Max has a 13" Sony Vaio V series that has been freezing intermittently. He's isolated the application to Google Chrome. Leo says that Chrome is notorious for taking a lot of system resources, and Leo thinks the system could be overheating. Leo recommends trying Firefox until Chrome goes "on a diet", which Google is currently working on with their "Blink" project.
Shelly is having trouble typing in her web browser. When she types, all different letters show up! Leo says that it's possible that she changed the keyboard mapping and that's what could be causing it.
The chatroom says that a malicious toolbar could be causing the issue. Leo recommends disabling all the toolbars she has, and restarting her system. Leo also suggests plugging in a different keyboard. If that doesn't change it, then it's definitely software. It's likely a virus that's embedded in the toolbar.
Steve has a PC and Mac. When he uses Firefox on the Mac, however, he gets an error message whenever the browser would crash. Leo says that message is telling him that when he reopens the browser, the tabs and windows he had open will come back up when he relaunches the browser. He can disable this setting if he doesn't want it to do this.
Terry can't remember the password for iHeartRadio. How can she access the file that allows her to remember it? Leo says that Firefox stores saved passwords in clear text, which Leo says is a flaw that's just begging to be exploited. Go into Firefox, Options, Security, Saved Passwords. Show Passwords. She should just hide them after she's done.
Brian has an old computer with Windows 2000 and he recently got a message from Firefox that it no longer supports his operating system. Leo says that the computer is pretty old, and Microsoft has decided to end support for that OS. Unfortunately there's not much he can do.
It's possible to temporarily change fonts by pressing "control +" in any browser. He could also change the font sizes within webmail of most email clients. If he goes to Internet Explorer's options page, and goes to Accessibility, he can override font sizes there. He can also make a global font size change that will change it everywhere by just changing the DPI in Windows.
If everything else is working on that network, then it's clear the laptop is the issue. It's possible that they're using a WPA2 password and the laptop doesn't support that. Since the laptop isn't that old, Leo doesn't think that's it. She is getting signal on the laptop, it's just not connecting to the internet. It could be Internet Explorer. Try another browser like Google Chrome or Firefox. It's also possible that the laptop is mis-configured for the new network. It may also be that malware is causing it, such as DNS Changer.
