Not a tech. FF was free and decent. Last several versions if I didn't update, repeated, annoying reminders that got worse and larger and harder to remove as I blocked them. Now on FF 71 I find out I have to 'reload' flash every time I play certain games, that FF removed the 'always activate' option. I would use an older FF version but then here come the interuptive reminders. Never tried Chrome and IE used to be a joke. Might be time to try something else. BTW, I'm a huge W7 fan, W10 as I understand it requires promises to MS to allow them to keep their hands in my computer. UBUNTU scared me when I tried it years ago and I have no use for Apple. Sad that was once a great, free, hassle free internet has become a cesspool of greed and a line of arrogant egomaniacs trying to control every aspect of it. If I wanted that crap I'd follow the news, people, and politics. Glad I'm 65. CIAO!
Firefox I consider no better than Chrome. As I prepare to transition from XP Pro to Win 7 Pro, it will not survive the move. I will only be using derivative browsers on my new rig. Been hating Firefox for a couple years now, but tolerated it because of the addons, and it was one of only three browsers that kinda sorta work on XP. With Mozilla Mothership's edict to mass sabotage the addons, combined with the developers OCD-like fixation on preventing user customization, packing in surreptitious telemetry (and forced autoupdates), it was time to be done with it....plus moving on to Win 7 gives me enough browser choices that I no longer have to use subpar ones. Over the last year I have forgotten how many times that poor excuse for a browser gave me a 'Firefox has a problem and needs to close', or it was frozen, or I closed it but it never stopped running and now I have to figure a way to really close it.
Chrome and Chromium browsers are LilBro Google's all-seeing eye, reminiscent of the '1984' novel. Some or all of the spyware has been removed from its derivatives (Iridium, Advanced Chrome, Superbird, Comodo Dragon, Epic, Slimjet, etc.), so these are safer to use. Basilisk, Waterfox, Comodo IceDragon, & CyberFox still allow addons, and likely have less telemetry, so I would count these as acceptable replacements to Firefox. I'd stay far away from IE and Opera. The latter functions like the worst malware I ever saw when I tried to uninstall it. For Linux, try MX Linux. I tried over twenty distros, and only it, Linux Mint, Kodachi Linux, and TAILS proved usable. Been running MX Linux in LiveCD mode nearly every day for about a year, and will be installing it on the secondary HDD (actually an SSD) on my new rig. It is easy to figure out, has an excellent user's manual, and a forum where the people are not uppity with newbies.
