Super important time saver that doesn't disappoint Rated 5 out of 5 stars

This is a must add on for me. It allows you to preview the contents of a site URL. You can choose to hover over or click a star near any URL link which opens a preview of the link contents in a nice size floating separate. There are options to customize how quickly and in what manner you view the link contents. Once it's open, you can "lock" the view maybe while you read it without limitation (the view window can be dragged), open just open it in its own new tab, close it after reading, and some other things. I ALWAYS have this link on my toolbars or menu. You won't be sorry. I can't think of a downside to this add on.

Does NOT work with old google images Rated 3 out of 5 stars

I'm using this add-on since years and it helps me to pre-view sites, images, videos before visiting the main site.

Since Google has hidden all the names, resolutions AND website links from ALL the images in "Google Image Search", now the image search looks like on the mobile phone. Damn stupid idea from Google Imperium. I HATE it when I can not see what I am clicking.

Cool Previews does NOT work when Old Google Image Search add-on is installed. When I deactivate it then it works. It worked with Firefox version 28 sometiems it does not work. (By the way, I also HATE Firefox from version 29, 30 and up and I'm using ALWAYS older versions (max version 28) ).

Please do something to fix it because I really need Cool Previews when I search for images on Goggle. By the way, it works on all other sites good, except Google Image Search.

Fluently surfing with this preview window ! Rated 4 out of 5 stars

It allows you to see what is behind a link that you're thinking not enough interesting to open it into a new tab so far breaking your reading

A suggestion : Popping up the windows with the icon appearing besides the link would be surely more elegant with an smaller and discreet icon and why not just an superscipted arrow...

This is so cool :) Thanks :)

Much Quicker Data-Mining and... Rated 5 out of 5 stars

I tried them all and this is the best previewer. At the very first impression, I thought "meh"... But, after I adjusted the size, location, and settings it became "cool"... Once I started using it to speed up research, it became "invaluable". Just one example of many is when I'm in the PSN Store and find a game to buy, I turn on CoolPreviews and quickly check out the addons to make sure I'm not about to buy half a game with the other half as disc-locked content within addons (will await the complete edition game versions for those). Considering how slow the Sony Store is to load a page, this saves a lot of time (not only that, but for some reason, PSN pages load quicker within CoolPreviews, than normal... I timed it, they really do).

I don't use this all-the-time, but when I do, it really is invaluable. If I had a request, it would be to change the toolbar icon's "left-click" action to "Disable Completely" and "Enable". I don't see any reason for the left and right mouse button to perform the exact same action (loading the popup menu).

Awesome Add-on Rated 5 out of 5 stars

Cool Previews is an incredibly useful add-on that streamlines the browsing experience, making it more productive and efficient. I no longer have to click on a link to view its contents and then have to click on the back browser button to return to my original web page. The email, bookmarking, and pinning feature put this add-on over the top!

Annoying when it pops up, I don't always want to use it, it makes it difficult to click links sometimes, and other times I cannot mouse over the icon fast enough. I would like to be able to choose whether I want to preview a link, perhaps by right clicking it and selecting the option to preview, rather than having something pop up, and then I would like the preview to appear where I want it.

Awesome functionality. However the browser hangs when we do inspect element in the cool preview window and ultimately we have to force quit.

Works very well. However it has created a problem with scrolling.
I had to open about:config and set
general.smoothScroll to False.

Fade-in animation is irritating Rated 3 out of 5 stars

Firefox has a single-process engine yet (E10s is only at an early development stage in Nightly), so javascript animations look choppy and cheap while the content is being loaded. This is exactly the case with CoolPreviews. There should be an OPTION to disable the animations entirely and only show the preview window when the content mostly/wholly is loaded.

And I think the header toolbar could be streamlined with the new Firefox design which is flat and simple.

No.1 Addon to Mozilla FF. Superb but can STiLL be more functional and customizable Rated 5 out of 5 stars

This is the No.1 Addon to Mozilla I install whenever needed a new format and reinstallation... And perhaps the only or main reason I don't turn to another Browser (except sporadicly). - The only thing is that in the last v.31 of FF, the "Right-Click Preferences" Tab as well as the the "Right-Click Context-menu" CoolPreview Search Option has DISAPEARED ??? !!! I un-re-installed it, but still MISSING! I hope I'll find some luck to workaround in the "support page"... Otherwise, it's SUPERB, because it's functional; especally the Search Toolbar operation.
- One Hint - For even better functionality: A Keyboard-shortcut for the Left-Right Triangles that manage the PREVIOUs / NEXT PAGE in the CoolPreview Window WOULD BE more than GREAT.!!!
