Personalmente non riscontro alcun problema, anche con un pc datato.
Firefox 26 and now 27 running in Ubuntu 12.04 have been very slow to open new pages - sometimes as long as 2 minutes. Chromium, on the other hand opened the same pages in less than 3 seconds. Using Wire Shark to analyze network traffic, we found that Firefox was querying the WINS name server a very large number of times number of times causing 300 ms delays in each query. (For some sites like the New York Times, there were more than 100 WINS queries.In the network configuration files, we found that WINS was listed before DNS in the list of name servers to query for looking up domain names. By editing /etc/nsswitch.conf to place WINS at the end of the name server list we were able to make Firefox open pages as fast as Chromium.To make this change, in a terminal typesudo gedit /etc/nsswitch.confenter the password and change the line that readshosts: files mdns4_minimal [NOTFOUND=return] wins dns mdns4to read as follows:hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4 winsSave the file and exit. Then reboot your computer. This will make WINS the last name server query for name lookup.
Type "about:config" in the address bar and press Enter.Search for "gfx.content.azure.backends".The value should be "direct2d,cairo". Edit it to be simply "direct2d" (ie. remove "cairo"), then restart Firefox.
