I made the size so small I can't read anything

I was attempting to reduce the size of the tab bar using about:config and I screwed up making everything so small I can't determine where the setting is to change it back. What can I do to get it back to normal, preferably without losing all my shortcuts?

Chosen solution

I was able to resolve the issue by using the magnifier tool in Windows to place my cursor over the search box at the top of the configuration page and type layout.css.devPixelsPerPx enabling me to change the value back to -1.0. Unfortunately, that still means the tab bar is far too large, but at least I can still use Firefox. I tried several other values, some did nothing at all, while others made the text too small. I'm not very happy with this latest update v103.0.
