I use EndeavourOS and have U-Phoria UMC202HD audio interface connected to my PC. I know that the interface doesn't have mono/stereo switch and the only device connected to it is my microphone (connected to Input 1 socket). The problem is Firefox is receiving sound on left channel (Input 1 socket) and then it sends it without any modifications further, so f.e during meeting on Jitsi people hear me really quiet and only from one channel. Trying online mictests also ends with recorded sound being played only from left channel. I tried chromium based browsers and everything works fine there. Is there any solution for this?

Firefuxxed was refusing to open new tabs so I shut it down and restarted it (always fixes it) and all my pinned and open tabs were gone with no way to recover them, it took me half an hour to manually restore the pinned ones one by one but not all of them as I cannot remember all of them let alone all the open tabs I had (hours of research gone down the toilet).

There should be a way to backup and restore pinned and open tabs so this doesn't happen, the history option does nothing.

OS: Linux Mint 22 fresh install from a week ago Previous version of Firefuxxed updated after this shamossel.

This is a very minor issue. I don't know if this is a bug or unintended behavior, but it's my one gripe with tab groups.

Happens When:

• in a tab group, AND
• the current active tab is the rightmost tab of that group

Behavior: Then when opening a new tab, it puts the tab into the group to the right, or if the group is the rightmost group, it doesn't put it into a group at all.

This behavior is frustrating, because if the tab group to the right is closed, it makes navigating to—and from—the newly opened tab very frustrating, as the group it exists in can be collapsed.

I am now receiving this notice for more and more commonly accessed websites. I get the message if I have https only selected or not selected. Currently receiving for Lowes, Home Depot, American Airlines and more. I can go to a Firefox 135.0.1 browser on a separate desktop accessing the internet through the same router and do not have issues. I suspect I have been upgraded by Mozilla into a less functional browser version for whatever reason that Mozilla does this.

I didn't use my PC for 2 weeks, they worked fine before but now x/twitter notifications stopped working and I can't enable them. They still work on other websites like discord. console output: https://paste.debian.net/plainh/a634d235

I made a copy of the profile, in the copy I disabled extensions (Troubleshoot Mode), removed prefs.js and user.js, removed x.com site data, disabled Enhanced Tracking Protection, still can't enable notifications log: https://paste.debian.net/plain/1391196

making completely new profile does let me enable notifications in it but I'd like to figure out how to get them working back again in my original main profile log in fresh new profile: https://paste.debian.net/plainh/a73668f3

All of a sudden Firefox started to use alt+number (e.g. alt+3) to switch to that tab (i.e. tab 3 in my example).

Why? How do I disable this? It prevents me from typing any of the special characters that are located on alt + any number key. E.g. I can type the at-sign, not the dollar, or any such character which requires the alt-modifier and a number.

I don't know if this ever worked in FF, since I've been on Chrome a while. I tried canvas.toBlob() in FF without a solution.

The behavior is the same whether the served image is jpg or webp. A Servlet delivers the image data, here in webp:

          response.setHeader("Content-Type", "image/webp");

On page, I use a canvas thus => see '// FIREFOX'

     var canvas = document.createElement( 'canvas' );
     canvas.width = width;
     canvas.height = avail_height;
     var context = canvas.getContext( '2d' );
     context.drawImage( imgsrc, 0, 0, width, avail_height);
     context.lineWidth = 150;

     // FIREFOX: canvas.toDataURL('image/jpeg')=black, png,webp,default=transparent
     img.src = canvas.toDataURL('image/jpeg');

     img.onmousedown = disableDragging; // for FF
     img.style.opacity = "1.0";
     console.log('setImg ok');

Inspecting a black jpeg:

        data:image/jpeg;base64,...

Thanks!

Browser has been buggy lately. When I want to close a tab, a new window opens and the tab I wanted to close appears in this window. Please fix the error!

I'm writing here because I don't know where else to write. If you can, please pass it on to the developers

I am experiencing an issue with vertical tabs that appears once more than 3 tabs are open. This is happening on the .deb installation of Firefox (version 136.0) across 3 different devices, with different profiles, also when all extensions are disabled. The issue seems to be specific with vertical tabs, as it does not happen with the classical horizontal ones.

The issue: In the vertical tabs sidebar I can move any tab up to any desired position. However, when moving a tab down, the next 2 positions are inaccessible (unless the lowest position in the sidebar is reached in less than 3 steps), it can only be moved to any position lower than that.

Illustration: Assume you had 5 tabs open, named A, B, C, D, and E. And let's assume you wanted to move tab B one position down to be situated between C and D. What I currently have to do to achieve that, is to move B below E (3 positions down: A, C, D, E, B), before I can move back up above D (2 positions up: A, C, B, D, E).

Seeing how tedious that is, I can only assume that it is unintended behavior caused either by a bug, or a setting (if so, which parameter in about:config should I look for?).

Any suggestions to resolve this are appreciated.

I have the issue that despite hardware acceleration is working Firefox causes a high cpu usage which leads to the CPU is constantly boosting to high frequencies and this to higher power consumption. In about:processes of Firefox I can see that the main process is at CPU usage around 150% or higher and tabs (8 in total usually) that contain live stream video spiking up to 50%. nvtop, intel_gpu_top and LACT all indicate that hardware acceleration is working. btop shows even a CPU usage of the Firefox main process over 175%. The overall CPU usage of the system is at 60%. I couldn’t find any helpful information so far in the internet. Maybe here we can get trace of the cause. The reason is I want to bring down the power consumption. Question is is there an issue or I am facing a (hardware) limitation.

I did two traces with Firefox profiler.

Here and here are the results.

I can provide additional information and logs if needed.

Sync works fine between my Android phone and my devices, in that I can see open tabs on the phone from both devices. But what does not work is sync between the laptop and desktop. They are both listed as connected devices along with the phone, both are signed in, both synch with the phone but neither will sync with the other, so I can't see the open tabs on either device. Is this an issue or is it by design? Thank you.

My Firefox profile just doesn't work anymore, it can't load any pages up, my addons aren't loading up (images not appearing), default themes, etc. but I still have my history and bookmarks and it knows what addons I have, I think the issue is just the profile is just not connecting to the internet. FYI the other default profile works.

I'm trying to access a local web application (GoPhish) running at https://127.0.0.1:3333 on Kali Linux. Firefox is showing a security warning and won't let me access the site . How can l bypass this warning safely, or add an exception for local addresses with self-singned certificates?
