I just came to know about NoScript, but after installing it opened the author's homepage with an advert for 'SpeedUpMyPC' that pointed to a UniBlue website, which I found fishy. Googling turned up this, but it's been many years now since that time. So how do I know whether NoScript itself is not some kind of malware downloader? I don't have the time to read the whole source code, and there are parts that are obfuscated. I couldn't find any evidence that the current version of the addon had been reviewed carefully, so how can I trust it? If not for the Mozilla addons site reporting that NoScript has 2 million users, I would have immediately classified NoScript as highly probable malware.
This issue was brought up in this forum post (archived here), but all questions went unanswered.
Let me specify my questions clearly:
Is NoScript malware?
If it is, why is it on the Mozilla addons website?
If it isn't, why does everyone say that UniBlue is malware? How can a program be considered clean if it opens a webpage with a link to malware?
Even if NoScript is not malware, does it surreptitiously contact the author's server for any purpose whatsoever, including updates? I want it to do absolutely nothing else other than block scripts.
The link on the NoScript website is https://noscript.net/jo/zp/piexgrhdc48ZOORjo
. I purposely broke the hyperlink because I don't know whether it is malicious.
Notes
The above link is in fact a 302 redirect to http://uniblue.com/cm/c/?aff=3257&x-at=noscriptb1&r=http%3A%2F%2Fwww.uniblue.com%2Fcm%2Fflashgt%2Fspeedupmypc%2Fnoscriptb1%2Fdownload%2F%3Faff%3D3257%26x-at%3Dnoscriptb1
, which incidentally has a robots.txt that Archive.Org respects and hence doesn't save it. Either way, the UniBlue page states everywhere on its website that it is a Microsoft Partner, and I seriously doubt Microsoft has anything to do with them.
I also found this MyWOT forum thread denouncing UniBlue.
