- Firefox Unable to Start: System Restore & XPCOM Loading Issue - Solutions Needed

Hello,

after restoring the system I can not start firefox. The message could not load xpcom appears. What to do?

Install FF again.

I am curious about the effects of this advice. I am just sitting at the computer with such a problem. This one has 32 bits in Widows Vista and, unfortunately, it can not absorb the ESR version of 64 bits, despite the fact that it has everything supposedly (internet advice).

@mczapski After all, the 64-bit program will not work under a 32-bit system.

So it's an interesting thing for me. Dell Studio 1737 with Vista. Nothing worked to run Firefox. It turns out that the user has unknowingly updated his browser to version 52. Now he misses a bit although he has IE and Chrome. Recently, for the sake of curiosity, we used the Acer with Win 7, which downloads Firefox 45 ESR and our delinquent at the same time claims that there is no such site (error 404). As I mentioned, it only gets version 52 but for 64 bit and completion known. We installed the Opera for holy peace.
