Thanks. The Mozilla documentation https://support.mozilla.org/en-US/kb/unload-inactive-tabs-save-system-memory-firefox is confusing. It says: "If you want to disable the Tab Unloading feature, you can set the preference browser.tabs.unloadOnLowMemory to false in the Firefox Configuration Editor (about:config page)." So I thought that it was true by default. -- Vincent Lefèvre <[email protected]> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / Pascaline project (LIP, ENS-Lyon)
