Pokušaj da reinstaliraš FF!

Restartuj.

Sve sam to i pokusao pre nego sam se i obratio ovde za pomoc, ali nista nije pomoglo.

Software installation disabled

In Firefox 1.0.x the option to allow web sites to install software is found under "Tools -> Options -> Web Features -> Allow web sites to install software". Starting in Firefox 1.5 the option has been removed from the user interface (UI). The software installation option must be enabled to allow installation of themes, extensions and certain plugins that use the XPInstall method.

If you click a web site's "Install" link and you see a message bar that says "Software installation is currently disabled. Click Edit Options... to enable it and try again.",

* Firefox 1.0.x: Click the "Edit Options" button to open the Web Features preferences panel, place a checkmark in front of "Allow web sites to install software" and try again.
* Firefox 1.5: If you previously disabled this option and then updated to Firefox 1.5, the disabled setting will be carried over. Since the option to enable software installation no longer exists in the UI, you will need to use about:config to reset the "xpinstall.enabled" preference to the default "true" value (bug 310737). Here's step by step how to do this: Type about:config to Location Bar and hit enter. Type xpi to filter and find xpinstall.enabled. Make sure it's value is true. (double click will toggle). Now you should be able to install.

Hvala callex, ovo je resilo problem!

Pozdrav.

pozdrav

i ja imam isti problem ali nisam upeo da ga resim...:(
jel moze malo detaljnije i prostije (nisam bas neki haker :) ) objasnjenje za ovaj postupak u predzadnjem postu kako to uraditi?

pozdrav i cujemo se

Ne detaljnije nego kraće, probaj konkretno ovaj deo:

Type about:config to Location Bar and hit enter. Type xpi to filter and find xpinstall.enabled. Make sure it's value is true. (double click will toggle). Now you should be able to install.

hvala druze na izdvajanju tri recenice iz teksta od deset recenica mada nisi morao, i sam sam shvatio da je u tom delu resenje. zato sam i pitao moze li malo detaljnije i na SRPSKOM posto se solidno snalazim sa engleskim ali ne razumem gde upisati config (location bar ? )
ako mozes ovo malo da mi pojasnis bilo bi dobro ...

reseno...
resio sam problem tako sto sam u google ukucao location bar i negde je pisalo da je to ustvari adress bar (kako ja znam da se zove ).sve sam uradio dalje kako pise i problem je resen.

pozdrav
