This feature is meant to be released in FF 75 next week. However, it's already available in FF 74. So go ahead and enable it.

Here is how you control lazy loading functionality in Firefox:
  1. Load about:config in the browser's address bar.
  2. Confirm that you will be careful if the intermediary warning page is displayed.
  3. Search for dom.image-lazy-loading.enabled.
  4. Toggle the preference so that its value is True (enabled).
You can disable lazy loading at any time by setting the preference to False in about:config. Load the following demo page to check if lazy loading support is working correctly.


See attached after enabling the feature

Another new feature

Firefox 75 Strips https:// and www From Address Bar Results

Like most of the modern browsers, Firefox shows suggestions when you type in the address bar. Those suggestions are based on your recent browsing history, include bookmarks, and may include search engine suggestions. The upcoming version 75 of Firefox strips the https:// and www portions from the suggestion URL.

When explaining the change, Mozilla noted that modern browsers are already hiding these parts. The company must be referring to Google Chrome, which is a product known for introducing such changes. So, starting in Firefox 75, the browser will replicate this behavior, and hide https:// and www parts from the suggestion URL.

The current version of Firefox shows suggestions as follows:

Firefox Address Bar Suggestions With HTTPS


As you can see in the screenshot above, both https:// and www are visible next to the suggestion title.

Here is how the same looks in Firefox 75, which is in Nightly as of now.

Firefox Address Bar Suggestions Without HTTPS


While the HTTPS portion is hidden, Firefox 75 shows the protocol if the classic plain HTTP is in the URL.

As of this writing Firefox 75 'Nightly' comes with a special about:config option to disable the new behavior.

Disable New Behavior
  1. Open Firefox.
  2. In a new tab, type about:config in the address bar.
  3. Click I accept the risk.
    Firefox About:config Warning
  4. In the search box, type or copy-paste the line browser.urlbar.trimURLs.
    Firefox Browser.urlbar.trimURLs
  5. Double-click on the value name in the search result to toggle its value from true to false.
    Firefox Restore Classic Address Bar Suggestions
You are done. You can reset the value at any time later to restore the new behavior.

Personally, I find this change unpleasant. I am familiar with a couple of sites which return differently formatted pages for www and non-www URLs. Hiding anything from the URL is always a bad idea, because it makes it harder to understand what is going on in case you see something that you didn't expect to see on a web page.
