Firefox-mienskipsfoarum

When I play games like classic.minecraft.net or krunker.io, the pointer speed is very slow. So I would like to know if there is a way to change the pointer speed of firefox.

The data displayed in firefox jumps up and down far enough that I can not read it. This is a new O/S and I just found the keyboard was set to UK, but I don't think that this will change the scroll wheel input to make it jump up and down. But maybe?

Recently, yesterday, the Roboform extension stopped displaying in Firefox with the other extensions next to the address entry bar. I have rebooted the system and deleted and reinstalled the Roboform extension, but it still does not show and it stopped allowing for login password selection.

Running Linux-Mint on my laptop. Trying to run an epson ET-2400 ink jet Printer. Need Driver for printer. I have seen some information about software that needs to be added to "talk" to the printer but I cannot find it now. Please someone help.

ad blocker on mac laptop does now show up in mozilla firefox extensions or manager, I opened the puzzle icon but only grammerly shows up, I know I have ad blocker because i have websites saying so and i paid for it annually,

Although I have checked "Always Ask" to specify my download location, duplicates are still being saved in "Downloads". I recently "upgraded" to Windows 11 but do not know if it is connected. FF version 138.0.3 (64-bit). How can I prevent this please?

MY FF recently updated to version 1380.1 (64bits) and my Sidebar Bookmarks are gone. That is I have to manually put them back every time I now start FF. I want them to always show when I start FF. When I need extra screen space, I would click the X and they'd disappear for that session. And when I was done, I'd click on View - Bookmarks they'd be reinstalled. And when I shut FF down and returned later, they'd be right there where I need them.

My question is, how do I get back to that setup?

Is it possible to add a border color to the Bookmark popup menu using userChrome.css? I have search all over but it seems there is no code for adding the border.

I'm a therapist and within the last week (maybe since an update?) when I try to do a telehealth session from any website - Ensora Mental Health (my EHR), Simple Practice, Sessions by Psychology Today, Google Meet, Zoom - the client can see me but can't hear me, and I can hear them but can't see them (black screen).

I've checked all video and microphone permissions, Microsoft and all drivers are updated and mic and camera are functioning (they can see me). I tried changing the enhanced tracking to add exceptions for the sites (didn't work).

Please advise.
