在我看来，与其他浏览器相比， Mozilla Firefox Quantum^{(Mozilla Firefox Quantum)}的性能更好，而且似乎越来越强大。不过，与所有应用程序一样，它会随着时间的推移而变慢。为了在这方面进行改进，Firefox正在考虑实施一项新功能 - Tab Warming。该功能旨在使用户的标签切换过程更快，以帮助他们在浏览会话期间节省一些额外的时间。

Firefox 中的标签预热功能

Mozilla开发人员Mike Conley在其个人博客上的一篇文章中透露了Firefox Nightly中的^{(Firefox Nightly)}Tab Warming功能的详细信息。确切的定义是，它是一个先发制人地为选项卡渲染图层的过程，并在浏览器非常确定您可能切换到该选项卡时先发制人地将它们上传到合成器。

早些时候，浏览器采用了一些不同的方法。该机制运行良好，但开发团队认为他们可以让它稍微好一点。

标签^(Tab)变暖目前通过首选项控制。在Firefox^(Firefox)浏览器中打开一个新选项卡，输入about:config并点击“Enter”。

然后，当“关于：配置”页面加载时，查找以下条目 -

browser.tabs.remote.warmup.enabled

目前默认关闭。因此，您需要双击该选项并将其状态切换为True。这将启用“标签加热”功能。

到目前为止，浏览器只是检测你是否用鼠标悬停在标签上，以预测你可能会选择它，但肯定有更多机会根据其他用户的行为引入变暖。

Mozilla解释^{(explains it)}如下：

With Tab Warming enabled, when you hover over the tab with your mouse cursor, the rendering of that sophisticated SVG will occur while your finger is still on its way to click on the mouse button to actually choose the tab.

Firefox声称它将获得加载网页所需的时间，因为当您在单击之前将光标移动到该选项卡时，选项^{(Tab Warming)}卡预热功能会立即在后台加载页面。

Make tab switch faster in Firefox browser with Tab Warming feature

Mozilla Firefox Quantum рerforms better in comparison to other browsers in my opinion and seems to be going ѕtrong. Like all apps though, it can slow down over time. To improve on this front, Firefox is contemplating to implement a new feature – Tab Warming. The feature intends to make the tab switching process faster for the users to help them save some extra seconds during their browsing sessions.

Tab Warming feature in Firefox

The details of the Tab Warming feature in Firefox Nightly were revealed by Mozilla developer Mike Conley in a post on his personal blog. The precise definition says it’s a process of pre-emptively rendering the layers for a tab, and pre-emptively uploading them to the compositor when the browser is pretty sure you’re likely to switch to that tab.

Earlier, the browser followed somewhat different approach. The mechanism worked pretty well but the team of developers thought they could make it slightly better.

Tab warming is currently controlled via Preferences. Open a new tab in Firefox browser, type about:config and hit ‘Enter’.

Then, when the ‘About:Config’ page loads, look for the following entry-

browser.tabs.remote.warmup.enabled

This is currently off by default. So, you’ll need to double-click the option and toggle its status to True. This will enable the ‘Tab Warming’ feature.

As of now, the browser simply detects whether you’re hovering a tab with a mouse to predict that you’re likely going to choose that, but there are certainly more opportunities to introduce warming based on the behavior of other users.

Mozilla explains it as follows:

With Tab Warming enabled, when you hover over the tab with your mouse cursor, the rendering of that sophisticated SVG will occur while your finger is still on its way to click on the mouse button to actually choose the tab.

Firefox claims it will gain the time it takes to load up a webpage, as Tab Warming feature begins to load the page instantly in the background the moment you move the cursor to that tab before clicking on it.
