Please I want to remove Ai from Firefox Mozila permanently on Windows 11 for all users/profiles:

I tried a lot of workarounds but they are unsuccessfully: I tried to create extensions (Hide Gemini, AI Google Overview), but they do not work for all users; only profile-based extensions are supported. I tried to use preferences using internal settings on Firefox, but it does not apply to all users. I tried using a script on PowerShell for all users merging internal preferences, but it does not work I copied the local and roaming settings from Firefox to the Default profile, but it was unsuccessful.

I also tried to remove "All" from the search page, but I moved the seach to go to the tab "Web" only.

Thank you for any help and feedbacks. --Rod

When I click on Bookmarks, all I see are the following:

Manage bookmarks Bookmark current tab Bookmark all tabs

Bookmarks Toolbar Other bookmarks

What happened to the entry that shows my bookmarks ?

i can change font size in general via firefox settings, BUT!

whenever i want to download a file from any given website,
the download window that appears, in which i can navigate to a folder on my computer and choose a name for the file,

has such super small font!!! and to make it worse, the text largely in a soft gray rather than a nice strong black! SO hard to read. i would love an easy way to make this font always bigger for all these situations. if anyone can provide the solution im super grateful!

I do not and will not use the sidebar/vertical tabs features.

Unfortunately, it seems that firefox has decided to reactivate these features with an update? This is unacceptable. I do not want my settings to be altered with a software update. If firefox wants to tell me about a new feature, feel free to make a dialogue bubble pop up (once) asking if I'd like to explore said new features. Otherwise, please refrain from altering my preferred configuration without permission or notification. Doing so is completely asinine at best and shows open contempt for your customer base at worst.

I do not wish to give mozilla/firefox another opportunity to make my experience worse, thusly I ask: Is there anyway to entirely remove/disable the sidebar/vertical tabs feature from the browser so that it cannot be reactivated without the specific actions of the user?

We want to use Firefox on a locked down system where the user will not be able to go to other websites. We looked at using Kiosk mode, but we want to allow tabs. How can we hide the address bar before the browser is opened and without registry changes?

It nags me, that I ain't asked if I want the AI function, you just force it over me without giving me any choice, if I want it..

SO, how to COMPLETELY remove the AI function in Firefox and Linux Ubuntu..

AI scare me and I definitely don't want ANY of it!!!

When I want to access a site, I am told JavaScript needs to be enabled for access. In checking I am told JavaScript is already enabled. To check it, I should about:config in Firefox mobile and toggle JavaScript to true if it is shown as disabled. However, when I do that I am blocked for safety reasons. I want to know what's happening here with JavaScript and Firefox mobile.

As the question stated I have navigated to my mozilla profile folder, ( C:\Users\User\AppData\Roaming\Mozilla\Firefox\Profiles\pw1dnvcy.default-release ) but there is no file called persdict.dat. I have ensured all file name extensions are visible, & none are hidden in windows file explorer (Win 10). I am at al loss I cannot figure this out.

Updated recently from (I believe) 138.04 to 139.0.1, and immediately noticed that the size of font (and icons) had changed in the folders I have in the bookmark toolbar, that is they are much smaller and thus also less space between. Why this, and is it possible to change the size, without changing something else?

It's possible that many don't have folders in the toolbar and thus don't notice, but I have 2-3 apart from bookmarks.

I remember a change many versions ago that increased the space between entries in the bookmark menu, and also in the bookmark toolbar folders. That was too much and I found a setting [in config] that could be changed to decrease the space back then. (I haven't looked for that solution now, probably have some doc somewhere, and won't bother searching since this is different. Same with this case; I did some quick initial search but found next to nothing and older. BTW, this is one of the downsides of changes like these and similar; the day you have too move to another OS version, i.e. reinstall everything you also have to keep documentation of all these little changes, apart from all the other things you'll have to export or save.)

Back around February (2025), the full screen mode by pressing F11 quit working. Clicking the diagonal two pointed arrow in the application menu didn't do it anymore either. Both actions only toggle the bookmark bar. I've tried reinstalling, and waiting for further updates. So far, still no luck. I've since moved on to using another browser, since I often want this feature. Does anyone have the same problem or know how to fix this?
