• I think many people in the comments suffer from some version of curse of knowledge.

    Sure, this feature us quite irrelevant for a power user who is quick to navigate the browser and needs a split second to remember what tab it is simply by reading the header and seeing the icon.

    However, many less proficient people can benefit from this feature. Not once I saw how someone who has 10 tabs open and needs to go to a different webpage, starts meticulously clicking through every single one of them because they have no idea how the page they are looking for is called, they are too overwhelmed by using web as a whole to take notice.

    • Power users love to bash accessibility features like this. Its a classic case of “I don’t need a wheelchair ramp so i dont know why the library added one!”

      Accessibility is way more than screen readers. It’s more than specific disability-minded modes. The web needs to be friendly to everyone, including people who may not know they could benefit from accessibility features. Everyone benefits from this type of work.

      There are definitely some legit feature concerns and priorities being called out here. Mozilla has left a lot to be desired of late on that front. But a power user is more than capable of jumping into settings or about:config to turn things like this off, or finding an extension to get by for now.

      Also the firefox dev team isn’t tiny. This isn’t blocking other work or anything in a substantial way, it’s a fairly isolated piece of UI, and there’s no guarantee that skipping this would change the timeline on anything else.

      • Again, in my opinion you approach the problem like a power user. Using a browser is not a speedrun where every millisecond matters. Here is why I think it provides more comfort to an average user:

        • No need to divert attention and look around the monitor. When you’re not well versed with a mouse, it’s easier to click and look at the same place
        • Nothing distracts you unlike when you click through pages. Imagine going from dark theme page to a light theme page, the entire screen suddenly lights up
        • Depending on the way it is implemented (perhaps by keeping compressed page screenshots?), it might be faster to show a preview than to render the page again on a weak machine
        • I’m not sure how clicking can be considered “power user”… Had I said “just install tree style tabs, it’s much better”, you might’ve had a point, but you’re arguing that clicking is worse than hovering. Really can’t agree with you.

          But hey, I don’t give money to Mozilla and the chance is very low that I ever will, so they can do what they want. If they think this is how they want to spend the 500 million they get from Google, that’s their prerogative.

          • I’m sorry, but did you… read my comment?

            I didn’t say clicking is power user, I said that you assessing features in terms of speed (“Is hovering faster than clicking?”) is a power user approach. It’s deeper than just bare speed and accessibility features are not developed to provide physically faster experience, but one that is more comfortable for some group of users.

            Hovering preview does not even take ability to click through tabs away, but could provide comfort for a user who is not as browser proficient, for the reasons I outlined above.
