For a while now the transition away from Manifest V2 (MV2) to MV3 has been on-going and it looks like it is entering its final phase of deprecation, at least, in the case of Google Chrome. A recent discussion thread in the w3c WebExtensions Community Group GitHub repo has highlighted how the latest and upcoming versions of the most popular browser are expected to be its final releases with support for MV2 extensions.
What this essentially means is that the tricks and bypasses that were used to keep MV2 extensions like uBlock Origin and others alive will not work any more on Chrome, or at least not for very long. For example the Windows Registry mod that could extend MV2 availability will cease to function after Chromium version 151.
Not sure what your daily browsing is like but Firefox is notably slower across numerous sites than Chrome. And absolutely non-functional for some sites for me.
I mean don't get me wrong, I use Firefox as much as damn near possible. But that's maybe....50% of sites with parity and 25% more if I'm OK with a degraded experience.
I'm curious to know. I mean, I typically have dozens and dozens of tabs open and never shut my computer off. Curious what these numerous sites are, you're the only one that can attest to that.
Bill pay sites, banking sites, news sites, intranet sites.
I was being generous in FF favor with 25% because I truly love it and use it even with the issues, but it is a daily problem for me for sure.
And this is across two laptops, a desktop, a Linux system, and my phone.
Strange. No issue here in shitty windows 11 on a lenovo laptop or on my 2019 desktop running Linux. Similar site usage, and some sites I use are using 1GB of RAM each.
But which are these specific sites, as in some exact domains? Why are you avoiding naming them?
See my other comments, I've named some and given examples.
