Firefox did an update yesterday and Firefox failed to launch correctly immediately after the update I uninstalled and reinstalled it three times and did multiple reboots to no avail. I also tried the fix for Ffirefox. No help. The program was unresponsive on start up and sometimes locked the computer. This started immediately after the automatic Firefox update was downloaded.
On launching Firefox there was a blank page and top left it said connecting, but it hung up there. The only icon or tab responsive was the close tab and when clicked, it would say Firefox is unresponsive. On clicking "end now", the screen came up to notify Microsoft about the problem.
I suspected I was not the only one with the problem, so I kept searching the Net. Last night some clever chap discovered the new update can leave Firefox exe running. If that happens, it behaves just like mine did.
The solution is to hold down Ctrl and Shift and press escape, while you are on the stalled page. That brings up task manager and you find Firefox exe and stop it manually Then hey presto the page connects and you have Firefox open and working normally. It has worked normally since.
I'm posting this in case any other members encounter this problem with a Firefox update.
Also I would be very interested if knowledgeable IT members could give me tips on how I could have isolated the problem. I was thinking that the update and new download was somehow corrupted.
Obviously I did not have the skills to run this down in a didactic manner. If I had them I would have not wasted so much time yesterday.
I had quite a correspondence with the Firefox Bugzilla people and they were completely obtuse and useless. I did post the solution for them on their site.
