Dan upgraded to OS X Catalina last week, and he's starting to get a warning that Google will be able to read, delete and compose email in his account. Leo says that isn't from Google. He suspects that Dan may have an extension installed in Safari that's causing that, or that it could be a standard European GDPR warning message. But even if he approves it, he can revoke the permissions in settings. But first, look at extensions. Safari-Preferences-Extensions.
Brian has a series of VIVOTEK IP cameras. But he can't cast to Safari, Chrome or Firefox. EDGE and Explorer work though. Leo says that he may need to install an extension, and it may not be available. VIVOTEK may not have written plugins for it, or it may use a technology which other browsers don't support. Browsers have depreciated some of those plugin technologies lately. And chances are, they aren't secure.
From the chatroom, there is a way and here's a video on it - https://www.youtube.com/watch?v=JEPuhmPIzm4
David would like to expand his mesh router network to his shop outside. Leo says he can do it by putting an Orbi Satellite into his workshop, and just put his Orbi base station in the Window sill. But if his shop is 150' away, then he'll be out of range. Then he'll have to get an outdoor Orbi base station.
Alan has been having issues visiting a website on his computer, but his wife can do it on hers. Rich says that it could be that if Dave had installed a program recently, it could be interfering with his web browser. Another possibility is that Dave's Java isn't updated. He should try updating that. Also, Dave should turn off all of his browser extensions. If he can access the site after that, then he'll know that an extension is the culprit. To find out which extension is causing it, he can just go in and turn each extension on one by one until the site doesn't work again.
Doug's in laws are getting popups in Chrome using Facebook that malware is on their machine asking them to download something. Leo says that is a fishing scam trying to get them to download and install something. Leo suspects that there is a malicious extension in Chrome that is causing it. Leo suggests resetting Chrome to wipe out everything. They'll have to reinstall the extensions, but it's the only way to be sure. They should go to Settings and search for Reset. That'll make it go away.
Every time Ed opens up Firefox, it goes to Google. He keeps changing it to another page and it goes back to Google every time he opens it. Leo says it sounds like it's been changed in the settings by an extension or toolbar. Many companies make money by having their extension on your browser. Ed should right click the icon and select Properties. He should look to see what the shortcut is. He should try resetting his browser.
Art has issues with Windows 10 giving him an error message for shutting down. Leo says that Internet Explorer on Windows 10 isn't the default browser, Edge is. It has been in a kind of unfinished state until recently, though. If Internet Explorer is crashing a lot, Art should clear the history/cache and reset the browser. Leo says that the most common cause of crashing in Internet Explorer is plugins. So there's probably a bad extension in there that's causing it to hang up. It could also be a damaged version of Flash.
Hope uses Windows 10 and when she goes to a website, she doesn't see any images, just text. Leo says to refresh the page to reload. She can press Shift F5 and that will reload the page. There may also be something that's blocking all the images, like a plugin or extension. Hope uses an ad blocker and that could be doing it. Leo has a hunch that something is running on the system that's blocking it. It could be an overzealous antivirus program. There could also be an extension in Google Chrome that is blocking it.
Andrea is having trouble using Google Chrome. She even tried to remove and reinstall it. Leo says one possibility is to try and run Chrome in safe mode. If this works, then there may be an extension that's corrupted or broken and therefore breaking her browser. There could also be a malicious extension. Andrea should also clear her cache.
