files (auto.js something) doesn't seem to do this job, as I think that would only disable some KeySrtcs altogether.

Firefox takes a very long time to open the first tab. After it opens, subsequent tabs open relatively quickly. I've tried self help suggestions like clearing cookies, cache and history, updating, even removing home page content. Nothing helps. It's getting intolerable and I end up switching to other browsers rather than sit and wait. Starting to even dread using firefox. Running Sonama 14.3.1 on my iMac. What else can I do?

see my screenshot: 1. this smal ? arrow - show tab titles- how can i disable in about:config 2.other symbol -extensies are empty...how can i add here my addons? 1- i dont have it in my desktop and 2-in this desktop i see all my addons, in this symbol.these screenshot are from my new laptop...

in my account my questions here ,in this firefox forum , i see my questions about... thunderbird! its strange,right? i look for my questions and asnwers in this forum. so where are they ?

I am facing issue while downloading files in Firefox Private Browsing. Whenever I download my PDF files, as soon as I close the browser window, the files also get deleted automatically. What should I do to rectify this issue.

I'm having this exact problem from here , but browser.taskbar.lists.tasks.enabled has always been set to true. Toggling it does nothing in itself in between restarting my machine. I am certain it's not a jump menu thing because this isn't about shortcuts (and besides the point, enabling the jump shortcuts from my OS side of things does not display it either way). I just want the stuff that the user in the above link listed.

Coincidentally, I had this exact problem a short while before, and I think it may have had to do with an update, because I remember Firefox updating at least twice fairly recently and it is in this time I've noticed this issue. The first time around it resolved itself, but this time it has not and I do not know the cause.

Unpinning/pinning the icon on the task bar does not resolve this either. It seems none of the conventional solutions in the past work, so unless I am missing something, something broke.

I have been watching SBS OnDemand successfully until today. I now receive a consistent Video Playback error on any video using Firefox Ver 124.0.1.  I do not have an Adblocker installed. (Windows 11 Pro 23H2).  I do have AVG Internet Security installed.  I installed no apps. I turned off Enhanced Protection for sbs.com.au in Firefox but the problem persists. The problem does not occur on Chrome.

Hello everyone,

I posted my issue on the french speaking forum a few days ago https://forums.mozfr.org/viewtopic.php?t=153652&sid=96223ded5b326b4da4114d4c0fb4b740 I think I've had this bug since the last update of Firefox. I have checked on other browsers (Edge and Opera), and I have no problem with them. Its also ok on my mobile phone ... with Firefox !

Thank you for your attention and any help you can provide.

Regards Damien

Fiz a configuração para sempre perguntar onde salvar arquivos nas configurações, em aplicativos em "Tipo de Conteúdo" selecionei o PDF para "sempre perguntar". Acontece que quando seleciono para abrir o documento pelo adobe ou pelo firefox, ele está está salvando na pasta Downloads automaticamente, e eu não quero que salve. O meu Firefox está atualizado na versão 124.0.1. Windows 10 Pro 22H2. Meu Firefox está salvando os arquivos PDF na pasta Download mesmo eu não querendo salva-los. só quero visualizar. Enviei imagem da minha configuração.

Obrigada

Please help.

I have always loved Firefox. I started using it because it did not constrict the user to the limits of the narrow minded Microsoft Explorer (Edge). But, this latest update reminds me of what I came to Firefox for. I hope Firefox is not going to become the same way. This latest update (124.0.1) just didn't care about my bookmarks or extensions or anything. It just installed a new version and left it at that. I had several tabs open. Gone. I had several bookmarks. Gone. All extensions. Gone.

For a long time Firefox just updated and left all of those things in tact. What happened?? More importantly, does anyone know how to get these things back?

I would really appreciate your help.

Thank you, Luke

I installed Firefox on a new computer running Windows 11. I use the X-notifier plug-in to access my Gmail account but can't get X-notifer to run properly on this new install. I was getting an error message, but now it says "Can always read and change data on this site" yet the envelope icon does not appear in my tool bar like it does on my old computer.

As an alternative, I signed into my Gmail account so I can read my email on a browser page. While that works, it works too well -- as soon as a new email arrives, the browser tab running Gmail pops to the top and interrupts anything that I am doing -- even when I am typing a new email or filling out a form on another tab.

The only way I can deal with this is 1) sign out of Gmail until I want to check it, or 2) pull the Gmail tab to a separate window and minimize it so it can't interfere with what I am doing.

I'd like to know if there is a fix for the X-notifier plug-in or a way to stop the Gmail tab from "taking over" the browser.
