2006822 - [Regression] Since version 135.0 DevTools Network tab doesn't log requests if URL prefixed with view-source:

Status: RESOLVED FIXED

(DevTools :: Netmonitor, defect, P2)

Description

[a.broughton.en]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:146.0) Gecko/20100101 Firefox/146.0

Steps to reproduce:

1. Open firefox to new tab
2. Open DevTools (F12 or Right-Click Inspect in page or CTRL+SHIFT+I)
3. Select Network tab
4. Select Settings cog on right side and ensure Persist Logs is selected
5. Visit URL: view-source:https://bugzilla.mozilla.org

Regression in version 135.0, version 134.0.2 and before correctly log the requests in the network tab

Version	Status
134.0.2 (64-bit)	Shows network request - OK
135.0 (64-bit)	Network request now shown - !OK

Nightly 148.0a1 (20251217214341) tested, also faces regression.

This was discovered while tracking redirects from a malicious link, it redirected through three different domains and not a single requests was logged if the URL was prefixed with view-source:. Versions prior to 135.0 worked as intended / expected.

Actual results:

No requests listed in Network tab

Expected results:

Request should have been logged

Type in table: 135.0 Status should show not shown, instead of now shown.

Version	Status
134.0.2 (64-bit)	Shows network request - OK

Thanks for filing. Interesting. I wonder if this was affected by Bug 1932818

Is the needinfo and regressionwindow-wanted requesting information from me? Regression is since version 135.0. What other info is required?

the needinfo is for bomsy to look at, and the other flag was to run mozregression (https://mozilla.github.io/mozregression/) to get a shorter regression window, but that wasn't for you to do, you're all good :)

I was only able to get this pushlog https://hg-edge.mozilla.org/mozilla-central/pushloghtml?fromchange=b6fe6098a8bbf74edca23103c6756be13d238378&tochange=c9170b504cdce7fd51d1934bad32709bea49b112 , which is a bit large, but does include Bug 972821 and Bug 1932818 , which could impact this

Hi a.broughton.en,
Just got back from holiday, yes it was as Nicholas said, the need-info was for me.

Thanks Nicholas for the regression window to confirm, i'll take a look to fix

P2 since it's a regression and bomsy already started investigating the issue.
