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?

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 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.

I need to reach the about:config menu but firefox takes me to a search menu on the engine I chose (duckduckgo). It provides lots of nice info but not how to reach this feature.

I am using Chrome OS so possibly that is the issue.

Thanks!

I updated and now "Settings" & "Quit" aren't in the ︙menu. They're hidden and I have to swipe up a second time to see them. This interferes with my workflow, as I use "Quit" dozens of times a day and it used to be effortlessly accessible via a single finger flick.

How do disable this hiding of "Setting" and "Quit"? Is there an about:config option I can toggle?

I am using Iceraven-2.23.1 (Build #2016045162), which is based on Firefox for Android and allows all users to use about:config

(If there is no about:config to disable it, let me know the last version before this was changed, and I'll use that instead.)

¿Existe un Manual de Instrucciones completo y detallado de las opciones "about:config" que permite Firefox en Android?

1. Si existe, ¿dónde está?

2. Si no existe, ¿hay en marcha algún proyecto para su creación?

Typing about:config in the address bar does not bring up a list of configuration files. All it does is produce a google search list of YouTube and Mozilla help sites. How can I access Firefox configuration files so I can stop websites from refreshing?

Hello guys !!

I wanted to disable the prefetching/preloaad pages and I found some entries on about:config that I had to change. Some of those are here on the official support site and some not, I found them on another forum.

Here's the list: network.prefetch-next (false)

network.dns.disablePrefetch (false)

network.dns.disablePrefetch.FromHTTPS (false)

network.http.speculative-parallel-limit (0)

browser.urlbar.speculativeConnect.enabled (false)

So, my questions are: 1. All these expect one "browser.urlbar.speculativeConnect.enabled" are available on android (nightly). Is there and i can't find it or it's indeed not available ??

2. Is the "network.http.speculative-parallel-limit" works only for http or it works and for https as well ?? Is there some setting to geti it to work for https if it doesn't ??

3. Is true that the "network.dns.disablePrefetch" and/or "network.dns.disablePrefetch.FromHTTPS" doesn't work (if i disable it) if i have turned on the dns over https ??

4. Are there other settings that I need to configurate or I'm good with these ??

Thanks in advance !!

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
