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.

So usually ill be playing a youtube video, and eventually the frames will stop and then firefox will crash, with the

Sorry Firefox crashed error

Now i just got a new Tablet my partner was using with no crashes and im crashing on that too, so it could be an account issue?

Already tried clearing cache and data and having no Addons Any help would be appreciated :)

Hi everyone. I hope you're doing well.

So, I've been thinking about downloading the Firefox browser for Android but I am worried.

I saw this among the app permissions on Google Play Store: "download files without notification". And I am worried.

And I need to know:

- What files does Firefox download without notification?

- Why does Firefox download files without notification?

- When does Firefox download files without notification?

- Why and how should I trust an app to the have the ability to download anything it desires at anytime it desires without my knowledge or my choice to accept or decline?

Could you please help me and tell how this app is safe?

Thanks. Have a good day!

Just a white screen today.

• Restarting device didn't help
• Settings > Apps > Firefox Nightly > Force stop didn't help

Android has an option to clear a cache, but I don't know whether that is safe. Would prefer not to clear data if possible to avoid.

Firefox crashes Android system and System UI processes after every image download.

It happens after every image download finishes.

Hi,

We use about ten Android tablets running Firefox in our shop for our employees to enter on a webpage daily some informations. Tablets are programmed to keep display active 24h/7d, firefox is pinned so the app stay opened and users don't go to other app. The extension LeechBlock NG prevent users from accessing other webistes. Everything work well except on mondays morning.

Without fault first person to try to connect on the website will see the app crash to the desktop. Since the app is pinned user will have to wait for a supervisor to come in and unpin the crashed (and invisible) app, re-launch it and pin it. Then it will work all week without issue as long as the tablet is used at least once a day. We recently added a new tablet which is used less than others and that one does crash during the week but never twice in same day. Here's the crash report that we have (I checked multiples tablets and they all share the same crash code):

Wondering if someone can help me decypher this to fix/prevent it. Is it the extension or browser itself that cause the crash if the page hasn't changed long enough? Thanks for suggestions (I will not consider "have you tried without the extension" as a valid suggestion)

I cannot even upload multiple screenshots, it is stuck at uploading. Everywhere fonts are just like this. The whole browser is unusable. I switched from Chromium and it's just giving me more and more issues here. I had to tweak dev options, config, and what not. And even after all that, now fonts are dead.

I am using three extensions: uBlock, AdGuard, and DarkReader and none of them are messing up.

On the moble browser for android I can't get websites to change from being in dark mode. I have made sure dark mode is off on the browser and the system. I have tested the same sites on other browsers to make sure it was not the sites. The browser and system are up to date.

Google homepage not loading on my mobile. Done all the recommended things, reboot, restart clear cache, uninstall, reinstall nothing works. My husband then checked his phone and it is not loading on his either. Checked for updates and there are none available. We are running 121.0.1 Any advise or hepl appreciated.

So I have installed Firefox on my Galaxy S20 Plus running Android 12. All permissions are granted and everything is working except the camera. When testing it with https://webcammictest.com/ it ask for permission to use the camera and mic. I of cause allow the use and afterwards it says: The device is not found.

I have tested the mic alone and it is working. The test site is also working in Chrome, Edge, Vivaldi and Brave. So chromium browser do not have any issue with the camera or mic. I have also tried other tests sites with the same result.

I first noticed it when I had to call my doctor which sent a link to a site with camera feedback on. I was surprised and stressed about it wasn't working. Having a doctor waiting and a sick child, while installing Chrome to get it working, was not a fun experience.

The android does not work anymore, it happened last week. I have reinstalled the app but that does not work. In the image is an example what I see when I try to open a webpage. The webpage won't begin with loading.

The Bookmarks option cannot be found on the 3-points menu, con trary to the following help topic: https://support.mozilla.org/en-US/kb/manage-bookmark-folders-firefox-android#w_create-a-new-bookmark-folder There are several options like the following three, but Bookmarks is not there: Select tabs, Share all tabs, Tabs settings, etc.

What is this issue, and how can I manage tabs folders, please? How can tabs folders be managed like making a new tabs folder or rename it?

I have noted from a web search that the subject of Javascript in Firefox (Android) has caused issues for some users of this browser.

I understand that JavaScript is now enabled by default in the standard version of Firefox (Android). It appears that once upon a time there was a config setting that could be tweaked to switch JavaScript on or off, but that setting may no longer work. Additionally, I also understand there are add-ons for the Android version of Firefox that can, amongst other things, apparently switch JavaScript on or off.

People here might be surprised to learn that the minimalist Firefox Focus (Android) browser already has a built-in, easily accessible, switch to turn JavaScript on or off:

Settings > Privacy & Security > Web Content > Block JavaScript

So, the point I would like to raise with Mozilla (but it seems to be impossible to contact them directly) is, if it is available in Firefox Focus (Android), why the heck is this switch not available in the mainstream, standard version of Firefox (Android)? It makes absolutely no sense not to have it, surely?

I would suggest that a good place to include a JavaScript switch would be in the 'Site permissions' section of Firefox (Android) settings. It is merely a suggestion as, for example, within the rather useful competitor Vivaldi (Android) browser there is such a switch located here:

Settings > WEB PAGES > Site settings > JavaScript

As for why there should be a JavaScript switch within Firefox (Android), that question is largely irrelevant. Mozilla have already seen a need to include it in Firefox Focus (Android), so what possible good reason could there be for not including it in Firefox (Android)? It mystifies me, and it's omission is an inconvenience too.

Does anyone here have a sensible answer to this question?

Hello,

Today I wanted to switch from Chrome to Firefox(103.2.0) on my mobile and after logging in everything seemed fine until I had to login into an account. I discovered that none of my saved logins have been synchronised. On desktop I use Firefox(104.0)

• I do not use a master password
• I tried to synch manually through settings
• The browsers across all platforms are up to date

How can I synch my content through my Firefox account?

Thanks.

Previously I was able to rearrange the tabs in Firefox Nightly for Android in what ever order I wanted. This appears to no longer be the case after I updated it. I am asking to see if this is a bug, or said feature was removed on purpose.
