Reliable and with multitude of functions - that's not easy to combine, but here it works like a harm. Superb! Thank you very much!

Exelente

Cette extension remplit exactement ses promesses. WL

This addon is a must have.

Indispensable para ser prácticos al navegar por sitios cargados de imágenes. Que actualmente son la mayoria.

Ese es el mejor complemento

Нельзя даже сравнивать с расширением Thumbnail Zoom Plus. Очень мало увеличивает миниатюры и не все, некоторые уменьшает.
В общем работой этого расширения недовольна. Very bad.

Very handy and interesting.

C миниатюрами не работает, совсем никакого эффекта, картинки на сайтах увеличивает не все. very bad

good

great extension !

j'apprécie peu cette extension, je regrette Thumbnails zoom plus

Try using an old version of Imagus like 0.9.8.52, last workable version for my FF 52.
Imagus asks server for larger images by default, while TZP only zooms the thumbnail in the cache. Totally different "thumbnail"s.
Just in case some are too lazy to tweak around, enable advanced options, set "Activation with right mouse button" to "click", and "Minimum size-difference to zoom" to 0%, just so you can right click to put the popup at the center, then scroll up and down to zoom, or, when working with images that are in full sizes already, use Ctrl+Right Click to force a popup, then right click on that again. Use this whenever it won't show popups.
By default you can press 3 or 4 to take up full width or height of your browser to display images, NOT your entire screen like TZP does.
