I really like the goals they picked, but wish "Native Look and feel" was also in there. I use Firefox as my primary browser on Windows, but on the Mac it still feels significantly non-native. For instance, we're still missing rubber-band scrolling, Firefox still doesn't set the file attribute that causes the progress bars to be displayed on the Finder for each file and on the Downloads stack on the dock, on full screen the toolbar doesn't 'move down' along with the menu bar when I move my cursor to the top of the screen, there is still no pinch to zoom, the back/forward trackpad gestures and checkboxes/radio buttons are not animated, etc.
I love Firefox and it is my primary browser for years, on both - Mac and Windows, and it's not going to change anytime soon. Still, I feel Mac version is noticeably slower. Even though I disabled all extensions I can see the difference between Chrome and Firefox on Mac. Sometimes I can even see "naked" plain text page for a moment, before styling is applied (ex: on GitHub pages.)
This is called "Flash of unstyled content", and has been a bug since 57: https://bugzilla.mozilla.org/show_bug.cgi?id=1404468 . In 57 the delay before initial drawing was removed, which mostly makes things feel faster, but sometimes makes things show up naked for a moment.
In that bug you can see there are several things that can cause this, including website issues and certain extensions.
A bug report with steps to reproduce (even a link to the specific GitHub page involved would help) would be really useful if you are still seeing this. Please cc "bzbarsky". Also worth checking whether the problem persists with extensions disabled, if it's reproducible enough to do that with...
Yes, that one is on my to-investigate list already. Thank you for the reminder!
Chrome has started just blocking the HTML parser completely on stylesheets. That means it doesn't end up with FOUC (except insofar as there is renderable content before a sheet that is affected by the sheet), but at the cost of less parallelism and slower pageload...
I’ve been tracking some of the bugs related to this for years, and there’s been a dispiriting lack of progress in them. Ultimately I’m still a Firefox user because it makes the best trade offs for my particular wants and needs, but I’d love to be able to more enthusiasticallt recommend it to others for whom non-native feeling apps are a non-starter.
I would like to use Firefox but I still use Chrome as my main browser. Edge, in fact, is my secondary browser (I'm on windows) and I use Firefox last. The speed of Firefox is much better than before but it's appearance is very clunky, enough that this is the main reason I don't use it. There are also other ways the browser seems to lack polish. I don't say this as an attack. I see so many fawning comments about Firefox so I want to give my honest opinion.
A clunky appearance is a fairly subjective statement, could you clarify exactly what about the appearance doesn't work for you? I think that would provide somewhat more useful feedback. (I use Firefox on Windows, and personally don't view it as any more or less clunky than Chrome)
