in the new nova settings ui the selected category is highlighted in light purple. not a fan. how do i change it. don't mind collateral damage as I'm not of fan of this color

I have a list of websites that I keep in the cookies exceptions list so I remained logged in. But I noticed the list is blank in a few recent Firefox versions, even though the sites still retain the cookies. That means I cannot edit the entries or even see them.

I received an email stating the following: "Firefox now has a built-in ad blocker.... Turn it on under Settings > Browsing." There is no "Browsing" in my Settings.

As the title suggests, here’s something that caught my attention in the new settings screen. Specify directly from about:config ↓ Change `network.trr.mode`

Value Behavior 0 Do not use DoH 2 TRR-first 3 TRR-only 5 User explicitly disables DoH

Does this provide the same effect as the “Strong Protection” and “Maximum Protection” options that were available in the previous settings screen? I would appreciate your response.

About two months ago, after various Windows and Firefox updates, I can no longer make Firefox the default browser. In Windows Default Apps the only option for FF is to make it the default program for Adobe Acrobat Document. Choosing Make FF Default through the browser does not work either. Additionally, I’ tried numerous suggestions, using AI help offered by both FF and Chrome, without success.

The OS is not allowing me to make Firefox the default browser. Is there any way around this?

Any suggestions?

Firefox: 155.0.1 (64-bit) Windows 11 Pro Version: 25H2 OS build: 26200.9278

Thanks

I'd like to try out the built-in VPN, but can't find it. I've seen many older posts about this, but nothing recent. It's now August of 2026.

I'm using Firefox 154.0.1 on Android 16. I'm in the United States.

I'm logged into my browser with my Firefox account. I know it's working as I can open browser tabs between my mobile device and other devices using my account.

I'm not seeing the built-in VPN feature.

"VPN" does not appear in Settings as described in https://support.mozilla.org/en-US/kb/mobile-android-vpn

By comparison, attached is a screenshot of what I have in Settings > Privacy and Security.

Any guidance?

I tested the security of my VPN and found firefox browser was allowing the WebRTC for video/audio which it is built into the browser is reporting my IP address. All I need to do is open about:config then go to media.peerconnection.enabled and change it from true to FALSE

Now after about:config is typed in the address bar the page stops loading or to say the page will not load. I am doing this on Android Firefoxs home page, beside all the different browsers you can choose. What's up with all that stuff, Please help me plug this leak! Helped me open the config program. Thank you, Mudiver

I have Firefox 15.3.0.1 on two computers. One one, when I go to about:config, there is a search bar with an option to "Show only modified preferences." On the other computer this search bar is missing. How can I make it display on the second computer?

The website mozilla.github.io/policy-templates makes mention of the FTPProxy option that can be set for Firefox. However the admx file under github.com/mozilla/policy-templates/blob/master/windows/firefox.admx makes no mention of that setting. Is the documentation in the admx file incomplete or am I missing something?

Sirs. We cannot download the ¨Clear Browsing Data by Armin Sebastian.¨ It is a Firefox Recommended Add-On. We are getting error messages. One common one is... ¨...Firefox cannot modify the needed file.¨ I am also unable to download the Official ProtonVPN extension as well, with the Error being...¨Firefox prevented this site from asking you to download software on this computer.¨

We have not found any solutions in your ¨Newest¨ Settings ¨Bloatware.¨ Please give a step-by-step guide to resolve these two problems. Sincerely, JTHML Creator, IllustratorZ, and OwnerZ ( [redacted email] ) P.S. Where have all the Sporks Gone?
