Viewport in the devtools going out of bounds when resizing the viewport

Hello everyone, I’m a fan of Firefox due to its efficient handling of webpage caching and memory management. However, I often find myself switching back to the Chromium-based Edge browser due to one specific feature in its DevTools. In Edge, when I resize the viewport, it stops at a certain limit. If I want to resize it further, I can zoom out and then continue resizing. I find this feature very useful. Is there a way to have similar functionality in Firefox? I’m currently using the Firefox Developer Edition.

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?

A few days ago I was downloading a ZIP file and was warned that "This file contains a virus or malware". Fine, thank you for telling me but now how do I seeing the same warning every time I start Firefox? The file in question does not exist on my computer so far as I can tell and I did a thorough search through 3.5tB of storage on the machine to make sure. How do I stop this warning?

I cannot watch a video on youtube when it is in the process of being live streamed. I remember a time when I was able to, years ago, but I can't any longer. I'm not sure what has changed. I found an article that says to install the optional update called "Windows Media Pack" in apps and features, but no app with that name exists. It was only a year old solution, so I'm unsure of what changed so significantly. I just installed another optional windows update, and also updated the browser, but still doesn't work.

Hello,

Whenever I use Firefox, I end up seeing popups (necessary for school) and would like to show them as tabs so I can merge them into other windows. I have tried the solutions given in: https://support.mozilla.org/en-US/questions/1080255 and nothing seemed to work. Is there another way to make sure that popup windows cannot hide the toolbar and show tabs?

Hi,

I've been encountering a strange issue where colors (especially whites) in the video player are super washed out. This only happens when HDR is turned on in windows, and only happens in my Firefox Developer Edition installation (normal firefox works fine). It also doesn't show up in any windows screenshots - the colors revert to normal when I'm in the screenshot GUI. I've attached photos below of a youtube video, the left is firefox DE and right is normal firefox, both in and out of the screenshot GUI so you can see the difference.

I'm on Windows 11, and I'm not sure what caused the issue. I've tried both refreshing and reinstalling firefox DE to no avail. Pretty stumped on this one, and would appreciate any help!

I first realized an issue with downloading PDFs through the Firefox viewer - I cannot. The download button does nothing, there is no prompt, no popup, and no file downloaded. I have also tried to print to pdf, that also seems to fail.

Today I realized I also cannot attach any files to an email through Gmail in Firefox, which is now leading me to believe that the software is unable to interface with my files at all.

Things I've tried include: - Turning off popup blocker - Refreshing Firefox in the ->Help->More Troubleshooting Information Menu - Starting Firefox in safe mode - Reinstalling through snap

The only way I can currently download files is through wget, and the only way I can send attachments is by installing Google Chrome, which is kind of a last resort for me.

I am running Ubuntu 22.04, this is on Firefox 106.0, though it didn't work last update either.

Thanks for any help


Edit: I have been googling for answers but after posting this question a similar thread popped up, the solution is to install the following packages:

xdg-desktop-portal xdg-desktop-portal-gtk

Every time I go to Fox News, the video at the top of the page drops to the lower right-hand corner. It's an annoyance I've been searching for a way to eliminate. I have pop-ups blocked in preferences and I have a couple of different pop-up blockers, but nothing seems to work. I'm currently using Firefox 114b.09 on a Mac Desktop.

Hello.

It seems I get a problem or two almost always with a new update lately. I have been using an userChrome.css to reduce the width of sidebar but the latest version 107.0 now ignores it and have a wide width even at the narrowest. Mine currently is set as, "#sidebar {min-width:30px !important; max-width:none !important;}" This no longer works. Your support much appreciated.

Regards,

In the new version of the Developer Edition the options "close tabs to the right" and "close other tabs" are in a sub-menu named "Close Multiple Tabs" inside the context menu. Is there's a way to change this so that they will appear directly in the main context menu? I use "close tabs to the right" often and I find this very annoying.

Is there any way I can completely disable horizontal scrolling? I'm using a laptop with a trackpoint (lenovo x230, Windows 10) and it's not terribly accurate, which means scrolling whilst a youtube video is going often makes it track backwards or forwards, and another website I use uses a horizontal click to send me to the next page, which sucks. I would prefer to just be able to disable it entirely. Thanks!

I swear to god I used to have it disabled, just need to work out how again.

YouTube Video GPU Decoding only works in Troubleshooting Mode

I recently upgraded graphics cards from an Nvidia GTX 1080 to an AMD 6900XT. Since then I noticed video stuttering on YouTube while playing 4k videos, especially noticeable at 4k/60FPS (example video ). Prior to the upgrade, I was not experiencing issues.

I monitored task manager as the video was playing to see CPU usage, which was sitting at 25% (4 core 8 thread CPU). GPU usage was fluctuating from 1-3%.

I tried resetting all the changed configuration options in about:config, removing all add-ons, "Refreshing" Firefox, and ultimately uninstalling and reinstalling. Nothing has worked so far except for "Troubleshooting mode" in about:support. In that mode, I experience no stuttering and GPU usage rises to 25-35% with the video playing, even before I reinstalled.

This most likely isn't a networking issue as the "Stats for nerds" option on the YouTube video shows I have 10-20s of buffer while the video is still stuttering.

I would like to find out what's different about Troubleshooting Mode that is not giving me the same problem while in "Normal Mode". Any advice?

I had set up a userContent.css file in the past to pull up and fetch an image on my computer to display as a background on the homepage. It worked and did it's job until recently, when I had recently relocated a lot of my files around on my computer. I have redirected everything to where I want it to look, including the userContent.css file to the new location for the image I want as the background. Firefox loads the .css file correctly, and recognizes the file existing, but it won't load the image itself for some odd reason. It states it "may not load or link the file" because of a security error, and thus, can't load the image. I never had to deal with this before. How can I get Firefox to be able to load my image like I want it to? I have screenshots that I can provide, but this site doesn't want to upload them at the moment.

When you open a link from the sidebar while holding ctrl, firefox opens it in a new tab and switches to it immediately; whereas when you click a link from a webpage with ctrl, it does not switch to the new tab (unless you hold shift as well, or check "When you open a link, image or media in a new tab, switch to it immediately" in settings > general > tabs). I would like if firefox does not automatically switch to opened links from the sidebar (history, bookmark, etc.), when I open them with ctrl? (I know I can hold shift to do that, but I was wondering if there might be a preference in about:config to change the reverse this behaviour for sidebars)


Thanks, Ibr.
