The no restart is kind of awesome. WebGPU progress is also great, even if not on Linux yet.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

webgpu makes me apprehensive. more precise fingerprinting and worse exploits could potentially be a thing.
The problem is that if Firefox does not support features like WebGPU, people will switch to Chrome once they notice web sites don't work correctly.
I guess not using it when everyone else is would be another way of fingerprinting too
yeah that's part of the issue of letting google unilaterally control the most popular browser by far.
Or, complain to the website not to use browser specific features (just like the old Internet Explorer days)
The in-memory version of the tab template prevents having to restart FF to load the new one from disk now, but, at some point you're still going to have to restart...
I tend to hibernate my laptop, so it doesn't reboot often... so surely I'm going to get to the point where FF needs a restart...
I already don't restart Firefox very often, maybe once a week, if I'm feeling like it.
Kind of neat... Don't know if really useful at all, but cool anyway
- No More Forced Restarts: This is a huge relief for many!. Firefox on Linux no longer requires a forced restart after your package manager applies an update. This means smoother, uninterrupted browsing, even during system updates.
- Reduced Memory Usage: ForkServer leads to a significant reduction in memory consumption for content processes. The base resident memory for a content process is now around 50% lower. This helps Firefox run more efficiently, especially if you have many tabs open.
- Faster Process Startup: You'll notice that content process startup times are reduced by approximately 35%. This translates to snappier new tab openings and overall improved responsiveness.
Sounds actually too good to be true to me.
Reduced Memory Usage:
This is the one that really matters. Both Chrome and FF are brutal on memory use.
That’s because each tab is sandboxed.
And cached. Browsers just use the RAM for what it exists for.
That's why my main desktop has 32GB and my laptop 16. We're at the point that these are minimum comfortable amounts.
I use Auto Tab Discard, have all except 10 tabs unloaded and FF has 5.5 GB reserved, just in case.
I have currently 13 tabs open and I don’t see the issue. RAM is there to be used. I actually expect my programs to extensively cache stuff and use the RAM.
(The other Firefox processes for the individual tabs are cut from the screenshot.)
Nah, RAM has to be reserved and can't then be used by other programs until given free. That's why, cache data and only use RAM for currently running and speed-critical stuff.
How can you only have 15 Tabs open? I'm at about a hundred at all times.
How can you only have 15 Tabs open?
I use bookmarks and close tabs I don’t need any longer.
Fellow Auto Tab Discard ejoyer, I salute you.
Joke aside I recommend this extension if you have a tendency to have a shitton of tabs opened
I for one am extremely happy about the no force restart. It's quite minor in the grand scheme of things, but it is so annoying.
True, its annoying, bit this does not take away the need for a restart of the process, obviously, just you can do it at a more convenient time.
Absolutely, it's only about convenience. I often miss the fact that firefox is in the list of all the packages that are getting updated and realize it only when I open a new tab and I get the error message, and that's annoying. Very much a first world problem for sure!
