Why you SHOULD be using Firefox

Firefox Has Quietly Integrated Brave's Adblock Engine

Mozilla shipped it in Firefox 149 without a mention in the release notes.

Still a work in progress but seeing it accepts uBo syntax rules is already a good positive. If they allow custom rules/filters in future and add in the element picker from uBo then I'll be willing to try it.

Gave it a quick go knowing its a hidden feature so early days yet and found it broke the captcha screen I get when using the VPN to sign in to Facebook so I undid the changes for now and will wait to see how it matures.

Tonight I have found two more things that don't work in Firefox but are fine in Edge.

I was looking at a Reddit thread and noticed some of the text was overlapping.

Displayed correctly in edge.

I just tried uploading some images to copilot for it to summarise for me and it failed to upload in FF.

Works fine in Edge.

Try uploading images to copilot and see if it works...

I was able to upload an image to Copilot. Perhaps something like uBlock Origin is blocking it, or one of uBo's rules, although I was able to upload the image with that enabled, as well as Firefox's Enhanced Tracking Protection being left on.

Ok well that's strange. I don't run any add-ons so mine is basically vanilla FF.

I don't see any overlapping text on Reddit either. Not using any Reddit related extensions so it's also the vanilla experience, apart from uBo removing ads.

Not noticed any overlapping text on Reddit though I don't use it extensively just dip in certain sections semi-regularly.

This is the page I was looking at with the issue.

Ok so on a refresh of the page it is actually rendering OK now.

Yea I've seen FF do that a couple of times, it's rare though. And in my case I have ublock and block a load of stuff on reddit
