I also disabled the screenshot tool because why does the browser need a screenshot tool? You can just screenshot the browser with an external program or the classic print screen key.
The print screen key only captures the visible part, not the entire page.
The built-in tool allows to capture the whole page and also to easily define the part of the page to be saved with some kind of automated selection. It's easy to use and a really handful tool.
Why should I have to use an external tool while the built-in one has everything we need ?
Not to mention all of the tools I've tried have problems to capture the entire page on some sites.
Please restore back this useful feature.
EDIT: I've found a workaround.
First copy the
screenshots@mozilla.org.xpi extension from an older version of R3dfox (last one to have it is v137.0.2) or from Firefox to the \r3dfox\core\browser\features folder. Create this destination folder if it doesn't exist yet.
Then in about:config set screenshots.browser.component.enabled to true.
You may need to restart R3dfox.
