Firefox Support Forum

I am attempting to copy values from one google sheet to another and am unable to do so effectively as whenever I press crtl +shift + c I open the the developer tools. All my efforts on looking for a solution have lead me to unsupported extensions so I'm stuck wondering what to do.

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 🤮

TL;DR: Make sure you're on the latest... turn Sync off on the computer that isn't showing the remote tabs, then turn Sync back on.

Details:

Three computers (Windows), a phone, and a tablet. Firefox 124.0.1.

Sync is enabled and generally seems to be working fine. But I just noticed, on one computer, that when I went to Firefox View, and clicked on "Tabs from Other Devices", that it was showing nothing, other than the, "Log into your Firefox Profile", which I was already logged in... so that was messed up.

Did a number of things, like checking the other computer, manually syncing from the other computer, coming back to this one, and telling it to manually sync. It also seemed to be stuck in syncing (a grayed button that said "Syncing...")

I looked, and there was an update available to 124.0.2, so I used this opportunity to upgrade.

When I came back in, I still didn't have the remote tabs showing up, so I turned off "Sync" entirely, but didn't log out of my Firefox account, and then turned it back on.

Now I'm seeing the remote tabs.

That's how I fixed it. I hope it helps. I see others having Sync problems, and getting terrible suggestions that are not helpful. In this case it's the simple thing that fixed it for me. Turn it off and turn it on again. If that doesn't work, unplug the computer from the wall and plug it into another outlet.  ;-) ( That's a joke for those of you with a sense of humor. )

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.

Why has my firefox browser failed to connect with my banking website?

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).

duplicate of /questions/1443841 thread.

I cannot get firefox to update. It is set up for automatic updates but they don't happen. Even if I try manual installation of updates it says the update fails. I ran it in troubleshooting mode and the problem still exists. I restarted my computer and the problem still exists. I am using a mac running on Monterey. How can I get it to auto update again? (and even though it says failed to check for or install updates, it looks like I do have the latest version of firefox)

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.

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
