After playing around with this for a bit I found a few things that are deal breakers for me:
Even syncing with Xmarks bookmark sync, which will sync without dupes in the lastest snapshot, will not sync the favicons. Some may see this as a quibble but I like having the favicons and being able to refresh them without spending a couple of days doing it. I have over 250 bookmarks. Perhaps half of those are in the Bookmarks Bar folder structure. It just makes it easier to see what is what with the icons.
On startup, whether opening to a blank page or to a Speed Dial there seems to be a hesitation before it will accept input. This is the main reason I cannot tolerate Firefox as my goto browser anymore. Firefox is even worse with a 20 to 30 second lag before I can type into the address bar.
The forum moderators use condescension when they cannot defend the product with rational argument. I have no need to waste my time snit picking with those who want to impart spin to the issues.
What I have found is that the SlimJet Portable browser I have been using as a backup browser has qualities that have come to the fore recently:
1) Xmarks bookmark sync or importing a bookmarks.html from Firefox seems to get the favicons without making it a life's work.
2) I notice that even though I have it set to start with Fast Dial rather than a blank page, when I open the browser via clicking the link or by launching a url, the dial does not hamper the browser loading. It snaps right up there and will accept a url typed into the address bar.
3) The auto check for updates seems to work even though this is the portable version of the browser. Edit: maybe because it is a major version update it did no sense 10.0.1.0 update available yesterday.
4) I signed up for the SlimJet Forum. But I just checked and clicking Browse Your Posts shows a total of 0. So I haven't had to badger anyone over there to get something working.
I like using Firefox and am used to it. But the performance issues are so annoying now that I have to relegate it to backup browser status. Unless they break it, SlimJet seems to be one of the more well thought out chrome implementations.
The UI was kind of appealing but I have uninstalled Vivaldi as just not being close to ready for prime time.
