Since I disabled features in the people widget, I cannot access gmail

Question

I was so annoyed at the people widget covering up my emails that I disabled all the features IN it instead of the whole widget (which I have since learned how to do) and now I cannot access gmail with firefox. I can with internet explorer though, but prefer to use firefox.

Answer 1

-> Tap '''ALT''' key or press '''F10''' to show the Menu Bar
-> go to Help Menu -> select '''Restart with Add-ons Disabled'''
Firefox will close then it will open up with just basic Firefox. Now do this:
-> Update ALL your Firefox Plug-ins https://www.mozilla.com/en-US/plugincheck/
-> go to View Menu -> Toolbars -> unselect All Unwanted/Incompatible Toolbars
-> go to Tools Menu -> Clear Recent History -> '''Time range to clear: select "EVERYTHING"''' -> click Details (small arrow) button -> place Checkmarks on '''Cookies, Cache''' -> click '''Clear Now'''
-> go to Tools Menu -> Options -> General -> in '''Startup''' section click '''Reset to Default''' button
-> go to Tools Menu -> Options -> Content -> place Checkmarks on:
1) Block Pop-up windows 2) Load images automatically 3) Enable JavaScript
-> go to Tools Menu -> Options -> Security -> place Checkmarks on:
1) Warn me when sites try to install add-ons 2) Block reported attack sites 3) Block reported web forgeries 4) Remember Passwords for sites
-> go to Tools Menu -> Options -> Advanced -> Network -> Offline Storage (Cache): click '''Clear Now''' button
-> Click OK on Options window
-> click the Favicon on SearchBar -> click '''Manage Search Engines''' -> select all Unwanted Search Engines and click '''Remove''' -> click OK
-> go to Tools Menu -> Add-ons -> Extensions section -> REMOVE All Unwanted/Suspicious/Incompatible Extensions (Add-ons) -> Restart Firefox
-> go to Tools Menu -> Add-ons -> Appearance section -> REMOVE All Unwanted/Suspicious/Incompatible Themes (Persona) -> Restart Firefox
You can enable your Known & Trustworthy Add-ons and Themes later. Check and tell if its working.
