Second time after updating all portableapps , firefox did not start , giving just an error message:
Couldn’t load XPCOM
It happened first time with 101.0 and today with 101.0.1
What I found out to make it running again:
downloaded FirefoxPortable_101.0.1_English.paf.exe from https://portableapps.com/apps/internet/firefox_portable
extracted with 7-zip
copied all the folder and overwritten the original in portableapps folder
Firefox started again and all my bookmarks and plugins are still with me
Question: what to do now , so I will not have to repeat this operation for the third time after next update?
