The problem that i had earlier (from here: https://support.mozilla.org/en-US/questions/1078544#answer-769701) has returned. This time, the solution doesnt work anymore.

Pasted text from last time: [ After the last update (40.0.2 @ 13.08.2015) Firefox just wont open. The process comes visible in task manager, but does nothing. no window. JUST. NOTHING. It only functions in either safe mode or when ran as an administrator. I tried all other computers in the house too. Same thing. ]

The difference this time and the reason the solution wont work, is that uninstall takes the mozilla folder with it, so i cant delete it. After reinstall, it gives you an option to start firefox now - so it does, but after closing the problem returns so every time i want to use firefox i have to reinstall it. If i refuse the option of starting it now, the problem becomes immediate.

So i hear that microsoft has a new browser, is it any good?

I understand that the previous work around was to remove the data before a reinstall. I am happy to help.

It is possible to "remove" the file by putting it somewhere else before a reinstall, or I might suggest to change a new profile by starting Firefox with the profile manager:
