Firefox Download Options

Normally, web pages are displayed in the default font set by your browser or in a font chosen by the web pages' authors. Here, you can select the font and font size used when web pages don't specify one. For more advanced font options, click on Advanced..., or for colors options, click on Colors....
Web Feeds are specially formatted documents which summarize the content of web sites. You can view the content of feeds in Firefox, create Live Bookmarks for them, or add them to a feed reader on your computer or on the Web. The options in this pane determine what Firefox does when you view a feed.
This option controls whether or not past downloads show up in the Downloads window. The Downloads window (accessible from the Tools menu or by pressing Ctrl+J) displays a list of your recent downloads. Downloads options are available in the Main panel.
If you wish to clear your private data right now, you can click the Clear Now... button to do so. To clear your private data from outside the options dialog, either press Ctrl+Shift+Del or select Tools > Clear Private Data....
The HTTP OPTIONS method requests permitted communication options for a given URL or server. A client can specify a URL with this method, or an asterisk (*) to refer to the entire server.
The choice of which Mozilla project to build and other configurationoptions can be configured in a mozconfig file. (It is possible tomanually call configure with command-line options, but this is notrecommended). The mozconfig file should be in your source directory(that is, /mozilla-central/mozconfig).
Calling the file .mozconfig (with a leading dot) is alsosupported, but this is not recommended because it may make the fileharder to find. This will also help when troubleshooting becausepeople will want to know which build options you have selected andwill assume that you have put them in your mozconfig file.
Be aware that changing your mozconfig will require the configureprocess to be rerun and therefore the build will take considerablylonger, so if you find yourself changing the same options regularly, itmay be worth having a separate mozconfig for each. The main downsideof this is that each objdir will take up a significant amount of spaceon disk.
The build options you choose depends on what project you arebuilding and what you will be using the build for. If you want to usethe build regularly, you will want a release build without extradebugging information; if you are a developer who wants to hack thesource code, you probably want a non-optimized build with extradebugging macros.
There are many options recognized by the configure script which arespecial-purpose options intended for embedders or other specialsituations, and should not be used to build the full suite/XULprojects. The full list of options can be obtained by running./mach configure -- --help.
Chooses particular compiler optimization options. In most cases, thiswill not give the desired results, unless you know the Mozillacodebase very well; note, however, that if you are building with theMicrosoft compilers, you probably do want this as -O1 willoptimize for size, unlike GCC.
Hey guys (and galls too), could anyone help me out on how to block access to Firefox options? I'm setting a public computer and don't want users to change anything, or at least to prevent accessing as much settings as possible.
I thought I would start small and set the default homepage using one of the config files but so far I can't get firefox to acknowledge any of my changes regardless of where I put them. My basic test has been this:
Firefox generally reads its settings from /.mozilla/firefox, so if you have the settings in a shared location, once that folder has been created, Firefox will ignore your shared settings. What you could do however is take a look at the addon xulet-ubufox used by Ubuntu to modify Firefox settings (it is installed by default), and see how that gets it done.
Another option, if the systems do not yet have user accounts set up (or if you can recreate the accounts), is to put a customized /.mozilla/firefox folder in /etc/skel. This will be copied to all new accounts.
A third, possibly easier option, is to create the customized defaults, package them in a deb that points to some shared location like /usr/share/firefox-defaults, and then copy these settings on startup (of the user profiles) to /.mozilla/firefox. I don't know the full technical details of accomplishing this, but I believe it should be possible to do it by adding something to /etc/rc.local
But some of the more advanced configuration options aren't available to change there - instead you need to open the special "Advanced Configuration Editor" screen in Firefox and locate the setting you want to change.
Because about:config will give you lots of advanced options which can potentially mess up Firefox, you will be warned about not changing anything you're not sure about. Click the "Accept the Risk and Continue" button.
You can use the Search preference name box to find the setting you want to change, or alternatively you can click Show All to see a huge listing of all the options and then scroll through them to find the setting to change.
Step 5) Inside of the firefox.cfg file, you will want to create a structure simpler to the following:(*Note: I have chose to use lockpref as it will lock the preference from the user being able to change it in about:config, if you do not use lock in front of pref, the user can still change it)
Even though I don't actually use the Firefox Home view, I still disable all options under Firefox Home Content. This is wholly unneccessary though, but should I ever use a rogue keyboard shortcut or mis-click and have the page open, nothing unneccessary will load in at least.
What new cleaning options are available for Mozilla Firefox, and does this only apply to the Mozilla Firefox Universal Windows Platform (UWP) app available on the Microsoft Store? I just launched CCleaner Free Portable v6.10.10347 (using the same ccleaner.ini file that I was using for the previous v6.09.10300) and can't see any new options for the Custom Clean feature at Applications tab Firefox, and when I click the "Analyze" button it doesn't appear that any new items will be cleaned for my desktop version of the Firefox v111 browser.
I've been following FlyHigh's 15-Mar-2023 topic 6.10.10347 about how the "expanded cleaning with 23 new options" in CCleaner v6.10 is starting some Windows services like the TeamViewer service to perform new cleaning tasks even if the user has deliberately configured the service not to run at boot-up, and I want to make sure that CCleaner v6.10 isn't doing something to my Firefox browser that it shouldn't be doing before I actually click "Run CCleaner" and allow it clean my system.
This isn't the first time that Avast / Piriform has added and automatically enabled new cleaning options that unexpectedly deleted data or made some change that users didn't want (see my 20-Feb-2022 thread Question RE: New Windows SubSystems Temp Files Cleaning in Cleaner v5.90 for another example). I could see why they might do this for the Health Check feature - that's one of the risks of using this type of "one size fits all" one-click cleaner - but a user's Custom Clean settings should never be changed without their permission.

I deliberately @mentioned employee @johnccleaner because I was hoping they would be able to get the information I was seeking directly from the software developers who added the new Firefox cleaning options. CCleaner has damaged Firefox installations in the past because their QA team apparently does not test the potential effect of CCleaner on nightly/aurora/beta releases of Firefox before new (stable) Firefox versions are released to the general public (see my 03-Aug-2020 post in circcc's Problem with Firefox 79 ) so I'm always wary when Piriform / Avast makes any changes to Firefox cleaning.

Firefox has a debugging protocol that allows scripts to drive its DevTools from remotely. There are libraries such as node-firefox and foxdriver that use this protocol to remotely debug websites, fetch their logs, etc. For security reasons, the remote debugging protocol is not enabled by default, but can be enabled in preferences or from the command line:
@whoami - if you want NON disposable qubes to be so configured, then you
can do this:
Open firefox and configure it as you will, (in a normal qube).
qvm-copy .mozilla to a template.
In the template, move the .mozilla folder in to /etc/skel
qubeA:
Check which firefox profile you are using - in firefox type
about:profiles in address bar.
You will see the name of the profile in use: remember it.
Close down firefox.
qvm-copy the .mozilla folder to qubeB
Thanks, I was focused on disposables, and totally forgot the switch at the moment. Right after the post, I did it simply overwriting the content of the default profile firefox folder with the content of the customized one.
