MacOS: If not already running, Firefox does not load requested URL on launch MacOS 26.5.2, Firefox 152.0.4

How to reproduce: 1) Set Firefox as the default browser 2) Completely quit Firefox 3) Open a URL (e.g. open Spotlight, type a query, select "Search the web", or any of the many other ways) 4) Observe Firefox opens but does not open a tab with the externally requested URL

This used to work fine. It still works on Windows. Reproduced on two different Macs. If Firefox is already running, it works as expected.

Windows 10, Firefox 131, Thunderbird 91.13 I set Firefox as default browser - I can't open links from Thunderbird in Firefox. I set Chrome as default browser - I can open links from Thundebird in Chrome. How can I fix or debug this?

So whenever I click on new tabs, it always leads to a redirect notice asking me to confirm if I want to open those tabs.

I want it so that I don't get these notices, but the links I click on just open automatically. I have tried the following settings in about:config based on a few threads online:

accessibility.blockautorefresh

network.http.redirection-limit

A few other settings to that I have turned on and off but no difference.

A lot of the websites are also confusing because they seem to want to turn redirects ON rather than off, so potentially I am struggling to follow the correct information.

Any help appreciated.

On every browser I've ever used for all of my internet using life, including THIS browser, when you hover your cursor over a link, a cartoony hand appears and the link URL appears at the bottom. Very recently, I write on 7/27/26, this no longer works on Firefox. WTF?

I used to be able to clink on an image link prior to a Firefox update (I don't know which one) to go to that site. Firefox gives me that it cannot find the server. What can I do to correct this problem?

Since the latest beta update, Beta, v. 154.0b5 (64-bit) I cannot select or highlight text in either the address or search bars. Is this a known problem? (See red arrows in screenshot)

Google browser keeps popping up in my browserwhen Firefox is my default browser in my setting and downloaded & installed from my Google playstore. I don't like Google and what it does but I feel trapped because I have so much important data on their Gmail and other Google apps. I am a senior with traumatic brain injury and have no tech knowledge or experience to have other options.

How do I get the 'open in new tab' option back when I use the right button on my mouse. It does not appear on the menu when I right click? This is a change overnight and I have not altered any settings.

Hello Mozilla, FireFox in my default browser, but since you last update to 150.0, now my outlook won't open the hyper links from e-mail with them. It worked just fine between the two before. Now I get a message " this operation has been cancelled due to restrictions in effect on this compute. Please contact your system administrator." I am the administrator! anybody else report this issue since? I've tried all the internet advised fixes of changing the regedit registers from FIREFOXhtml to just htmlfile, but no joy. Any help with this would be greatly appreciated. Kind Regards Edward England, UK

Currently when I click a link in and email, it always opens in Microsoft Edge even though my computer has Firefox as default browser. Is there another setting I'm missing?

General Default browser

Firefox is your default browser. Good choice.

Investigate why Firefox is not opening links from third-party apps. Firefox is my default web browser but this issue is making my experience difficult as I have to copy the link and use a different browser.
