Short Description
With “Deactivate Plugins Per Page” you can easily disable plugins on certain WordPress pages (or on all except a selected page).This is useful for speeding up your site mainly because many front-end plugins will load their JavaScript and CSS assets on every page, even if you use them on one page.
How it works?
You can add deactivation rules for active plugins. For example for a contact form plugin, that you only use on the contact page, simply add a rule to deactivate it on all URI except on the contact page.
