Sending this using Safari because Firefox is totally messed up. Firefox 115.24.0esr (64-bit) OSX 10.13.6 High Sierra 2011 Mac Power Book (MPB) with 16 GB RAM. Verizon DSL line, download speed tests from 10-14 Gb/sec but Latency is always 400-900+ msec. No way to measure Jitter with speedtests that will run on my older system, or Bufferbloat now that DSLreports has gone dark. I want a tool that will allow me to see all the attempts to connect, and packets/traffic, to see it its my old computer going bad, Firefox, the wireless or wired connection to the DSL modem/router, or the DLS modem/router itself, such as a problem with reaching the Domain Name Server (DNS) etc. I can access the DSL modem/router in the browser, but there isn't much documentation. Its made by Actiontec but customized firmware for Verizon. The problem persists whether I am using wifi or an Ethernet cable. My wifes 2010 MBP computer with 8GB RAM using about 6.4GB, running High Sierra and Firefox 115.24.0 (esr) seems not to have the problem at all. Firefox will show something in the lower left corner, "connecting to..." or "loading..." etc. It can stall with either status. Search engines would be StartPage or DuckDuckgo. With DDgo, sometimes it just spins forever, but if I click on the URL bar, it drops down another line with the same URL and "--Visit" appended. Sometimes that will load, but seems random. Some URLs / links open in a few seconds, some spin forever. I first called Verizon Tech support on May22 about problems (see full exchange of repeated calls & new trouble tickets below). I think, IIRC, this happens to be shortly after I upgraded my Firefox version. They have admitted to PINGs not returning, packet loss, no excuse for the Latency. I do have a lot of pages/tabs open; Activity Monitor says my memory use is about 14GB, but the Memory Pressure stays low in the green. I also run Thunderbird, TextEdit, maybe Adobe Reader and Excel. But even when I close everything else, the non-loading issue persists. When I shut down Firefox, the memory pressure can go into the red and take a very long time (so I always shut down all other apps first). A recent shutdown stalled & I ended up losing many open pages/tabs, but even the slimmed down load has the same problem. I have shut off the AddOn NoScript, but the problem persists. ***** FILE: verizon DSL tech support WED 21MAY25 glacially slow web page connection 800-837-4966 AGENT DSL tech support failing the PING reset my IP address still fails PING trouble ticket MDHM03KR7A 2-3 working days for networking team to resolve THUR 22MAY25 call back from networking guy. they raised the speed to 13.4 but latency still 28, he says should be 15 max. Asked him to optimize by reducing download speed. will call back later or tomorrow.
