Another update: The issue keeps repeating even with full format of the system and just installing FF6 straight up.

No problems found on the hard drives, and today, I started FF and it updated to 6.0.1 and it froze while loading "what's new in firefox" page on startup even. - Image

Also, I've noticed that every time I start firefox, in about roughly 5 seconds it freezes always when I start using it (load some page or something). Nomatter if I am loading any new page or not. I've done everything that was suggested here and yet the problem continues to exist.

When firefox freezes, I can try to force close or wait for it to respond. The details are following:

Hello,

thanks for your reply. I did check my plugins before but now re-checked and they are all up-to-date as seen here.

The problem still persists.

Check and tell if its working.

Change the connections setting.

This problem became more evident in Firefox 7 and was fixed in Firefox 8. It causes problems sometimes on Window systems, including failure to complete loading and hangs.

• firefox never finishes loading certain websites_lower-the-max-number-of-http-connections

The workaround is fairly quick and simple and so worth a try.

@John99: I don't have problem with infinite loading though. I anyway tried your suggestion but no luck.

@mha007: Tried everything 1 by 1 but nothing could indicate from that list what is freezing firefox still. I even formatted my Laptop recently and just installed Firefox (7 and 8) and it still happens on fresh installations on Windows 7 64.

Hi gain frejm,
A few more ideas for your consideration

• hangs due to bookmarks database
  There is a problem causing hangs that is now fixed on Firefox 8 but not in Firefox 7 or earlier. It relates to the maintenance and use of places.sqlite the file that holds History and Bookmarks. There is an add-on that can be used to fix this problem
  • try the add-on see http://blog.bonardo.net/2011/09/30/is-your-firefor-freezing-at-regular-intervals
• what version of firefox are you currently using?
  the system info from when you started the thread shows fx6, you should be on fx7 by now, in fact I would suggest you in fact change over to the beta channel so as to get firefox 8, that seems stable and has solved some of the fx7 problems

I will try to sumarise my understanding of a few of the facts, correct me if I am wrong.

• problem is hangs or freezes of firefox (as opposed to crashes with crash info showing)
• you have
  • scanned for malware
  • tried in safe mode, including also then disabling all plugins
  • tried reducing the max connections preference
  • you checked your firewall is not blocking anything

Some more questions

• what security software and firewalls (including add blockers and any sytem software) are you currently using. (sometimes different products may interact badly)
• how often and when does it hang, are you noticing any patern
  • if it hangs downloading and then loading almost any web page I suggest you try
  • save a web page to the local system drive, then try opening that saved copy,

does that work ok

• try looking at your error console is that mainly clear of errors ?
  • use Firefox Button -> Web Developer -> Error Console
    1. clear all the errors
    2. try loading pages from this forum, does it remain clear of errors
       (It is probably fairly normal to see a variety of errors an a lot of sites, using this forum should be error free)
  • there is also the possibility of trying to log gc & cc collections in the error console, which could be informative, at least to the developers
• Try using IE or some other browser, does that work ok ?
• have you tried firefox in a new clean profile yet ?

There probably are a few unknown causes of hangs at present judging by the number of posts, it may be worth filing a formal bug about your problem if it occurs in safe mode with a recent supported release of firefox, if you are interested in making that effort please let me know.
