Why I don't need IE7 or Firefox

On the 19th, I installed IE7 beta2;
On the 23rd, I finally could not bear to delete it;

In the past year, I have installed Firefox four or five times;
It took less than two weeks to delete all of them ......

I admit that I am not satisfied with IE6. tab is not supported, the interface is not neat, and operations are not convenient ......
However, for me, IE7 and Firefox, although they look pretty good, they are actually useless.
(This is like a man. If his wife is not satisfied, she is also a wife. It is impossible for a girl to spend more time on the outside: P)

First of all, let's talk about Firefox. This is a well-respected browser, especially for users on Linux and other opensource platforms. It can be said that it is neat and exquisite, and users are more operational than ie6.
Unfortunately, my main work is. NET development. I often need to browse many technical websites, especially msdn. However, I found that when using Firefox to browse the msdn kb, there are often the following invisible phenomena (what seems to be blocked ). Indeed, this may be because Ms does not comply with HTML/CSS specifications, but for a ms. for net developers, to some extent, when the MS specification conflicts with the W3C specification, the MS specification is more important ......
What's more serious is that our company's internal system cannot be logged on with Firefox at all-the error "this user does not exist" may occur. The cause of this error is that a javascript on the page does not comply with W3C specifications. In addition, even if the login is successful, the attendance system and salary system still cannot be used-the two systems explicitly require that only IE6 login be allowed.
In desperation, I wish to delete Firefox-a browser that looks pretty good.

If the Firefox lover is helpless and forced to abandon her, IE7 beta2 can be said to be a charming appearance, empty vase in the belly.
First, I had trouble switching the Input Method in IE7. Originally, you can switch between Chinese and other languages by pressing Alt + shift, but in ie7beta2, you can only switch to English and Japanese for some reason;
Second, IE7 will be inexplicably "white screen", that is, when I open IE7, it stops responding; sometimes switching between tabs will also cause IE to stop responding.
The last and most fatal point is that my proxy server will be inexplicably "invalid": because the company is an enterprise intranet, all external web access will be via an HTTP proxy server. Then, I often found out that I couldn't connect to the server when I tried to refresh the page a few hours ago. In this case, only the new IE (not the new tab) can be opened normally.
In addition, in terms of user operability, both tab and multi-instance (window) are supported. Although there is one more option, it also causes inconvenience. Due to business needs, I often open more than 30 pages. Some of these pages are automatically displayed in a new window, while others are in a new tab. The result is that there are 6 or 7 IE7 windows on the taskbar, and one to five or six tabs in each window. It is hard to find a page ......

Therefore, I had to go back to IE6 and try Firefox again when I tried to be "romantic.
Maybe there won't be so many bugs after IE7 launches the official version, but now, I can only say sorry.
