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

disable javascript
in `about:config` disable `javascript.enabled`
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

But in order to fine-tune them, it is necessary for user to have a master's degree in computer science.

Hi Clayten,
While this may not be exactly what you're looking for, it's a different approach. Assuming that you're opening these new tabs in the background, the following add-on will prevent the content from loading until you actually click on the tab: https://addons.mozilla.org/firefox/addon/loadtabonselect/
NOTE: I haven't tried it myself.
I hope that helps.
