I'm not seeing any ads with Chrome. I've noticed in the past that I get logged out if I'm inactive for a while then ads appear.
I just tried it using MS Edge and I see ads, but only on the forum main page and with the right sidebar open. No ads in the sub forums.
I'm running Edge Chromium with the extension Ad+ enabled. It's the ONLY way I can view this forum without ads. I quit contributing because it didn't remove the ads and questioning it didn't resolve the issue either. Sorry.
I've been using it since the early beta... and several times during the beta process, as it updated, it boinked a few of the extensions that I use and I'd have to reload/reinstall them.
Ad blocker and Ghostery stopped mine.
