Absolutely trashing performance on firefox. I think this is in theory a great add-on, and it has been in the past, but it is unusable in it's current state

Spammiest piece of garbage. Like 6 slide in attention grab popups. Almost threw my phone in the river.

Peddles Malware.

look good on some site and not so much on others but the deal breaker is it slows down fire fox sometimes so bad firefox tell me it turn it off yikes

reenabled itself without asking. absolutely unacceptable. uninstalled

It literally broke the first website I tried it on.

Functionary not

It's been at least a month since the extension ceased to be functional. If they can ever return it to when it functioned, I'd be happy to re-install, but it's worthless for now.

This extension used to work flawlessly... years ago. Now, it's a broken piece of junk that routinely breaks pages, causes major performance issues with FF and tabs to crash, and makes text/images so dark as to be unreadable. I'd rather suffer through the blinding light, thanks.

On the visual side this add-on works very well. BUT it seems to have a SECURITY ISSUE, since when it is activated certain website logins (e.g. a bank) don't work anymore. I wonder how this is possible since the add-on supposedly only alters a websites colours.

I do not understand how this can be a recommended add-on. Yes, it does the job and it looks pretty and all that. But I have never had an add-on that made my pages freeze up and cause my browser to crash before this. It's almost impressive to see how they managed to mess up such a simple thing. Refreshing pages take forever and when I resize my windows all of my tabs lock up, stuck between the original width, to the new width and everything in-between. How do you manage to make something that is supposed to only change the appearance but somehow invents more problems??

Didn't appear on tool bar or tool-bar drop down. Didn't have any kind of settings like those show on website help page. Didn't do a darn. Bye-bye.

Pretty useless without a toolbar button to switch off.

No longer works at all. Completely useless.

Sending crap back to their servers.
