Firefox for Android Support Forum

About:config simply shows me a blank screen.

I need to customize a few settings and I presently cannot. This question marks this as answered but the answer is talking about a solution to the specific reason they were trying to access about:config, not why they cannot access it. https://support.mozilla.org/en-US/questions/1373286

Others say to use the nightly build, which I don't want. https://support.mozilla.org/en-US/questions/1302626

What's the deal? I've spent an hour or so now looking this up and haven't found anything.

Background:

I regularly work with old modem/router at my work sites. I usually use Firefox on PC to access the management page. Sometimes, I like to check by the sites with only my phones, to mess with the configs in the modem.

I cannot access the local IP address (https://192.168.10.1/) because of the TLS requirement is too high (SSL/TLS 1.3). I need to lower the TLS version inabout:config to 1.1. I couldn't access the about:config on Firefox Android.

I have tapped 5 times on the Firefox logo to enable to Debug page, but changing TLS requirement is NOT there.

Question: Where is the setting for security.tls.version.min in Firefox Android 120.0?

I read the strings of comments regarding about:config not working and presenting a blank page. I have the same issue.

I have been a Firefox user for decades, preferring Firefox over all other browsers. However, without the ability to customize Firefox we, the loyal, may be forced to use another browser. Also, no customization is only contribution to other browser's owners/developers efforts to eliminate Firefox.

Is there a solution to fixing current version or Firefox, about:config in development or already available?

Thank you.

My Proton Mail package requires java be active. When I am browsing with Mozilla browser I am frequently re-directed to a page not requiring java. I type about:config bot get no warning and never advance to a page ro make java changes. This about maxeysf my abilities out . Help me please! Geoff in east Tennesee

Hello everybody,

Firefox v122 is running on an Android 8 tablet.

1. Are the "about:config" configuration settings still supposed inaccessible for this version?

2. Will these "about:config" configuration settings eventually become available again?

3. Is the interim solution still to install the Nightly version?

Thank you.

I have used Firefox on many systems - MacOS, Linux, Winblows and mainly Android Cellphone.

"about:config" on a Cellphone has never worked, never worked consistently, or mainly been confused with Desktop Firefox :P

Hello?!? The future is mobile not stationary desktops  :P But I digress. Please dont misunderstand me - I love FF - but when I want "about:config" on A Cellphone - I WANT IT to actually work on a freaking cellphone  :P

Is the software config too much for International Mozilla to understand? Or has Mozilla had way to much input from everyone on the planet thus watering down an otherwise great browser?

Kind of rhetorical - I know it will never be fixed in favor of locking in a dieing desktop setup  :P

In about.config i set javascript.enabled false for most browsing, unless i really need to do otherwise (e.g. ecommerce). If i close the app (menu quit), and restart it, javacript.enabled is reset true. This behaviour is not replicated for other settings i may make, e.g. dom.storage.enabled, or permissions.default.image. Being Android i have no root so no possibility of creating a user.js to override Firefox ignoring my settings. This seems to be a bug. Version is Android Nightly version 121.0a1, 2023-11-05.

I want to turn off full screen warning but every time I enter 'about : config' it serves the term and I get a page of articles related to the topic. How do I get to the advance preferences page?

in any other open tab, auto-hide addressbar/toolbar properly goes into hiding as soon as i begin scrolling, portrait or landscape.

ONLY IN AN ABOUT:CONFIG TAB, auto-hide addressbar/toolbar requires that i 1) scroll all the way to end of page and then 2) vigorously & multiply scroll down, through the stuck bar. any upward scroll & i have to start from scratch. portrait & landscape.

this Android alpha cancer has metastacized to Android beta. danged annoying.

please fix this bug & don't regress it back in.

Howdy folks, hope all is well your way...

When I download a file, a notification pops up when the download is complete. I find this quite annoying, especially when downloading file in a bit of rapid succession.

Is there some way to turn this off on FF mobile?

I tried... about:config > browser.download.alwaysOpenPanel on the nightly build, but after having created the option, it doesn't seem to work.

I would be forever indebted to any suggestions y'all can provide.

Thanks.

How do we get Firefox to load the browser tabs, which, when activated from other Android applications, diverted in the background?

The now, inaccesible, "about:config" switch" for this action is/was: "browser.tabs.loadDivertedInBackground.
