Firefox Support Forum

I've had this issue ever since switching to a new laptop. This issue is specifically within Firefox (I have tested this in other browsers and programs, and the issue isn't there. Everything else works perfectly fine!)

Essentially, whenever Firefox plays multiple sounds at the same time (for example, I use both youtube and discord in-browser) the second sound will briefly mute the other sound. (Going back to the discord-youtube example, if I am watching a youtube video and recieve a discord notification, the youtube video will pause for about half a second.) Or if a site has background audio but also plays a short audio clip when certain elements are clicked, for example, it will cause this "overlapping" issue. Again, this issue is only within Firefox.

I am using Windows 11 if that helps. I've already tried using a Firefox Refresh and peeking in about:config but I'm totally lost as to what I can try next, since I can't find any other examples of people with this issue online. Sometimes the issue briefly fixes itself but then reappears.

I’m using the official ShadowsocksX app to relay network connections through a Shadowsocks server, and Firefox seems to be having compatibility issues. The browser does not load pages when proxy settings are set to “auto-detect” or “use system:” I’m getting the “Unable to connect” error message. Manually setting the SOCKS host to 127.0.0.1:XXXXX does fix the problem, but that also means I have to switch back to “system” whenever I turn Shadowsocks off.

Neither Safari nor Chrome requires manual action to relay connections on the same computer.

On a different computer, I’m using the Outline client to connect to the same Shadowsocks instance. Firefox does not have issues with that.

When attempting to load a number of different web pages such as Quickbooks Online Apps, the page displays "Loading Apps..." with a spinning wheel, but never redirects to the Apps page; the site hangs forever. On other browsers there are no issues; it eventually switches to the correct page. In Firefox Browser I have tried adding exceptions in Settings --> Privacy & Security --> Manage Exceptions. No change. Thoughts?

I added the Save to Pocket (mini) extension to Firefox 125.0.2 today. When I look at the collection of articles I've saved to Pocket (I've been using Pocket for years) in the browser, I only see 8 articles. But when I open Pocket on my iPhone and iPad, the list of articles I've saved is much more longer (an estimate would be between 50 and 75 articles saved to Pocket). I haven't found any articles in Mozilla support to help me solve this. Thanks

My primary/default browser is Firefox on Sonoma 14.4.1, and recently I'm unable to use the inputs of my audio interface for google hangouts. The relevant output is correct, and my system audio would be the same.

I've recently started using the Tree Style Tab extension, and I'm finding it useful, but I'd like it if the list of tabs could be automatically hidden when only one tab is open (and automatically shown when more than one tab is open).

I hoped to write an extension to do this, but opening the sidebar from an extension requires a user gesture, so I suspect I'll have to use a userchrome.js script.

From a "userchrome.js"-like environment (i.e. unsandboxed AutoConfig), I can hide and show the sidebar with `SidebarUI.hide()` and `SidebarUI.show("treestyletab_piro_sakura_ne_jp-sidebar-action")`, and I can examine the tabs open in the current window via `gBrowser.tabs`, but I can't see how to get notified when the number of tabs changes (replacing `gBrowser.tabs` with a proxy doesn't work, for example). I suppose I could just check every few seconds? That feels like a bit of a cop-out, though, and gets more and more inefficient the more windows are open.

There's an API for extensions to receive events when tabs open and close, so clearly this is possible. Where should I be looking for this functionality?

(I also don't know how I would go about unregistering an event listener (or cancelling a setInterval call!) when the window closes, assuming that's necessary to avoid leaking resources – is there an event like `chrome-document-global-created` I could listen for, but that fires during teardown of the window rather than when one is created?)

I have Ubuntu 22.04 (on a Dell Optiplex 3000) with a minimal installation. I downloaded Firefox 125, removed the SNAP Firefox and installed this Firefox with no issue. I can run "firefox --kiosk" and Firefox runs in kiosk mode with no issue.

I have made some changes in the "about:config" part of Firefox. I have also made some changes to the Ubuntu keyboard shortcut list. There is only one user created on this system and I have configured Ubuntu to login this user automatically upon reboot.

However, if I setup Firefox --kiosk to start automatically (I use the gnome-session-properties application to achieve this) and then reboot, Firefox does run, but it does not appear on the screen. If I enter the "switch windows" keyboard shortcut (ALT-TAB), the Firefox kiosk appears.

So, is this something I can fix by changing the Firefox configuration, or is it an Ubuntu configuration change. If so, can anyone tell me what I should do, or have an idea how to debug this?

I'm new to firefox and would like to set cloudflare for DNS over HTTPS but there seems to be an issue. If I set it to NextDNS the connection stays active. But if I set it to cloudflare it goes inactive with the error (NS_ERROR_NET_TIMEOUT_EXTERNAL). I tried setting a custom DNS to OpenDNS and got the same error.

I'm running Manjaro Linux if that make a difference.

I've made an extention which works fine when I test it using the temp mode on firefox. When I attempt to install from file however I'm told it could not be installed as it appears to be corrupt. Below are the package.json and the manifest.json:

package.json

{

 "name": "ext",
 "version": "1.0.0",
 "description": "",
 "main": "contentScript.js",
 "scripts": {
   "test": "echo \"Error: no test specified\" && exit 1"
 },
 "keywords": [],
 "author": "",
 "license": "ISC"

}

manifest.json

{

 "manifest_version": 2,
 "name": "SKUORG",
 "version": "1.0",
 "description": "Organises SKUs on WooPage",
 "permissions": [
   "activeTab",
   "webNavigation",
   "<all_urls>"
 ],
 "content_scripts": [
   {
     "matches": ["<all_urls>"],
     "js": ["contentScript.js"]
   }
 ]

}

I have tried on two devices / installs of firefox and have followed the steps I could find on this page : https://support.mozilla.org/en-US/kb/unable-install-add-ons-extensions-or-themes#w_corrupt-extension-files

If you have any suggestions please let me know.

Firefox takes about 5 minutes to load every it launches, before working smoothly like it should. This problem occured first time yesterday morning, and I have no idea what could have caused it.

It happens :

• when I launch firefox normally (whatever the profile)
• when I launch it from the terminal (it provides no output at all)
• when I tell it to launch the Profile Manager (5 minutes to see the Profile Manager appear, then 5 more minutes to launch firefox using the selected profile)

It does not happen :

• when I click "New Window" inside an existing firefox process
• when I call `firefox --help` from the terminal

Here's what I've tried :

• First, I've seen pretty much every article from Mozilla Support, Reddit or SuperUser (writing this question is kind of my last resort)
• I've tried removing and then reinstalling Firefox from Flatpak, from the Fedora repos (using `sudo dnf install firefox`) and using the manual install via the archive (v125)
• I've tried downgrading firefox (when using the package manager install) from v125 to v124
• I've also tried the Firefox Developer Edition, same problem here
• I've tried using the "Refresh Firefox" feature and restarting in Troubleshoot Mode (both are also affected by the slow startup, which makes them particularly painful to execute)
• I've tried manually deleting the `~/.mozilla/` folder (= manually deleting my profiles)

When firefox launches, it does not freezes my OS and does not seem to use many system ressources : CPU usage is normal, RAM as well, and it does not seem to read many things from the disk as well (I've seen some threads where this was the issue).

And here is something interesting that I discovered :

• loading (including refreshing) `about:profiles` is also slow and this time freezes firefox (OS reports it as not responding, I can't switch tabs and I can't see my mouse). Other about pages seem to work fine (although I did not try them all)

Thanks !

PS : Even if I think it has nothing to do with the issue, I prefer to mention it here : I was messing with virtual machines yesterday when the issue occured for the first time. My disk got full at some point and I don't know but it might have messed with firefox. At this stage, I had not deleted any files that could relate somehow to Firefox, that's why I doubt it would have caused anything harmful to Firefox. (instead, I mounted an empty partition from my disk to get some space)

The increase happened here: /storage/permanent/chrome/idb/3870112724rsegmnoittet-es.files/

79 files taking 590MB created in 3 minutes, out of nowhere. Why were all these large files created?

Using Linux Mint, Firefox 125.0.2

Several instances of this "verification.exe" malware appear on download history when firefox is opened as shown. Remove from history or clear downloads doesn't eliminate them. They reappear whenever firefox is opened.

Suggestions to eliminate this nuisance welcome.

I don't want to be able to scroll the page by selecting text. That's what the scroll wheel is for. More often than not this 'feature' just results in frustration as scrolling the page selects more text. Can I just disable this altogether somehow?
