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..

Firefox consumes almost 2Gb of RAM with only one tab open. I find this surprising, and it's a major performance issue for me.

Do you have an explanation or solutions to reduce this memory overconsumption?

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?

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.

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 :)

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?

Hello👋 I am using firefox developers edition on build 132.0b2 and my UI is not rendering correctly, the themes work but the objects like the bookmarks toolbar and the refresh button and the home button even some of my extensions is not loading and other things also not loading, but fortunately I know the keyboard shortcuts for these functions and they are working just fine but all the buttons are just not there My device is a Dell Latitude E7450 and it has a normal core I5 5300U so it is not an x86 arm based processor I hope that you find a solution ASAP as I am really struggling with my browser like this and btw I really love your work and the products that you give Thanks for doing the hard work! bye

I am unable to reach Facebook on both Firefox and Waterfox.

Other browsers (Opera, Edge, Chrome) are able to access Facebook.

I can access other Meta-owned sites (Messenger.com, Instagram, Threads) on Firefox and Waterfox.

This issue exists on both my desktop (Windows 10) and laptop (Windows 11).

This issue does not apply to Firefox for iOS or the Facebook app.

All apps and OS's mentioned are up to date.

This has been going on for over a week now.

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?

We still use some Dell 13g servers equipped with idrac 8. When I'm trying to launch the virtual Console the window opens up but nothing shows. This used to work fine in previous versions of Firefox. I can't tell from which version it stopped but it's not long ago. Also idrac 9 console works fine in Firefox When trying to open console idrac 8 in Chrome it works fine Any idea what could be causing it? Any config switch to tweak?

Hi Guys! Huge fan of Firefox since the early 2000s when I first learned about it. Way more secure, efficient, and lighter than any other browser (IE, Chrome, and now Edge). Firefox is my first download on every new device and my go to even on my iPad.

I've been getting this error message lately and I don't know what to make of it. My saved tabs are working normally (email, work, streaming entertainment). This automatically comes out on ever new start / re-start (Firefox is my default) on separate tab but I am not opening any new website. It's been 2-3 days. At first I didn't mind it but its consistently happening and not just a one time thing. I already cleared my cache data. I've also ran a scan and it's come up clean (I have a paid BitDefender subscription). It's also not the local ip of my machine.

So any help would be great as I really don't want to leak any personal data or have any viruses.

Thank you for your time!

When I would mouse-over a thumbnail on the Youtube home page I use to get a video preview with sound and text controls displayed. Video preview and controls are now missing on homepage thumbnails. Is there a way to get preview and controls back ?

I cleared the cache and cookies...no effect. Problem does not exist with Edge browser.

Using Windows 10 / Firefox browser 125.0.3 (64-bit)

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

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

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

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.

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.

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?

When opening a file from another drive, I get an error: Access to the file was denied

I know this can happen on the Snap version, but I have Firefox installed from a deb!
