I was having a few issues that made me upgrade my x notifier and as a user of this product for a very very long time . I am wondering if there will be a bug fix as i read reviews when i was making one there and noticed on reading I am not the only one with issues with the latest firefox...My notifier no longer at all.... will auto check on timer at all.. only if i manually click ' check now' will it bother to check for me ..
FYI
Just FYI... my Firefox, upgraded to 45.0.1, with X-Notifier 3.5.19 auto-checks my email just fine, no problem.So it's not necessarily a bug with X-Notifier. Have you tried creating a new user profile in Firefox and then installing only X-Notifier in that new Firefox user profile? User profiles/addon settings can get corrupted.
