Since yesterday I observe some strange behavior of my Firefox 5 browser. Two of my extensions stopped working:
Both add-ons worked before and used to display some dialog box for bookmarking / sharing. Now nothing happens when trying to invoke these add-ons.
Besides Firebug 1.8.0 does not seem to work as well; I can’t find any means to enable / start it, there is for instance no icon showing up in the Add-On Toolbar, even after trying this recommendation.
The weird thing is: after I tried to use any of the two extensions mentioned above the Tools –> Add-ons feature in Firefox stops working as well: no add-ons page is displayed anymore.
And: after exiting Firefox it stays in memory ( I can see the process in Windows Task Manager ) and thus I can not re-start it without first killing that process.
Time of switch to Google Chrome as my default browser like many others are doing it these days ? Or does anyone have any idea how I can debug, investigate, mitigate or solve these problems ?
