The More Popular the Browser, the Slower It Is

While it should not be surprising to anyone that IE slugs at the last place, the gap between Firefox and Chrome, is.

    I'm really surprised at the number of people who use noscript. Adblock is not surprising, since sites often fail to follow the common sense rules of advertising. But what is up with noscript? I've pretty much never had javascript freeze the page or anything of the sort. (On the other hand I don't use dialup). The security implications of letting javascript run are actually pretty minimal.

    Now, as for flash adverts, I've never had an issue with the download size, although sound is an issue.

    As for advertisements, if they fellow the following rules I don't mind them.

    Rule 1: The advertisment must be on the relevant page.
    Rule 2: The advertisement must remain entirely within a rectangle on the page that does not overlap the page content.
    Rule 3: The advertisements must be reasonably sized.
    Rule 4: While animation is permissible, rapid flickering of any sort is not permissible, nor is automatically playing video. Playing video as a result of clicking on the advertisement is acceptable, as is a limited amount of automatic pre-buffering.
    Rule 5: Sound is not permissible.
    Rule 6: If a user chooses to interact with the advertisement by clicking on it. (Simply moving the mouse over it is not sufficient), the advertisement may do any of the above.
    Rule 7: Automatic video playing and audio are permissible despite rules 4 and 5 if the advertisements are part of video playback.

    Rule 1 explanation: It must not be a popup or pop-under.
    Rule 2 explanation: None of those flash adds that project an appendage over the page, that can only be closed after the animation is finished, and usually by explicitly clicking on some part of the advertisement. Further, no pseudo-popups (utiling CSS to create what looks like a popup, but is actually part of the page), unless they do not cover the page content.
    Rule 3 explanation: Non of those double height horizontal advertisements.
    Rule 4 explanation: Those flicking adverts are obnoxious. Actual video can be processor intensive. However reasonable vector based animation is fine.
    Rule 5 explanation: Obvious.
    Rule 6 explanation: Once a user clicks on the advertisement, it may play video, play audio, overlap the page, etc.
    Rule 7 explanation: That is to say, that advertisements like Hulu's and ABC.com's Full episode player are permissible.

    However, there are all too many advertisements that violate those rules, which is why I do run adblock.
