For the past few days, Firefox has been extremely slow to load pages at startup. The browser itself launches pretty much instantly, but it's taking over six minutes after that just to look up domains. At some point it gets past whatever hiccup is holding things up and browsing works for the rest of the session -- noticeably slower than usual, but usable.
It happens with add-ons disabled, after multiple refreshes, and even after a full reinstall (with new profile). I've played with all the common suspects -- disabling accessibility options, hardware acceleration, IPv6, etc. I closed my pinned tabs and disabled auto-restoring the previous session. I even disabled Avast and MalwareBytes. Nothing has helped so far (which is seriously disappointing, considering the 6-minute restart between each change!)
The odd thing is that there are a few seconds, immediately after startup, where things seem to work normally. If I'm quick, I can sometimes get most of one webpage to load before the problem begins.
I've been a Firefox power user since version 0.6.2 and never encountered anything like this. I'm very comfortable with changing settings, configuration files, etc., and am willing to try just about anything to get things cranking again. But right now I'm simply out of other ideas to try.
Using 61.0.2, 64-bit version on fully-patched Windows 10 on a very fast fiber connection. <edit> I also tried the 32-bit version; no joy. </edit>
