While Firefox suits me pretty good, it has a couple of issues that annoy a great deal out of me. The first one doesn’t happen all that often, but when it does, it annoys the big Jz out of me. The click with the middle mouse button anywhere on the page, except for the link. Usually, I use the middle button to open the link in a new tab. But if I miss the link, then Firefox uses whatever text was in the buffer as a new link for the current tab. I really hate that one, you know.
Today I accidentally discovered a fix. Simple, as usual. Navigate your browser to about:config and make sure that middlemouse.contentLoadURL is set to false. Tada! All done.
