Personally, I look in to eHam two or three times a day and have no big issues using Chrome (Version 109.0.5414.75, W11) on eHam.
However, I don't go to the front page and log in. I have a link that goes directly to the forums and I never actually log out. My login lasts for about a week, maybe 10 days, before I have to log in again. Once connected to eHam, I right click on the little eHam link (top left on the forums) and open just the forums in a new tab. This shows me only the forums without the eHam header and empty space on the left. From there I can see all of the forums and can navigate easily.
Last week there was a odd happening where two days in a row, I had to log in. That issue has not repeated itself.
The only issue I see regularly, when navigating the forums, is that the vertical scroll bar goes away sometimes. But I usually use a mouse wheel to scroll, so it doesn't bother me and doesn't stop me from navigating the forums. Eventually, the scroll bar comes back. Sometimes, when I mouse over a link on the page, the scroll bar returns.
Oh yes, I do run a ad blocker so I don't see any adverts.
