Hi, I use the Firefox Developer Edition for Windows Desktop (112.0b4 (64-bit) on daily basis. When I play the Udemy DRM content nothing goes wrong first and the browser loads the page well. But after some time passed I see that Firefox stops to load the page and the tab spinning infinitely. Pressing the realod button doesn't help. The only solution is to restart the browser. I use no-proxy setting. The refreshing of the browser didn't help either. I have configured the following options in the "about:config" but it didn't help as well: network.dns.disableIPv6 : true network.dns.disablePrefetch : true network.http.http3.enabled: false

Hi lovely People, I try to setup 2FA on accounts.firefox.com with Authy on Android. In Step 1 the code generated from Authy is accepted.

But then, in step 3, when I try to paste in the just in step 2 provided backup activation code, it tells me it's wrong. Am I stupid? I just copied that key from step 2 ... I tried it many times now. Checked if my clipboard is working as expected, tried to delete the spaces in between... I used FF Standard and FF Developer Edition. My Authy is working elsewhere.

Any help? I searched the Forum, found some relating questions, but they never get answered. No one having the same issue?

Hi,

im getting unknown issuer on my thin-clients with a FF ESR 45.9.0. This FF is tied to the OS (Ubuntu 16.04) and the OS is the most recent compatible version for our version of the thin-clients. So yeah its super old and I'm not able to update any of this. There is no security.enterprise_roots.enabled option available. What would be the best way to solve this issue for ~400 clients. Thanks in Advance Regards Tekkion

YouTube videos on Firefox Android Stable, Beta, and Nighty, experience significant frame drops when viewing "Stats" both on AVC1 and VP9, and on all resolutions. I checked about:config in both Beta and Nightly and HW acceleration was enabled. This was true for a FRESH install as well. I tried this on other devices and the problem persists. Mull, which is a fork of Fennec, plays the same videos without any problems. Other browsers are also fine.

Tested on Samsung S20 One UI 5.1 (Android 13). Tested on Samsung A13 One UI 5.0 (Android 13). Tested Sony Xperia XZ2 Compact (Android 10). Tested on Sony Xperia XZ1 (Android 9).

I recently installed new pc with fresh Firefox Developer Edition. Then I transfered the profile folder from old pc to the new pc. All bookmarks, addons, etc is there. Just the XULRunner popup appears only on the new pc. I uninstalled firefox on the new pc again and reinstalled it with profile cleaning. After profile cleaning firefox got faster and addons got removed. But the XULRunner popup keeps appearing. When I go to taskscheduler and trigger the "Firefox Developer Edition Background Update CA9422711AE1A81C" again, the XULRunner popup appears. Removing this taskscheduler and Firefox keeps readding it and the XULRunner popup are back. Any idea how I can get rid of the XULRunner popup?

The blocks where code should be displayed like on screen and on stackoverflow displayed in a weird manner : replaced with [Object object] i don't have any extensions that might cause that

I am using Firefox Developer Edition Version: 110.0b5 (64-bit) on M1 Mac running Ventura 13.1.

I am building an webapp some XHR triggering in background but it is not necessary to run the application (running fine on other browsers). But on Firefox Developer Edition, It shows a error window with the message and stops loading the application.

Firefox can’t establish a connection to the server at localhost:4000.

localhost:4000 is the failing XHR request domain. I have attached the screenshot.

How to ignore the XHR failing errors just like other browsers?

Lately in Google Drive I get this error when I select one image or a file: Impossible load details. Retry. I have Firefox 108 version, on Edge and Chrome all is OK. Also the troubleshoot mode doesn't resolve the problem.

Firefox Developer Edition - Developer Console is killing my productivity. It started opening in Full screen mode about a week ago and will not exit full screen. I have to F12 and exit developer console. This is a major issue because, I work with the console not docked. Docking blocks my productivity. F11 only puts it into some very weird outline mode where all I see is a rectangular grey outline on my full screen. If I click on it, it repaints the console in full screen. There is no option to drag and expand or contract. Nothing. Nada. Please help. This is my primary browser, er -was my primary browser. I'll continue to work around it until my patience is completely exhausted. Almost there now.

Sorry about the terrible markup on the screenshot. It's hard to encircle a big gray full screen empty frame. Thank you.

I upgraded Firefox to 109.0 on OpenSUSE Linux today as an update. Firefox no longer plays videos. Chrome is still playing the videos, so the codecs are on my machine. Is there anything I can do to fix this?

I'm trying to sync my bookmarks from Firefox mobile (Android) to my laptop (Dell) for the first time but there's no "Sync and save data" option under the dot menu on my phone nor is there any equivalent that I can find. How do I proceed?

I use the Windows registry FontSubstitutes (Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes) to replace system fonts like Segoe UI with other fonts. It takes a lot of work to get Windows itself to respect these options, to the extent that I have to make it believe Segoe UI isn't present by modifying a different registry location (Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts).

However, Firefox does not respect the FontSubstitutes settings. Based on a previous post here, this is something it did prior to Firefox 89, but has stopped doing.

An ideal solution would be a way for Firefox to correctly read my FontSubstitutes settings. An acceptable workaround would be a way to provide Segoe UI for Firefox to use while still preventing its use in other applications. (I know that, for instance, Adobe Photoshop allows users to install fonts to Photoshop itself, bypassing the system fonts folder entirely.)

Clicking the mousewheel still works, but scrolling doesn't work. This behavior occurs on tab bar as well.

Using option "Restart with addon disabled" from about:profiles can make the mousewheel scrolling work, but manually disabled all addon and restart just won't solve it.

Since upgrading to Monterey, Google search pages show almost no text in Firefox. Google searches in Safari and Google Chrome are completely fine. Only Firefox is showing the problem. The blank text includes dropdown menus too - all options inside them are blank. Currently on Firefox v107.0, but the same problem happens with older versions.

If I go into Troubleshoot mode, the Google searches are working fine. I have refreshed Firefox, Cleared the startup cache. But the problem persists. I uninstalled Firefox from the machine, restarted the computer. Did a fresh download and install, haven't signed in so there are no addons/extensions to cause problems.

This is happening on both an Intel Mac and an M1 Mac running Mac OS 12.6 Monterey.

I attach one screenshot showing the same page with and without troubleshoot mode on. The second screenshot shows another page of results including what looks like weirdly encoded characters.

I've followed all the suggestions in the support page but nothing has helped. I'd really appreciate any advice on further troubleshooting. Thanks in advance for any help.
