How do you secure against the system vendor (in this case the browser) limiting what the consumer/user can or can't do (alone or with the help of third parties) with the product after acquiring it though? After all security for individuals against commercial and otherwise organized interests is one of the, if not the most important security after life and health. Even if one values the market overall for financial reasons, there is a solid argument that preventing modifications (and thus also repairs) is anti-competitive. It would be damaging to society if manifestV4 is realized restricting what can run further, much like printers and operating systems where the users ability to run software they bring themselves is limited has been. Just as no one should have to go to a mechanic with a special deal with the manufacturer to get their car or tractor to work as desired, neither should users of software.

If you don't like what a browser is doing, then move to another one? You're acting like you have spent a tonne of money on buying Chrome. Even if that was the case, it's not a clear case of an anti-user behaviour. There is a good reason to deprecate the webRequest API, and we'll see more browsers move towards that in the future (Safari has had declarative blocking for many years now, I believe).
>preventing modifications (and thus also repairs) is anti-competitive
There is nothing stopping someone from forking a manifest v2 version and maintaining it. I'd argue this can't be compared to any company actually doing anti-competitive things (e.g. tractor company, printers, ice cream machine companies, etc.)
Well chrome is obvious. Firefox always triggers the same complaints about Mozilla foundation. They’re valid, but the dog pile is always very striking. At the end of the day Firefox is a great browser and has enabled a bunch of great forks all outside of the chromium ecosystem. We can be critical and should be, but again, it’s very intense sometimes. Google is clearly worse.
They doing both cleanup of Google's mess and adding their own mess. They are being criticized for the latter. Add to that that Mozilla, unlike Google, pretends to be a cleaning company when they want you to let them into your home.
Mozilla has frequently made questionable choices with its ad tie-ins and promotions. Mr. Robot ads, anyone? Unlike Chrome, Mozilla has also embedded full on data-collection schemes (Cliqz which tracked typing and browsing to test monetisation strategies).
