Hi, I have a Xiaomi Rednote 10 pro mobile phone. I have been a longstanding user of Firefox on numerous devices.

However I am having real difficulties on my phone when switching away from the app and returning (for example to check a code for MFA). I have checked battery settings (unrestricted), background autostart (enabled). I've tried locking the app in the recent processes list, in developer settings "don't keep activities" is off and background processes is set to standard limit.

Even with only 1 other app in memory every time I activate another app and return the page reloads and I lose what I was doing.

I've tried uninstalling and reinstalling and have the most recent update.

Other browsers on my phone such as Chrome do not exhibit this behaviour - when I switch apps and back again the page in the browser is retained.

Is this a known fault with this type of phone? Am I doing something obviously wrong? Any help you can provide would be greatly appreciated.

There's an issue with Android Firefox where a tab sometimes just suddenly freezes and there's nothing I can do to unfreeze it. I cleared cache, restarted the app, refreshes the page and nothing works. The only thing I can do is to copy the link, close the tab, and open the link on a new tab.

I have Firefox 152.3 (73911) on iPhone with the latest iOS 26.5.2 On Firefox, web pages not showing up when switched between open apps on iPhone.

I can see web pages on Safari.

fonts.googleapis.com is locking up websites for 40 to 60 seconds per keystroke. I have researched this problem and tried everything suggested, but nothing works. Much of the solutions include changing the settings used on menus which no longer exist. accounts.google.com is doing the same thing. This is driving me nuts. Help!!! Latest version of Firefox. Windows 11 desktop computer.

Since updating to 152.0.4 on 30 June firefox has frozen multi times a day, nothing is responsive. I've had to force close and restart. I performed suggest hang fixes, refresh, changes places names, turned off accelerations. None of that resolved the issue. I did not have this issue prior to 152.0.4. No crashes, just hangs forcing restarts - but each one forces me to re-enter all my user information for the various sites I'm using. I've see some references of similar issues with others having upgrading to 152.0.4, but there don't appear to be any clear fixes. Is this issue being evaluated?

First, I press fullscreen mode on any video on the firefox browser. Second, when I enter fullscreen mode the pop-up that notiifes me that I entered fullscreen mode appears but it takes multiple minutes to disappear.

While I was using Firefox, the inspector console window started opening and closing all of a sudden. Whenever I try to click on a different tab that is not the one I am currently on, it switches back to my current tab. This issue also occurs on other Firefox-based browsers, and not on any other browser I have installed.

I attempted to change the theme, I went into Safe/Troubleshoot Mode, disabling my extensions, etc, but nothing changed. I've restarted my computer twice already, and yet it doesn't seem to change anything.

The only way I could temporarily halt it was through holding Ctrl, Alt and Shift at the same time, but this only worked for as long as I held all three keys down. What should I do about this?

Hello Im using multiple firefox edition on my PC from beta dev to nightly, and recently in nightly and only nightly I've spotted strange issue that appears as window in window screenshot attached, outer x to close or maximize window does not work only the inner and mostly goes after F11 full screen and then return to normal. Troubleshoot mode and restart does not change or fix this.

For the last 2-3 weeks, the browser has been freezing when opening new tabs. This doesn't happen all the time, but the same tabs can open correctly or the browser stops working when they are opened. The work stops for 10-20 seconds. The browser does not respond to clicks, but if you press the Win key, the window turns bright and "not responding" appears on top of the frame. I was trying to solve this problem on my own. I ran it in safe mode, disabled hardware acceleration, updated drivers for the integrated graphics and discrete graphics card, disabled all extensions, created a new profile, reinstalled the browser completely - none of this helped, the browser still freezes when opening new tabs. I also cleaned the download history, changed the proxy settings, and disabled Windows Defender. What else can I try to do to fix the browser?

When I leave FF and open it again after some time I would get a black screen and the app would not show the content on the current page or query a new search for several seconds which gets annoying when doing multitasking

I have a poco X7 pro if that matters

Hardware acceleration is turned off. Firefox does not show the GPU usage in task manager (which is very worrisome in its own right) but when watching a single stream twitch.tv my GPU usage is 60%~100% (which only shows on the GPU tab of task manage). If I close firefox, the usage returns to 0%. The usage also becomes 0% when the stream is not the active tab.

I believe this is a recent behavior change as I noticed it due to it causing games to have low FPS. The excessive usage is also present with only firefox running.

This is happening on a 7800x3d, RX 7900 XT and 32GB of ram.

I also tested on youtube and found it to be using 10% less gpu on average but after while it settles down to ~30% usage.

If I enable hardware acceleration, Firefox uses the iGPU at ~50% usage and still uses 50%~60% of the dGPU. Performance of videos doesn't seem to change whether hardware acceleration is on or off (where as on chrome there is a very noticeable difference).

Used Chrome for sanity checks and it does not affect games FPS while using on average half the GPU usage of Firefox. Chrome also reports it usage in task manager correctly.

I suspect Firefox may be calling GPU encoder\decode hardware incorrectly and always using hardware encoders\decoders regardless of the hardware acceleration setting.

For some reason, opening the tab list on Firefox and Firefox Beta on Android takes 4+ seconds and it's very annoying.

This is on a completely fresh install of Firefox with literally no changes or tabs. It doesn't matter how many tabs I have. It takes about the same amount of time with 0 tabs or 100. This didn't use to happen with Firefox versions from over a year ago. There's something about the new method that caused this for me.

I'm on Android 10 on a Galaxy Note 9. Nothing else (meaningful) running in the background or anything.
