README: Targets (supported browsers) unclear

[Chealer]

The README file describes this extension as follows:

Auto Tab Discard

A browser extension which uses the native tab discarding method (chrome.tabs.discard) to automatically reduce memory usage of inactive tabs. This extension is more efficient and should be less buggy compared to the alternatives extensions that use DOM replacement method.

There is no explicit indication of which browsers are supported. The paragraph's mention of chrome.tabs.discard suggests only Google Chrome―or browsers using its engine―are, but the Links section suggests otherwise, since it mentions Firefox (which is based on Gecko).
