In the past few days, the problem that the SWFUpload control is not compatible with Firefox has inadvertently pulled out this flash problem. As we all know, the SWFUpload control uses flash to upload files, which is why it is compatible with multiple browsers. However, it has relatively high requirements on the version of flash in the browser, which must be installed and up-to-date.
The SWFUpload control runs in Google. If the flash is not up to date, the place where the flash is displayed will become a small puzzle, and you can see that there is a problem with the flash. But Firefox is different, nothing is displayed, and there is no response when clicking upload. Because of this, every time it is defined as "there is a problem with the code, because the flash control just installed must be the latest". After Baidu got this flash, I found out that there are different versions of this flash according to different browsers. It is useless to install the latest version of Google flash in the Firefox browser.
There are many ways to solve the problem that the browser Adobe Flash Player is not the latest version. There are many ways on the Internet. Here are two good ones. I am afraid that bloggers will delete them and find them later.
first time:

(Note: I only reprint the content here without sticking pictures. If you need pictures, you can read the original text. In addition, the content has been modified according to personal experience.)
1. First open the browser and log in to the website [ http://www.adobe.com/cn/ ];
2. Click [Menu] in the upper right corner, find and click [Adobe Flash Player] in the pop-up black dialog;
3. After opening the page where [Adobe Flash Player] is located, some will automatically recognize your current operating system and browser and automatically match you with the required flash controls (such as the 64-bit win7 Firefox browser I use, it automatically configures it for me) flashplayer24_va_install.exe) If it meets the requirements, click [Install Now] on the right. Some are not recognized or you want to download plug-ins for other browsers, then click [Do other computers need Flash Player? ] (previously [Do you have another operating system or browser?]).
4. According to your own situation, first select the operating system (I chose win7/Vista/XP here) and then select the flash version. It should be noted that when choosing the version of Adobe Flash Player, be sure to see which browser you download the plug-in for:
FP 24 for Opera and Chromium - PPAPI
FP 24 for Internet Explorer -ActiveX
FP 24 for Firefox -NPAPI
(Google has to choose the PPAPI version, and now Google Chrome has stopped supporting the NPAPI version of the plug-in.
In addition, according to the name of each flash plug-in, you can also see which browser this is.
flashplayer24pp_va_install.exe: pp--->PPAPI---->Google
flashplayer24ax_va_install.exe:ax---->ActiveX---->IE
flashplayer24_va_install.exe: (nothing, default NPAPI Firefox)
A special reminder, pay attention to remove the tick "√" of the optional program, otherwise the optional program will be installed. After configuration, click the [Download Now] button.
5. Double-click the downloaded exe to execute the program to install. After the installation is complete, restart the browser.
