You don’t have to open the main
@FirefoxDevTools pane to use the Eyedropper. If you put the "Developer" button in your toolbar, it‘s two clicks away.pic.twitter.com/OfKvuZf0g7

I was working on some `:visited` styles, and couldn’t figure out why the alpha of my `hsla()` was being ignored. I moved it to `opacity` and it still was ignored… but Firefox reminded me WHY it was being ignored. Thank you, Firefox! I had somehow forgotten about those limits.pic.twitter.com/hcIlVswQ8y

Exclusion filtering in Console was brought up by
@wesbos in https://twitter.com/wesbos/status/1216785228255170560 ….

In case you missed
@syntaxfm's "A Month on Firefox" (aka "DevTools are really good"): https://syntax.fm/show/213/hasty-treat-a-month-on-firefox … One of the bugs mentioned by@wesbos was CORS errors. CORS can be a headache, so in DevEdition 73 those work as expected –

So I ventured into contributing to
@FirefoxDevTools. I want to add a "Store as global variable" in the breakpoint panel. The dev tool is a giant React/Redux app. I've got a first working POC against any hope

@syntaxfm the changes tab in@FirefoxDevTools has been CRITICAL to helping my web design students design in the browser. And, being able to see the events assigned to DOM elements in the inspector has helped immensely when navigating a project with hundreds of JS files.

The console autocomplete popup now displays variables, functions and classes declared in the input (even if the expression wasn't evaluated yet). This should help when writing longer snippets

#DevToolsAdvent Did you know you can Save & Import performance recordings in the@FirefoxDevTools Performance Profiler?
After you record a performance snapshot, you can save it as a JSON. You can import it back. That means you & your team can all work on the same baseline.pic.twitter.com/tXfTEbAdvsThanks. Twitter will use this to make your timeline better. UndoUndo
