&lt;/div&gt;
&lt;h3 style="font-size: 24px; margin-bottom: 0; padding-left: 24px; padding-right: 24px;"&gt;Firefox is cooking again&lt;/h3&gt;
&lt;p style="font-family: Outfit, sans-serif; font-size: 17px; line-height: 1.5; padding-left: 24px; padding-right: 24px;"&gt;Mozilla shipped &lt;a href="https://c5e21242.click.convertkit-mail.com/gku3k3q5wwh5hlgqv3vcrh8wx2699imh2w30/qvh8h8udeek4lzul/aHR0cHM6Ly93d3cuZmlyZWZveC5jb20vZW4tVVMvZmlyZWZveC8xNDcuMC9yZWxlYXNlbm90ZXMv" style="color: #12b5e5; font-weight: 600; text-decoration: underline;" url-id="1828032134"&gt;Firefox 147&lt;/a&gt; two weeks ago, and it’s easily one of their biggest web-platform releases in years.&lt;/p&gt;
&lt;p style="font-family: Outfit, sans-serif; font-size: 17px; line-height: 1.5; padding-left: 24px; padding-right: 24px;"&gt;It’s particularly refreshing after last month, when Mozilla’s CEO surprised everyone by &lt;a href="https://c5e21242.click.convertkit-mail.com/gku3k3q5wwh5hlgqv3vcrh8wx2699imh2w30/g3hnhwumggql09ur/aHR0cHM6Ly9ibG9nLm1vemlsbGEub3JnL2VuL21vemlsbGEvbGVhZGVyc2hpcC9tb3ppbGxhcy1uZXh0LWNoYXB0ZXItYW50aG9ueS1lbnpvci1kZW1lby1uZXctY2VvLw==" style="color: #12b5e5; font-weight: 600; text-decoration: underline;" url-id="1828032135"&gt;announcing&lt;/a&gt; his &lt;del&gt;threat&lt;/del&gt; &lt;em&gt;vision&lt;/em&gt; for Firefox to evolve into “a modern AI browser that will support a portfolio of new and safe software additions.”&lt;/p&gt;
&lt;p style="font-family: Outfit, sans-serif; font-size: 17px; line-height: 1.5; padding-left: 24px; padding-right: 24px;"&gt;Turns out approximately zero Firefox users asked for this. But thankfully, old-fashioned cyberbullying still works in our modern times. So after taking &lt;em&gt;a lot&lt;/em&gt; of flak from their most passionate users, Firefox backtracked and &lt;a href="https://c5e21242.click.convertkit-mail.com/gku3k3q5wwh5hlgqv3vcrh8wx2699imh2w30/9qhzhdud4456erf9/aHR0cHM6Ly9tYXN0b2Rvbi5zb2NpYWwvQGZpcmVmb3h3ZWJkZXZzLzExNTc0MDUwMDM3MzY3Nzc4Mg==" style="color: #12b5e5; font-weight: 600; text-decoration: underline;" url-id="1828032136"&gt;promised&lt;/a&gt; to build an “AI kill switch” that would let users disable all AI features entirely.&lt;/p&gt;
&lt;p style="font-family: Outfit, sans-serif; font-size: 17px; line-height: 1.5; padding-left: 24px; padding-right: 24px;"&gt;And one month later, they shipped Firefox 147 with a bunch of long-awaited platform features and zero mention of AI. Coincidence? You tell me. Here are the three biggest upgrades:&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;p style="font-family: Outfit, sans-serif; font-size: 17px; line-height: 1.5;"&gt;&lt;strong style="font-weight: 600;"&gt;Navigation API&lt;/strong&gt; – A modern successor to the &lt;code style="font-size: 14px;"&gt;history&lt;/code&gt; API that lets apps initiate, intercept, and manage navigations without relying on fragile &lt;code style="font-size: 14px;"&gt;popstate&lt;/code&gt; hacks. Great news for frameworks, routers, and SPAs.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p style="font-family: Outfit, sans-serif; font-size: 17px; line-height: 1.5;"&gt;&lt;strong style="font-weight: 600;"&gt;CSS Anchor Positioning&lt;/strong&gt; – This means all modern browsers now support tethering elements like tooltips, popovers, and menus to anchor elements, using only CSS.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p style="font-family: Outfit, sans-serif; font-size: 17px; line-height: 1.5;"&gt;&lt;strong style="font-weight: 600;"&gt;View Transition upgrades&lt;/strong&gt; – New selectors like &lt;code style="font-size: 14px;"&gt;:active-view-transition-type&lt;/code&gt;, better devtools visibility, and APIs to introspect active transitions. It’s another big step towards smooth, app-like UX on the web without relying on framework magic.&lt;/p&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;p style="font-family: Outfit, sans-serif; font-size: 17px; line-height: 1.5; padding-left: 24px; padding-right: 24px;"&gt;&lt;strong style="font-weight: 600;"&gt;Bottom Line:&lt;/strong&gt; I know that most of this work was underway long before the “AI browser” fallout, but it’s nice to at least pretend that a company listened to its users, slowed down the AI hype train, and shipped a bunch of features that developers actually want.&lt;/p&gt;
&lt;p style="font-family: Outfit, sans-serif; font-size: 17px; line-height: 1.5; padding-left: 24px; padding-right: 24px;"&gt;Hopefully other software companies follow Firefox’s lead.&lt;/p&gt;

&lt;p style="font-family: Outfit, sans-serif; font-size: 17px; line-height: 1.5; padding-left: 24px; padding-right: 24px;"&gt;In JavaScript, if you want to use a variable as the key of an object, you need to use bracket notation instead of dot notation.&lt;/p&gt;
