broken - after clicking the film title after searching, the extension will load endlessly.

I only downloaded this because the site says "extension users get instant downloads". Apparently that's no longer true...

Open subtitles no longer 'open' but pay to play -- avoid.

Please add the ability to download subtitles, the sites that have subtitles can download the subtitles

It got the job done, but I hadn't been able to load a subtitle onto videos (html5) the last few times I tried to use it. The subtitle statistic said it had 0 lines and the duration was 00:00:-01. There was also no preview of the next three lines. It wasn't like this when I first installed it and started using it. I did a test and tried several different subtitles on other websites, even YouTube, from movies I wasn't watching and the statistics would read the same, every single time. No subtitles would appear. I even uninstalled and reinstalled. Please fix. UPDATE: I noticed this only happens when I watch more than two videos back to back, like if I'm binge watching a tv show. It worked again when I tried again the next day, but that sucks. Reply to developer: I am using the subtitle search, binge watching The Lincoln Lawyer, using the show's title as the search query. I also used the same search query for YouTube to test if the subtitles would appear despite the difference in content.
