I've been having issues with the themes on the Firefox Browser. Almost all themes forces dark-mode on the browser. Since update 100 it no longer effects websites, but it still affects the browser (menues etc) despite me having the settings locked on light-mode.

Some videos on YouTube wil not run - shows just that circling arrow !

I'm running a fully updated Windows 10 - F5 don't cure the problem Restart PV, router or modem don't Reset FireFox work but only just after reset - if I try show the same vidoe again - same problem is back ! I have tried running is safe mode - no help ! I've tried to shut down AddBlocker - no help !

It's NOT all videos and not all videos from the same creator !

The problem started 4-5 days ago and is worsening !

What is there to do ?

Since earlier this week my Firefox browser has been turning .jar files from GitLab into .jar.zip files, which prevents them from being used properly until renamed. Attempting to download the same files on Edge or Chrome works correctly, and attempting to download any jar files from other websites (even GitHub) also works correctly. It seems that GitLab is the only website that is affected by this.

Examples of files being affected (they should be downloaded as normal .jar files): 1. https://gitlab.com/Trafalcraft/antiRedstoneClock/uploads/3b3c84814d76810f826c3803eaca1e66/antiRedstoneClock-1.4.1.jar 2. https://gitlab.com/Aristois/ui-installer/-/jobs/2505715157/artifacts/raw/packager/Aristois-Free.jar 3. https://gitlab.com/Aristois/Installer/-/jobs/2495195255/artifacts/raw/packager/free/Installer-2.0.3.jar

I'm using Firefox developer edition (102.0b3), and already tried using private mode, resetting Firefox, and reinstalling. Since I use GitLab as a main source to upload files, many users have also complained the same problem to me, in which all of the users were running Firefox. After they downloaded with a different browser, it worked for them as well.

So I am a web developer, is there a way to change the version of Firefox developer to the latest Firefox version? Because it is currently in beta version.

I am using Firefox developer for web development, and also for testing, and also for day to day web browsing. I just realized that the Firefox developer is a beta version, but our users use the latest version of Firefox. I believe this can be a problem when the development environment is not the same as the user's version.

If I install Firefox's official browser, it will be a waste of storage.

When you add a new bookmark to a folder it's added at the end of the existing list.

Is there a way to make Firefox add it at the top of the list, instead?

I found an old answer, but, sadly, the extension granting my wish is no longer.

Also, I already know about sorting, but it's not what I need, because I'm doing a lot of manual bookmarks reordering and sorting will nullify it.

Thank you :)

Hello Firefox Browser developer. When you go to view the video player does not open in full screen. There is a frame left, right, and bottom. It is equally displayed both on YouTube and, for example. In picture-in-picture mode, everything opens correctly. Cleared the cache. Opens fine for the first time. After the second loading of the browser - the frame is formed again. The problem is clearly on my end. Is it possible to install a third party player? Thank you

A large number of developers prefer to use a vertically-oriented monitor, as it provides a more efficient way to read code. However, as demonstrated in the first screenshot, the Firefox developer tools appear cluttered and disorganized when displayed in this orientation, especially when the three-panel layout is enabled. This makes the user interface difficult to use effectively.

In the second screenshot, even with the right sidebar minimized as much as possible by default, a significant amount of screen real estate remains underutilized, resulting in a subpar user experience. The question arises as to how this issue can be resolved.

If the Firefox development team has not given sufficient attention to optimizing their developer tools for vertical monitor orientations, what is the appropriate way to request that this feature be prioritized in their development roadmap?

Hello, is there a 'Force Dark Theme on pages' feature in any Firefox browser, whether Developer edition or Nightly or ... i'm using Opera just because i can force dark theme on any page while Firefox i trust it and consider it better as browser but i don't use it just for the lack of this feature

Here's how your site looks when i use this feature on Opera, it's attached

And here's how your site looks like on Firefox browser even if i have enabled and selected Dark Theme in your settings, image is attached.

Please add this feature and do not depend on Add-ons or Extension as these community or individual developers' Extensions/Add-ons require full access of browser data, and this is not a secure practice

Hi My government has enabled SafeSearch over our internet. we cant disable or turn it off.

we had a solution to disable it by changing DNS in our browsers to CloudFlare. but unfortunately, it's not working anymore, so the SafeSearch is back online again...

now, how can we disable it?

Since 117(Beta)I have an issue with Firefox refusing to apply the update it downloaded. I've tried searching left and right on the internet for a solution and one does work which is installing the newer version of the browser each time myself. But this is ofcourse not a solution in the long run.

It tries now to apply the update 118b9 to stable version 118 and it did downloaded just fine and asked me if I wanted to close the program to let it update which always worked. I've tried different DNS to see if that could be the problem, tried a clean default profile to see if that helped, I haven't tried uninstalling it and reinstalling it, due to me losing my passwords and what not.

I also tried to run the stable version to see if the issue was still there and it is still there, so me using the beta channel isn't the issue here.

Yesterday when Firefox 111.0 64 bit was installed, updated the unified extension button shows up and it cannot be made to not appear or hidden. I even tried to about:config and change the extensions.unifiedExtensions.enabled from true to false and restarted Firefox yet the extensions button still appears. On older foxfire versions could get rid of it by doing the above and it worked but this new version 111.0 64bit I cannot get rig of the extensions button icon that appears on the end of the tool bar. Please fix it so I don`t have to see this button in the Firefox toolbar at the end of it. I even had a computer online tech try and he says you have it fixed so it cannot be removed. I see others have complained about not being able to remove the button from the tool bar also..

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

A setting I would like to change in both Firefox Beta and Thunderbird Beta is "grayed out" and has a lock next to it preventing change. What configuration file(s) do I look for to find where they have been locked, so I can unlock them and change the setting? Thank you.

I don't know what this is, what it's called, or why the someone in your UI/UX team continues to think that it's a good idea to change the keyboard navigation in the browser with all these new, special, or whatever controls that are ultimately useless.

How do I turn this off?

I have Firefox 107.0b5 (64-bits) Snap for Ubuntu canonical-002 - 1.0 I use Ubuntu Mainline to update to newer kernels. Never had any problem doing that. I am now on 5.19.15. But when I upgrade to kernel 6 (which is now at 6.0.5) Firefox tabs crash. Reloading doesn't help. Each new tab I open gives the same crash message. I have to restart to get Firefox going again. So I removed kernel 6 and reverted back to kernel 5.19 and have no problems any more. But question, what is the problem between kernel 6 and firefox? Does anybody else experience this problem?

I have no other problems with kernel 6 with other programs or hardware or whatever, only firefox tabs crash...

I'm having an issue with a particular text field. When entering any text into said text field, my CPU will shoot to 100% usage on some cores, hang for a bit and then print the text after a few seconds. I have an Intel 13900k @ 5.5ghz.

I can't provide a link to the text box as it's a WordPress CMS on my local machine. This issue does not present itself on the competitor browser.

A few troubleshooting steps I've taken:

• Re-install Firefox
• New profile
• Disable all extensions
• PC safemode + Firefox safe mode
• Tested dev/nightly/stable (I'm using BETA daily)
• Disabled accel

Hopefully I'm able to have an expert look at my profiler to help determine what the issue is. I'm not knowledgeable in this area unfortunately. https://share.firefox.dev/3s60ISV

Thank you.

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.

On my laptop, I run FDE as my daily driver, with the release version to handle my webmail. I also use portable firefox (from portableapps.com) as a browser to use while at work, from a thumb drive. While using that portable verison, I usually just go to google image search, and a work site that would definitely be secure.

My question: I don't like to update the installation on my thumb drive very often, and occasionally work computers are very slow anyways. So if I were to update it no more often than once a month, which version of firefox would be most secure: Release, Beta, or Nightly?

If doing this is just dumb, then which version gets updated less often--it would be Release, correct?
