Installation method 1: It can be downloaded from the official website: http://seleniumhq.org/download/, but because the selenium server is in the United States, the network between China and the United States is often unstable, and the connection often fails, causing the download to fail.
You can find the XPI installation file of the selenium IDE plugin to complete the installation.
Installation method 2: You can open https://addons.mozilla.org/en-US/firefox/addon/selenium-ide/ with Firefox , find the selenium ide compatible with the current firefox version here, add it to firefox, click " Add to Firefox" will do
Since this is the latest selenium IED, the minimum firefox version is 56.0, mine is 44, so you need to find a compatible version
Download link for the historical version of firefox: http://ftp.mozilla.org/pub/firefox/releases
Then check out other versions
find one that can be added to firefox
Then install it until you are prompted to restart firefox, then you can use it
In the tool, you can see that the selenium ide installation was successful
Open selenium IDE
