For developers

Source code can be found here The files in ./src/bundle/*.js were generated with npx rollup --config --bundleConfigAsCjs rollup.config.js due module usage.

Nice amazing and helpful little addon! One suggestion, make use of the firefox's "plugin shortcuts" and let us trigger how2say by customized shortcut, then it would be perfect :). Thanks for this addon!

Is How2Say 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.

How2Say requires a lot of sensitive permissions. Exercise caution before installing.

Risk impact analysis details
  • Critical Grants access to browser tabs, which can be used to track user browsing habits and history, presenting a privacy concern.
  • Critical ****** ****** ** *** ********* ****** * *********** ******** **** ** ** *** ******* *** ****** **** **** *** ******* *****

  • Medium ****** ********** ** ******** ********** *** ********* ******* ******** ****** ******** ****** ********
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.

How2Say is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
