Am I the only one on the planet that never had stability nor speed problems with Firefox? (e.g. on Linux when I start Firefox it displays all tabs, but it refreshes/loads only the "last"/current tab - other tabs are refreshed/loaded only if I switch to them. On the other hand when I start Chrome, all tabs are refreshed/downloaded immediately, and all of them start running their code whatever it is)
