I'm in Hotmail all day everyday and have no issues. When I get a new email, the pinned tab has a little red dot on it. see screenshot

Show us your issue and block personal info.

It displays mail from Tigerdirect.com, etc. but I had to go on another server to see your email!

This is an ongoing issue! It's been happening for MONTHS! And today has been no different! I've had Hotmail open ALL DAY and NOTHING showed up in Firefox, but when I opened Hotmail in Pale Moon, as usual, NO PROBLEMS and ALL new emails showed up! Firefox just gets worse and worse and worse and worse! And at least two of the emails sent to me were time sensitive issues which needed to be dealt with TODAY, but I didn't find them until opening up PALE MOON browser just now at 10:41pm on a FRIDAY NIGHT! This is UNACCEPTABLE! Firefox, do you even CARE about your users anymore!? It certainly doesn't seem like it! This is also after DAYS of emails coming in to Hotmail and saying that there are new emails (by increasing the numeric amount in the upper left column), but the only way I could access them was to click on Junk Mail, then on Inbox, and then and ONLY then would the new emails become VISIBLE! Then you updated yesterday which solved that issue so that the emails would finally show up when they came in, but that was yesterday. TODAY it was back to not only not making the incoming emails visible to me in addition to adding to the number of emails in the upper left column, but not showing ANY new emails AT ALL, ANYWHERE in my account!

FIX THESE ONGOING and INCREASING issues!!! This is BEYOND ridiculous!!!

Well, that's just great for you, but obviously others of us ARE having REPEATED issues. SOMETIMES I get notices of new emails, but lately, nope, they don't show up in my inbox, only notifying me that yes, I have new emails (with the red dot indicator as well as an audible sound) but they do NOT show up in my inbox, and today (as explained in my reply above) NOTHING showed up, letting me know I have ANY new emails! Not in my inbox, nor in my junk folder!

And before you ask, I use Win 7 (and no, I will not DOWNGRADE to Win 10). I do NOT have this issue with Pale Moon. Pale Moon shows me new emails EVERY TIME they come in. Only Firefox decides to not work properly and FAILS to update my inbox and junk mail to let me know I have new mail!

Firefox is also OFTENTIMES slower than molasses to refresh pages and navigate to new websites!

Oh yeah, I also forgot to mention that I cannot tell you how many times I get false notices (red dot indicator) of new emails. The red dot will show up, and I click on the tab for Hotmail, but there are NO emails, even when I click on junk mail and back to inbox. They are FALSE notices! That gets irritating as well because it will happen multiple times within a ten minute time span.
