This problems started when FF was updated to 38.x. I was hoping the latest XN update would fix this but it does not. I have even tried the X-notifier 3.5.9b1.
Here is what happens:
When I click on the XN envelope and there are updates to my XN Feed, the Tab spawns, but is blank. If I click on the RSS Feed on the left side, that Tab which was blank will now open with some contents.
May have found cuase
For my 1st RSS feed, I have the time set to 720. I changed it back to 10 and it worked. I just changed it back to 720 and will see what happens.
EDIT - Disregard, that was not it.
Am I the only one with this
Am I the only one with this problem? It seems the RSS feed is not fully loading its session? Once the blank tab is present and I click on the RSS feed, the tab fills up with the web page contents.
Found a temporary fix
If I have the option to "Check on Startup" selected, I get a BLANK Tab when the RSS feed is spawned. If I uncheck that option and manually check mail by selecting "Check Now", when the RSS Feed is spawned, the web page contents are shown.
