I have tried uninstalling and reinstalling Firefox 36, creating a new profile and resetting FF firewall permissions in NIS, all with no effect.

A new Firefox profile doesn't help ?
The only way to proceed would be that you find the regression range (first bad build) because I can not reproduce your issue and we have no other reports.

Are you willing to install our mozregression tool to find the first bad build ?

Thank you, Matthias. I am perfectly happy to install the tool.

Please first test a nightly build: https://nightly.mozilla.org/ 
You want the 32bit one as all release builds on windows are 32bit.

I have tried both 32-bit and 64-bit versions of Nightly and both open in < 6 seconds.

Can you please also try the Firefox (37) beta : https://www.mozilla.org/de/firefox/channel/

Comment 7

[smcc]

FF 37 beta takes > 10 seconds to open.

Comment 8

[Matthias Versen [:Matti]]

Is Firevfox37 ok or slow as Firefox36 ?
"> 10 seconds" ~ "10 seconds" (comment#0)

Comment 9

[smcc]

FF 36 takes up to 60 seconds to open. FF 37 is a good deal faster but slower than Nightly,which opens in 3-4 seconds.

[Matthias Versen [:Matti]]

I thought that the issue is caused by one change in the source code but it seems that it's not true.
Finding a regression with our tool is therefore probably impossible :-(

Hello, again. After update to version 36.0.1  on 6 March Firefox startup speeded dramatically and I thought "Good. The problem has been solved". I had 2 weeks of happiness with a startup time of a few seconds.Unfortunately when I updated to version to 36.0.3 on 21 March startup deteriorated to 60 seconds. Today a further update to 36.0.4 has made no difference to the startup time. Nothing else on the PC has changed and there is no sign of malware

Please, please, please can someone help?

Hi smcc, 

Sorry for the long wait on response. Try updating to Firefox 43. Are you still having this issue?

Hello. As you are aware Firefox has gone through several re-incarnations since I first had my problem. I can't rmemember which version rectified the problem but it is now running very quickly.
