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?

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?

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?

Hi,

After the last two updates, the **Pseudo-elements** tab in the Browser Console can no longer be closed once it has been opened, and vice versa.

Please see the video below demonstrating the issue:

Thanks.

Hey guys, am I the only one having trouble finding the right timezone in the widget? I cannot set Indian Time Zone (IST, GMT +5:30, New Delhi, whatever) nor easily find Canadian timezones (i.e., Ottawa).

I know I can put GMT+4 and call it a day but A) I don't want to deal with summertime daylight saving times and B) Funny enough, if I select the GMT+4, clock goes to GMT-4 (and this happens for every other timezone).

In Firefox on my Android phone, when I type about:config in the address bar and press Go, it takes me to a description of that functionality, not the configuration page. I have tried DuckDuckGo, Chrome, and Bing, and they all do the same thing. How can I go to the about:config page?

My Firefox version is 152.0.5 (Build #2016171143). My phone is a Galaxy A32 5G, model SM-A326U, Android version 13, One UI version is 5.1.

6/21/26 This morning I could not open my FireFox browser, unless i created a Profile. I was forced to use the Profiles Wizard to create a Profiles; when i finished all my Bookmarks had disappeared. Which was a great shock, had lots of Bookmarks in Bookmarks Toolbar, Bookmarks Menu, & Other Bookmarks, I need to get those Bookmarks back !! >>More info: I had Hibernated my Dell 15 laptop overnight. This morning when I turned on the laptop, I got the above message that I had to create a Profile, which I did, which made all my bookmarks to DISAPPEAR !! I need them back!

Hi. Recently, not sure of which version as there seems to be a lot of updates :)

I'm currently on 152.0.1 on a Windows 11.

This problem doesn't happen on my Raspberry pi with 152.0 (aarch64) On my Android 13 I have allowed Pop-ups, via about:config, sort of, but there is no option to make Exceptions

So back to Windows 11.

As said I can enter an exception and that works when I load the site I want until I close Fx and I have to do it all again: Enter Domain : Allow : Save etc.

Once, and only once, I closed the [settings] and I'm sure after closing FX and opening it worked fine.

Just closed again and problem has occurred.

The issue arises on my site https://calstock.org.uk which opens a window to a UK weather site, The Met Office. It requires cookies etc. and shows it's own popup.

What I do is open it first in a new window, which is the popup I am referring to, then I load it in an iframe, then I close the popup.

That way the cookie is set by the new window that pops up so there is no query on my main page.

I only have the one extension, uBlock Origin which I have on all devices

Thanks

I wanted to use the new VPN feature and the icon initially showed up in the top right, but it has disappeared and is not present in "customise toolbar" or privacy settings either.
