I just opened my gmail in Firefox and I don't see this Chrome notification right now. Maybe it pops up every now and then. I wouldn't be bothered by it that much, since started using Thunderbird as mail client last month, and the interface is so much better and customizable than gmail ever was. I did use Thunderbird a long time ago, but stopped when I got gmail in 2004. And all this time I thought Thunderbird still had the old classic UI. Apparently it became a bit too messy with all different volunteer contributions and Mozilla didn't have a project management to stay with a certain direction. In Feb 2023 they announced in this blog post to rebuild Thunderbird from the ground up and invest the resources to support the community again, although with more control. Then a few months ago this big update to 115 was released, which was featured in a computer tech website so I became curious again. One of the best decisions of this year (although I'm still using it to access gmail), together with joining Lemmy of course.
