Hello, dear friends. Browser updated itself to version 49.0. However, Firefox restarts and nothing happens. There is a Firefox.exe running in system processes. But there are no any error messages nor a Firefox's window. I've checked Crash reports folder. But there are no new files dated this month. I've launched Firefox in safe mode via Windows key + R -> firefox -safe-mode - still the same issue. Turned off my AV and any other soft, restarted PC many times and so on. Moreover, I've tried to install new Firefox in Sandboxie (sandbox utility) - also nothing happens. Firefox launched as a process and that's all. 10 mins, 30 mins - nothing. Could you be so kind and let me know if it's possible to fix this issue somehow, please? I've downgraded my FF to 48.0.2 and it works fine, but you know - it'd be nice to have an upgraded one. Thank you in advance.

You may have corrupt xulstore.json or Localstore.rdf file.

Close Firefox. Open your file browser to this hidden location:

  • Mac: *~/Library/Application Support/Firefox/
  • Linux: *~/.mozilla/firefox/
  • Windows: %AppData%\Mozilla\Firefox\
  • *C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\

Locate the above files. Then rename or delete them. Restart Firefox.

hi, mozilla just released an update to firefox 49.0.2 that should fix a problem that sound pretty similar to what you've described. you can download this new version from https://www.mozilla.org/en-US/firefox/all/ to see if it works for you too.

Hello, philipp. Thank you for reply. I've been checking the topic made by assistance-multi regulary. And it's a pleasure to see that problem been solved. Yes, I've just installed the update 49.0.2 - all works perfectly fine. I really appreciate Mozilla's community. Thank you, mates!
