Freesoul Deactivate Plugins
FDP allows you to deactivate plugins on specific pages for speed optimization, debugging, and problem-solving.
Specific Content for mobile

SCFM allows you to create specific content of pages and posts for the mobile version.

You love it if you want to remove some fat content and not just hide it. Or if the responsive design is not enough for some mobile pages.

Content No Cache

Exclude a part of the page from the cache.

You will love it if you need to cache a page, but part of that page should not be cached.

Free plugins
When I solve more than once the same problem, I prefer to save the solution in the form of a plugin.
I hope they will help you as they helped me. You will find some of them on the repository and others on this blog.
