If you’re having some problem browsing multiple websites on the Firefox browser on your Windows 10 computer, then this post might be of help. One of the most common problems you could encounter in Firefox is mostly related to HTTPS and one of them is the MOZILLA PKIX ERROR MITM DETECTED or ERROR SELF SIGNED CERT or SEC ERROR UNKNOWN ISSUER error which means that Firefox was unable to trust certificates issued on secured websites.
If you encounter the MOZILLA_PKIX_ERROR_MITM_DETECTED error in Firefox, this indicates that something in your network or system is interrupting your connection and injecting certificates and when that happens, Firefox won’t trust it. In such cases, one of the culprits is malware. Malware will try to replace a legitimate certificate with its certificate. Another cause is security software where it keeps a tab on a secure connection and creates a false positive, for instance:
“In Microsoft Windows accounts protected by Family Safety settings, secure connections on popular websites like Google, Facebook and YouTube might be intercepted and their certificates replaced by a certificate issued by Microsoft in order to filter and record search activity.”
And if you are connected to a corporate network, there might be a monitoring/filtering product that could be replacing certificates. Moreover, there are also users who reported getting this issue when they use the Nightly version of Firefox. And if that’s the case, you have to try accessing secure websites using only the stable build especially when it comes to payments. However, if you are not doing that, then here are some options you need to check out.
Each security-based software has a security option that allows you to turn off the HTTPS scanning functionality. They may be available under different names such as HTTPS Scanning, Scan SSL, Show safe result, Do not scan encrypted connections, etc. Find what is applicable for your security or antivirus software and then try turning it off temporarily and see if it helps in fixing the MOZILLA_PKIX_ERROR_MITM_DETECTED error in Firefox.
The next thing you can do if the first option didn’t work is to disable security.enterprise_roots.enabled which is an HTTPS certificate check on Firefox. Note that this is not recommended but you have to at least try in order to fix the error.

This is a common Device Manager Error Code that users encounter. It is commonly found on all Windows 2000 and later versions of Windows operating systems. Error Code 36 is usually prompted by the following message:
"This device is requesting a PCI interrupt but is configured for an ISA interrupt (or vice versa). Please use the computer's system setup program to reconfigure the interrupt for this device. (Code 36)"
Error Code 36 occurs when there is a failure in IRQ translation due to your Windows operating system getting corrupted. This is caused due to a number of triggers, such as:
When programs are removed excessively, some programs are not removed completely and create problems in your computer’s registry.
Also, due to the presence of malware and spyware and other causes mentioned above, your computer registry builds up errors with the time that leads to slowing your PC, time lags, and even result in crashes and freezes.
Error Code 36 can cause internal and external components to malfunction or experience time lags such as DVD drive or printer and hence can severely affect your entire PC.
Error Code 36 is a severe PC error and any attempt at fixing the error must be approached with extreme caution for your PC to start functioning properly again. Here are two methods to fixing your PC.
Changing the IRQ reservation settings is the best way you can rely on to fix the error code. You can do this by changing the BIOS settings of your PC.
The BIOS stands for ‘Basic Input/Output System’ and is the program of your PC’s microprocessor that allows your PC to boot after you switch it on.
Caution needs to be exercised before changing the BIOS settings of your PC. This is because every PC’s BIOS version differs from another and any wrong attempt to change the settings may make matters worse.
It is therefore recommended to refer to hardware documentation that you received with your PC or motherboard and check for the model number and details of your PC’s motherboard.
Only after you have checked and confirmed all the details, should you use the specific BIOS settings required to configure your IRQ reservations?
Error Code 36 isn’t an easy error to remove.
While changing the BIOS settings can work to restore your PC, it may create a whole lot of inconvenience for finding the time and effort to check the hardware documentation details and attempting to change the specific settings and especially, if your PC does not support the options to change IRQ reservations.
Given the high risks of fixing such an error, you can also install software that enables you to fix your slow PC at the click of a few buttons.
Programs such as DriverFIX can enable you to download and replace your outdated drivers with new updated ones without you having to look for them. It will detect which drivers to download based on your PC’s motherboard version from the program’s database and can get rid of error code 36.
