A Firefox Add-on to simply center <body> by pushing a toolbar button.
There are some websites that have a left-aligned body of text that can be uncomfortable to read. If you haven't encountered any, some examples include homepages / blogs of some tech people I like to read and archives of mailing lists. I find it more comfortable to center them, and this add-on makes that process the push of a button. Maybe someone else gets some use out of it too.
On add-on site: Center Body.
Tested with Firefox 100.0.2 under Ubuntu (Linux).
When looking through the available add-ons I found one that does something similar: "Center Pages" (GitHub) (Add-on page) by Felix Meyer-Wolters (GitHub). It takes a different value-based approach, that is not exactly what I wanted to do. This is not an endorsement of that project, simply a mention.
