firefoxjavascript
On some pages I get the "Script not responding" error with an option to stop it and a checkbox to never ask again.
Later I get the same question again, with that pointless checkbox.
How do I make Firefox always stop a script when it's not responding?
Firefox is utilizing Domain guessing. It is an option that will automatically insert www or .com so that you don’t have to.
But, you don’t want that www., and there is a way to shut it off. The option to shut off domain guessing also requires shutting off keyword search for the changes to take place.
Changing Keyword search:
That is the Keyword Search part taken care of. Now to shutting off domain guessing.
In the search field, type fixup and double click on browser.fixup.alternate.enabled so that it will go to false.
All done, no more WWW or .com.

You can tell Firefox that you want it to stop automatically installing updates.
Use the "hamburger" menu (the three horizontal lines) in the upper right, then choose Options.
Then, in the General section, scroll down to the Firefox Updates section. Change to the Check for updates but let you choose to install them option:
While some have reported that this option has been removed, it still shows up in Firefox 81.0 (64-bit, Windows).
Other systems, perhaps where the system's own package manager is responsible for keeping Firefox up-to-date, do not show the option (screenshot is from a 64-bit Linux system):
Preventing software from being kept up-to-date is not a good security practice. It is strongly recommended that you let the updating mechanism do its thing. If you only update once a year, it is likely that more than just "your flow" will get broken.

You have to adjust
dom.max_script_run_timeinabout:configto higher value.As noted previously, this timeout also applies to add-ons using Javascript, as such it will be reached easily on slow computers using AdBlock, or even AJAX-rich websites like Google Docs etc.
