Firefox: disable autofill in forms

How to disable autofill (or autocompletion) in Firefox forms

For some reason they don't make this so straightforward any more.

Just go to about:config and set

browser.formfill.enable = false
browser.formfill.expire_days = 1
services.sync.prefs.sync.browser.formfill.enable = false

There's a suggestion that setting browser.formfill.expre_days to 0 is more secure for expiring existing saved data, however 0 often means never expire. Without looking at the code, I'm just going to err on the (to my mind) safer bet of setting it at 1.

Firefox: Vertical tabs are here!

With the demise of Arc Browser, fear not, vertical tabs are finally here in Firefox (with a little help).

It's built and deployed, just not yet set loose on the masses. But all it needs is a little tweak.

Go to about:config
set sidebar.verticalTabs to true
questionable: sometimes setting sidebar.revamp to true is also necessary, but in my case it was automatically set.

Voilà! Vertical tabs

Resize the tab area with mouse to see tab names, adjust to taste.

Firefox: How to add a search engine manually

Sat, 01 Mar 2025 00:00:00 +0000

Mostly you can add to your list of search engines just right-clicking. Why bother? Well, maybe you have a niche default search preference, but also it's extraordinarily handy for setting up shortcuts IMHO.

Example: add YouTube to Firefox as a search engine

Go to YouTube
Right-click the URL

Right-click menu on YouTube URL in Firefox

Now you'll find YouTube in Firefox settings:

YouTube search engine in Firefox Search settings

If you give it keyworkd y for example, now when you type y laika party in the search bar, you'll get the YouTube search results for "laika party".
