Firefox couldn’t open and the accompanying mistake is shown on screen: “Couldn’t load XPCOM”. The XPCOM blunder may cause on a Windows-based computer at whatever point a client tries to open Mozilla Firefox after a Windows Update or if the Firefox’s profile envelope is corrupted. Firefox’s profile organizer corruption may occur after an infection attack or after installing a third party extension on your Firefox program.
When I tried to start the Firefox internet browser today I got two mistake messages instead of the internet browser. It would not start along these lines, which left me confused for quite a while.
The first mistake read “The program can’t start on the grounds that pgort100.DLL is absent from your computer. How can I fix: Couldn’t Load XPCOM Error?“. The main option was to hit on alright, which caused the second mistake prompt to show up on the screen.
This time it read “Couldn’t load XPCOM”.
I’m running Firefox Nightly, the cutting edge rendition of Firefox which sometimes has issues. It happens infrequently, and I never kept running into startup issues when utilizing the program.
It was in all respects likely that the last update of the program some way or another caused the issue. Either in light of the fact that it was not connected correctly or in light of the fact that something had not been updated legitimately.
At whatever point I encounter blunders encompassing DLL or other loading mistakes, I restart the PC to check whether they leave afterward. This time though, a restart did not resolve the issue. The couldn’t load issue was still being shown on the screen.
I then tried to discover increasingly about all that was missing: PGORT100.dll. A snappy web seeks uncovered that it was part of Microsoft’s Visual Studio, the Microsoft Profile Guided Optimization Instrumentation Runtime.
I was not ready to locate it on the system. Instead of looking for that document now on the Internet, I settled on the choice to just install Firefox once more.
Another installation should add the missing record back to the system, and since it doesn’t touch the profile directory by any means – which contains all the custom data of Firefox like bookmarks, program extensions or themes – it ought not to bring about any further issues.
I realized that the issue would not be settled on the off chance that it was an issue of the latest Nightly form, and not a neighborhood issue that just I was encountering.
Still, it was my best shot. I downloaded the latest Firefox Nightly form and installed it to a similar directory that the past installation was installed in.
I then propelled Firefox and lo and see, the XPCOM blunder was gone and the program started up like regular.
In short, here is what you might want to do:
Restart the PC and try to load Firefox once more. In the event that the blunder persists, go to 2.
Download the latest Firefox installation document from Mozilla and install the internet browser over the existing installation to fix the XPCOM blunder.
In the event that you are encountering pgort100.dll or XPCOM related mistake messages in Firefox amid start, try installing the program over again.
I still don’t have a clue what caused the issue in the first spot. For my situation, the most likely explanation is that the most recent Nightly update somewhat got things failed so a few documents were not updated correctly.
