title:Firefox maximize windows fullscreen and config description:How to default firefox to full screen maximized windows, and how to use the about:config interface with KDE. Link to Firefox font config. keywords:firefox,mozilla,chrome,browser,full,screen,max,maximize,maximized,window,windows,drag,save,auto,default,automatic,kde,manager For more details about Firefox fonts, see: http://defindit.com/readme_files/fedora_kde_config_setup.html It appears that the modern way to control user font settings is via .css files in the applications preferences directory for each application. Find and change most Firefox internal config values: about:config This allows you to double click to modify, or right click for more options. Crude and geeky, but seems to work. However, some (all?) settings found in localstore.rdf are not configureable from about:config. I don't know what changed but the trick to getting Firefox to maximize browser windows all the time: - resize window. I used right-click in title bar, and then resize. Resizing by dragging a window border may also work. ( - Maximize window with the maximize button. - Exit Firefox (so it saves it's current state). When I restarted Firefox after this, it was maximized, and all new browser windows are maximized. Prior to doing this, I couldn't find any setting that would make Firefox open maximized, and new browser windows always opened at the same size as the browser when it first launched. As far as I can tell, this behavior is undocumented. At least searching Google for quite a long time with all kinds of combinations of keywords didn't turn up anything interesting (granted that I never go beyond the 3 page of results). This all applies to KDE. I couldn't find a KDE setting to maximize one application's windows. I'm guessing that some of the KDE window arcana could do this, but it isn't documented, and even if it was, the docs would have to describe Firefox's windows class properties. Besides, I don't want all Firefox windows maximized, only the browsers.
