• Speed up Our Firefox Browser

  Date: 2009.04.02 | Category: Software, Web Front-end | Response: 3

  So far as we know, Fire­fox is a power­ful and easy-of-use web bro­wser in the world. Alth­rough Chrome is beco­ming better and better, but without exten­sion fun­ctions, Goo­gle Chrome will always be my second choice to use. Indeed, Chrome is much qui­cker than Fire­fox, while it spends more memory spa­ces for its San­dBox model.

  Recen­tly, I saw an arti­cle talked about how to speed up fire­fox by edi­ting some para­me­ters in about:config. Let’s have a try!

  Reduce the amount of RAM Fire­fox uses for its cache fea­ture

  1. Type “about:config” (no quo­tes) in the adress bar in the bro­wser.
  2. Find “browser.sessionhistory.max_total_viewer”
  3. Set it’s value to “0“;(Zero)

  Inc­rease the Speed at Which Fire­fox loads pages

  1. Type “about:config” into the add­ress bar and hit Enter.
  2. Alter the ent­ries as follows:
  Set “network.http.pipelining” to “true”
  Set “network.http.proxy.pipelining” to “true”
  Set “network.http.pipelining.maxrequests” to some number like 10.

  This means it will make 10 reque­sts at once.

  3. Lastly, right-click anywhere and select New-> Inte­ger. Name it “nglayout.initialpaint.delay” and set its value to “0“;.(Zero)

  This value is the amount of time the bro­wser waits before it acts on info­r­ma­tion it receives. If you’re using a broa­dband con­ne­ction you’ll load pages faster now.
  Optio­na­lly (for even faster web bro­wsing) here are some more options for your about:config (you might have to create some of these ent­ries by Right Click –> New– > Inter­ger or String

  network.dns.disableIPv6: set “false”
  “content.notify.backoffcount”: set “5“; (Five)
  “plugin.expose_full_path”: set “true”.
  “ui.submenuDelay”: set “0; (zero)

  Reduce RAM usage to 10MB when Fire­fox is mini­mi­zed:

  This little hack will drop Firefox’s RAM usage down to 10 Mb when minimized:

  1. Open Fire­fox and go to the Add­ress Bar. Type in about:config and then press Enter.
  2. Right Click in the page and select New -> Boo­lean.
  3. In the box that pops up enter “config.trim_on_minimize”. Press Enter.
  4. Now select True and then press Enter.
  5. Restart Firefox.

  That’s all! After my trying, I think it rea­lly faster a little bit than before. Great!

• 在IE6里准确显示较小高度的DIV层

  Date: 2009.03.23 | Category: Web Front-end | Response: 1

  在做网页设计的时候，尤其是给咱们国内做网站，一定要考虑到兼容性的问题。Firefox、Chrome、Safari、IE8这类对于CSS标准支持的比较好的网站，基本上测试一种就差不多行了（一些Javascript除外）。但是对于IE6、IE7这两个浏览器，要区别对待。特别是IE6，支持CSS一点都不好，自己说了算，但是在国内却有数量庞大的电脑依然在使用IE6浏览器。我想这与安装了盗版XP并禁用了自动更新功能有关吧。

  转到今天的主要话题。在给一个朋友做网站的时候，发现有个小问题。在我定义的一个div层中，只有一条横线，高度为4px。在IE8、Firefox、Chrome中均显示正确，但是在IE6中却显示出了三条线，而这个div的高度也增加为15px。于是我将高度设成10px，依然不见效，但是设置成30px的时候，高度就增加出来了。这说明这个div盒子里面并不是空的，尽管我在<div></div>中间连一个空格也没有。

  没错，这就是字体虚占位了。IE6默认按照字体大小min-height了一下这个div层，才会出现如此的问题。所以我们将计就计，把字体大小设成0不就好了？再加上一个overflow的hidden，一切就完美了。

  建议定义一个css的class来处理这类的问题，我是这么干的：

  .miniboxhack{font-size:0; overflow:hidden;}

  问题解决了。
