Profile manager and import settings and data hang on firefox 42 to 43.0b2
since I updated to firefox 42 or the beta versions that follow until 43.0b2 which is the last version until this moment, the first run of firefox doesn't show anything, just the process running in the background. One of my trials to install showed me the importing window but it was blank and the it was stuck. the second run firefox works but if I try to open the profile manager "firefox.exe -p" it doesn't run or it shows the profile manager window blank. I downgraded to firefox 41 and it works fine but if I upgrade again it's the same problems.
(I did this on a clean install of windows 7, I reinstalled windows because I thought I messed up but the problem persisted, so it's certainly a problem with the lastest versions of Firefox)
Update : I wasn't able to reproduce the problem today, it seems that I can open the profile manager. I don't know the exact reason for the problem to get fixed. The only change I did is that I installed all windows updates.

Could have been a driver update with the windows patch?
It is possible that your firewall or other security software blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full, unrestricted, access to install for Firefox and the plugin-container process and the updater process.
