Firefox 技術支援討論區

I'd like to add Firefox to Adobe Dreamweaver for site design viewing. When searching Windows for Firefox.exe I don't see it in Program Files or Program Files (x86). Firefox is installed and used daily. Can someone tell me where it's located in Windows 10?

For the last week or so, I've been having an issue with media not playing properly on websites. Specifically, when I read webpages which have embedded Twitter images or videos, I see the message "The Media Could Not Be Played" where a screenshot of the media used to appear. There is a blue "Reload" button, and when I click it, I can briefly see the screenshot for a split second before "The Media Could Not Be Played" re-appears.

With YouTube videos, they fail to play and I get the message "An error occurred. Please try again later". This happens with both embedded videos on webpages, and directly on the YouTube website itself.

All of this media works properly when I open the same pages in another browser like Chrome. I would prefer not to switch browsers. Is there a way to fix this error?

How can I do keyboard shortcut, "Text encoding options", then "Unicode". I have it on toolbars. Like on screnshot, I pint mouse, then I need to select Unicode, which is bothering. I am opening many many pages, which are always different than unicode.

Does the latest version of Firefox allow you to have the tabs below the bookmarks. In the past, new versions place the tabs above and would not allow you to move them to the bottom. I have not updated many months, because I like the tabs on the bottom.

I download a lot of images, and I would like to remove a bunch of entries from the context menu for images (entries which I keep clicking by accident). Can I do that?

Thank you.

I am using FF 71, which I will not be upgrading. Indeed, I want to return to a previous version to stop the upgrade nagging.

Greetings, My old computer hard drive got damaged and the computer will not startup. I have a new computer. I never knew I could connect my mobile phone to retrieve my bookmarks and passwords, etc. If possible I need to recover my passwords to my Firefox browser on this new computer. I signed into my Firefox account to see if I could locate them. But have no clue if they were there or not. Is it possible for you to send them to my email or mobile phone on file? My new computer is using the IP address, so it should not be an issue to track and verify my IP location with my email address. Thanks, Kenneth McGowan [removed phone# from public]

Team,

   Recently I logged into my Firefox account as to where I had likely over 60 URL favorites fully categorized.  It now apparent that I would like to have a systems administrator to see if we could manually look through my history and have my old favorites I have in the system able to restore and shoot back to me. Its worth it as It took 2 weeks to have these favorites created and organized and I am sortof at a work stoppage due to this issue.
 Anyone ever had this kind of issue escalated or have a techie with mozilla able to restore back something that may have been over-written or over synced and now when I login no longer shows my URLs that I have all categorized and favorite-ed?

When I zoom in (with ctrl+= for example) images are rendered with heavy interpolation / blurring. Usually I want to see individual pixels as discrete, blur-less squares.

Is there any way to change it so Firefox renders without interpolation? I am using Firefox 71.0 Operating system: Linux Mint 19.3
