How to temporarily block a web site for testing lost connection

At my work, I need to test whether a web application return proper errors when the connection is lost.

I searched and tried several site blocker add-on for Chrome and Firefox, however, most of them are design for blocking the site that aren’t work related, but I need to find the one for work related web sites. 😛 In other words, I am looking for the add-on that provide an easy way to toggle the block/unblock function, so I can work.

I have tried the following:

  1. StayFocused (Chrome): This one let you set time limit on the web sites that you try not to spend lots of your time on. However, it does not provides the easy toggle.
  2. Temporary Site Blocker (Chrome): This one is pretty close what I need, it has a button and a clean menu to let you enable and disable the blocking. However, it does not block the action on current page, i.e. you can pretty much to anything before you leave the page. Not I want.
  3. BlockSite (Firefox): This one does not provide a cute icon in the UI that do the toggle, however, I can check/uncheck the “Enable BlockSite” in other tab to achieve the same.

So far I am using BlockSite for this purpose. But I guess there should be some better add-on for this.

Firefox Speeddial-like plugins: FastDial and SpeedDial

One Opera feature I like is speed dial. It’s built-in, able to customize the row and column numbers, and can sync among computers. I kind of wondering why other browsers haven’t copy it, at least not in correct way.

Google Chrome does have similar feature, but it only show site you frequently visit and cannot change the number of the thumbnail, nor do they have an very intuitive way to set it as home page. Safari also have this feature, but the method of adding the speed dial items is so weird that I still cannot figure out how (who said Apple has the best user interface?).

Nevertheless, Opera does give me a hard time nowadays, the most deadly one is lack of support of synergy. If I see something interesting in computer A and want to copy to opera in computer B, I have to do following:

  1. Copy from Opera of computer A
  2. Paste to gedit of computer A
  3. Copy again from gedit of computer A
  4. Paste to gedit of computer B
  5. Copy again from gedit of computer B
  6. Paste to opera of computer B

See why I am frustrated?

That’s why I start investigating firefox’s counterpart: SpeedDial and FastDial. They both have the ability to show the dial, and able to adjust the number of rows and columns. When comparing between these two:

Briefly speaking:
SpeedDial:

  • Pro:
    • Nicer UI
    • Can define groups, each group has
    • Many more to customize, like refresh frequency in minutes, hour, day
    • It even has a weather dial!
  • Con:
    • Does not sync with xmark

FastDial on the other hand, has poorer UI, less customable than SpeedDial…
but can sync with xmark, as it actually posts as a folder in bookmark.

Currently I choose FastDial, as I have four working computers at the moment. But if you don’t need to sync, SpeedDial is a better choice.

Nevertheless, FastDial is not yet mature. For example, position of dial is not remembered, so when importing for a new computer, the dial item is arranged by the date you add the bookmark, not the order in source computer.

Browser comparison.

Today I installed Google chrome on my Windows XP box. It’s a HP compaq nx6120, no extra modification except I change to a 100 GB harddisk.
I opened a few web pages that I often visit and compared the memory consumption among Firefox 3.5.3, Opera 10.0.0, and Chrome using the about:memory. I was quite surprise what I saw:

But after a few minute later, it becomes:

It appears that chrome does some optimizing behind the theme.
