Firefox for Android Support Forum

I have the latest version of Android 13 and Firefox up to date on my phone, but there's been some weird behavior when playing videos as of late. Videos refuse to properly go fullscreen now. When I tap the fullscreen button, the video moves to the center of the screen but stays in portrait orientation, which is obviously not what I want. In addition, picture-in-picture is not working at all, and the notification control panel (that lets you pause and play minimized videos from the notification) is not appearing even though notifications are not disabled for Firefox. Videos still play, but almost none of the features for them are working. What is going on? Can anyone help?

Dear Firefox Support Team,

I am writing to seek assistance with a technical issue I've encountered while implementing a backdrop filter and animation on a navigation bar.

To provide some context, I have incorporated a backdrop filter effect on our navigation bar, accompanied by a translateX animation to reposition it smoothly. However, when testing the website in Firefox, I have noticed a noticeable choppiness in the animation performance. This issue persists on both desktop and Android devices.

To help you better understand the problem, I have included a screenshot, so you can see the issue.

I would greatly appreciate any guidance or suggestions you may have on how to address this problem and improve the performance of the backdrop filter and animation in Firefox.

For your convenience, here are the relevant links:

Your expertise and support in resolving this matter would be invaluable to our project. Thank you in advance for your time and assistance.

Sincerely, Aram

I own a Samsung Galaxy Tab A8 and Samsung Galaxy A42 5G. Neither of these devices has the monospace font Courier New installed. However, when using Chrome, text boxes on websites that use Courier New are displayed in a different monospace font (which I've been unable to identify). On Firefox, they are not. This breaks the appearance of some websites which rely on text being monospaced but don't include "monospace" in their CSS font family.

Image 1: Screenshot of a website that uses Courier New, as it appears on desktop (both Firefox and Chrome). Image 2: A snippet of the CSS used in that website, showing that the font family is "courier new,courier" and does not include "monospace". Image 3: The same website using Chrome on mobile (on both the phone and the tablet). The font is distinctly not Courier New (or Courier), but is still monospaced, salvaging at least that aspect of the text. Image 4: The same website using Firefox on mobile (on both the phone and the tablet). This displays a non-monospaced font.

The obvious fix is to simply install Courier New on the phone and tablet, which I'm working on doing (update: this is much harder than it should be). However, I think Chrome displaying a different monospaced font when the requested monospaced font is unavailable is a good user experience feature, and would like to see it mirrored in Firefox.

Hello Mozilla team.

I need your help with the following: I recently upgraded my device and I got Samsung S24+. Unfortunately Mozilla is not working properly. Whenever I open a new tab or open a link via my email account it is flashing constantly without being able to browse as usual.

Any help? (I have already unistalled / reinstalled the app.

Look forward to hearing from you

Kind regards

HELP! My mobile data usage spiked as of June 20th and has continued at unprecedented levels almost every day since. My historic daily usage for the past many years has been around 4 MB and is now 95MB. and busting through my 2GB/month limit. This is ALL due to Firefox! What happened? Something strange happened on June 19th, when my mobile date usage recorded three separate usage figures instead of the single usage figure for all days previously. June 19th showed 2 usage figures and June 30th showed 3.
