I can use firefox just fine (win10 home, v2004, os build 19041.1415)- I only get the XPCOM error when trying to open the Eset protected browsing window (for banking and protection). This has not happened before when using/updating Firefox and only just happened when I updated Firefox today to 96.0.2.
I've been browsing the XPCOM queries and have tried the basic reinstall (deleting program folders prior to installing) with no luck, but so far but wanted some clarity prior to trying other things-
Some of the answers here point out that security software can block the folder access when Firefox attempts updates/installs. I attempted an install with Eset paused, but no change. On another computer, a similar problem - a firefox error message occurs when trying to run the Eset protected browsing window, so attempted the same "program folder delete>reinstall" method, only now when clicking the Eset window, it just gives the loading symbol then nothing happens. Again- Firefox also works fine on that computer as well save for the same protected window usage. Not the same error, but still similar enough to think it's related.
Is a safe mode firefox install the next step forward? Should firefox be uninstalled prior to doing so? (Not just deleting the program folders via file explorer, but an actual uninstall process). Or is this something that should be breached with Eset tech support (beyond just pausing the internet protection and functionality, should it be uninstalled prior to firefox reinstall and than installed again afterwards)?
Please advise and thank you in advance!
