I'm on an Imac 10.7.5, using FireFox 24. Suddenly, all the files I download through FF could not be accessed from anywhere else in the network except my Imac. I finally checked the downloaded files permissions to find that FF started to restrict group access (anyone = No access). Never had this problem before. Somehow FF started not obeying the permissions settings of the target folder. I tried lots of fixes, I even deleted FF with all its relevant files..made a clean install but the problem won't go away. Important to note that Safari and chrome are still downloading all files with correct group permissions.
Solved! Go to Solution.
could you tie the change to the last firefox update?
maybe it's a bit far fetched, but you could try to enter about:config into the firefox address bar (confirm the info message in case it shows up) & search for the preference named browser.download.manager.scanWhenDone. double-click it and change its value to false.
Thanks a lot philipp, I just tried it but still no joy. I am certain this did not start with the latest update. FF 24 was respecting group permissions up untill 2 days ago!
can you try to replicate this behaviour when you launch firefox in safe mode once and download a file?
here's another question from yesterday which connects that behaviour to the update from 23 to 24: https://support.mozilla.org/en-US/questions/975473
Trying the safe mode was one of my very first attempts, I assumed it could be an extension or a plug-in causing this but no use. Now I have to manually change every file's permissions after downloading it or open Safari each time I download anything. Still pretty sure FF 24 worked fine before, but I could be wrong. Maybe I should try a downgrade?
though downgrading is normally not recommended, you could just use it to test if it has really been caused during the update from 23 to 24: Install an older version of Firefox
i'm still trying to find out if this has been a deliberate change (maybe to address some security concerns) - otherwise it's probably best to file a bug for that issue...
I'll certainly try the downgrade this problem is a real nuisance. I can understand it might be for security, but when downloading a file into a shared folder it means you intend to access it all over the network.
Thanks a lot for your help philipp
