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 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?

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!

EMAIL: [edited email from community support forum]

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.

Last week I discovered that my emails (yahoo) when clicked on opened a Preview screen next to the email lists. How can the previews be removed and my emails appear across my screen instead of being crammed into a left hand column?

Windows 11 : Fix this ASAP I delete all tabs, close firefox, reopen and I get 5 tabs which seem to be STUCK. I delete 3 of these tabs, go about my work, none of those 3 are open, and I shut everything down. When I reopen Firefox, those 5 "default tabs" (the 3 I don't want have migrated over from I don't know were - both Chrome and Edge open with New Tab.)

I have enough other problems in my life - and done't tell me to create a new profile. At that point I'll kill firefox and end my donations to Mozilla.

I searched how to disable any random new AI features Firefox was about to cram into the browser.

I was served this support page that says I can "Block new and current AI features (single switch)"

Simply, the described feature to disable AI features isn't in the settings. I've look and tried searching for "Block AI enhancements" & "AI controls" but no luck.

Please tell me they haven't given the writing of support pages to some shitty LLM.

I searched, and all the internet results I find tell me to look in the settings:applications:mailto ddlb and select Yahoo. The problem is that it's not there.

There is a "use other" but there's no hint on how I'd tell it to open https://mail.yahoo.com.

How do I get it to open Yahoo mail?

This is on W11.
