  • (2020-06-26) David Post: UI doesn't work at all on latest Chrome, Windows 10, Amazon Prime Video. Clicking on UI elements just pauses and plays the video as if the UI isn't there. Trying to drop a file in just opens the file in Chrome. So, useless.
  • (2020-06-24) António Pedro Sampayo Melo E Castro: works if the subtitle file is on time with the video. However, if it is not, the option to sync the correct seconds does not work properly. If i rewind the video or pause it for a bit the subtitles go out of place
  • (2020-04-15) Aleksandar Galović: Perfect!
  • (2020-04-14) Draguun ReEx: its good

  • (2020-04-13) Gech N: Best subtitle extension ever. I can now watch a ton of foreign language films with ease as the subtitles through the extension sync up perfectly (and they have multiple options to choose from for English if one doesn't work). I'm so happy I found this app

  • (2020-04-07) 7BinksMoctaar: ça marche sur netflix ? SI oui, comment ?
  • (2020-04-07) atman karma: So far so great. Just what I was looking for. I can add subtitles to shows that don't have English. It's simple to use, reasonable quick and it doesn't detract from my viewing pleasure. I've tried a few other which didn't work but this does. cheers I've only been using for a couple of days so I'll update in a month or so.
  • (2020-04-07) Ronn Savage: Amazing wanted to anime with English suns and it worked perfectely on Netflix
  • (2020-04-06) Ana Ćosović: hvala
  • (2020-04-06) Edie Barker Rountree: I don't usually write reviews because I type like I talk, with my hands waving around and very wordy, that being said...I was excited when I found this extension 7 months ago because I don't have tv anymore and need the subtitles to help me hear what words are actually being said when watching/streaming my shows on my laptop now. It worked great for a few months until...it didn't. the past say 3-1/2 months its hit and miss, sometimes it works sometimes it doesn't, when it does half the time the words don't line up with the lip movement, even when I use the lil doodad to fix the speed, and even then there are words in there that aren't even being said on the actual show. The past 2 days (its 4/5/20) it says it "cant connect to the subtitle provider", I've uninstalled then reinstalled multiple times no changes, I'm using an up to date HP Windows 10, Google Chrome browser laptop that everything works fine on, Im connected through wifi but also tried with ethernet just to be sure and nothing makes a difference. I understand this extension is free, and I wouldn't even mind paying a reasonable price monthly for it if it worked 24/7 but it doesn't, because at least twice in a 24 hour period I get an error msg that its under maintenance which is a pain when I'm pulling up my next show to watch. I'm watching normal everyday American tv programs from local networks like Blue Bloods, Chicago P.D. etc no foreign films, so how hard can it be to put the subtitles on them correctly. I wish I knew how because I surely would do it myself for us old folks who need help hearing with our eyes. Sadly there wasn't another subtitle extension out there to choose from, **hint hint someone could probably make a killing from it, just saying. Please fix this thing or give it to someone who can run it properly.

  • (2020-06-25, v:2.1.8) Matt Flor: Does not seem to work on German amazon.de site
    Your extension looks very promising. However, on the German amazon.de site it does not seem to work. After clicking on the extension icon the correct video is found but then clicking on that does nothing.
  • (2020-06-24, v:2.1.8) Lutfar Rahman: Saying try again later

  • (2020-06-24, v:2.1.8) Felis Bieti: Subtitles sometimes don't show up
    Hi! Your plugin is really awesome, a slight problem though: whenever I adjust the sync or just simple pause/resume the video, the subtitles will just disappear. It takes about ~10 seconds for them to pop up again. I'm loading my own srt file, but this also happens with built-in subtitle searching. Please fix? Thanks!
  • (2020-06-22, v:2.1.7) Stephanie Garcia Fields: Videos played in Google Drive

    Hi there, This was working fine for amazon videos and netflix. but suddenly it no longer works on amazon. I click the extension and select the element on screen as always but this time nothing happen - it does find the video element but does not do anything when i click it.. I have reinstalled and it still does the same. IT is working fine on netflix still which is unusual
  • (2020-05-15, v:2.1.4) Ugo B: sous-titres non syncronisés
    J'ai téléchargé les sous-titre du film La cité de la peur en anglais, ceux disponibles sur le site ainsi que ceux disponibles en dehors du site. Les sous-titres sont de bonne qualité, mais ils ne sont pas du tout synchronisés avec le film sur Netflix. Je ne comprends pas. Pourquoi aucun ne sont synchronisés ?
  • (2020-05-01, v:2.1.4) chimemerie uzoma: Prime and Substital
    This has been a great help. It worls on Amazon and countless video websites. However, unlike the description, this does not work on prime video. The extension recognises the video and allows me to select subtitles. However, after I do, nothing happens. No subtitles come up. The video simply continues onwards unsubtitled. I don't know what exactly is the problem but it seems that it is not only me that has this issue as many people cannot use this extension on prime video. Please fix this.

  • (2020-04-27, v:2.1.4) phsyco tater360: doesn't seem to work for icelandic movies or shows
    i was trying to watch a movie titled Goðheimar and I couldn't find subtitles for it, I tried searching and then tried searching in english, I also tried to other shows on the website as well as a movie and none of them had subtitles for english available. I know this isn't a common problem since the language is rare but I'm trying to learn and thought watching shows with subtitles would help, so I thought I would at least let you know the shows I was watching are on the rúv site, which is iceland's local TV station. I tried the movies Metalhead, and World of gods
  • (2020-04-27, v:2.1.4) William E. Smith, Jr.: Not working on amazon prime
    using the latest Chrome on both a windows 10 and imac running Sierra, the extension shows a subtitle available but when click on the subtitle, the video just pauses and no blue icon appears to control subtitles. Also manually downloading a .srt file from opensubtitles.org and loading it does now work either. Am i doing something wrong?

    Hello, this extension was working fine for a while, but now once I add the subs, whatever I'm watching won't play. It adds the blue Substital play button over the original one and it just won't start the video at all.
  • (2020-04-07, v:2.1.4) Dwinanri Egyna: Prime video - JAPAN
    I was so excited for the extention because I've been meaning to watch things on Prime Video. However, the amazon.jp only have japanese subtitle and that means I can't understand anything unless it's in English. Sometimes even English would drive me crazy because, huh, accents. But for some reason, it hasn't been working properly. Some that works would be extremely delayed or too fast and I can't seem to adjust the timing properly, even after checking the srt file from the source and calculating the difference. On some videos, it doesn't show up at all. Could you let me know what I can do or might have done wrong? Thanks!
  • (2020-04-07, v:2.1.4) Akhil Deshpande: Doesnt work on prime
