IceCat hangs when entering web pages such as instructables.com. I
supposed it was because it has a lot of Javascript. Nevertheless, the
problem occurs even when these plugins are activated:
Disconnect
GNU LibreJS
SpyBlock
uBlock Origin

Isn't SpyBlock an addon which does what uBlock Origin does?
It's a bit difficult to help with "it hangs" issue descriptions,
can you be more specific?
it could even be an upstream issue.

For now we should wait until the new version is available on
Guix and then you could try and see if your issue has been
fixed?

There's a workaround for Icecat hangs. You have to set the skia rendering

Something like

gfx.canvas.azure.backends = skia
gfx.content.azure.backends = skia


This has been discussed in the past, see here
https://lists.nongnu.org/archive/html/guix-devel/2017-02/msg00972.html

There are more mentions of skia, just search the mailing list archive

Thank you very much. Those are the exact symptoms.

I see now where to correct it. It is specified in:
https://lists.nongnu.org/archive/html/guix-devel/2017-03/msg00177.html
I will report my results.

I cannot reproduce the hang (perhaps you meant crash?). I'm using the
skia backend as others have explained. It stopped the frequent and
random IceCat crashes at the cost of crude text rendering.

I hope we can solve the problem with the cairo backend at some point!

Thank you very very much all of you for your help.

I meant crash. I think the problem is solved. I am not sure. The
problem was not always. I will report.

I wonder why those parameters are not set by default to skia while the
problem with cairo is fixed.

Actually, such a change was committed 3 weeks ago by Mark H Weaver.

2abf6371cc gnu: icecat: Add fixes from mozilla-esr45; use skia by
default.

But it might be that it will only take effect in new IceCat profiles
(i.e. if you have used IceCat before the fix, the cairo values might be
cached somewhere?).

Anyway, I'm glad you got it working better!
