I don't understand scrolling down. Isn't Open Link in a New Tab the very first choice on the context menu that appear when you right-click a link?

Other ways to open a link in a new tab include:

• Ctrl+click
• middle-mouse-click (scroll-wheel-click)

If you install the Tab Mix Plus add-on, you can force all links to open in a new tab when you left-click. (Screen shot with settings: https://support.mozilla.org/en-US/que.../935121#answer-361552)

Of course, if you want to read the source code of Firefox, it's available online. And much of it can be "hacked" on your PC by opening a JAR archive using an unzip utility, editing, and zipping it back up. But that's only good until the next update, so...

A ctrl+click as the default option for left-click would be acceptable, but the proper tab handling process as in Netscape is what I'm looking for. If I had 3 tabs open and the 2nd one was current, I want to left-click a link and have it open a new tab between the original 3rd and 4th tab and open that link in what is now the 3rd of 4 tabs open. My question is what module has the deficient code for me to change? I realize that I will have to update it with each new version but hopefully it will be fixed one of these days. I had to change code for a bug in a module for several 3.x versions but it was fixed by 4.x. Thanks in advance.

I'm not sure anyone here can answer your question without searching the code. (Support folks, not developers.)

Tab Mix Plus did not work. I removed it and installed Tab Utilities 1.1.5 which does work acceptably. It opens a new tab to the right of all open tabs. I also found the tabs code in a UserChrome module in the Chrome folder that may fix it without a plugin. Thanks.
