Get the source

You need SeLite source to get AppsFrameworks and PackagedScripts. You also need it to install development versions of Components. Check the source out with a GIT client (which makes receiving updates or managing local modifications easier). Alternatively, download SeLite as a ZIP and SeLite SelBlocks Global as a ZIP.

There are repositories for

Purpose Repository: files and details Download ZIP Clone from GIT Updates (XML feed)
SeLite source (except for SelBlocks Global) source Download ZIP Updates (feed)
SelBlocks Global source source Download ZIP Updates (feed)
Documentation source Download ZIP Updates (feed)

Install components from source

(If you’ve already installed any SeLite components from downloads, uninstall them and restart Firefox. Only then apply the next steps.) Run SeLite\setup_proxies.bat and SeLBlocksGlobal\setup_proxy.bat (or SeLite/ and SeLBlocksGlobal/ on Mac OS/Linux). You can provide a Firefox profile name as a parameter, otherwise it uses default profile. After setting up proxy files, start Firefox (with that profile).

You may need to accept components (add-ons). Verify that all SeLite components are enabled at Firefox menu > Tools > Add-ons > Extensions.

Apply DevelopmentTools, especially set xpinstall.signatures.required to false. (See MDN Signing and distributing your add-on).

Restart Firefox.

Components set up this way won’t receive any updates. You’ll need to run GIT pull (or download a new .zip file and extract it at the same location).

Install Selenium IDE from source

You’d need this only for debugging Selenium IDE, or custom add-ons that override it.

If you’ve already installed Selenium IDE, uninstall it and restart Firefox. Then you have the following two options.


Download Selenium IDE as an .xpi file, but don’t install it (right click at the link to an .xpi file > ‘Save Link As…’). Then unzip the .xpi file (you may have to rename it to end with .zip). It contains several .xpi files inside, and you want selenium-ide.xpi. Unzip it and point a proxy file to the unzipped folder. All that is done by the following steps for Linux. For Windows or Mac OS see setup_proxies.bat or above and figure out similar steps to the effect of the following.

cd ~/.mozilla/firefox/*.default/extensions
# if you have Selenium IDE installed already from an `.xpi` file, turn Firefox off and:
   rm -rf \{a6fd85ed-e919-4a43-a5af-8da18bda539f\}.xpi

mkdir selenium-ide-X.Y.Z
cd selenium-ide-X.Y.Z
unzip ../
pwd > `echo ~/.mozilla/firefox/*.default`/extensions/\{a6fd85ed-e919-4a43-a5af-8da18bda539f\}

Restart Firefox.

This way you won’t receive any updates. Subscribe to RSS XML feed of Selenium IDE versions.

From GitHub

git clone
cd selenium
cd ide/main/src

Either wget, or download it raw. Alternatively, copy its code and save it as

pwd > `echo ~/.mozilla/firefox/*.default`/extensions/\{a6fd85ed-e919-4a43-a5af-8da18bda539f\}

Restart Firefox.

Debugging Selenium IDE

For debugging Selenium IDE, apply DevelopmentTools > Debugging. Then use Firefox > Tools > Web Developer > Browser Toolbox. You need to know a file name. Identify the file using grep or some other text search tool. For easier code navigation create a NetBeans project. See DevelopmentTools > NetBeans as a Javascript IDE.
