Browser context menus
No “Save Page As…”, no “Send Link”, no “View Background Image”, no “Open With Editor…”, no “View Page Source”, no “Inspect Element”…
Cannot print using your browser’s print function and expect a multi-page document.
Password manager, sync
Just remember it, okay?
“Screw you, and your privacy”.
Caret-browsing text selection
Cannot fully navigate using the same conventions as the browser.
⌘ + Click / Right Click
Cannot choose to open a part of plugin-based content in a new tab
(like viewing gallery images in tabs).
Browser extensions cannot operate upon the text or images within the plugin.
User stylesheets / User scripts
No accessibility override, like your choice of fonts and colours. No customisation. No patches for broken browser support. No “No Style” choice.
Drag and Drop
Cannot drag images out of the plugin to save to disk.
Cannot scale the text with the rest of the page.
No Firebug or Web Inspector. No source code. No breakpoint debugging.
There is no job that plugins are the right tool for.
Saying that plugins ‘have their place’ is ignorant and complacent.
