[Fixed in v80] Google Chrome 79 breaks hovering over variables in Chrome DevTools to show value

New updates are being added at the bottom of this story…….

Original story (published on December 19, 2019) follows:

Google Chrome is more than a typical web browser. The app has hundreds of millions of users across the globe, making it central to any Web developer’s considerations.

Google regularly adds new stuff and makes changes here and there through software updates. Obviously, developers will want to keep up with the pace by taking advantage of everything Chrome throws at them.

The latest Google Chrome update arrived last week as version 79. Sure, you can expect several bug fixes and performance optimizations from this update, but things haven’t been great for everyone.


Perhaps the biggest issue of Chrome 79 was tied to the data bug. Apparently, the update came with a serious bug that hid user data from apps that rely on the WebView framework.

Google has since addressed this issue and resumed rolling out the Chrome 79 update to more users across the globe. However, it is also emerging that the same Chrome 79 update has a disturbing issue in DevTools.

The screenshot above was taken from Google support forums. Below the original post, tens of affected developers have also confirmed that indeed this is an issue affecting the latest Chrome 79 DevTools.

Same problem here. Also “Display variable values inline while debugging” is no longer working. Combined these two issues seriously impact on the usability of the debugger. Using Windows 10.

When debugging in Chrome DevTools, hovering over variables should show the associated value, instead, Chrome 79 DevTools show nothing on hovering over variables. Given that Chrome 79 has only arrived, we wait to see when Google will address the issue.

Update (December 27, 2019)

Apparently, the current Chrome 80, which hasn’t hit the stable channel yet, has addressed this issue. For now, we don’t know when the stable update will be released, but it’s great to see devs working swiftly to resolve the issue.
