Tried all troubleshooting, Firefox still doesn't load pages
***************************** The problem When I start firefox I see a blank page (this was not my starting page before the problem occured)(Image linked).
The overall graphical window is not frozen but I can't open any webpage nor any local file. The option pages don't work either nor any of the about:XXX pages.
*************************** What I tired I cleared my cookie/cache. I tried firefox's safe mode. I refreshed firefox. I deleted my profile and created a new profile. I desactivated all my security software. I ran firefox with root privilege. Updated windows. None of that did solved the problem.
This problem persisted after I haved uninstalled Firefox, deleted my profile, deleted all mozilla directories in ProgramData, AppData, Program, cleaned up my disk with window's 10 utilitary and reinstalled firefox (I also tried a simple install unistall so I don't think I broke firefox by deleting files). When reinstalling firefox I tried both a 64 and a 32 bits install with current and older version none worked.
I scanned my PC for malwares, nothing found. I checked my memory as suggested in a troobleshooting page, (no problem found).
Firefox DOES WORKS in window's safe mode.
************************************ Observations I noticed via my firewall that firefox don't even send any package to the internet if I try to acess a website. Firefox does however acces 127.0.0.1 (at least it asks for permission). Firefox doesn't close if I use top right red cross, it does close if, in task bar I right click/close all windows or if I exit within the "three horizontal bar menu" I precise that my connection is ok and that MS Edge is working fine.
I repeat, Firefox works in window's safe mode.
I would really appreciate your help as I can't find any other thing to try.

I understand that deactivating my security software would be the most logical advice, but this is among the first things I tried and it didn't solve the problem. However, your answer made me think that another program could interfere with Firefox.
So I deleted all my HIPS* rules and it works.
To explain, if anyone is interested, a still unknown to this day program was interfering with Firefox and causing trouble. This was allowed because I (by misjudgment) allowed this program to perform an action it shouldn't. By deleting all my HIPS rules the operations of the unknown program were blocked and Firefox works again. (Obviously, if no rule applies the action is blocked).
Takeaway: If you don't have a security software that does HIPS rules management: get one. (I personally use Comodo firewall, it's free) If you already have one check that all your rules are legitimate.

Start your Computer in safe mode with network support. Then start Firefox. Try Secure websites. Is the problem still there?

Hello, Thanks for answering. I can surf the web in window's safe mode, the problem is 'resolved' in safe mode.
Additionnally : I made sure all my drivers related to network where up to date. I noticed that the Firefox's profiles of the others local accounts were not deleted by all the manipulations I did. So I deleted them but that didn't change anything. I fetched the info on the about:support page, here's a google doc in case you want to look at it: https://docs.google.com/document/d/1yUg2DMdblcPNXQtKsnhOmosTzUWoIrEnFyrbCgPttS4/edit?usp=sharing

So maye be I'll repeat what I said. Firefox works in safe mode, I have updated my drivers, I can get the about:tsupport page if that helps
Thanks again for your time
Sorry, current forum security sometimes delays the posting of messages. And in turn, we are not notified of those posts.
If Windows Safe Mode causes no issues, then another program on your system is the issue. As a test, disable your protection programs.

As a side note, even if this problem is quite advanced/rare you might want to make this problem and it's solution more visible as I couldn't find anything similar on the offical support (nor the internet actually).

That was very good work. Well Done.
Thanks, I put the link in the main answer just in case
