A Hacking trick to Reset Zoom option to normal level on Firefox
Firefox provides zoom options on all web pages by using either combination keys Ctrl + keys to zoom in and Ctrl – keys to zoom out or by using commands from View –> Zoom menu. The zoom features on Firefox3 help in magnifying or reducing text and image sizes.
Firefox3 also remembers the last zoom level for every domain used previously. It automatically opens any webpage from its domain with the previously used zoom level. Its like if you had used zoom in option on Gmail.com to increase the text and image size, then next time you open Gmail.com, Firefox3 remembers the zoom option and opens Gmail with the previously set zoom in option.
Sometimes the user wishes to temporarily use zoom option for a particular page and will not want the zoom option to be made available for all subsequent use of the related pages from the domain.
To display the zoomed in page with normal zoom for subsequent use can be done using a hacking trick. One has to type in the Location Bar about:config and then locate a preference name called ‘browser.zoom.siteSpecific‘. After this one needs to open this preference and change the value from true to false.
If all the above hacking steps are followed sequentially, then every new page on Firefox browser is made available with normal zoom.
