Is embed.ly Safe?

I have no information of it being sus. My review (of my own preferences on what ground rules should get your site at "Default", "Trusted" or "Untrusted" on my system). I hate unnecessary stuff, I have a ass-load of tabs open in 11 windows.... I'm barely starting to get under 1000 tabs in 15 windows, it got out of hand. FireFox was annouyigly low and ate so much RAM free I could barely run Gimp, LMMS and Thunderbird - former two preferrably not at same time, still having at best even humongous "less than 4GiB free RAM of 16GiB - it wasn't a problem with ThinkPad T450s, which has one DDR3 connector just like X250, but former has already 4GB soldered DDR3 - I'm saying 4GB, because like disk companies, RAM companies have all long since decided to cheat - everyone knew it was 1024 KB in MB for storage (RAM and storage mediums to save on), and 1024^2 bytes for a GB, one *should* win court because there's no chance that the company producing mass storage devices or RAM know all about this, but still continued. But the judicial system is a bad joke with many fails. The one thing where the binary kilo's are not used and never have, is network transfer speeds. Say a modem with 28.8Kbps speed means 28,800 bits per second, which means it can transfer, aka. 3600 bytes per second (as the speed doesn't show kilo-, mega-, etc. bytes, but bits - Kbps=Kilobits per second, and one byte=8 bits), 3.6Kilobytes or even 3.515KiB (aka KibiBytes or binary kilo's). Oh course the nominal fee for me home VDSL is barely 10Mbps. But my monthly "4G packet" for a Prepaid SIM card in my Nokia, from which I share a connection to all my PC'c with Wi-Fi HotSpot. The pack has nominal 50Mbps 4G, meaning it can reach that with sites only on the connection providers local network while the mean connection speed is ofter like 25Mbps. Btw, this prepaid packet costs ~26-29€/month (24€ if 3G and nominal 21Mbps - and average reality between 8 and 16, but mostly around 14 is enough). Not to mention "unlimited" messaging (3000 and 6000 SMS's in month for free - depending on which packet you got). It also seems to allow free MMS's, but does it go with free unlimited data or does it count against the "SMS's left, don't know", but even 3000 SMS/MMS messages is unlimited to me. Phone calls to numbers with no extra charge are free - unfortunately while there are number codes for numbers that are paid services, but there's also some corporation reserved codes that can't be called because *some* offices numbers there are non free (free means only havng the regular price of phone calls set by provider - of course there are completely free services as well, that you can call from prepaid without saldo loaded to it nor any package). I always load the new package into queue when I got monthly cash, and if my saldo is low, I pay for 10€, or 5€ if I'm tight, for saldo to make sure that when rarely I have to call non-free number, I can. BUT I FRIGGING DIGRESS!!!!.... Thing is, this this site doesn't seem like necessary and I don't know if there's anything sus about them, it's only a domain that a site I came to wanted to load something, most often it's scripts or fonts, and I hate it. Dozen of 3rd party sources you have to access to load the site as they'd like you to, even if you leave all suspected of malware, tracking/profiling, etc. out - think is, I'm giving the benefit of doubt, but I don't know how the site would "work better" if I enabled it, but I know that that domain would AFAIK load as unnecessary bloat on every site that loads from them if I enable it in NoScript - and I don't have a reason to do that. I wan't my FireFox lighter, and while I'm going (sloooowly) through all the windows, closing stuff, merging or removing whole windows, and meanwhile I want to eliminate unnecessary resource consumers, and it seems to me like one, so I will have it at "Custom" (it tells me that it's not blocked for evil, when I later see it and can't remember why it's actually blocked. So my choice and recommendation if browser memory use and slow down causing bloat is an issue, and if you're up to the nuisances NoScript causes especially in beginning when almost every host is blocked and you have to allow them by hand site-per-site, then consider blocking this. It should not affect the main sites functionality - and you can try to temporarily allow it to check if you suspect it being responsible for glitches and bugs in the website you're on. Btw, I'm baffled why profiling nor tracking are not listed under tags you can choose to best describe the site. I feel oddly certain there used to be, but I might be wrong.
