Automatically stop "A web page is slowing down your browser"

已張貼

I don't care [to take the time to find out] what's causing it; I just want to stop it. I always click "Stop it". Now I just want to avoid ever seeing it, or it would be ok to see the message for a second or so but then have FF click "Stop it".

Thank you

I knew that. As I said, I just want to stop it. The webpage you cite doesn't begin to address my issue. Thanks anyway.

Hello ral,

Would you try this please :

Type in the address bar about:config and press Enter (promise to be careful, if asked)

Type in the search bar dom.ipc.process

and look for the preference dom.ipc.processHangMonitor

Set its value to false

Then type in the search bar and look for the preference :

dom.ipc.reportProcessHangs

and set its value also to false

Then close and restart Firefox.

Shouldn't that help you to get rid of the nuisance; then change the values back.

I hope it does the trick though ....

Thank you McCoy! It looks right and I'm going to mark "solved". If it does work, I'll never know.

Well, it stopped the "A web page is slowing down your browser" message, but now I'm back to the "A script on this page has stopped working" message. In either case I am stopped from proceeding until I click on something. So I still have essentially the same problem. The next time it happens I will note the exact wording and probably post a new question. I guess this is progress, so

Thank you very much, Robert Leeper

Would you please (for now) disable your Video DownloadHelper extension, to see if that will make a difference ?

If that's not it; would you try this on the "about:config" page and type in the search bar :

dom.max_script_run_time and change its value to 30

then close and restart Firefox.

Any luck ?

Thank you very much, McCoy. I will try it/them.

For testing purposes it would be extremely useful to have a page that is known to have a script that stalls frequently. Do you know of such?

Thanks again. Robert

Note that it is probably not a good idea to disable the hang monitor (dom.ipc.processHangMonitor = false). This includes hangs in the plugin-container process used by Flash to control what happens if the plugin doesn't respond (IPC=Inter-Process Communication). If you disable all hangs then you can block Firefox and would have to kill the process or wait a long time.

You can read the comments in the Firefox source code.
