WHy can I no longer open multiple tabs; whenever I try each tab is opened but no page is downloaded but no error messages are displayed
Each tab displays the usual rotational 'downloading' icon but even if I wait several minutes nothing happens.....
Even if I halt all or close all tabs bar one I am no longer able to download any pages unless I close Firefox completely and restart.
Upon restart I can then open tabs slowly one at a time but if more than one of my open tabs tries to update similtaneously then the problem reoccurs and I have to restart Firefox once again.
I have tried removing & reinstalling Firefox as well as creating an all new profile (importing only bookmarks) with no change

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
- Don't make any changes on the Safe mode start window.
