Like others have said, uBlock Origin ( or solid alternative; uMatrix, etc ) at this point is a prerequisite for any browser.

I am not testing something that puts me in danger and throws me into the festering garbage dumpster that internet is these days without it. It's like testing a car that doesn't have brakes yet.

Protection in layers.

Pi-hole at the DNS level, ublock origin and fingerprint protection at the browser level.

If the latter two are missing because I'm testing a beta browser which is very likely to a) deliver them and b) help defend against a chrome monoculture, I feel alright about sshing into a VPS to update pi-hole and then taking it for a spin.

So don't test, it's not mandatory...

I am a developer and spend half my work time in Firefox Nightly. This is not usable for me despite being exactly the target for this preview.

[Touche]

The target of a preview is not people expecting it to be feature complete, so no, you're not the target.

[Ultramanoid]

Tell me how am I supposed to test add-ons on this Firefox as a developer before the release then.

Edit : And again, most of my work if not all related to Firefox, I do on the Nightly build. I expect things to break, but this preview ( of which there have been builds for a while already ) is a non-starter.

Why are you assuming that addons will be added in the GA release, and not some version prior to the GA release?

[Ultramanoid]

These builds have been available and in development for months now. They are announced at this time for 'early adopters and developers' ( EXACTLY us ) and still not even a hint of add-ons, or any obvious / apparent interest in them from Mozilla.

The only way to use uBlock Origin and / or uMatrix ( which again, many of us argue are essential, on top of add-on development itself ) on Android today is Firefox. Yet there have been nothing but vague replies these past months about when development from Mozilla will pay any attention to this, arguably its biggest differentiator and advantage compared to the spyware army of Chromium / Chrome clones on the biggest platform accessing the internet today.

[damnyou]

Simple, wait until addons are supported.

[Ultramanoid]

Wait until about:config is supported too ?

These preview builds have been available for months, not just a couple of days.

Nothing I or my co-workers can actually test yet in them.

No official statement about add-on support which should be at the forefront of development in any Firefox version, the best we get is vague replies about it coming later.

[m-p-3]

It's not like other previewers can run add-ons anyway, it will come in time.
