I thought I'd try Firefox again, again. Wanting to get as current as possible, I downloaded Firefox 3.5 beta 4. I haven't had a bit of trouble from the beta.
Most of the Add-ons I'd used before are still valid with Firefox 3.5 beta 4. Only Tab Clicking Options wouldn't work with it. This was easily replaced with Close Tab by Double Click. You don't even have to set any options. On QuickDrag I also checked "Open tabs for text searches in the foreground."
Besides the previous tweaks, I also found one to make search results open in a new tab.
Type about:config into the address bar, and then put the following into the filter box:This time, I also turned off third party cookies.
Double-click the value to change it to true.
So far, so good.
