Firefox Security Response to pwn2own 2025 – Mozilla Security Blog

At Mozilla, we consider security to be a paramount aspect of the web. This is why not only does Firefox have a long running bug bounty program but also mature ...

LibreWolf updated yesterday (australian time) to ....

I almost shared that yesterday. The key takeaway is that neither of the exploits made it out of Firefox's sandbox.

They still put out patches, which they have always done in this case. They once got a patch out in less than 24 hours, earning some sort of record for it.

Firefox is still the best browser around imo.

I tried LibreWolf several different times over the years didn't care for it.

I'm not a big fan of clone software of any kind.

I'll stick to the real thing.

Here is an interesting comparison of browsers over quite a large number of test variables in relation to web browser privacy: https://privacytests.org/

As expected I guess, tor, mullvad and librewolf appear to have greater success in passing the tests, but as with many things in linux, one has great freedom of choice to cater to their own preferences, interests and requirements as well as choice of the level of risk that they are comfortable with.

Even in other browsers I've noticed extensions do change settings that I've disabled.

No doubt browser extensions track user data and most likely sends that data to headquarters.

I've gotten to the point where my browser extensions are down to one uBlock Origin.

I use Firefox browser it's what I'm use to and what I like.

 

[Condobloke]

I like the way Librewolf behaves when coupled with Linux Mint 22.1 and using a couple of monitors

 

[The Duck]

I found LibreWolf as an Appimage.

I'm going to give LibreWolf another test run to see how it works installed and run OOTB.

Being it's an Appimage if I don't like it I can remove it and not traces of it ever being installed.

Just so you know I'm for real.

 

[Condobloke]

Just to add some further complexity, I am something of a browser junkie.

I believe @KGIII is also inclined that way.

I have a number of browsers installed and use different browsers for different purposes....sometimes just on a whim.

When I find one that really behaves itself, I advertise the fact here. Librewolf is one. On my setup and for my purposes it behaves admirably.

YMMV

If you mix a VPN (at the browser extension level) in here, then you're a little less easy to track. It's a way to have some compartmentalization.

Well were already off to a bad start.

LibreWolf somehow someway managed to remove every bookmark I had in Firefox.

I've heard of browsers conflicting with each other but have never had it happen until now.

It has to be something to do with LibreWolf creating a user profile which I don't have with Firefox.

I don't know.

Fortunately I'm able to reboot and have a fresh brand new install to restore my Firefox bookmarks.

I guess this can happen when different browsers with the same base are installed side by side.

This is why I don't like any kind of software clones.

@The Duck ....did you enable sync in librewolf and sign into a Firefox account to do it ?

That Firefox account should preserve bookmarks for you

I don't have a Firefox account never had any reason to create a Firefox account.

I don't no what sync does or why I would need to sync anything as I've never had to before.

Update.
Okay did some quick reading on what sync does.
No need or desire to sync anything to anything.

One of the most convenient features of Firefox is the ability to sync bookmarks across devices. By syncing your bookmarks, you can access them from any device with Firefox installed, making it easy to stay organized and keep track of your favorite websites.

I guess some folks have a use for that kind of stuff but I've never had any need for doing such.

I know folks who sync their computer with their smartphone.
One device got compromised and then the other device was compromised.

I've never found any reason to sync devices together or create browser accounts.

I appreciate the input though.

I guess I'm just to old school.

I dont use bookmarks.....so I dont tick that box, I dont use passwords either nor history, nor open tabs, nor passwords, nor payment methods.
But....I do use add ons (ublock origin & maximise all windows) and I love being able to use the same settings (a lot of thought went into the settings and I hate having to think my way through them all again)
I also choose to NOT sync with my smart phone

 

[wizardfromoz]

On Firefox Sync, re Librewolf

- in Librewolf, go to Settings - enable Firefox Sync.

I use Sync all the time, to check browser tabs in many of my other distros.

You don't have to use it for other devices if you don't want to (I don't).

BTW, may have to close then reboot Librewolf for it to take effect.

@The Duck :-

This is yet another reason why - several years ago now - I continued to further develop fredx181's original concept of the Puppy-portables. The portable browsers, in particular, are able to totally compartmentalize every aspect of their operation.....to the point where I can have FF, FFesr, LibreWolf, SeaMonkey, Midori AND Pale Moon - all 'zilla-based browsers - simultaneously running alongside each other, all at the same time.

No interference, no cross-contamination, no 'poaching' profile data of any kind from each other. You try doing this with a conventional setup.

It simply won't work. FF & FFesr, in particular, really dislike each other running at the same time....

(shrug...)

You got that right as those browsers were the ones I read the most complaints about conflict with one another.

librewolf is easy to install on Debian , just use extrepo.
sudo extrepo enable librewolf
sudo apt update
sudo apt install librewolf

It creates it's own profile and doesn't mess with Firefox/Firefox-beta profiles.

I have Firefox, Firefox-beta installed using the Mozilla repo, Zen using appimage, Librewolf , Vivaldi and Chromium.

Not sure why I bother installing anything other than Firefox I hardly ever run any other browser.
