Now has advertisement/cross-promotions for things like Facebook (Which has had a history and still does things like collecting your information to get money from and has advertisements/cross-promotions all over it, besides other privacy/security concerns!) and other commercial sites, solicits donations, and other annoying things like this whenever you rate a site at the bottom of the rating screen! (Besides soliciting donations some times a site is to be rated, it is random what actually pops up...) (Related, but might be slightly off topic: I on principle refuse to donate/upgrade via giving money to to any site that uses advertisements/cross-promotions at all (like this site now), or has strings attached similar to this, such as mandatory payment to upgrade to add "Full Features and Functionality" what was originally considered "completely free" or programs that pretend to be "FREEWARE!") (this add-on was not supposed to be an annoyance or proven some-what disreputable and possibly more untrustworthy in general by exactly doing this(advertisements/cross-promotion/soliciting donations other than their main site on the front-page legitimately ONLY!), but was supposed to be helpful and informative potentially to the public! That's what Mozilla and their add-ons are supposed to be about (good and free!), the best add-ons that exist for add-ons are completely free, are at least mostly private/secure, and very useful!!!) "Free" in general when it comes to anything from online does not mean advertisements, mandatory registration of information to use, or have strings-attached, or other hidden to using their "Free" product/service, this is not Free at all anymore when things like this are included!
