Firefox for Android Community Forum

As the title says, I got a problem with Android version of Firefox that sometimes on some webpages it just hangs and doesn't load the page at all. While it's hanging there if i try to open extension settings it doesn't even load that, just opens blank page. Only way around it is to close tab and try again later. Sometimes i can just close tab and on next try it works, sometimes it just doesn't. I've had same issue with PC version of Firefox and it seems to be fixed after disabling HTTPS over DNS. On Android I've tried changing network.trr.mode to 5 but with no luck. Also ive tried disabling extensions and changing some options but whatever I do it just still keeps happening. Btw its a new install after years of not using Firefox, perhaps because of the same issue.

There is a certain wiki site I visit which changes it's theme based on the game the wiki is about. I'm trying to change the color of the links on the website because they are the same color as the text so it's impossible to see which are links. I want to change only this websites link/text color.

I have opened about:config and tweaked browser.anchor_color

browser.visited_color.

This doesn't change the website link color im trying to change because the site sets it's own color for links and text.

Assuming it works the same on mobile as on the desktop, these color settings only get applied when a site doesn't define its own colors (i. e. basically never nowadays) - unless you explicitly set Firefox to override the sites' settings (`browser.display.document_color_use` set to "2", which corresponds to selecting "Always" from the dropdown menu in the color settings).

When playing YouTube videos in full screen using

Firefox: the gear button and the "restore screen size/exit full screen" button are nonfunctional (nothing happens when I tap on them).

Google Chrome browser: the gear icon button is nonfunctional.

DuckDuckGo browser: the gear icon button is non functional.

Opera browser: the gear icon button is non functional.

This problem started about a week and a half ago.

I'm using version 129 of Firefox for Android on a Galaxy S23+. I've used Microsoft Authenticator before to sign into Firefox Sync and Firefox Account.

Today it won't accept the MS Authenticator code. I also tried one of the backup codes and that didn't work either.

With either option above that I tried, I'm directed to a screen that reads: "Did you use the system camera? You must pair from within a Firefox app." This is the URL: https://accounts.firefox.com/pair/unsupported?showReactApp=true&deviceId=1eb2f6829ea748a4b9975e16e8584e74&flowBeginTime=1722955970609&flowId=ab2a1ddc80b9a6e6b68e2b7f20ce7546f5333f91d6a63712eaa4c4860f21d0c0&context=fx_desktop_v3&entrypoint=preferences&service=sync&uid=581fc07c2eb44d6ba8b28f9398cde1ce&prefillEmail=ezrway%40gmail.com&email=abeeler2489%40gmail.com&hasLinkedAccount=false&hasPassword=true&showSuccessMessage=true

There are no other options on this page. I attached a screenshot.

Thanks in advance! Andrew

Firefox Sync is not working appropriately insofar as, when I check Firefox on my Windows 11 desktop, I cannot see any tabs being synced from the Firefox app on my Android phone, even though both apps are logged into the same Firefox account and syncing open tabs is enabled on both machines.

However, when I check my phone, I can see all the tabs synced from my desktop. So, this seems to suggest that the sync process is working correctly on both desktop and mobile because I can actually see all the tabs that are open on my desktop, but I cannot see any of the tabs that are open my Android.

Everything is checked to sync on both the Windows and the Android Firefoxes.

Has anyone encountered a situation like this before, where sync is working appropriately, but one device seems to be refusing to upload specific data to the sync servers?

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?
