Firefox for Android Community Forum

I hope to add the feature of opening local HTML files to Firefox Android version. Firefox used to support this feature in the past, but it was removed after the release of Firefox Daylight, which was restructured. Firefox supports opening PDF files, but it does not support opening HTML files, although opening HTML files is closer to the browser's function than opening PDF files.

On the latest Firefox Nightly builds (I use Nightly for extensions), holding the back button in the Android navigation bar no longer brings up previous pages, like it does when holding the back button in the three dot menu. Is there a config option to bring this back?

Prior to the 6/16/25 release, hitting the back button on the three button control on a page with no previous pages would open the home page without closing the current tab. After the update, it closes the tab before opening the home page. This was useful for quickly opening multiple tabs, as well as preventing accidentaly closing a tab. Please revert this change, or make it a setting.

This hang is not consistent. I have been switching back and forth to get details for this thread with no issue. But very frequently when I have switched away from Firefox to another app and then returned to Firefox the app has completely frozen. I can see everything clearly but can do nothing at all (neither the web page or Firefox). I haven't yet identified a pattern.

132.0.2 has Relay and CashRewards installed. 133.0b8 is vanilla.

I'm using gesture controls on HyperOS to switch apps.

No issues with any other apps.

Is this where I report such things?

I want Mozilla Firefox as a default search engine in my Firefox browser. But I am unable to do so. There is no option to make it as default search engine in the app. Please help me as soon as possible.

There used to be a forward arrow option in the three button menu. Now there is not and I cannot find out where it is or how to navigate forward.

This seems like a bug because navigating forward is a core function of browsing. Anyone know where it went or how to fix this?

I am having a downloading problem in Firefox Android browser. I cannot download from any site. There is no problem in Windows version but there is a downloading problem in Android version.

Why oh why doesn't the mighty Mozilla allow me to organise my bookmarks alphabeticaly. Much lesser browsers do, Mozilla doesn't allow me to organise bookmarks at all. I use bookmarks extesively, it wouldn't take much coding to allow me to sort them. Putting them in as saved order makes no sense. Come on guys 'n' gals get with the program!

I own a Samsung Fold 5 phone. I have set the outer display used when the phone is folded to 300dp. The inner unfolded width is set to 601dp.

Up until very recently, when I folded or unfolded my phone, websites would resize. Often switching between layouts made for phones and layouts made for tablets or desktops. This still happens in Chrome. But no longer does in Firefox. Instead the site has the same resolution in both modes, making the text too small to read when folded. This effectively makes Firefox unusable unless I unfold my phone. Please make Firefox respect the resolution I have set for each mode again so I can view websites at a width of 300px in folded mode like I used to.

Note I have the slider for "desktop site" turned off. When I try to turn it on, nothing happens. The slider doesn't activate and the resolution does not change. (But the page does reload.) This used to give me the option of 3 different resolutions for my screen, (300 folded, 601 unfolded, and something like 1024 in desktop mode.) I'm not sure if desktop mode is permanently turned on now, or if the phone is set to permanently use 601 width, but it is definitely not using the 300 width I used to get when folded. The desktop mode slider is to the left and will not change.

I opened site settings and turned off always request desktop site and nohing changed. I am still unable to get the 300 width site I need to be able to use Firefox on a folded phone.

The ' add home screen ' function not working. If i click on it than the the function is not working. It is not adding the webpage to home screen. Or sometimes this function is very useful to install the webpage in our mobile but its not working. Please fix this.

Firefox browser for Android is my favorite, but it still has many shortcomings, like you cannot use private DNS in it, there is no option of bookmark import export, you cannot move bookmarks up and down and create a group of tabs and you cannot use themes, and there is no Hindi language in the inbuilt translate, and the speed of the browser is also low and not smooth, I request you to work on whatever I have told you and implement it in the browser, thanks
