Question Does Firefox eventually auto change about:config settings?


Hi fellow Linuxers.

If I changed or added entries in about:config (e.g. disabling dns for ipv6, other network settings, etc.) inside Firefox and those settings were no longer necessary -- would newer versions of Firefox auto change (or remove) those about:config entries?

Thanks.

Usually they don't remove normal personal choices.
Did you test and check it?
URL=about:config <Enter>
SEARCH BAR "ipv6" <Enter>
See it is only a matter of boolean. Switch it to your wish.

Of *newer versions* I assume mozilla must need choose to default in *false*.

Code:
harry@biker:~/.mozilla/firefox
$ ls
o0cnauke.default  profiles.ini  profiles.ini.bk  ynnix7nq.default-1472927979728
harry@biker:~/.mozilla/firefox
I made a backup of my profiles.ini. I run ESR Firefox so it does not update a bunch. Just security patches.

You can make a backup of your firefox folder if your concerns afear you.

Hi malekmustaq.

As far as I remember, I had ipv6 disabled in about:config -- it's enabled now. So maybe Mozilla changed this?

Hi rokytnji.

It's not that I'm afraid of forced changes -- I'd prefer changed being forced if it meant old now obsolete changes I made to about:config in the distant past were possibly degrading the performance of my Firefox.

Yes, configuration options change or become obsolete and to facilitate this "defaults" can be applied. If this didn't occur you'd potentially have a broken browser post update and would always be obliged to manually delete configuration and let it be regenerated.

However, one way to ensure that mozilla browser preferences always stick (and are portable) is to use a user.js instead of modifying via about:config (which addresses the standard prefs.js).

Hi cynwulf.

Great point about having a broken web browser. I recall a number of years back, I followed articles on how to speedup Firefox with about:config settings such as pipelining, etc. Some of these settings may be obsolete indeed.

I'm not familiar with this user.js file alternative to about:config -- I must look into it.
