I see a lot of comments (justifiably) touting firefox's superiority... but the performance difference is night and day.
My main pc has very weak hardware, and my browser is the most resource intensive application I run. In my environment, I can't leave firefox open with other heavy apps running simultaneously, but I can leave chrome open.
I've used firefox for decades in the past, but the gap is huge and it doesn't look like Mozilla will make the engine changes necessary to close it. Idk if things have changed, but I remember when they axed the Servo team.
I've been using Ungoogled Chromium and I'm hoping this doesn't affect me for a while... but if I have to choose between ads and closing my browser to run heavy apps, I guess I'll be reinstalling firefox.
Performance night and day? I don't think so lol. I daily Firefox. It works fine.
And even if it didn't and it was slower.... I'll take slower over all those fucking shit ads
Yeah, of course ads aren't an option, but ungoogled chromium still supports mv2 for now and I can't watch a youtube video and play a video game at the same time with firefox on my machine...
Granted, I'm probably trying to make inadequate hardware do more than it should, but chromium works and I don't want to upgrade my hardware right now.
Now this in curious about. Why can't you do both at once?
I daily game with Firefox and dozens of tabs open. Granted in using Linux.
Youtube is especially egregious. I've tried various hardware acceleration settings and h264ify but it really brings my pc to its knees.
Im on linux, and when I run my windows vm (qemu kvm) with either Visual Studio, SQL Server Management Studio, or Fusion 360 in it, firefox on my host machine runnimg youtube just barely pushes it over the edge.
I absolutely recognize how wild what I'm asking this little computer to do is, but I can just get away with it in chromium but not firefox (since the last time I checked)
The day I can do it all with firefox I will be a happy camper
Edit: also, I specifically said games but didn't name one... FFXIV and Deadlock both crash if I'm running youtube in chrome (and Discord at the same time).
I play elden ring, nightreign, harry Potter Hogwarts legacy, doom 2016 and eternal and a whole bunch of other shit. No issues.
Also use YouTube. No issues.
Are you using open source video drivers perhaps?
I'm using an AMD APU, so just the regular mesa drivers.
The last time I had issues was about a year and a half ago, and I switched to Brave, but a year later (5 months ago) I was convinced to give Ungoogled Chromium another chance by someone here on lemmy (because of all the controversy surrounding Brave).
In the past I always used firefox because its customization features are so much richer, settings werent intrinsically tied to google (or amputated like in ungoogled), and the source code is more comprehensible (firefox is so neatly organized and easy to build yourself, and chromium is a giant mess under the hood).
I really want to use firefox again... maybe I'll get a dell precision tower off ebay and shove a cheap old nvidia card in it with the proprietary drivers to solve my problems 😅
I've been on nvidia forever at this point. Personally looking forward to getting back to AMD next time around. They are more open with their drivers. You should try the AMD proprietary drivers instead.
Hey I know it's been months, but after the discussion in this thread I built a new computer with a real GPU (I went AMD and I'm using the MESA drivers) and tons of ram, and I am happily running LibreWolf and it's awesome!
In terms of ram utilization and GPU acceleration on this new machine with modern hardware, Firefox is negligible, as everyone told me it would be!
