Waterfox: Stylo – layout.css.servo.enabled – in Waterfox

Created on 25 Dec 2017 · 12Comments · Source: MrAlex94/Waterfox

From https://www.reddit.com/r/waterfox/comments/7jndj6/waterfox_5601_is_now_available_for_download_with/dr8fppp/:

… no Stylo? …

about:config

layout.css.servo.enabled
true

Result:

Stylo true (enabled by user)

… about:support says "false (disabled by build)". …

… I guess that it's not disabled, in that way, with the (experimental) port to FreeBSD, …

tl;dr

It seems that for (at least) Windows, Stylo is disabled at build time for Waterfox 56.0.1.

https://github.com/MrAlex94/Waterfox/issues/298#issuecomment-349742544 draws attention to Mozilla bug 1341234 - bindgen doesn't pass CFLAGS for optional system dependencies

For what it's worth: with Stylo enabled in 56.0.1 on FreeBSD-CURRENT, I have not encountered any problem that I might attribute to the feature.

I can't find layout.css.servo.enabled on Waterfox 56.0.1 Debian 9 at all

You can add it, as a boolean.

For reference only, some things that I bookmarked a few weeks ago. Not intended to be comprehensive:

Cross reference: Why is stylo disabled ? : waterfox

grahamperrin on 26 Dec 2017

I've added it as boolean and it's still disabled (due to build)

OK, I guess that Mozilla bug 1341234 makes it difficult to build Waterfox with Stylo on Linux.

Stylo from FF56 has many security issues fixed in FF57 (via fuzzing). MFSA 2017-24 only documented those that also affect non-Stylo code. During FF58-FF60 both non-Stylo (Android, ESR52 for critical) and Stylo would receive attention but after FF60 only Stylo.

With Waterfox 56.1.0, Stylo is enabled and built on all desktop platforms.

Two points:

extension incompatibilities, such as the one at https://github.com/MrAlex94/Waterfox/issues/332#ref-issue-284962197 above, should be rare
#498 (Waterfox, or a tab, crashing at https://bintray.com/) is probably an edge case.

I reckon that we can close this issue 332.

Looking ahead, beyond desktop platforms

Mozilla bug 1366049 - (stylo-android) enable Stylo for Android was

RESOLVED FIXED in Firefox 59

– and from Quantum-related https://github.com/MrAlex94/Waterfox/issues/267#issuecomment-376351366:

… While still under research, I plan to plant base in 60 ESR for a "future" variant of the browser. …

Without reopening this issue (unless you'd like to, @MrAlex94):

… extension incompatibilities… should be rare

Re: #512 (fixed in the port to FreeBSD) _Speed Start_ might be added to the shortlist.

… Waterfox, or a tab, crashing at … is probably an edge case.

516 is another case.

From pull request https://github.com/MrAlex94/Waterfox/pull/511, merged a few minutes ago:

Stylo from Firefox 56 is affected by many Web compatibility and security issues. It also crashes and degrades performance in some situations.

At https://www.reddit.com/r/waterfox/comments/7bj77g/-/dx12nol/ I have a shortlist of known cases/situations where users of Waterfox 56.1.0 have been affected. Just a shortlist; not intended to be comprehensive. Plus https://disqus.com/home/discussion/waterfox/the_waterfox_blog_waterfox_5610_release/#comment-3846181598 the question about why the feature was added/enabled; and so on.

Sorry for not testing more thoroughly!
