For a few weeks, cannot access: http://www.opensubtitles.org/ from Firefox.

I can access it from Google Chrome (v48)

Also, just discovered that I cannot access it from Internet Explorer (v8).

I'm running an old Firefox (v28) on XP, but it pretends to be v40 on Win10: "User Agent Switcher" add-on does that.

I created a new Firefox profile with no add-ons, still couldn't connect.

Any thoughts?

And now it's working

I found ads.opensubtitles.org and ads2.opensubtitles.org in my Hosts file, commented them out and rebooted. Made no difference so put them back in.

Cleared my cache and all cookies. Still made no difference.

But, after several hours, I tried again and got there, with an error that was chopped off on the right side of the screen:

Looks like the ads2.opensubtitles.org was causing a problem.

But after trying again, I got there and logged in OK with no errors.

Maybe they are playing around with ads on the web site and don't like it when people block the servers.

No problems here, just using a standard ad-block plugin.

But I never go the site anymore, just use filebot: http://www.filebot.net/

And since filebot handles renaming as well, it's become indispensable.

Yes, I use FileBot most of the time, too. I was explaining how to use FileBot to a friend and wasn't sure if he needed to be logged in to OpenSubtitles.org for FileBot to work, so I was trying to go there and make sure I was logged out to test it.

Today I downloaded two subtitles but don't know if I was still logged in or not. One of those downloads was using a laptop on a coffee shop's WiFi; the other was at home using a desktop PC.

But after I clicked the login button in FileBot running on my desktop PC and logged in to OpenSubtitles.org, a pop-up appeared saying "Your daily download quota is at 2 of 200" - so I think Opensubtitles.org must tell FileBot how many I have downloaded that day, irrespective of my location or device.

Edit:

The Opensubtitles web site says I'm not logged in. So maybe FileBot passes my log in credentials to Opensubtitles to download the files.
