You can't delay Add-ons startup, they will start up when Firefox starts up. Using add-ons brings with it the risk that it will slow down Firefox or bring other performance issues. Either reduce the number of add-ons that you have installed, or find alternatives that don't reduce performance.

If you have a lot of extension then you can consider to use multiple profiles and only install the extensions in the main profile that you really need.

See:

• https://developer.mozilla.org/Mozilla/Multiple_Firefox_Profiles

You can add -no-remote to the command line to open another Firefox instance with its own profile and run multiple Firefox instances simultaneously.

The add-on which i am using is Adgaurd !

Is that an ad blocker. Disable it to make sure it is the cause of the problem. You could also try other blocking add-ons.

Have you tried contacting Adgaurd support?

Finally uininstalled it :)

Yes it is an Ad blocker & eats less system resource as compared to Ad block plus. See the link -> https://addons.mozilla.org/en-US/firefox/addon/adguard-adblocker/

I have AdBlock, no real problems.
