I simply dragged the Firefox “i” icon from the top of this page, into the Chrome window - and this page loaded in Chrome! It worked! Then I tried something just a bit trickier, in the other direction - I first (from a bookmark) loaded into Chrome a page from my local web-development server (i.e. (If you hover over it in Firefox, it says “Show site information” in Chrome, hovering it says “View site information” - that’s the icon I’m talking about.) At the top of both browser windows, at the far-left end of the URL bar, there’s a little icon of the letter “i” in a circle. (I did this on my Mac, but I’m guessing it would work on other platforms too.) I’m reading this article in Firefox, so I opened a new blank window in Chrome. I just tried an interesting little experiment, with a useful result. In the past I’ve just copied and pasted the URL, but (even for just one tab) that is a little tedious.

Since I’ve rarely wanted to transfer more than one tab between browsers, I’m not inclined to install another extension just for that - especially one that (according to your description) closed all my tabs in the process. The organization recommended a privacy extension back then in a blog post on the official Firefox blog that had a "phone-home" feature built-into the extension. The situation resembles another blunder by Mozilla that happened in 2018. The response time was very quick this time. One possible outcome of the "looking into it" could be that Mozilla removes the recommendation. Mozilla employee Gian-Carlo Pascutto responded to the thread stating that the organization is looking into it. It seems like a strange choice considering that the recommended extension appears to use AdGuard code. One of the main objections is that the extension is recommended by Mozilla (AdGuard is not). In the report, he stated that the "extension is essentially a copy of Adguard extension for the core code, and essentially a copy of ABP for the user interface aspect", and that he thought that Firefox users donating to extension developers would surely want to donate to the original developers. Raymond Hill, creator of uBlock Origin and uMatrix, reported the AdBlock Ultimate extension in 2017 but nothing came out of it. The AdBlock Ultimate extension has more users than Adguard currently Adguard has about 322k users, AdBlocker Ultimate 418K.

Rémi found mentions of AdGuard throughout the code of AdBlock Ultimate that suggest that code was copied from AdGuard. The code of the extension is very similar to AdGuard, a very popular content blocking solution. Why is recommending an extension which seems to be a copy-pasting from another extension and potentially in copyright infringement? claims to be open-source and GPLv3 so I installed and checked the sources using the debugger.

published the following message on Twitter today: One of the recommended extensions, AdBlocker Ultimate, appears to be a copycat extension. Other extensions are reviewed after the fact only, if at all. One of the main differences to regular extensions offered on Mozilla AMO is that recommended extensions are reviewed manually each time a new version is uploaded to Mozilla's site (and initially as well). that extensions need to be safe, but some are not.

The new system accepts extensions only if they meet requirements some of these are self-explanatory, e.g. The system used to select these changed recently from featuring extensions on Mozilla AMO to a stricter system.
