Thank you in advance for your advice.

This one really caught me by surprise! I have an internal Django database system. Staff typically use Firefox or Chrome to access it from Linux or Windows machines. As part of this system, it uses Grappelli library which in turn uses TinyMCE V3.5.8. Specifically, in a text box TinyMCE provides advanced editing and fonting. Allows the user to embed links or images. This system was working fine on Django 2.2. My provider (Python Anywhere) retired the server image I was running on, so I updated everything to Django 4.2 on their latest "haggis" system image. Everything seemed to transfer over without any errors - at first. In fact, it was a week later somebody tried to change a font colour by clicking the popup button that opens a colour picker. That pop up looks blank! (its not, the HTML is there but without the custom CSS nothing is visible)

In developer mode on Firefox or Chrome I can see what the problem is: The popup is disconnected from the parent. The parents CSS and classes - specifically tinyMCE - is not present. So its missing the styling and JS to operate. One of the first things the popup JS does is copy in the tinyMCE and tinymce classes from the parent. But they are not there, in fact .opener is null and .parent is stripped down.

What is really weird is on my test server, where I tested everything before updating the live server, it works! The test server uses Django's "runserver" to run a very simple (unsecure) http server just to test code. Whereas the live server is locked on HTTPS.

What confuses me is I don't see any console log messages that would indicate the browser decided to "protect" me. How can I figure out what is going on? Or disable this feature for a test?

I am writing this on my Dev machine using the browser I test with, so I shall try to paste in tech info below.

Just to reiterate, in this browser I can have my test server in one tab, my live server in another tab, test server popup works; live server popup does not.

Thanks in Advance, Richard

Dear Firefox Support Team,

I am experiencing an issue with Firefox where it unexpectedly closes without any warning or generating a crash dialogue. This issue occurs when switching between any tabs, not exclusively ones with active media content such as YouTube, as previously suspected. This problem has persisted across multiple instances, without a discernible pattern or specific tab content causing the issue.

• • Firefox Version:** 124.0.2
  • Operating System:** Ubuntu 23.10, Linux 6.5.0-27-generic
  • Extensions/Themes:** [Provide a list of enabled extensions, or note if the issue persists in Safe Mode]
  • Recent Changes:** [Mention any recent system or Firefox updates]
  • Graphics Card:** NVIDIA GeForce RTX 3070 Ti, Driver Version 535.161.07

• • Steps to Reproduce:**

1. Open Firefox with multiple tabs. 2. Switch between various tabs. 3. Observe that Firefox occasionally closes unexpectedly without any crash report dialogue.

• • Attempted Solutions:**

- Checked `about:crashes` with no submitted crash reports found. - Monitored for errors using the Browser Console but found nothing consistently leading to the issue. - Attempted running Firefox in Safe Mode to rule out extension-related issues. - Disabled hardware acceleration to see if it impacts the occurrence, with no change.

• • Relevant Logs and IDs:**

- **Crash IDs:** N/A as no crash reports have been generated. - **Console Errors:** No specific errors noted that correlate directly with the issue. - **about:support Data(sanitised):**Name: Firefox Version: 124.0.2 Build ID: 20240401114208 Distribution ID: mozilla-deb Update Channel: release User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:124.0) Gecko/20100101 Firefox/124.0 OS: Linux 6.5.0-27-generic OS Theme: Generic Application Binary: /usr/lib/firefox/firefox-bin Profile Directory: [Generic Profile Directory] Build Configuration: about:buildconfig Memory Use: about:memory Performance: about:processes Registered Service Workers: about:serviceworkers Multiprocess Windows: 1/1 Fission Windows: 1/1 Enabled by default Remote Processes: 14 Enterprise Policies: Inactive Google Location Service Key: Found Google Safebrowsing Key: Found Mozilla Location Service Key: Found Safe Mode: false Memory Size (RAM): 15.4 GB Disk Space Available: 1,468 GB Profiles: about:profiles

This problem significantly disrupts my browsing experience, and I have not found a consistent workaround. Any insights or assistance you can provide would be greatly appreciated. Please let me know if further details are needed or if there are any diagnostic steps I can take to help resolve this issue.

Thank you for your time and help,

Actually my problem was solved. It came from the fact that following a maintenance intervention on the servers of the https site where my account was located, and access to which was blocked by Mozilla, the automatic updating of certificates had not worked. Which the site technicians resolved following a request I sent to them.

Currently, I use Firefox version: 116.0.2 on Ubuntu 20.04.6 LTS.

I encountered a phenomenon like this:

• When I logged in to the application, in the tab I was working on, the Firefox session memory was lost (don't open new tabs)

What is the cause of this phenomenon? How can I fix it?

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?)

Recently firefox stopped filling in my credit card information. 1. On a website asking for a credit card click on the credit card number box. 2. Choose the car from the popup. 3. Popup disappears but nothing is filled in on the website form. 4. Use Google Pay or PayPal to purchase.

This used to work.

Firefox version 125.0b9 (64-bit) Ubuntu 22.04 Firefox installed from the Mozilla PPA - ppa:mozillateam/firefox-next

In Chrome, I can hit CTRL+SHIFT+I to open developer tools, add the Media tab, and go to the Media tab, and I can see the codec and what decoder is being used.

How do I do the same thing in Firefox?

Why you create Mozilla account with sync, if I can't use profile which I saved on my old PC. I change my PC and now I can't use my open tabs as needed, I need to open each tab one by one. Why ??? Why I can't use saved profile on my new PC ??????

I using kubuntu (ubuntu with kde) 22.04 and firefox will not recognize my security key. There is a really good thread on this here. It is now closed.

https://support.mozilla.org/en-US/questions/1412073

One of the solutions is to install firefox from the mozilla server. On other forums, this is referred to removing snap and installing the debs. I haven't tried this.

Reading through the thread however, it seems like the snap version should work. The manufacurers id and product code for my Thetis FIDO2 usb key are present in the etc/udev/rules.d/70-snap.firefox.rules

This answer says to disable apparmor. I tried that, but it didn't work.

I have quoted this answer below.

This isn't actually a firefox problem. KDE Neon uses the firefox package from the Mozilla Team PPA and there's nothing wrong with that package. The problem is that Neon enables app armor on firefox which breaks access to password managers and security keys. sudo aa-disable usr.bin.firefox works around the problem by disabling app armor for firefox. aa-complain was not sufficient in this case.

Is there anything else I can try?

Hello, I administer a small fleet of Ubuntu desktops. For a variety of reasons we avoid using Canonical's Snap package version of Firefox.

Currently the fleet is using Firefox installed from the Mozilla Team PPA repo. However that repo can be incredibly slow and after reading about the new Firefox deb packages [1] from the Mozilla APT repository we would like to move to them. The problem is that these packages lack Apparmor profiles, so unfortunately my security team won't let me use them.

Would it be possible to add Apparmor profiles to these packages please? They would need to be applied only when an OS has Apparmor enabled, which may not be the default for Debian.

Thank you!

Until recently, whenever I downloaded a file, the Firefox dialogue requesting the destination folder started out at the folder I last used to download a file from that web site. Now it appears to always start in the last used folder, independent of web site. Since I seldom download more than one file at a time from a given web site, this means I have to navigate the directory tree for every download, which makes the whole process take two or three times as long as it used to. Is there any way to restore the old behavior? My searches on the web have only turned up suggestions that are accompanied by responses that say "That didn't work." (Running 101.0.1 on Ubuntu 18.04, if that matters.)

I know there are add-ons that will let me script the download folder selection process, and I'll go that route if I must, but I'm hoping that my preferred browser behavior is still available - "just works" is preferable to "you can beat it into submission if you try hard enough".

PSA:

The snap version of Firefox (as implemented in Ubuntu Desktop 22.04) will not open a Zoom meeting link.

The alternatives are: - Google Chrome, etc. - Borrow a Windows machine and log into your meeting there.

What a disaster.

Firefox 101 Xubuntu 20.04

I want to completely disable the Firefox pop-up notifications regarding updates. I have searched the web for an answer and cannot find anything workable. Can you please tell me how to accomplish this as the constant nagging is extremely annoying.

In about:config I have the following set with no success:

app.update.auto false app.update.download.promptMaxAttempts 0 app.update.elevation.promptMaxAttempts 0 app.update.enabled false app.update.interval 31536000 app.update.promptWaitTime 31536000 app.update.silent true browser.search.update false update false

I am on ESR 78.15 Oesr (64 bit) should I stay on it or move to another version of Firefox if I am a web developer? From what I can gather they are the same? I am on debian linux kde

I haven't used my microphone in Firefox in years. I tried today, logged into Google Voice, which tells me it can't access the microphone. I set permissions in Firefox's settings. I turned up all the mic settings in alsamixer. I tried https://mdn.github.io/web-dictaphone/ , recommended in another thread here, and it doesn't record either. I can use the microphone outside X, with sox's rec. I also can't record a new greeting in Google Voice.

Firefox 100.0.2 , Linux, Slackware 64-bit, all packages updated this morning.

Hello everyone,

I need to disable all videos from ever playing no matter what for medical safety reasons, does Firefox allow this?

I've already found the option in the config to disable GIFs. Turning off autoplay is not enough.
