I have been using Waterfox for some time now, and I generally really like it, and since it appears to be using QT I do not have that annoying mismatch I tend to have with Firefox and Librewolf. However I did recently become aware that it’s owned by an ad company, my general question is have they done anything spooky yet? also while this might come off as a general paranoia are the accounts I logged in using Waterfox safe
Mine seems to intergreat, has the KDE title bar and such, rather than Firefox which is just the GNOME ones
No Firefox uses GTK.
You can disable SSD (server side decorarion) to get the in-line buttons, in the “customize appearance” screen bottom left.
Oh cool!
