Prevent firefox load the thumbnail on new tab

Alessandro Martins

Hi. When a new tab is opened firefox tries to load the frequent sites as thumbnails, but if there's one offline i got a warning. FF is trying to load that site (that i know it is offline) without my intervention. I change operation system frequently and in another O.S. i know that site will be online, i do not want to remove it to prevent the warn, i want firefox stop to try load it on background. How to prevent firefox to load that thumbnail? I want him to load when I click on it. Already change these settings in about:config, none solve it:

browser.tabs.loadInBackground;false services.sync.engine.tabs;false services.sync.engineStatusChanged.tabs;false services.sync.prefs.sync.browser.tabs.warnOnOpen;false services.sync.prefs.sync.services.sync.syncedTabs.showRemoteIcons;false services.sync.syncedTabs.showRemoteIcons;false

New tab, new warning, that's so annoying. Thank you and sorry my bad english.

hi lopanrs, to generally disable the creation of cached thumbnails, enter about:config into the firefox location bar (confirm the info message in case it shows up). right-click somewhere in the page and create a new boolean preference named browser.pagethumbnails.capturing_disabled set to true.
