I wanted to keep using FF despite being a gmail user so much so that I switched to Thunderbird for my emails. I guess Mozilla wins this way.

I thought Thunderbird was not under development anymore?

They released a new version on the 27th of August[1]. It looks like it that was the first release since August 2018[2].

It is mostly par with Chrome now pretty much everywhere. Well browsing most website should not trigger lag in any browsers. But if we look at benchmarcks: https://www.phoronix.com/scan.php?page=news_item&px=Firefox-...

Does anyone know if those same phoronix tests have been run against the new Firefox 70 Nightly or Developer Edition apps? I'd be curious to see how 68 versus 69 versus 70 compare.

I don't think it has yet been done. But as you probably noticed he tested with webrender too

It does on Windows and Mac. On Linux it does not but hopefully WebRender should pave the way to enabling it (see https://bugzilla.mozilla.org/show_bug.cgi?id=1210726 ).

When chrome slows down for me, it normally means I need to run clear browsing history, delete cookies, cache, logins, etc. I have modern hardware, on both linux/windows same issue. But using res on reddit and click "show images" you can tell chrome isn't as fast as other browsers, firefox/brave are visually faster/smoother in scrolling with pics. Hell, even firefox focus is faster on android. But I like chrome addons…

Sync with my mobile and all the other devices (4 other computers) is one reason why I use Firefox. It's because it's the only browser, as far as I know, which lets me run my own sync server and offers a open source implementation of it. https://jeena.net/firefox-sync-15

Oh neat, when they first switched to sync that wasn't the case (the previous system did allow it over WebDAV and such), but because sync wasn't just a data dump with WebDAV it wasn't possible at launch to run your own server. I'll have to look into that again.

Something is still extremely funky with video on macOS Firefox. Playing MP4s on YouTube still uses 200-400% more power than on Safari, and that's with transparent window disabled. Hell, Twitch turns my 2015 MBP into a vacuum cleaner but Safari barely breaks a sweat.

I have the opposite experience with YouTube. With an AMD GPU on Linux, Chrome churns, drops frames, and stutters horribly on even 1080p videos at 30fps. Firefox, meanwhile, handles 1440p60 video with no problem. Even two such videos simultaneously, on separate monitors. Chrome became inexplicably better for parts of early 2019 (I did not note which versions), but starting 2 or 3 months ago Chrome returned to being un…

Hey, I'm on the chromium videostack team, would you mind filing a bug report for what you see happening with youtube? https://bugs.chromium.org/p/chromium/issues/entry

I will take a look this weekend and if I can properly explain and document the issue in detail, I will definitely give you everything I can.

I should add that for an identical Linux distro-and-version, and identical browser versions, my laptop (I forget the SKU, but Intel Broadwell U-series GPU) is about equal in performance between Chrome and Firefox. That is to say, 1440p60 runs smooth on each, so they're good enough that there's no issue from which to discern a difference (which is damned impressive for a 4-year old mobile chip, imo).

Gmail is really crazy slow on Firefox, it’s such a deal breaker. I have regularly 30s to load the web application, it’s closer to 2-5s on Edge with the same setup (same ad blockers, etc).

Google should get their shit together and make Gmail usable then. (Works fine for me in FF though).

Also, please tell your coworkers to fix Gmail so that it works fine for users experiencing problems in browsers other than your own. Thank you!

Check about:gpu - sounds like hardware acceleration isn't working.

It seems intentionally disabled. The about:gpu page reports the following:

>Accelerated video decode is unavailable on Linux: [137247](https://bugs.chromium.org/p/chromium/issues/detail?id=137247)

>Disabled Features: accelerated_video_decode

I suspect this is because chrome supports WebSQL while Firefox does not.
