Re: [Question #12326]: Firefox frequently freezing

 

Question #12326 on firefox in ubuntu changed:
https://answers.launchpad.net/ubuntu/+source/firefox/+question/12326

powertower proposed the following answer:
I've posted this on an ubuntu thread also but here goes:

OK so I've been fighting this problem for several weeks. No one seemed
to know why firefox would freeze in Ubuntu 8 and 9. I figured it out by
running firefox in debug mode. "NSPR_LOG_MODULES=all:5 firefox"

Every time firefox froze I would see "resolving safebrowsing-
cache.google.com". So I tried the usual ping, nslookup and the results
were very inconsistent. Sometimes it would resolve but mostly just time
out.


After a little googling I found out that firefox has built in Google Safe Search that frequently communicates with safebrowsing-cache.google.com.

So I disabled this safe search feature and NO MORE LOCK UPS!!

You can disable This safe search feature by going to Edit - Preferences
- Security, uncheck "Block reported attack sites" and "Block reported
web forgeries" .

Hope this helps some of you, it was very frustrating for me.
