How do I fix Javascript message that says "too much recursion"?

Question

Hi there, every time that I load up or refresh a webpage in Firefox, I'm getting a message popup from Javascript that says "too much recursion" - I have no idea what this means or how to fix it, but it's gotten to a point where it's making it almost impossible to do anything through Firefox as it's popping up so often. Is there a way to make this stop?

Hello lavendermoon, maybe an installed Extension that have problems with their JavaScript is the issue, to check that '''Try Firefox Safe Mode''' to see if the problem goes away. [[Troubleshoot Firefox issues using Safe Mode|Firefox Safe Mode]] is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes).
If Firefox is open, you can restart in Firefox Safe Mode from the Help menu:
*In Firefox 29.0 and above, click the menu button [[Image:New Fx Menu]], click Help [[Image:Help-29]] and select ''Restart with Add-ons Disabled''.
*In previous Firefox versions, click on the Firefox button at the top left of the Firefox window and click on ''Help'' (or click on ''Help'' in the Menu bar, if you don't have a Firefox button) then click on ''Restart with Add-ons Disabled''.
If Firefox is not running, you can start Firefox in Safe Mode as follows:
* On Windows: Hold the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* On Mac: Hold the '''option''' key while starting Firefox.
* On Linux: Quit Firefox, go to your Terminal and run ''firefox -safe-mode'' <br>(you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
When the Firefox Safe Mode window appears, select "Start in Safe Mode".

'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, theme, or hardware acceleration. Please follow the steps in the [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]] article to find the cause.
''To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
also try to delete in your [http://kb.mozillazine.org/Profile_folder_-_Firefox#Windows profile folder] the [http://kb.mozillazine.org/User.js_file User.js file] you have.
The user.js file does not exist by default. If you create the file, forget it, if you have not create the file then delete the User.js file, to see if the problem goes away (some programs create and write in the file also).
thank you
