whenever I add a restartless to my firefox 29.0.1, it does not load.
I developed an add-on with add-on sdk. I was displayed in the browser through "cfx run" but when i installed its xpi in the browser, it doesn't load there. when i checked the about:addons=>Extensions, its present there. Then I installed another add-on (The Addon Bar (Restored)) from mozilla but same problem. I even did reset my firefox. I will be thankful for your help.

It is possible that there is a problem with the file(s) that store the extensions registry.
Delete the extensions.* files (e.g. extensions.json, extensions.sqlite, extensions.ini) and compatibility.ini in the Firefox profile folder to reset the extensions registry.
New files will be created when required.
See "Corrupt extension files":

If you see disabled or not compatible extensions in "Firefox/Tools > Add-ons > Extensions" then click the Tools button at the left end of the Search bar to check if there is a compatibility update available.
If this hasn't helped then also delete possible addons.json and addons.sqlite files.
You can also check for problems with preferences.
Delete a possible user.js file and numbered prefs-##.js files and rename (or delete) the prefs.js file to reset all prefs to the default value including prefs set via user.js and prefs that are no longer supported in the current Firefox release.
