Mozilla Tests Firefox 'Tab Warming' (bleepingcomputer.com)

Catalin Cimpanu, reporting for BleepingComputer: Mozilla is currently testing a new feature called "Tab Warming" that engineers hope will improve the tab switching process. According to a description of the feature, Tab Warming will watch the user's mouse cursor and start "painting" content inside a tab whenever the user hovers his mouse over one. Firefox will do this on the assumption the user wants to click and switch to view that tab and will want to keep a pre-rendered tab on hand if this occurs. "Those precious milliseconds are used to do the rendering and uploading, so that when the click event finally comes, the [tab] is ready and waiting for you," said Mike Conley, one of the Firefox engineers who worked on this feature.

      No. Page rendering does not run Javascript.

      (Well, currently. There are proposed APIs that could change that, but they aren't implemented in Firefox yet and even if they are, it would be a long time before they're widely used.)

      One example is using a computer whose policies are set to allow temporary installation of third-party JavaScript code into the browser's RAM and disk cache by websites visited by ordinary users but not permanent installation of third-party native code into persistent storage by ordinary users.

    This has nothing to do with tabs loading. It's about rendering what's already loaded.

    Good browser performance already depends on predictive behavior, such as kicking of DNS lookups early when you hover over links. I don't know what you have against predictive behavior, but the alternative is a slower browsing experience.

  24. Re:What is the point, honestly? by roca · · Score: 1

    It all depends on the complexity of the page. It is not difficult to find pages that are slow to render, especially if you are fullscreen on a 4K display, say. Maybe you don't visit such pages, but lots of users do.

  25. Discord closes issues as "WFM in Chrome" by tepples · · Score: 1

    Friends don't let friends use Chrome.

    Uploading custom emoji to Discordapp.com works in Chrome and in Chromium but not in Firefox 57, where clicking the upload button has no effect. It's even worse in Firefox ESR 52 on Debian 9 "Stretch", with many actions lagging and pegging one core of a Core 2 Duo CPU for one or more seconds, sometimes blanking the whole page for a second. Discord staff has a habit of closing issue reports in Firefox to the effect "Works for me in Chrome. Could you try it in Chrome?" Would you recommend stopping using Discord over this incompatibility? If so, then to what text and voice chat platform with built-in support for retrieval and search of older messages and attachments do you recommend that a community using Discord migrate? (IRC lacks voice chat, retrieval and search of older messages, and attachments.)

    Second try: "Jitsi" on Wikipedia. The article states that Jitsi is a native client application, not a server. Therefore, it would need to be used with some sort of server software and a hosting account. It states that Jitsi is available for Linux (by which I assume it means X11/Linux), Android, Windows, and macOS, which would exclude members of our community whose primary device is an iPhone, iPad, or Chromebook. It states that supports IRC and XMPP for text, SIP for voice, and proprietary services of major IM networks (MSNP, OSCAR, and YMSG).
