My biggest gripe with Firefox is how it opens tabs. If I open a new tab in Chrome, it opens just to the right of the current one which is nice because it keeps related tabs together. In Firefox it opens to the far right which is annoying. I tried installing an extension to fix this but it was buggy. Only recently did I discover that I could dig into about:config to enable the behavior I consider expected (and I'm sure most people agree with me given how many Chrome users there are).

I already updated to v.72 so I don't know if they changed the default, never really noticed before. But now

  browser.tabs.insertRelatedAfterCurrent

defaults to 'true'. I agree this is expected behavior :)

FF71 - default is also true.

Edit - default for this config variable could be platform specific; the above is based on Windows 10. I'll check on my MacBook tonight.

That only applies when you open a tab by clicking on a link. If you do ctrl+t, you'll get new tab at the far right.

Damn, another option I need to change when I upgrade Firefox. :( I liked the old default. I think I will have to start writing a user.js.
