how to stop all tabs? "Offline mode" does not stop connection attempts

Posted

tell me who knows, how to stop all tabs? Even when I enable the "offline mode", tabs with heavy javascript continue trying to load, consuming CPU resources. I want they to stop immideately. I tried different extensions, but results are unsatisfactory. Does anybody know some trick? My goal is to find a method to flush all javascript structures in RAM. I explored about:memory, and tried the vmmap.exe (process memory analyzer) from the Sysinternals Suite, but I have not succeeded so far. Auto unload tab -- is not a solution. For example I clicked on links and opened 30 tabs in background. PC starts working very slow, Now I want to stop all them, and to read the loaded information (webpages). How to do it? I think it is the weakest side of Firefox. Needed to abrupt all attempts to make network connection, after the "offline mode" is enabled. I need something to stop javascript's attempts to connect, to calm it down. I want to start read webpages already loaded, and javascript occupies CPU. To kill threads in the Process Manager is not a way to do at all, Auto-unload also, I want to read those webpages. I have enough of RAM, it is not used more then a half. Many years ago, when there was HTML4, I used for a little the Maxton browser. It had a button to stop all pages. All similiar Firefox extensions do not act effectively like that. the issue not in scarcity of RAM, but in a badly design of browser's architecture, that javascript occupies users' PCs.

You likely already tried these but just in case... Have you tried these two extensions?

https://addons.mozilla.org/en-US/firefox/addon/superstop/?src=search

and

https://addons.mozilla.org/en-US/firefox/addon/stop-all-button/?src=search

There's also this that might have some useful information

https://support.mozilla.org/en-US/kb/how-stop-firefox-making-automatic-connections?redirectlocale=en-US&redirectslug=how-stop-firefox-automatically-making-connections

I'm researching this.

You want to kill all connections and prevent javascript from continually trying to load on all tabs at will, right?

Your post is not helpful. I came to conclusion that, such to say, user-level methods (extensions etc) do not work. It is needed some trick with virtual memory - to empty working set or something.

To flush all javascript structures from the memory heap, that only the loaded html must be displayed in tabs, without javascript ride on CPU.

I want not to stop auto-reload (auto-refresh) attemps, such webpages are rare, even when they try json requests, it isn't a problem. I mean to stop javascript to make any calculations on CPU after I enable the offline mode. As I wrote, it is a weak side of Firefox.

You did not understand what I wrote. Javascript is necessary to display the webpages correctly. And it is needed to be halted aftewards, not to do any work in RAM. dom.always_stop_slow_scripts is not a solution either
