Firefox survival guide

Besides causing issues with setting FireFox as the default browser this might also lead to other problems and stability issues as it is a setting intended for use with sandboxed app formats likes Flatpak or Snap (it does the same as launching FireFox with GTK_USE_PORTAL=1 IIRC).

Maybe one day we will actually get proper support for native KDE Plasma dialogs in FireFox out of the box ...

[deleted] thanks, ill keep an eye out for trouble. nothing so far

So far it looks like most of the glitches have been fixed when that setting is enabled (except for asking to be set as default browser when it already is).

Setting "GTK_USE_PORTAL=1" on the other hand now forces my FireFox to use Adwaita as GTK theme / cursor theme on Plasma not respecting the GTK theme set in the Plasma settings ...

Not Sure this has been shared before, firefox related tweaks can be found in the Arch wiki.

Firefox Profilemaker
Firefox Profilemaker is a new online tool that helps you create custom Firefox installations. To be precise, it can be used to customize Firefox profiles, e.g. to block Telemetry, enable Enterprise policies or configure browser features.
https://ffprofile.com/
info via https://www.ghacks.net/2021/11/05/create-custom-firefox-installations-with-firefox-profilemaker/

note: the policies.json from the enterprise policies zip should go into /usr/lib64/firefox/distribution
this folder normally doesent exist on solus so u gotta make it ( sudo mkdir /usr/lib64/firefox/distribution )

Lucien_Lachance ghacks liked the idea of it while saying in another sentence it will never be as comprehensive as their famous arkenfox.js......but just when everyone wants to throw in the towel with firefox they offer another tool for another layer of privacy for the person who wants it fast and easy and not have to tear into about:config. That's a good thing, btw.
2 cents: I can get a lot accomplished in about:config ; I have a comfort zone with it

brent i have like 12 firefox profiles for various things ( for example a separate one for twitter) - the enterprise policy approach is really handy as it affects ALL profiles

brent

Lucien_Lachance That's interesting. I would like to try a couple. Right now I have firefox configured to FPI (first party isolate) all cookies which is lo-tech, but an experiment.
Do you use a new profile per tab? Or per window? Or does it matter?

Lucien_Lachance

brent nah just one for regular browsing, another for net banking, another for twitter, another for gmail,another for another gmail account,another for twitch (as i wasnt able to use twitch with my regular profile, too high security settings i guess, couldnt figure it out) and so on, just things i want to keep separate. never got around to learnign about containers and such as this system works well for me, and with separate .desktop files for the profiles they can have different icons in taskbar as well

There's a great website with custom Firefox CSS themes.

https://firefoxcss-store.github.io/

I applied the Simple Oneliner CSS theme and made a few tweaks to it.

Here's how it looks.

The extra vertical space is great.
Here are the instructions on how to apply the CSS themes.

Junglist nice find! About 40 of these things? With some of these themes it seemed horizontal was freed up as well but that can't be possible (since width is decided by user).
I'm narrowing: australic proton, gradient rounded, and pseudo fullscreen.
The instructions are nice and hacky, wonder if removing is as simple as just installing another theme from FF store? What a creative gallery of firefox looks.

Junglist

brent Removing it is just a case of deleting the chrome folder [you created inside your Firefox profile directory] containing the userChrome.css and userContent.css files.

I am curious to know if Fission is enabled(by default) for anyone here.Mozilla said it would be made available to everyone in Firefox 95.For me, it is still disabled. maybe the fission rollout is not complete yet i guess...

[deleted]

It is still a staged roll out AFAIK. So not everyone is getting it at the same time.

For me it was enabled automatically without doing anything (at least according to about:config and about:support).

According to (https://www.dz-techs.com/en/first-party-isolation-firefox), "In short, First-Party Isolation (FPI) limits access to cookies, cache, and similar data to the domain level only. This means that when FPI is enabled, advertising agencies cannot use cookies to track your online activity while browsing the web." FF introduced this option not long ago.
Of course I read a lot more than this and in my guesstimation this is for people who would rather put their cookies in containers, rather than use Containers.
I've been giving it a go....the sad part is there is no way possible to know this works unless you have forensics kung fu.
Omitted: the 2 or so about:config moves you have to make for this. Easy to find.

To add a custom search engine to the built-in list and be able to set it as your default engine:

Open about:config from the address bar
Create browser.urlbar.update2.engineAliasRefresh as a new Boolean preference
Set it to true. This will display an Add button on about:preferences#search
