I posted a (at least temporary) workaround for Firefox users here: https://www.gardenweb.com/discussions/5343325/use-alt-f4-to-close-all-the-windows#n=6  The gist of it:  about:config?filter=browser.link.open_newwindow - Set browser.link.open_newwindow to one - Set browser.link.open_newwindow.restriction to zero  Info obtained from: https://support.mozilla.org/en-US/questions/970999  It's possible you'll find changing the settings affects behavior on other sites and you'll not like it but it's every bit as easy to change them back. (Just right-click the preferences and select "reset". Even better than browser specific workarounds would be if/when Houzz fixes it... but in the meantime, one does what one has to do. :-) BTW, "alt F4" does not work for me. It closes every tab including the very last tab so Firefox closes down completely. Apparently it works for some though.

" ... Some users are reporting that they do not have the “hotfix-update-xpi-signing-intermediate-bug-1548973” study active in “about:studies”. Rather than using work-arounds, which can lead to issues later on, we strongly recommend that you continue to wait. If it’s possible for you to receive the hotfix, you should get it by 6am EDT, 24 hours after it was first released. For everyone else, we are working to ship a more permanent solution.

I tried the built-in Firefox Sync a long time ago but decided it wasn't for me. I don't remember why. On my home network I sync Firefox profile directories. I use a utility called rsync but it's not for everyone. Likely the easiest way is to use Firefox Sync but if you're comfortable with learning file locations, you can copy and paste either the entire Firefox profile or just the files you're interested in. For example, Firefox bookmarks are stored in a file called "places.sqlite". If you copy that file from one of your computers and paste it into another computer, you'll have your bookmarks from the first (master?) computer on the second (slave?) computer. Likewise, to copy the passwords remembered by Firefox, you just need to copy two files from the master computer/profile to the slave computer/profile. "key4.db" and "logins.json". Personally, I find it easier to copy the entire profile.. To locate your Firefox profile: https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data#w_how-do-i-find-my-profile A few of the important individual files: https://support.mozilla.org/en-US/kb/recovering-important-data-from-an-old-profile#w_your-important-data-and-their-files Possibly an added benefit of knowing where your Firefox profile is located is that you can make a "just in case" copy of it. I'm on Linux but on Vista I'm sure you can probably right-click the directory and select something like "Add to zip folder" or something like that? If your profile later gets corrupted you'll have a backup. Just unzip the backup and replace the corrupt profile.

I have for years set my browser home page for "blank" being that I'm always headed for one of a variety of specific web sites whenever I go online. I know the URLs or they're in my Bookmarks and I don't need something else to come up first
