Here's the problem, really two problems:

I used about:config to fix the layout.css.devPixelsPerPx (As you answered to another's question recently). I messed it up, I was even warned on the screen. Instead of 1.0 for the Pixels per Px, I put in .05. An idiot thing to do, I know!!! So now my text is literally UNREADABLE, it's even too small to see it zoomed in all the way, so I couldn't see the text in the about:config list to fix it! I tried it several times, but I couldn't read it one bit. So I tried uninstalling keeping all my old info, and it came back up the same! What should I do?

hello Miraclesnow, you can perform the following steps to change the value again "blindly":

  1. open firefox and press ctrl +L (this will put the focus into the location bar)
  2. type about:config
  3. press enter twice
  4. type devpix
  5. press the tab key
  6. press enter
  7. type 1.0
  8. press enter again & hopefully you should be back to normal visibility now

Thank you! I think it fixed it for me- I also made sure to get rid of any old settings or changes I made on it, just in case.

How do I post a different question about the about:config? That looks funny! But I have question re: the bold vs italic entries. Thank you.

Hi JannEd

Could you please start a new thread?

Then you can provide more information like your operating system and installed extensions and installed plugins.

Are you talking about how pref look on the about:config page?

Prefs that haven't been modified are in normal text and show "default" in the Status column.
Prefs that have been modified from the default are displayed in bold and show "user set" in the Status column.
Prefs in italic are locked prefs that can't be modified.

See:

These functions can be used in the mozilla.cfg file: 

defaultPref();  // set new default value
pref();         // set pref, but allow changes in current session
lockPref();     // lock pref, disallow changes
