I have long used multirow bookmark toolbar extension to give me 4 rows of bookmarks across the top of my Firefox window on Windows 10. After updating to this latest version, the extension is gone. Any mention of it in about:config is gone. I don't know if it ever was mentioned in userChrome.css but it's not there either. It's as though it never existed. WTH?

Can anyone suggest how to get a multirow display of my toolbar bookmarks? Thanks in advance.

On a related rant: This is why I hate upgrading Firefox. Something useful and common sense always breaks. I'm going to open a separate question to figure out how to get the cursor focus back into the Google search box when I open a new tab using Google as the home page. None of the previous solutions is working with this version. This break in basic functionality has happened after many different upgrades of Firefox and I am frankly sick of fixing the same ridiculous problem over and over.

For the last two days, cnn.com won't load and gives a message that the browser is blocked. Can you explain how I can remedy that? It's a rather popular site, so I assume Firefox will want it to work. All my other sites are working fine, so I'm assuming it some adjustment that cnn made on their end.

Dear ladies, dear gentlemen,

on another Computer, when using Firefox, I am now constantly getting a Norton notification of a malicious domain request 22. The problem does NOT arise with the Opera browser installed on the same machine. What shall I do? Uninstall Firefox seems to be the best solution. Scans do not reveal presence of malware. On this computer, similar OP, this does not happen, but I use it much less.

Thanks a lot, Alexander

Whenever I change my VPN (not Mozilla VPN) status, Firefox will refuse to connect for something like 30 seconds then times out, leaving me with a blank screen. I have wait until that interval has passed before I can retry, otherwise it will repeat the freeze. This happens whenever I turn my VPN on/off or switch to a different VPN server. It happens only with Firefox. Chrome and my email client have no problems whatsoever. I think it's some kind of DNS caching problem within Firefox as the problem doesn't happen if I visit a site that I hadn't visited very recently. There's immediate response if I do that. I have DNS over HTTPS and secure DNS turned off in the settings, so it can't be those.

Anyone else have this problem? I wish there was some way to clear Firefox's DNS cache other than having to go into about:networking

I've lost all my open tabs....and I can see them in history, but when I open any historical item,...it loads it over the top of the only open tab I now have...as a result I only have one tab. Its a mess what have you done?

I have Firefox open. When I click on a link in Thunderbird instead of opening the page in the open Firefox window, it opens a second Firefox window? This just started happening and I don't know what I might have done to cause it. Using Windows 8.1.
