When I try to go the the site https://tvlistings.zap2it.com/ it show top part of page while it tries to retrieve TV listings, but then the whole page goes blank. It still goes blank when in troubleshooting mode.

Works with Microsoft Edge browser. Any ideas?

Hello Please explain to me how to transfer tabs from desktop to Android phone because there is no option on my desktop browser settings and no matter how much I sync, the desktop tabs will not be transferred to the phone again. please guide me

I broke an old computer and have my logins from it on a backup drive in logins.json and key4.db. I can't work out how to transfer these logins to my new computer. I've tried creating a new firefox profile since I am nervous of losing logins that are on my new computer, but then I am totally lost.

Audio was working fine until recently. Now, firefox has no audio playing on any site.

Some sites show "PLAYING" in tab, but others like YouTube don't show that notification. Even with "PLAYING", there is no audio output.

I checked Windows settings and Firefox is set up correct (and the same as it was before it stopped working), see screenshot attached. Otherwise, I restarted Firefox, tried it in troubleshoot mode, and reinstalled Firefox. No changes.

Possible system changes include: Maybe a Firefox update occured and broke the program? I installed the game Civ5 from Steam which required some Windows VS redistributibles installed.

Hi! There are multiple recent threads on this issue, and not one of them has a solution, so I'm asking again. I want to increase the font size of the top header text, specifically the bookmarks toolbar, search bar, and tab titles. The text is too small for me to read. It would also be useful if I could increase the font size for the applications menu (the hamburger drop down menu in the far right of the header).

I do not want to increase the size of anything else, so changing layout.css.devPixelsPerPx is not the solution. I have changed my global zoom settings, and set them specifically to "Zoom text only", but this setting does not effect the bookmarks toolbar or the search bar. Changing the default font size also does not increase the size of this text.

Just to clarify again, these threads are not solutions to my question: https://support.mozilla.org/en-US/questions/1214027 https://support.mozilla.org/en-US/questions/1293358

I have an extension (completely blank) that can't be deinstalled. I am trying to use the "refresh firefox feature" to get rid of it, but the button simply isn't where it should be. The text is german, but none if these Buttons are the one I seek.

Why are google sites (Youtube, Gmail and Search) getting disconnected when all other sites are still connected to the Net? This has been happening since November 2021.

When that happens I close the FF and then immediately open it. Now the google sites work properly.

Never had that problem with other sites.....never!

Why the hell is this happening? Is FF responsible or Google?

So what is the solution?

This question has to do with logging into web sites with an email and a password. Firefox 101.0.1 (64-bit). Windows 10.

On many sites, when I click in the email field, a drop down list of email addresses appears from which I can make a selection using the mouse or up/down arrow keys. Some web sites have as few as two email addresses in the drop down list, others have many more. I recall that one site has about fifteen email addresses in the drop down list.

How can I remove a non-applicable email address from the drop down list?

How can I clear the drop down list of all email addresses?

Thanks.

Firefox allow to disable access to canvas for lowering fingerprinting, it's cool !

But as web developer : i like to ask this access before try to using it,

Something like :

1. Do you alllow canvas ? 2. Show the browser part 3. Wait for user answer 4. It's OK : download PDF done with canvass 5. It's not OK : shown an error to user.

To avoid such situation (see screencast)

For some reason, whenever I load a pdf from within Firefox, I get a new tab with the regular toolbar displayed on top of pdf files, but the document itself is completely blank (see attached screenshot). This issue just started today and I assume it was a result of an update, since I don't recall making any changes to my settings (I'm using Firefox 101.0.1 on Ubuntu 20.04).

I've tried opening multiple files from a variety of sites with the same result. All of them open fine using my system's pdf viewer, as well as from within Chromium. I've tried disabling my plugins, putting Firefox into safe mode and resetting all the handlers, to no avail. Any help would be much appreciated.

Please see https://support.mozilla.org/en-US/questions/1311330 That solution does not work for me. Mac Pro with M1 chip running 12.4 Thanks!

I used a siteblocker and i tried blocking about:addons, wouldn't allow it so someone tell me how. im literally trying to prevent myself from removing extension i literally jumped from one browser to another just to make this shit possible please.

Hello, I've used AddBlock successfully for years but now , to my utter dismay, It has stopped functioning. I tried unsuccessfully to reset Firefox . Have just gone through the latest StartPage privacy protocol added to Firefox, but I am still beset with beastly adds. Hope you can help, Cordially, Joy

Hello,

Since 2 days ago, I've been unable to stream Amazon prime videos via Firefox. I'd get the error "Video unavailable. For assistance, please go to amazon help".

Amazon prime videos stream fine in Chrome Amazon prime app on my Android phone also works fine.

I have tried everything on the amazon help page (unless they don't apply), still won't work.

(List of their tips:

   * Close the Prime Video app on your device (or your web browser, if you're watching on your computer).
   * Restart your computer or connected device.
   * Ensure that your device or web browser has the latest updates.
   * Ensure that you’re not using the same account on multiple devices - you can only stream the same title to two devices at a time.
   * Ensure that any external device is connected to your TV or display using an HDMI cable that is compatible with HDCP 1.4 (for HD content) or HDCP 2.2 (for UHD and/or HDR content).
   * Pause other Internet activity – especially if other devices are using the network at the same time.
   * Check your Internet connection. You may need to restart your connected device and/or router.
   * If you’re able to connect to the Internet on other devices, update your connect device’s DNS settings. Please check with your device’s manufacturer for further details.
   * If you’re attempting to control a device using Alexa, try to unpair then pair the device again in the Alexa app.
   * Deactivate any VPN or proxy servers. )

Similar issue with Audible. Cannot play anything via Firefox. It's just frozen. Audible app on my phone works fine.

Thanks for your time
