  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.

Device: Motorola Edge 30 Neo with stock Android 14.

I am using Fennec: 124.1.0 (Build #1241020), 516df33ca9+ GV: 124.0.1-20240326023132 AS: 124.0

I'm having the same issue as previously posted below. I am on a Google pixel 7 pro.

"On youtube mobile site or a reddit video, when I click the bottom right button to fullscreen the video, a message pops up that says 'entering fullscreen mode' (with a firefox logo on the left of the message) and then firefox closes and I'm at my android home page

This seems to happen when I watch videos in a new instance. If I reopen firefox to the video and then try fullscreen again, it goes full screen no problem. So basically it's annoying and happens when I try to watch any video full screen for the first time.

Is this a known bug? Wasn't an issue on my old phone (I just got the galaxy s23). "

I just did a Google image search on my pixel 8 and saw that all the image results were forced to "fit width" so I can only really see 1 result at a time. I have the "Google Search Fixer" installed and dialsabling it returns the image search view to gallery. But when I enable to addon it goes back to that "ft to wish" view.

I've looked through the options and tried searching for similar problems/solutions and found nothing. How do I return my Google image search view to gallery? It's really obnoxious and frustration to only be able to see 1 image at a time when searching.

When playing a video on YouTube the video is choppy and drops around 2/3 of the frames. This happens on every video that I click on.

I have found that if I double tap to jump back 10 seconds in the video it will no longer drop frames and play smoothly, but if I change the playback resolution it returns to being choppy until jumping in the video again.

I am currently running the latest stable download from the play store, and my phone is a OnePlus 8t.

Hello, everyone!

I'm encountering a perplexing problem with downloading .mobileconfig WiFi profile files through a direct link in my ReactJS web application. This functionality works flawlessly on Google Chrome, Safari, and Edge across iPhone and iPad devices. However, when attempting the same on Firefox for iOS, the downloaded file becomes corrupted and unrecognizable as a .mobileconfig file.

The download mechanism is implemented using a simple anchor tag that points directly to the file on the server. Interestingly, only in Firefox on iOS, the content of the .mobileconfig file gets altered during the download process, leading to corruption.

I'm keen to understand why this issue is occurring specifically with Firefox on iOS and how to resolve it. Has anyone else faced a similar challenge or have any insights on how to ensure the file downloads correctly on all browsers, including Firefox on iOS? Any advice or suggestions would be greatly appreciated!

Thank you in advance for your help!

Whenever the app leaves the foreground, even for half a second, or if I switch tabs and then return to the original tab, it refreshes and I lose all the data on it. When I need to copy information to fill out a form, or get a code from a 2fa app, I lose all the the progress. This is driving me crazy and making it almost impossible for me to use Firefox as my main browser. I shouldn't have to restart a whole form because I got a phone call and went to the call screen for a second. Battery optimizations are all disabled.

It's so annoying that you ask for my password when I'm already logged in obviously. I'm on the same phone the same internet at the same address you should know by now it's me. And then nobody remembers the password even though they said they remembered it and I don't remember it. And it says if I reset my password I'm going to lose all the bookmarks and all of my logins. What the heck? Why isn't there always option just to login with my Google account? It does sometimes but not always.

For some reason my browser occasionally jumps over to a private browsing tab and I may never realize Firefox has performed this action. I may continue with my research for any length of time when I may need to look at something other than my browser, say jump over to a Note or some other function not having to do with Firefox, when I return I find maybe an hour of research has automatically been closed and of course there is no record of that lost work. This function is really frustrating additionally it's tricky that a link to another site or page of information can cause the Firefox Browser to open the following tab in Private Mode, then automatically close when it becomes necessary to look at some other functions on my Android device, everything is wiped out gone lost no way to retrieve the info.

What ever happened to Lazarus, the app that always brought back lost work, private or otherwise? That was an excellent and very helpful tool. Is there some other way unknown to me where I can retrieve those closed private tabs, how do I stop the links from auto-opening privately, and I'd like to know how to stop private tabs from closing when I leave those tabs to focus on something other for a split second.

Please advise. Thank you.
