Multiple Mozilla problems
When using Mozilla/Firefox (but not when using Chrome) many links do not work (e.g tracking packages from UPS or FedEx). Also even though under setting I check"save logins and passwords for websites) they are not being saved. I need to login manually to access most websites
Please advise how to correct these issues. Due to security issues I greatly prefer to avoid Chrome/Google !

For FedEx, it could be a cookie issue or a blocker issue. Here's one "solved" thread for reference:
https://support.mozilla.org/questions/1374690 => If you run DuckDuckGo Privacy Essentials, use its toolbar button to make an exception for the FedEx site so it doesn't block things there
As for Firefox itself, check whether Firefox's Tracking Protection feature is blocking anything on the site. The shield icon toward the left end of the address bar usually turns a bit purplish in that case. Click the icon to learn more or make an exception. See: Enhanced Tracking Protection in Firefox for desktop.
Recent issue:
Firefox recently rolled out "Total Cookie Protection" to more users. This limits how sites can use "third party" cookies, meaning cookies from different websites than the one you see in the address bar. If FedEx shuffles you between multiple different servers (you see very different web addresses during login) then you might not get logged in on all of the related sites.
You can make exceptions to this feature when needed. More info in the following articles:
You can check the Web Console (Tools -> Web Developer) for messages about blocked content and about the presence of mixed or unsafe content.
You can check the Network Monitor to see if content is blocked or otherwise fails to load.
If necessary use "Ctrl+F5" or "Ctrl+Shift+R" (Mac: Command+Shift+R) to reload the page and bypass the cache to generate a fresh log.
