1. Sometimes I use the browser while the system is in dark mode.
2. Then I switch system to light mode. FF recognizes it and switches to light mode accordingly.
3. Then I use it in light mode for a little more.
4. Then some time passes (maybe a few hours), I don't use FF during that time.
5. Then, I tap on FF icon, the browser starts, but immediately switches back to dark mode, while the system is still in light mode.
6. I have to close FF by swiping on it in task switcher, and then tap on the app again.
7. FF now uses light/dark theme according to system.

Every time I'm trying to stream video like live sports the video lags so much. I've tried to reinstall the app and run it with no addon ( even though I only use 2 addons) and problem still persists... I'm using a Samsung S21 Ultra.

When displaying an iframe video in a popup, clicking the close button and other click events do not work. This issue only occurs in the Firefox browser on Android, while it functions correctly in the Firefox browser on iOS.

Is this a default behavior.

I want to update to the latest version but the "Text selection magnifier" is stopping me from updating firefox android. Because I find it pretty useless and very distracting when viewing text while selecting the text in a website/article. Please provide a toggle for it in the Settings.

When commenting on 9gag, the blue "post" button disappears. If I choose "Desktop sight", the entire page reformats and becomes different and I lose all of my posting information.

My computer restated itself with an update. Now Firefox and all my bookmarks and saved log in info is gone. I normally can solve this by simply logging in and syncing from my phone. Firefox will not open a log in page from any of the icons on any Firefox page. I can log in using Chrome but of course sync from there is not possible. I can log in on my phone also. The problem is either my Mac settings or the Firefox settings on that computer. I have searched FAQ etc. No clear solutions can be found.

I have Firefox on my Windows 11 desktop computer. As of today, I cannot see my Firefox on my Android smartphone. The problem started when I saw that my computer desktop Firefox would not automatically update. When I tried to update manually, I lost my ability to use my Android Firefox. Don't know what to do next.

I use the mobile version of Mozilla firefox and it choose to "remove" the open in other app feature for certain apps.

If I open youtube.com mozilla would ask to "open in other app" as an option instead of just opening it in the browser, youtube, twitter/X, reddit, etc. are fine, but for certain apps such as Pixiv and Patreon the option just dissapeared entirely, not even in the tripple dots at the bottom right does this option appear, can anyone help?

Any website that uses OscillatorNode and other similar features has the audio generated devolve into a crackly mess after only a second or two.

Whenever I use Firefox the UI image elements will become oversized making everything squished. I have provided pictures of the incorrect display and what it looks like on my default browser fir reference.

On the Firefox Android app, after closing few tabs, exiting the application and re-entering the application, the closed tabs reappears as if they weren't closed at all. I found this is a well known bug and there are few open threads on bugzilla on this topic. Someone said that's related to a corruption of the closed tabs' json file.

PS. It's difficult to share a screenshot, probably a video is more explanatory

When i try and accept an e-transfer using Firefox, I'm getting an error message "Application error: a client-side exception has occurred (see the browser console for more information". I've always been able to accept e-tranfers in the past.

Hi I've been having an issue with adding bookmarks lately. I have a lot of Bookmarks as such I use a lot of bookmark folders, often multiple folders within one another.

The issue I have is that when I add a new bookmark on mobile Firefox displays all Bookmark folders all at once leading to a lot of scrolling in order to get to a specific folder. This can lead me to several minutes of searching as I try to find a specific folder.

This could be solved by implementing a drop down box to hide folders within folders.

Anyhelp is appreciated.
