The foundation Mozilla is currently testing a new feature called “Tab Warming” or in Greek Heated Tabs. The Greek name it might sound funny, but the engineers developing the technology hope it will improve the process of switching tabs.
According to a description of the feature, the upcoming Tab Warming feature will track your mouse cursor and start "painting" the content within a tab whenever your mouse hovers over one.
Ο Firefox with the specific feature it will recognize when the user wants to do click to see a tab and will try to initialize or preheat it against Mozilla engineers.
“These precious milliseconds are used for the best upload performance, so when the click event eventually comes, the tab will be ready and waiting for you," said Mike Conley, one of the Firefox engineers working on the feature.
The Tab Warming developed by Mozilla, should not be confused with loading tabs or preloading tabs. The tab should already be loaded in the program browsing (probably they are directed at me as the open tabs sometimes exceed 100).
The function refers to the “painting,” tab, which is the process of displaying the contents of a σελίδαs within a tab.
Conley said that although this feature is being prepared to improve Firefox's experience in switching between already open tabs, which in some cases may display white pages, the actual gain will be a few milliseconds.
"For many cases, I really think the card warm-up will not be very noticeable," Conley said.
"In my experience, we are now able to run most sites fast enough that the difference is negligible."
“However, there are some sites that can't deliver and display their layers quickly. These are the pages that I think will help Tab Warming, Conley said.
The Mozilla engineer was referring to websites displaying CSS animations and may take some time to display a functional page. The same can happen on pages that display multiple images that may take time to calculate before they appear.
We'll see this feature in upcoming versions of Firefox, as it is currently experimental and only deployed on Firefox Nightly.
It is also not enabled by default. Those of you who want to try it, except after installing Firefox Nightly, you will need to enable it manually.
This is done by about: config and setting:
"browser.tabs.remote.warmup.enabled”. With a double click, set the value to true and you're good to go.
To not look for:
About: config? filter = browser.tabs.remote.warmup.enabled
