the title explain everything. i used tagmanager and triggered events as it ask to and it works as i expect with all browsers exept firefox. any other(opera, edge, lynx, i.e. and of course chrome) answer really well: they fire tags and convert events on analytics.
if you just wait for the REAL TIME user passing on the website if i use every kind of system and every kind of browser, GA register me and when clicking on trigger, itercept the event; but if i am waiting with FIREFOX on the website i can stand in ther for the 30 minutes but nothing changes, the user you can see in the "right now" panel is 0 (zero), same if you clink on the triggers trying to see if GA may catch the event.
So i think,...maybe GA doesn't know how to track firefox user or they just have a problem with FF browser to catching the real time events and it is possible it register some firefox events in the "normal" way, days later...NO! in the traffic, public if i ask GA for which browsers users used...THER IS NO FIREFOX USER and that is no possible in 9 months in a website with 87% of users coming from Desktop (not mobile) noone use firefox, just me 1 person have to register a firefox browser. don't know if i can install an extension to my analytics to track firefox events or if GA is Just kidding people use browser different from chrome.
of course i remove the "DO NOT TRACK ME" option from firefox, and MATOMO(the new PIWIK) register me, but GA NO!
help...may i install something to my analytics or just it sucks and it is better to use it nomore?
