I can't enable USB Devices on about:debugging setup page. I already installed ADB toolkit for MacOS, also I can see my device in ADB devices list: ``` ~% adb devices -l List of devices attached 013db356 device usb:336723968X product:OnePlus6T model:ONEPLUS_A6010 device:OnePlus6T transport_id:9 ```

On the device I've enabled "Remote debugging via USB". But when I click on "Enable USB Devices" button, nothing happens. I can see only "Updating..." message, then "Disabled" again.

Also no devices in the devices list, because USB Devices are disabled. "Refresh devices" does not make any changes.

Hi, I need to update my credit card details for my monthly donation to Mozilla but I cn't find out how to do it. I can't find a way from my Firefox user account to do it. Clicking on the only link I can find to Donate just throws a 403 error. Clicking on a link to help for Mozilla Donate does the same thing. Please email me advise how I can do this. Thanks, Andrew

I use Yahoo mail from my Firefox browser (mail.yahoo.com). Today Firefox won't let me begin a new email. I click the "compose" button, which should open a new blank email, but nothing happens. I tried in Safari and I can do it there. Please advise and thanks for your help.

Having a hard time trying to figure out why Firefox View would be completely empty every time I check it (see attached image). I use Firefox all day long on my desktop and phone. My account is synced on both. Is there a settings I'm not aware of?

Thanks for help.

Every time I launch Firefox a message appears on the top right corner asking to update with the following text: "Update available Download the latest version of Firefox"

I have never followed this message for I've suspected fake, but it keeps appearing, and every time more and more often along the day (at the beginning it was only once per launch). This keeps occurring in spite of updating to the latest Firefox update (103.0.2) through the "About Firefox" top left menu on my Mac.

Please advise how to get rid of this annoying message. Is this a potential hack or virus attack?

I keep trying to add Honey extension using Firefox. It shows that I have downloaded the extension, but it is not working. I know I am doing something wrong, but I don't know what it is. Thank you!

I attempted to install a router but Mozilla sent a caution message that the brand (Net Gear) was insecure. Which brands are secure routers?>I have a Mac Book Air purchased a few months ago and have never had internet at home. This is first attempt. Thanks.

Hello,

On MacOS 14.0(Sonoma) Firefox 118.0.2 (64-bit), facing the problem with web.whatsapp.com chat messages. The timestamps for the messages are displayed in UTC and not as per the system time(IST, in my case).

- web telegram shows correct timestamps, opened in same browser session - web whatsapp on Chrome shows correct timestamps - fingerprinting is set to false(was not touched at all).

Any idea what could be wrong? Thanks. -Sachin

When I watch fullscreen videos in another browser (Chrome, Safari, etc.) on my Mac the video fills the entire screen. For some reason when doing the same in firefox the video does not reach to fill the entire screen and instead only occupies the middle. I tried screenshotting to illustrate this behavior but the screenshot was restricted to this middle zone as well. It seems like somehow firefox is shrinking the display size when no other browser exhibits the same behavior.

It also seems like if I want I can drag the video window around in fullscreen moving the whole video player around my display. I shouldn't have to drag the thing around to get the video to play right.

My bank has recently switched the position of 'online' and 'bank name' in its login URL. How can I delete all history for the old URLs (e.g. Bankname*) without deleting history for all non-bank-related URLs?

This blue icon recently appeared in the upper left corner, and it's there even when I watch video full screen. Clicking on it doesn't do anything. What is it and how do I get rid of it when I want to watch video?

Recently, when I try to play a video on YouTube on Firefox, there is a flickering brightness effect (some aspects of the video seem to flicker bright and dark quickly) which is distracting and makes it difficult to watch anything. The effect persists even when launching in troubleshooting mode, and disabling hardware acceleration and restarting appears to have no effect. I have also been unsuccessful refreshing Firefox. Nevertheless, this issue is absent on Safari and Chrome when watching the same video.

Watching a solid colored video like this helps see the issue best, if it is happening to your device: https://www.youtube.com/watch?v=hJmFYZEcpZA The brightness switch is visible even when pausing the video.

When I find the same video two different places (ex: the Apple Sept 12 Event on Apple's site, versus on YouTube) only the YouTube video has the issue. However, I can't find any settings to change on YouTube to help this.

Hi all. I've been using Firefox for years on my Mac. It's my browser of choice.

A couple of days ago, my Mac installed an OS update (v13.5.2). After the reboot, I opened Firefox and discovered that it, too, had installed an update (v117.0). But when I got into Gmail and tried to turn on desktop notifications, it said this:

Note: Notifications have been disabled in this browser.

And it's right--no other sites are sending me their usual notifications, either.

My problem is, I can't figure out why notifications are disabled in Firefox suddenly. I didn't disable them. I've tried clicking the lock on gmail's site and setting its permissions to allow notifications, but they aren't coming. I've checked my Mac's preferences, and Firefox has notifications enabled there, as usual. Gmail works fine on Chrome--notifications are working. I've tried reinstalling Firefox--no change. I've tried running Firefox in troubleshooting mode--no joy. Other sites aren't even asking for permission to send notifications. Like Gmail, they appear to believe notifications are disabled in the browser.

I've searched the web for solutions, but I can't find one that tells me where the enable/disable switch is. Can some kind soul please help me out here?

Thank you SO MUCH in advance!!

When I click on a link from an email or document, Firefox opens but goes to my homepage and doesn't go to the link page. I've tried setting my home page to blank, changed the settings for opening a new tab or window, and the one for "switch to it immediately" but it doesn't seem to help. How do I fix this? Thanks, A PS I'm on Mac OS 10.15.7 Catalina with Firefox 117.0
