525822 - stalls on startup (extremely slow) when loading tabs

Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

Description

[Liutger Franzen]

User-Agent:       Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; SLCC1; .NET CLR 2.0.50727; Media Center PC 5.0; .NET CLR 3.5.30729; .NET CLR 3.0.30618)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.0; de; rv:1.9.1.4) Gecko/20091016 Firefox/3.5.4 (.NET CLR 3.5.30729)

After automatic update from 3.5.3 to 3.5.4, Firefox loads the tabs on startup extremely slow (takes several minutes).

Reproducible: Always

Steps to Reproduce:
1. Start Firefox
Actual Results:  
Firefox loads tabs, but EXTREMELY slow: first it shows in the status line that it trys to resolve the host name after quite a while that it connects to the host name.

Expected Results:  
Normal startup with normal load of tabs like before the update.

I've tried the following to resolve or identify the cause of the problem:
- disabled avast! virus scanner
- disabled PC Tools Threatfire
- disabled all Addons
- started with a different, freshly created profile
- installed 3.6a1
None of these tries changed the startup time.
Things were totally ok before the update and surfing with other browser (e.g. Internet Explorer 7.0) works without a problem.

Tried to uninstall (incl. deleting the profiles) and reinstall 3.5.4 with the same results.

Uninstalled again and installed version 3.5 with worked without any problems.

Updated from 3.5 to 3.5.5 and problem did not occur again. Can someone confirm the original bug? Possible causes?
