Google Wont sign in Laptop. [Mac.]

[kevs]

In FF, not other browsers, and just on laptop, not desktop.

I go to Google homepage, click sign in, and click ok list 5-6 account I have, but click does not work.

Click does work for any clickable links, sign in, use another account, add account, nothing. Exasperated, thanks@

Try running in Firefox "Safe Mode".
> http://kb.mozillazine.org/Safe_Mode
or... Help > Re-start with Addons disabled or hold down your Shift key as you click the Firefox short cut..
Do not check any boxes.
This is a fault finding mode.
NB: Be careful of the "Delete all bookmarks except for back-ups" option.

Don't add any extensions or themes until it's working O.K.
If Firefox is O.K. in Safe Mode then it's possibly an extension/theme...etc causing it.
Run Firefox in normal mode & disable them all. Re-start Firefox.
Enable each in turn, or by ½'s, re-starting Firefox each time, till the faulty extension is found.
Either update or un-install it.

See this incomplete list,
> http://kb.mozillazine.org/Problematic_extensions

When in Safe Mode...
* The status of plug-ins is not affected.
* Custom preferences are not affected.
* All extensions are disabled.
* The default theme is used, without a persona.
* userChrome.css and userContent.css are ignored.
* The JIT/Javascript compiler is disabled.
* The default toolbar layout is used.
* Hardware acceleration is disabled.
