CTRL+0 (<--that is a zero) will reset your zoom level on affected pages. Firefox remembers the zoom level you last used on a page.<br /> See Firefox built-in Zoom functions: *http://support.mozilla.com/en-US/kb/Page+Zoom *http://support.mozilla.com/en-US/kb/Text+Zoom If that does not fix the problem, you can try renaming the file (''with Firefox closed; Firefox button > Exit or File > Exit'') '''''content-prefs.sqlite''''' to content-prefs.sqlite.old (or delete the file) in the Profile Folder to reset the page zoom on '''''all''''' sites. That file will be re-created when you restart Firefox. *http://kb.mozillazine.org/Profile_folder_-_Firefox *You can use the button to go to the Firefox profile folder: **Help > Troubleshooting Information > Profile Directory: Open Containing Folder Zoom Add-ons: *'''''Default FullZoom Level''''': https://addons.mozilla.org/en-US/firefox/addon/default-fullzoom-level/ ''''' *'''''NoSquint''''': https://addons.mozilla.org/en-US/firefox/addon/nosquint/ **More info on NoSquint: http://urandom.ca/nosquint/ '''If this reply solves your problem, please click "Solved It" next to this reply when <u>signed-in</u> to the forum.''' ------------------------- Not related to your question, but...

Also, please check if '''Allow pages to choose their own fonts, instead of my selections above''' is enabled in '''Tools''' ('''Alt''' + '''T''') > '''Options''' > '''Content''' > '''Advanced''' (in '''Fonts & Colors'''). If the screen resolution is big, you can also try to set a '''Minimum font size''' here, for eg. 16. [https://support.mozilla.org/en-US/kb/Options%20window%20-%20Content%20panel?as=u#fonts_and_colors Options > Content] If you previously set the zoom for the sites you can '''Reset''' the saved preference of individual sites by pressing '''Ctrl''' + '''0''' (zero). [https://support.mozilla.com/en-US/kb/Page+Zoom Page Zoom]

Be aware that increasing the minimum font can cause issues with text overlapping on sites that position text absolutely or text disappears (gets hidden), so the preferred way is to use an extension.
