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 usually save the information in my contacts address account. I don't want to keep a passkey, password, or pattern - all the time. I'm a senior and don't go out much except to grocery store 3 times a week or a doctor visit.

I am running into a strange issue with the Firefox app installed on my new mobile phone, and it occurs consistently while browsing almost all websites. The problem is that after a webpage loads completely, the right side gets slightly cut off. It doesn't seem to be caused by display scaling, font size, or screen zoom. Because if that were the case, pinching to zoom with two fingers should have brought the hidden right side into view. For example, on Reddit, when I try to check my profile or notifications, the right side gets cropped out. On the other hand, this Firefox support page is displaying properly, with no part cut off. I have attached screenshots of both. I am encountering this issue on several other websites as well. My device is a popular Samsung model. Other browsers, such as the pre-installed Google Chrome or MS Edge downloaded from the Google Play Store, do not have any such issue. So far, I tried removing all extensions from Firefox, but to no avail. I couldn't find anything relevant in the settings that could cause this either. I tried toggling the protection settings between Standard and Strict, but it made no difference. Is there any known fix for this issue?

I have both my PC and my phone signed into the same account and they are both synced. When using the option to send tab to my phone from my PC nothing appears on my phone but there's a pop-up on my PC saying it sent the tab or it was it's a check mark or something that suggests that it knows I wanted to send a tab. And then usually when I am trying to go to bed there is a tab that was playing on my PC so I go to bed and I open up my phone, I select the tab in the sync section and I sync the devices and then I attempt to close the tab. About half the time, honestly probably more the tab will not close and stays active on my PC and it is usually a twitch tab so then when I'm trying to sleep I just hear sound coming from my PC, the tab is gone from my phone so I can't even attempt to hit the x on it again so I end up having to get up and exit on my computer. I think also I've tried to send a tab from my phone to my PC, I could have sworn that was a thing and I don't remember that working either.

I was wondering if it's possible to lock a website's Login and Password Autofill behind a fingerprint prompt on mobile.

Sounds like a useful functionality, and would greatly improve overall App security, similar to how Samsung Pass works.

Thanks.

I am having trouble with the Firefox website YouTube.com, which has a notable bug where the YouTube video does not fill the screen properly as shown, and the Picture-in-Picture Mode is unable to show any videos properly in the small screen display. What can I do to manage this issue?
