ceasesmith,
I generally use Firefox for most things. Google Chrome is not the simple browser like it and Firefox and even MSIE used to be. They are bloated and slow, but Chrome is worse than Firefox. There will always be webmasters who either don't know how or more likely refuse to make their websites simple, fast loading, and user friendly. Some even have so much unnecessary script in their website, that the pages frequently take forever to load or crash the browser. Kinesis, Facebook, STN, and Excite Personal Home Page are four that instantlycome to mind.
Many times, especially with mystery shopping websites, the culprit is Flash. You could always turn off Flash, but it is necessary on many MS websites to upload your receipt images. If you are having new problems with slow page loading, not loading at all, freezing, or crashing the browser, I suggest you first check to make sure you have the latest version of Flash. If not, then update it. If your browser is set to auto-update, the new update may not work well with the old Flash version.
You should also disable all the cute add-ons, plug-ins, and cosmetic enhancements you might have made to your browser. If you find you need them, you can re-enable them one at a time to find which one(s) are causing problems. As I said earlier, some webmasters insist on bloating their web pages with excessive coding such as java and cgi script and others. This is why you should install a backup browser and use it for those websites.
I actually have 8 browsers on my home pc that I can use. I use only Firefox on my smartphone, since the Android version of Firefox is not full of bloatware. I have installed a lightweight browser on my pc that I use especially for websites that are overloaded with scripts and unnecessary bloatware. It is called FlashPeak Slimjet. It has the most effective ad blocker that I've ever seen. I would not install any unnecessary add-ons to this browser. Keep it simple so it will work for you when the heavy browsers will not. This browser is so good at blocking ads and crap, that Facebook (and only Facebook) always displays a notice at the top asking me to update my browser for a better experience.
MalwareBytes is not an anti-virus, and it is not a firewall. It is useful to use periodically to scan your pc to find and eliminate ad ware, which IMO is sneakier and harder to remove than most actual viruses. Some anti-virus programs think MalwareBytes is a virus itself. In those instances, you have to rename MalwareBytes to something more friendly to trick the anti-virus program. Although Windows does have a weak firewall pre-installed, almost every router has a firewall. If you have home Wi-Fi, you probably have a router connected to your pc.
SASSIE is the least troublesome and most user-friendly of all the MS websites, and I do not have problems with their pages. I wish all MS companies used it.
