Whenever I use Firefox 109.0 (on Ubuntu 22.04) to transfer money between savings and checking in my online banking account, I get a window pop-up that says "No Apps Available". This is something going on my bank's servers and shouldn't require Firefox or any local helper apps on my end to do anything. I will post the window that pops up. Has anyone else encountered this? And is there a way to disable these pop-up?

When clicking on a link to an .mp4 file, Firefox navigates to a builtin video player, streaming the remote video file. When Firefox is unable to stream or display a file (as is the case with .mkv or .txt for example), it is downloaded instead.

I simply want .mp4 files to be downloaded when I navigate to them. I tried setting `media.mp4.enabled` to `false`, and that worked, but it also disabled most embedded media players.

All of a sudden when I press F6, it starts a Google search (see image) instead of just focusing the address bar. This is rather annoying because I use F6 all the time to go to a different page (e.g. type "mail" and then follow the autocomplete to mail.google.com) and that doesn't work if it wants search google for mail instead.

How do I revert this to its normal behaviour?

I'm trying to login to my Firefox sync account, and when I login with email or qr code I get stuck with the screen saying warning. Soon after I left my phone to login and came back 15 minuets, and it continued "working".

The free version allows for 5 masks. Is that 5 lifetime masks or 5 active masks? Example: If I set up 2 masks I have 3 remaining. If I delete one of the set up masks do I now have 4 remaining or have I still used up a mask even though it was deleted giving me 3 remaining? Thanks

Current situation: I have 2 monitors. I have the option of auto hide taskbar in desktop mode turned on. On the primary monitor, when I maximise firefox window( not full screen, the button between close and minimise, looking like a square), and hover my cursor towards the bottom, my taskbar doesn't unhide. However when I unminimise( clicking the middle button on the top right again), the taskbar unhides correctly. Also to note, my secondary monitor works completely fine ie, when firefox is maximised I can unhide taskbar on hovering near the bottom.

Well this happened after a Firefox Update with that i also suspect that using a User.js can aslo cause it would you like to look for the problem pls.

```js // /* You may copy+paste this file and use it as it is.

*
* If you make changes to your about:config while the program is running, the
* changes will be overwritten by the user.js when the application restarts.
*
* To make lasting changes to preferences, you will have to edit the user.js.

I am trying to block out the new little "stick marks" that post while I try to log on to a site that that I need to "google" and log on to. I tried to sign out of all the "outside sites" that want to log on, but there are sites that I need to log on to and have done this in the past. I usually go to these sites because they are important to my transacting business, accessing my bank, places I pay my bills, etc. If I want to get to these and order or pay a bill, I have to unblock each one of them??? How do I do that? If a credit company wants to contact me, they cannot do this even if we have contacted each other previously? Really?

How do I undo this already-marked system and get out of it? As you can guess, I am old and not up with the times. Please simplify your answers so a not-technical person can understand it.

Hi. I bought new pc, and i'm trying to set up mozilla with all my passwords and bookmarks, from old pc. But after i logged in, bookmarks and passwords dont appear in a browser. I had so much important stuff there that im now kinda scared. Thanks for any help in advance

I recently had to factory reset my computer and had to download and sync my firefox account all over again. It's been a week and firefox is still syncing, none of my bookmarks, add-ons, history or top sites on the new tab are showing up. Thankfully, it appears that most of my passwords have been synced.

I've read some other threads for tips and can confirm that I don't have this account logged in to other devices and I don't have a vpn or proxy running. I am able to obtain the sync logs but I have no idea how to read it.

How can I make the bookmarks, add-ons, history and top sites sync faster?

FF 109 added a new addons-button (jigsaw puzzle icon) in the addons-toolbar. Can we hide it with a specific variable in about:config, or by creating a specific variable there?

My extensions take up a lot of space in my toolbar and I'd love to hide all of them. However - every 'solution' to the problem tells me to right click the extension straight from the toolbar and click 'Hide from Toolbar'.

I do remember this option existing, however I couldn't find it since last update and I'm assuming it was removed. Is there any way to use it again?

^ (Small note, It would also be lovely if I could add them to the Extensions add-on in the toolbar, as that would really be a better use for it other than overflow)
