During recent days, when accessing a personal WS or domain's email system, have noticed that downloads of all email file folders are significantly delayed (up to about 1 min.) - often with message: "Firefox Not Responding" showing for some time (in top-left screen) - until whatever is problem resolved. Then, today, it was noticed that the "Not Responding" (or "download delay" problem) is apparently tied to these two descriptive items (procedures) that respectively appear - in order shown - at the bottom-left of the Firefox screen: 1. "Waiting for: ssl.google-analytics.com..." ("suffix" dots apparently indicate that the "WS address" continues - but due to "length restrictions" - rest is not shown), then 2. "Read: ssl.google-analytics.com..." (obviously, same dots reference same as is above noted). I then thought to access the same WS's email files using MS's Internet Explorer browser - to learn if there is some virus or worm or whatever tied to the former's email system. As quickly observed, neither MS's IE Browser nor the WS email system has the "download-delay" or "Waiting for ssl . . ." or "Read ssl . . ." problems or messages appearing. Why have the latter two actions somehow become part of the Firefox Browser. I prefer the Firefox system - and also use Thunderbird. So, why or what's happened? Has my installed (latest) version of Firefox somehow been corrupted? Best solution to resolve? Note: "Webroot" Security system is currently running and did not alert regarding any malware.
