User Reviews

It works fine, but is limited to +/- 5 seconds, you can't move subtitles more than that, so that's an issue when the actual delay is >5s. Also, you can use mouse only and you need to click each time to move the time by 0.05s, and each time pauses / starts the video. My tips if you'd like to work on this - otherwise very useful - addon: 1. Expand the limit to more than 5s, od disable it entirely 2. Enable the field to enter the time value manually 3. Enable the slider or remove it entirely, it's impossible to adjust it for all needs. Thanks for this, very handy tool :)

Is SubSync Lite Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

SubSync Lite requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

SubSync Lite is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
