Can I have 2 completely different set ups for FF (different users--one visually impaired)

I have been using FF for several years and really like the way I can enlarge the text and size of the fonts on the toolbars, among other things. My wife, however, has very limited vision, and has been using IE and she cannot do any of that and she has been having other IE problems as well. I just installed Chrome to check it out, and there does not seem to be a way to do any of that either (too bad Chrome). There are 'high contrast' themes, but they do not do enough, or are the wrong colors, or cause lots of problems with some pages. Is there a way I can use 2 completely separate versions of FF, with different tool bars, screen fonts, colors for the toolbars, sizes of the fonts, a way to have 2 completely separate bookmark and preference lists, etc.? As the computer is shared, we would need to be able to toggle between users and the set-ups. The ability to configure FF the way you want is really so far ahead of the other browsers.

You can create another Firefox profile folder for your wife if you both use the same Windows account.

See also:

You can add -no-remote to the command line to open another Firefox instance with its own profile and run multiple Firefox instances simultaneously.

Note that you can't open external links (i.e. click a link to open the default browser) in a Firefox instance that is started with the -no-remote command line switch.


You can look at this extension to adjust the font size for the user interface.

You can use the NoSquint extension to set font size (text/page zoom) and text color on web pages.
