Error message: "couldnt find entry point moz_create_arena in mozglue.dll"
After installing Firefox 59 this error message pops up (in German so the error message in the title is translated by me) for one of my apps. Quickly followed by a second error message "Couldnt load XPCOM".
The operating system is Windows 7 64 bit and the browser is Firefox 59 as per update this morning. Normal webbrowsing works fine as far as i can tell.
Chosen solution
I went through the whole process but the error persisted.
What I still have to tell you is that the problematic browser is supposed to run in a sandbox. (the new FF in other sandbox instances is running fine from the get-go btw) So I now realised that the sandbox in question had its own "program files/mozilla firefox" folder with a couple of (old?) files in it. I deleted them and now it works.
Case closed. Thank you for your help. At least I got to run the Windows Disk Cleanup, hehe. Do I have to mark this thread as "answered" or anything?

Hi, Nothing on that one last person back in November reinstalled Firefox for the issue so please : uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files , C:\Program Files(x86) & C:\ProgramData Then restart system. Then run Windows Disk Cleanup. (Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do :

Reinstall with Current Release Firefox 59.0 with a Full Version Installer
Please let us know if this solved your issue or if need further assistance.

fyi: Firefox has it's own sandbox running for important files. https://wiki.mozilla.org/Security/Sandbox
