Per [https://support.mozilla.org/en-US/kb/control-personal-device-local-networ...] I was looking for Settings > Permissions > "Local network devices" but the option was not present.

Looking at about:config network.lna.blocking I found it set to "false" by default. Only after I changed this to "true" did the UI shows the "Local network devices" configuration option.

Why is this disabled by default? Isn't this a security risk? It seems like users should be notified by default and have the option to block these requests.

Whenever you go to close a folder from the bookmark menu in the browser sidebar, having scrolled down due to a long list, the menu will not only close the folder but also make you click whatever was in that mouse position on the menu with the menu closed. This means closing a folder having scrolled down will cause you to potentially click open another folder or bookmark unintentionally. This is not an issue on the old bookmark menu, but using that isn't as convenient as the sidebar is.

Since a while, I think it is since I created an extra testprofile with "firefox-esr -P", but I've set my main profile as default again

When opening a link in another program than firefox I get always: a popup "Close Firefox" "Firefox is already running, but is not responding. To use Firefox, you must first close the existing Firefox process, restart your device, or use a different profile."

I do have both firefox and firefox esr, I usually use regular firefox the second came with the debian 13 repository.

I keep the esr to test display issues for reproducibility on my personal desktop, because I manage debian 13 kiosk-style desktops with firefox-esr.

(I noticed also that the regular firefox profiles can not be opened in firefox esr, so I use an extra profile for esr)

Hello,

I just upgraded to the latest FF version 147.0.2 64-bit and now the video's on Facebook stop playing when I change to another window. As soon as the FB windows is not selected (in focus) they stop. Going back to the FB window, the video can be restarted.

Can you please investigate/fix this? Thanks!!!

Today when I went to play spotify on Firefox browser it said playback of protected content is not enaybled and at the top it says "The WidevineCdm plugin has crashed". Ive tried everything I could think of and possibly do.

Ive tried: Restarting my computer Deleting and reinstalling Firefox Using troubleshoot mode Disabling Widevine plugin Refreshing the page Toggling DRM content off then on again and ive submitted all crash reports

Im just not sure what to try next, if anyones experiences this before and has bypassed it somehow. Please share

When a video is popped out, in PiP mode, and the "owning" page is scrolled such that the video "origin" scrolls off the viewport, the PiP video pauses. If the video is started again, and the page is scrolled more, it will re-pause.

This seems to be a Firefox behaviour and not a site-specific one.

Is there a setting to keep the video to continue playing?

This would be helpful on Twitter/X, for example, when scrolling the timeline with a PiP playing from a tweet.

I'm afraid the community may be tired of me, but it seems this is the only help Firefox is willing to provide for my problems. First, I still can't get the History and Bookmarks to show, although for a while they did. On top of that, a new issue has developed. Firefox exe now shows on my desktop as well as where I actually want it, in the taskbar. When I try to move it from the desktop, the app is deleted from both areas. When I go back to my apps folder, where I choose to keep exe files, and create another shortcut to go in my taskbar, it gets put back on my desktop and the cycle repeats. With all that nonsense going on for a month or more (I've really lost track of the days and hours I've spent on it), my question is should I just uninstall Firefox, reinstall it and then try to get my History and Bookmarks back. Or what would be a better solution? Whoever helps me with this mess has my sincere gratitude. I've used Firefox as my browser for many years without ever having any trouble and am baffled by what's going on now.

This has happened a few times and confused me but I figured it out tonight. I had a private window open and a regular window open and closed the regular one. When I reopened the regular one all of my pinned tabs were gone. This should be fixed, Firefox should differentiate between the windows and stop closing tabs on the regular window if it's closed before the private one. Kind of an odd thing.

I was able to recover my tabs with a json file thankfully but haven't been able to do so before as I had opened and closed multiple windows trying to figure out where the pinned tabs had gone and the "previous.json" had changed to those new open tabs. It might also be nice to have a few "previous.json" files be created instead of the single one for instances like this.

My bookmarks in the bookmarks toolbar have disappeared, I can no longer save a bookmark anywhere. Some of my bookmark folders have disappeared. I have tried restoring but I get the message "unable to process backup file"even after importing the file from my other laptop using both HTML files and .json files. I tried refreshing firefox, that didn't help. I uninstalled firefox and reinstalled it with the same results. Never had a problem with firefox before, but it's useless now! Can anyone help?

this feature absolutely DOES NOT WORK on ANY Firefox desktop browser on MULTIPLE machines I have tried - and actually I'm pretty sure I can say the same thing about the ANDROID app too?

I can confirm EVERY SITE I have trouble signing in using Passkey on Firefox I can SUCCESSFULLY sign into on Chrome - every single time - the issue is clearly the BROWSER

worse still, it often COMPLETELY CRASHES Firefox and I have to forcibly KILL the process and restart Firefox, after even ATTEMPTING to use this feature

I have tried it on M1 Macbook Pros, on Ubuntu desktops (24.04 LTS) and also on Android

right now I am typing this in on a Firefox I literally just had to Force Quit and restart on a Mac - build 147.0.2 (aarch64)

Hi there, each time I run firefox, a new firefox icon like the attached picture shows up. Now there are several of them. This starts to crowd the dock, also I'm not sure why they are there because I already have a firefox icon in the main dock. Also they are not windows of a firefox window. Clicking on them does nothing.

Starting with Firefox 147.0, new tabs appear at current tab position when clicking on URL. How can I revert back to new tabs appearing at end tab position when clicking on URL?

Mein Thema betrifft die Änderung der Lesezeichen Verwaltung. Die Lesezeichen bleiben nicht mehr sichtbar sobald man auf eine andere Stelle mit dem Mauszeiger klickt z. B. um einen Tab durch das ziehen mit der Maus in die Lesezeichen ein zu sortieren. Dann funktioniert das scrollen mit der Maus nicht mehr, man muss zwangsweise mit dem Mauszeiger auf einen der Pfeile gehen um das scrollen zu ermöglichen. Wenn man neue Lesezeichen hinzufügen will, oder Lesezeichen in Unterordner öffnen möchte, dann muss mann sämtliche Unterordner umständlich mit dem Mauszeiger aufklappen, wenn man nicht richtig trifft fängt man wieder von vorne an. Wie bekomme ich die vorige Einstellung, und meines erachtens bessere Lesezeichenverwaltung, wieder hin?

是最近才出现这种情况的，应该是某次更新之后出现，但是具体是哪个版本导致的我没有注意到。

问题描述：在任何文本框内输入文本，输入法候选框都会离文本框很远。假设文本框本身就靠下，那么候选框根本就看不见了。

在 Edge 浏览器中没有这个问题。
