Firefox for Android Community Forum

Hello, I have Firefox for Android 151.0.4 on a Samsung A50 with Android 9. On the SD card of the device I have several pdf files which can be opened with Adobe Acrobat with no problems. Instead, when I go to the device's file manager, move to that SD card, long-tap on one of those pdf files, tap on the three dots to see more options, choose "Open with" and finally select Firefox, I have that Firefox opens with a "File not found" page and the address bar shows, for instance "content://media/external/file/22098" while the pdf file I tried opening is "/SD Card/Test.pdf".

Is it possible to open local pdf files on my device with Firefox for Android? In the positive case, how can I do it in my case?

Thank you

I'm using Firefox for Android version 152.0.1 (Build #2016167575) on a Galaxy S24 Plus phone running Android 16.

Firefox is set as the default browser. It always opens whenever a task requires a browser. But when I try to open an HTML file by tapping or long pressing it, the dialog window that opens doesn't show Firefox as an option. Screenshot_#1_20260624.jpg

I have checked the settings in "Apps that can open links", all apps there show "In other app" In "Default apps", Firefox is under "Browser app". Screenshot_#2_20260624.jpg

What do I need to do so Firefox is either the default app for HTML files or at least shows up in the "Dialog window"? Screenshot_#1_20260624.jpg

Thank you!

Sometimes I am using the youtube app to watch something on a TV, but want to quickly look up a video for someone else on my browser at the same time. I have my settings to "always ask" me whether or not to open links in their native app or stay in FireFox. But recently the setting has not been sticking. I've had to reset the settings at least three times today. What's going on? Am I doing something wrong in settings?

Hello,

I've always used Firefox, and have had whichever Macbook and Android devices I've had synced for years. I recently got a newer phone, had an issue, returned it and got the same model. Since getting the new phone, Firefox not only takes hours to properly sync to be able to even see my Macbook's tabs, but I can't even send myself links from Macbook to my Android phone. Password and bookmark syncing is also spotty. I've tried signing out, made sure these are the only two devices on my account, and I've uninstalled and reinstalled. It's been this way through many updates for both my device and Firefox. I use both devices interchangeablely and it's critical enough to me that I may switch to a different browser. Any help would be appreciated.

For the past.. month I would say, any time I try to use Youtube on my Firefox Browser it nearly always switches over to landscape mode after watching a video. It doesn't matter whether my phone screen's auto rotate is on or off it still does it. Yes. I already tried to turn my auto rotate on to switch it back to potrait mode, it still won't work. The only solution I currently have is closing Youtube all together from my Browser, which really REALLY sucks!!

Can someone PLEASE look into the glitch?!

6/22から突然、文字入力ができなくなりました。 ・Gemini/OpenAI/ダックAIなど、文字入力が出て打つが入力されないパターンと文字入力すら表示されないパターンがあります。

・最初の検索バーで文字入力ができても、検索結果のページからは文字入力ができなくります。これも文字入力しても打ち込まれていないパターンと文字入力画面すら出ないパターンがありました。

When I click on links offered by the authors of YouTube channels, Firefox just refuses to resolve the links. I must open the link in another browser

0. Make sure Firefox is the default browser of your Android mobile phone. 1. Visit a YouTube video on YouTube.com 2. Click a link provided in the about-section for that video. 3. Link is sent to Firefox Expected outcome: that Ff opens the link Actual : it just stalls, probably due to a security measure taken by Firefox

Firefox keeps crashing. It was doing it even when I first got my phone, just not as much. I use Firefox on my laptop and like to be able to connect them both and the privacy or I would have gone to something else on the phone. Samsung A71 5g. I don't use 5g even thoygh the phone is capable of it. I don't trust 5g. I know the phone is old enough it doesn't get updates anymore, but I don't like the newer phones (no sd card being one of them).

i'm running firefox 152.0.1 on android 15 running on a samsung s23.

for some reason, firefox insists on downloading text files, instead of displaying them directly. in my experience, firefox used to display text files directly by default.

i checked this on a pc running firefox 115.26.0.esr and was surprised to see the same behaviour. in addition, although i'm able to specify display/download preferences in settings as usual, the option 'open in firefox' doesn't exist for text files...

can anyone tell me why??
