[Bug 1870450] Re: Firefox takes a moment before being reactive after launch

[Olivier Tilloy]

** Description changed:

+ Description from duplicate bug report:
+ 
+ Hi,
+ 
+ on a freshly installed Ubuntu Budgie 19.10, I've noticed Firefox is kind of slow at start :
+ ⋅ I can launch Firefox but it’s unresponsive for a moment ( no blinking cursor anywhere )
+ ⋅ then cursor eventually appears in address bar but blinking slowly and not usable,
+ ⋅ still, clicking anywhere has no effect, or effect delayed much later,
+ ⋅ a moment later, cursor blinks at its usual pace and Firefox becomes responsive as expected.
+ The whole process takes 30 seconds to 1 minute and Firefox runs rather ok later on with some slow moments though ( sometimes tabs are slow to react, or any interactions with buttons in FF menu ).
+ 
+ Same behavior in safe-mode ( without any FF addons )
+ 
+ Same without any Budgie applets regarding app-menu ( such as pixel-saver
+ or global-menu applets ).
+ 
+ see also :
+ ⋅ https://discourse.ubuntubudgie.org/t/firefox-in-19-10-is-kind-of-slow-to-start/3265
