Firefox Settings

Here are settings and extensions that I use in Firefox.

about:preferences

Do Not Track: Always
Enable HTTPS-Only Mode in all windows
Enable DNS over HTTPS
Address Bar -- Firefox Suggest > Shortcuts: Uncheck

about:config

browser.tabs.closeWindowWithLastTab: false
browser.tabs.insertRelatedAfterCurrent: false
browser.search.openintab: true
browser.tabs.loadBookmarksInTabs: true
browser.enable_automatic_image_resizing: false

When you load a large image in a new tab, Firefox will resize the image to fit the window.

This preference allows you to load or refresh a stand-alone image without having to click to zoom.

Extensions

OptMeowt

Firefox Multi-Account Containers

NoScript

Swift Selection Search

Greasemonkey

Privacy Badger

DuckDuckGo Privacy Essentials

Template Profile

I create many Firefox profiles. And, while it is nice to have these steps enumerated, the process of creating a Firefox profile is not as easy as it could be.

To that end, I have a new process where I create a new Firefox profile, copy my default settings from a template, and then customize the new profile. I am following the instructions for backing up and restoring Firefox profiles. The instructions are linked below. In this way, I have most of the settings saved in the template. And then all I have to do for the new profile is add a home page and log in. I no longer have to go over the list above and change every setting.

Make sure to check your search engine after customizing. I've found Firefox likes to reset the search to Google.

Bookmarklets

A bookmarklet is a small piece of JavaScript that can be saved in the Address field of a bookmark. Then, when the bookmark is clicked, the JavaScript is executed.

The bookmarklets below generate a formatted link for the current page. Click on the bookmarklet and copy the link from the prompt.

These bookmarklets don't work on every Web site. I believe the issue is some sites restrict the JavaScript: URI via their Content Security Policy.

Gemini Link Bookmarklet

javascript:(function(){
  var myText = '=> ' + document.URL + '    ' + document.title;
  prompt("Gemini Link", myText); 
})();

Markdown Link Bookmarklet

javascript:(function(){
  var title = document.title; 
  var url = document.URL; 
  title = title.replace(/\u005b/g, "\\[");
  title = title.replace(/\u005d/g, "\\]");
  var myLink = "[" + title + "](" + url + ")"; 
  prompt("Markdown Link", myLink);
})();
