Video playback initially works, until suddenly it doesn't; no new videos will work, and videos that previously played in the same browsing session will stop working. Easy to reproduce on Reddit by browsing any video-heavy subreddit. Leaving a broken video in a tab seems to infect the rest of the browser across websites; if a broken video from site A is open in another tab, videos on site B won't play.

Sometimes quitting and restarting Firefox is enough to temporarily get video playback working again; sometimes I have to manually clear the browser cache; at least once I've had to reboot my phone.

Firefox is using a large amount of battery while idle. You can see my app runs open a lot of the day, but not in use much. It has drained 20 percent of one days battery, and I am watching YouTube videos on another app (Grayjay btw check it out!) and it has used far less battery. If I set Firefox into a sleeping state, the app still drains a lot of battery. When in deep sleep,it stops draining as much power, but then Android keeps auto pushing their own browser to be my primary browser. I'm not sure what to do in this case, as it's too much of a hassle to have links not auto open in Firefox when in deep sleep. This excessive battery drain doesn't make sense, and I was wondering if there was any fix for this. Thanks for taking the time.

The browser itself works in 120 Hz, but if you open any page, the phone switches to 60 hz. However, if you open, for example, the keyboard, 120 Hz is enabled again. This makes using Firefox uncomfortable. I have attached screenshots that show my problem.

When I try to enter a password for any website after a few updates ago, I don't get the option to enter my password that's saved in my password list into the fields anymore. I have to manually search, copy, and paste the information in. The app will then ask me if I want to update or modify the login information that is unchanged from what should already be in my browser.

Regardless of whether I say yes or no, the password remains unselectable when I go back to that website, and when I manually enter the information, it again asks me if I want to update the login information.

This hang is not consistent. I have been switching back and forth to get details for this thread with no issue. But very frequently when I have switched away from Firefox to another app and then returned to Firefox the app has completely frozen. I can see everything clearly but can do nothing at all (neither the web page or Firefox). I haven't yet identified a pattern.

132.0.2 has Relay and CashRewards installed. 133.0b8 is vanilla.

I'm using gesture controls on HyperOS to switch apps.

No issues with any other apps.

Is this where I report such things?

Video of the issue

If i open a link to redirect to an app, let’s say wikipedia, it will redirect fine. When i switch back to Firefox, the mobile version of the link i clicked on will be loaded instead of just displaying search engine search results where i clicked the wikipedia link. (Admin note: edited to fix formatting issue)

Another thing that happens is if i click on the link, still being wikipedia, get redirected to the app, then close out firefox, the next time i open firefox, it will redirect me back to the wikipedia app.

This issue I have been having is not just related to Wikipedia, this is for any other link that may open a related app I have installed on my phone.

I recently downloaded Firefox on my Android device. It's been fine. However today, there was an issue. I have the settings set on my phone so bookmarks appear on the homepage. However, today, for some reason, the bookmark on the homepage was glitched. I'm not sure why, but I figured I just had to reset it. So I go rid of the bookmark on the homepage, and redid the bookmark. It was working again, but now, the bookmark isn't appearing on the homepage anymore. It's just a blank homepage, even though my settings are still the same. I've turned the settings on and off, reset fire fox, cleared cache, and the bookmark still isn't showing up. Pleas help me.

The upload photo button does nothing... on this page, on Reddit, Facebook too. I've tried clearing cache. I'm on latest android and firefox 124.2.0. I have standard security enabled and permission is set to "Ask" for camera and storage. How do I make this work again?

This bug appears to have happened before: https://github.com/mozilla-mobile/firefox-ios/issues/15525

A white toolbar appears at the bottom of the screen (when using a Bluetooth keyboard) or above the floating keyboard (if using the iPad on-screen keyboard). It takes up space but serves no function and often makes it difficult to view whatever webpage I’m looking at, or, even worse, to see what I’m typing if the input field is at the bottom of the screen.

If the “Done” button is clicked, the bar goes away, but then doing so also exits the input field, so I can’t type any further if I close this toolbar. The up/down arrows seem to serve no function.

I have tried uninstalling and reinstalling the Firefox app but the issue did not go away.

This does not happen in any other app, including other web browsers like Safari.

Any advice, or a bug fix, would be much appreciated.

I am migrating to a new phone. WhatsApp offered firefox as an option for storing its passkey. That took me to the connection and synchronisation process which the new phone said had failed. However all my tabs and other passwords appear to be syncing. Now selecting firefox to store the WhatsApp passkey takes me back to the failure page every time. Any idea how to restart the passkey addition to firefox process? WhatsApp won't work whilst I'm hung up in limbo between the two apps.

I am using Samsung S23 with the latest One UI and Android 14. Samsung's built-in browser has a neat feature where you can open YouTube or Reddit links in the apps installed on the device instead of viewing them in the mobile version of the website in the browser. I assume that Firefox has the same functionality called "Open links in apps" in the settings, but I tried all the available options and neither YouTube or Reddit links are automatically opened in their respective apps, nor is there a button anywhere to force them to open in the apps. Am I doing or assuming something wrong, or is this a bug?

Hi on my ipad 10 ios 16.1.1 with firefox 129.2 (44469) I am "paired" or logged in as my username BUT i simply cannot autofill passwords - even though the box "use saved password" appears on sites ive registed....

I then tried logging out and in again and repairing the device and - same deal.

Also, when i goto "settings > passwords" it says:

"to save and automatically fill passwords, enable face id, touch id or a device passcode.....learn more" That support article does not seem to solve anything for me.

I am using firefox on my desktop and my iphone and both of those work.

Hi, Most of the time when I search, the engine automatically used is Bing and not Google. This is despite setting Google as default.

Is this an annoying bug? Or am I doing something wrong?

Thanks

Hello,

Why some websites aren't working properly with Firefox but does with others?

Here are two websites that I have issues with:

https://bell.ca (Home internet section, can't scroll) https://cogeco.ca (Business internet section, can't scroll)

For the past few months, videos on YouTube haven't been playing properly. They load just fine and there's no issues with the auto, but once the video starts playing it will sometimes be zoomed into the top left corner, making it impossible to properly see what's going on.

This happens with music videos too, both official and lyrical. It will be zoomed in close to the top left corner and just barely catches what's going on in the video. Sometimes, video do play like they're supposed to, but for the most part, they'll be zoomed in as soon as I hit play.

as described, send tab function does not work one way (android to PC), but works fine from PC to android mobile phone/tablet. the pop-up error is the "Unable to send - RETRY", and pressing 'RETRY' doesn't do anything. I am logged in to the mozilla account on both android devices, and firefox sync/syncing tabs work fine. not sure what's the issue
