ฟอรั่มสนับสนุนของ Firefox

For over a year when i go to download something it defaults to the downloads folder instead of asking me where I wasnt to download. I'm about fed up with FF. it's been a great 10 years but this issue along with 80% of my sites not loading or working will lead to me jumping ship. Please help!

Hi all Gurus,

I have been trying and searching but I could not find a suitable answer. Figured I try asking the question here.

Is there anyway or what is the policy that I can configure to disable the "New Tab Ctrl+T" function on the menu please? Attached image.

Video download helper is installed but icon is missing from toolbar and cannot be found where I'm told to look when I google the problem (i.e., view/toolbars/customize). Nor can I drag it to the toolbar from where I find it when I look under triple bar/addons and themes in the upper right corner of the toolbar. Where else should I look to find it?

I make themes for themes for firefox using firefox colors extension. I want to know how to change the text colour, background colour, etc of right click menus ( see image attached.

Every few days I get a notification that Firefox will be quitting in 120 minutes. However, there is no option to tell Firefox not to do this. I checked my settings and couldn't find anything about this either. My settings also say that my version of Firefox is up to date, so Firefox is not restarting for an update. Is this happening for other people? How do I tell Firefox not to quit without my permission?
