Dev tools / Inspect element window doesn't open on latest brave releases (VERY slow to open) #14721

shanytc · 2021-03-15T08:19:28Z

Description

On my MacBook Pro (13-inch, 2020),
The latest brave browser releases completely broke the inspect element window. It will no longer open immediately, and if it does, it's after 30 seconds or 1 minute sometimes not at all. When it does open it's unresponsive.

Steps to Reproduce

Install Latest brave releases for OSX
Open any page
right click -> inspect element -> it's not showing / takes around 30secs to 1 minute to open

Actual result:

Opens after 30secs or 1 minute like this: https://ibb.co/HtMLgGg

Good to know! Seems this is a wide issue.

…1.22.x" Fixes brave/brave-browser#14721 for 1.22.x Problem still in `1.23.x` and `master` branches Auditor: @darkdh This reverts commit 27cf5ef, reversing changes made to e104d7c.

bsclifton · 2021-03-23T18:29:18Z

Fixed in 1.22.x with brave/brave-core@f20e8ba

This is still a problem in other channels though ☹️ We can probably keep this issue open as a blocker for 1.23

kjozwiak · 2021-03-23T20:08:02Z

As per the above, we reverted the change that caused the issue in 1.22.66. The fix that will address the underlying problem will be done via #14880.

kjozwiak · 2021-03-23T20:18:39Z

@brave/legacy_qa we'll basically need to make sure that the DevTools is working as expected on a default install. The fix that will address the underlying problem will be done via #14880.

As per @darkdh, this was due to the following:

It is because adblock intercepted requests from devtools, and because we have cname adblocking, so we would look up the cname of devtool
When DoH is on, it usually has no problem but when the setting is automatic(default) or off, system resolver will not able to resolve the cname and hang there until timeout

Looks good on macOS 11.2.2 using the following build:

Brave	1.22.67 Chromium: 89.0.4389.90 (Official Build) (arm64)
Revision	62eb262cdaae9ef819aadd778193781455ec7a49-refs/branch-heads/4389@{#1534}
OS	macOS Version 11.2.2 (Build 20D80)

Ensured right click Inspect on web page opens up dev tools
From hamburger menu -> Developer Tools opens and closes with no issue

Wasn't able to reproduce this issue on macOS 1.22.66 arm64 builds.

shanytc · 2021-03-23T22:39:00Z

1.22.67

Issue still persists in this build.
Developer tools will not open on a fresh new install.

kjozwiak · 2021-03-23T22:44:00Z

1.22.67

Issue still persists in this build.
Developer tools will not open on a fresh new install.

@shanytc have you edited the DoH settings under brave://settings/security by any chance? Example:

We've checked every platform using 1.22.67 and it seems to be working. When you go into brave://version, are you seeing 1.22.67 or 1.22.66, Also, which platform are you using? Sounds like OSX? Can you let us know the exact version you're on?

Here is the version information I'm running:

Brave	1.22.67 Chromium: 89.0.4389.90 (Official Build) (x86_64)

OS	macOS Version 10.15.7 (Build 19H524)
JavaScript	V8 8.9.255.20

I have the same DoH settings under brave://settings/security as you posted in the image.

I tested with:

Secure DNS off -> Doesn't open
current service provider -> 1min-2min to open, , very slow and unusable.
custom dns: Google, Cloudflare..etc -> will take 10-20secs to open, very slow and unusable.

Hello,
I updated Brave to the latest version but the developer tools are still loading very slowly.
Having this issue for a while now.

macOS Catalina 10.15.7 (19H524)
Brave Version 1.22.67 Chromium: 89.0.4389.90 (Official build) (x86_64)

shanytc · 2021-03-24T10:00:51Z

I have no idea who tested the fix, but clearly it hasn't been fixed.
Also, why would you want to do DNS check for opening a developer tools...?

riequilibrium · 2021-03-24T10:16:34Z

It seems that the built-in adblocker is intercepting the devtool call, disabling the Secure DNS or using another DNS like Cloudflare actually fixed the slowdown, but it is clearly a temporary workaround.

You can try it, go to Settings->Security, under Advanced you'll find the option for Secure DNS, select Cloudflare and now the devtools should open instantly!

Hopes this helps you!

M-BenAli · 2021-03-24T11:29:54Z

Relaunching brave fixed the slow developer tools startup for me, this option is ONLY be available if the update hasn't fully been completed yet. Go to: Settings -> About brave ->Relaunch brave option.

Can confirm this works as a fix for now, using Cloudflare DNS

It still takes around 10+ seconds for the developer tools to show up with CloudFlare DNS... this is a hack and not a solution.
Developer tools should not even use any dns remote check.

dougfarnes · 2021-03-24T16:12:57Z

This is not completely fixed for my install either.

@kjozwiak, my settings are as shown in your screenshot and dev tools take forever to open right now. However, if I apply the workaround by @riequilibrium (forcing Cloudflare DNS), dev tools open instantly. Also, if I connect to a self-hosted Wireguard VPN, dev tools load without delay.

Not sure what this means, if my local DNS setup is conflicting with what Brave is trying to do vis-a-vis CNAME adblocking, or how that relates to dev tools, but wanted to add another data point.

Thanks a lot!

This has been driving me bonkers! But at least this issue has lead me to discover raindrop.io while I run Firefox :)

Can confirm that the Nightly version appears to also work for me running macOS Version 11.2.3 (Build 20D91)

@garyburgmann if you update the Release channel version, it should now be fixed too 😄
