I just downloaded Firefox 3.6.6. & after restarting my computer all of the pages that I went to on the internet are now very small. I have a large monitor & had no problem with the previous version of Firefox. The web pages were all large. I know that you can click on "Ctrl +" to manually enlarge a page, but how do I adjust the settings so that all of the pages are large again? Help!!!
You can try to increase layout.css.devPixelsPerPx from 1.0 to 2 in 0.1 steps to see what works best.
This pref is a String value, parsed to a float, in Firefox 3.6.6 and allows to fine tune the dimensions of all elements more precisely.
To open the about:config page, type about:config in the location (address) bar and press the Enter key, just like you type the url of a website to open a website.
If you see a warning then you can confirm that you want to access that page.
