In the case of Firefox profiles maybe I can actually provide some useful info this time.
"firefox -ProfileManager" brings up the GUI profile manager and "firefox -P [profile name]" boots a particular profile.
Anyway, good luck.
Sorry, I've never tried to revert a package but I "think" synaptic can revert packages (system or otherwise) and shared it because I wanted to make sure it works on Linux mint. Maybe I should have clarified that's more of a "best guess" on my part than something I'm sure of.
The risk of rolling it back is even if brave works fine with an older version, if a different piece of software was tested with the newer version and expects it you could end up with a situation where other pieces of software that depend on it either break or keep trying to force you to update.
If you have a system backup and all you're risking is time then I'd say go for it, just wanted to bring up the potential risks and some other options as well.
You could check synaptic package manager to maybe see about rolling it back https://forums.linuxmint.com/viewtopic.php?t=179192
Though keep in mind that trying to roll back a particular dependency couldbee a good way to run into problem's.
You could also try re-install Brave and/or try installing as a flatpak to see if those fix it without rolling back
It's between XFCE for it's simplicity and KDE for it's Wayland support for me
My understanding is that it's not really the disrto, but the software running on it that'd effect battery life and performance. Both Debian and Arch can come pretty bare bones on a blank install (Ubuntu and derivatives tend to come with a fair bit of stuff bundled out of the box).
I'd personally reccomend trying a Debian installation (I'd likely say use stable, but testing or sid are also options if you need quicker updates and don't care for flatpak/snap/appimage/distrobox). The installer plays nice with Windows, and you can skip installing a desktop during installation then CLI install a tiling window manager to really minimize 'bloat'.
One word: Mint
It's pretty streamlined, more reliable than some newer trendy Ubuntu spin offs, and still powered at it's core by the same old kernal that even the "advanced" distros use.
I applaud you for trying Arch, and if you can figure it out while learning Linux in general that's a great achievement, but it's overly complicated and I personally wouldn't reccemend it to anyone starting out (or even a most experienced users unless they had a particular need for it's features).
If you continuously get issues across all distros in VMs a live environment might also be worth checking out (live being booted off external media without an install).
Ultimately, though if Linux does mess with your workflow, then use what works best for you. Sure I like Linux, but if it breaks what you need and Windows or Mac doesn't then use what works best for you. But, there's a saying "the more the island of my knowledge grows the greater the shore of my ignorance". The more you learn the more that you realized how little you know. It's always the case for anybody who's either not an extreme expert or a narcissistic, but it's also a great motivator to keep learning.
Cool! When you say you requested to subscribe, does that mean the server needs to federate or does that mean I accidentally set it up in a way that subscribers need to be approved? If it's the latter I definitely need to change that
