• When migrating from MS EDGE (Flash) for Firefox on a PC laptopis it is necessary to download and install Adobe Flash Player to see the live streaming?

  My computer ASUS laptop was originally a Windows 8.1 OS, and I used the latest version of IE as my browser. I then upgraded to Win 10 and used MS Edge as my browser for the last year, or almost. I know that Adobe Flash Player is embedded or pre-installed in Win 10 or an edge. I'm now migration to Firefox. I was able to watch the live broadcast in MS Edge (athletes on Canadian channels TSN and Sportsnet). Streaming live isn't working / start now that I use Firefox. I thought that since Flash Player is already "installed" there was nothing else I needed to do to watch the live broadcast. Query - do I need to download and install a version of 'fresh' Adobe Flash Player to work with Firefox, well there is a 'work' Flash Player who continues to work with Mrs. Edge?

  Yes, Flash must be installed especially for Firefox.

  Other browsers use their own version of Flash and with some, it is integrated or the Flash plugin is supplied with the browser. NPAPI - Plugin for Firefox and other browsers based on Gecko, PPAPI for Chrome, Opera, Vivaldi and Edge, ActiveX for Internet Explorer

  Firefox needs the NAPAPI - version of the Flash Plugin. which is a proprietary owned by Adobe - not open source as with the Mozilla mission.

• My version of Firefox is updated, I restored to default settings Firefox, restarted, I downloaded the latest version of Flash and it won't work, it crashes...

  Mac, OS x 10.6.8 (updated), Firefox 28.0 (updated). Adobe Flash has been downloaded and no videos will work on all web pages using Firefox. I have reset the settings by default and restarted Firefox. I get the message that Adobe Flash broke down. Shut down the computer, restarted. Same thing. Uninstalled Flash and videos run but very agitated, jumps of 5 second increments after freezing. Firefox hangs and must be stopped by force. Installed an older version of Flash and it will work, but I get a warning that it is vulnerable. I crossed it several times and checked all my updates and they are the most recent available. Videos are running on either the latest version of Safari.

  I'm happy to have helped. Thanks for laying back.

  Remember to follow any progress, because I hope a fix will be available and you do not want to stay on Flash 12 unnecessarily.

• Firefox adds the extension jpeg for jpg images

  Whenever I have save an image through Firefox for Android, it adds an extension of JPEG, resulting in the FILENAME argument. JPG. JPEG. Since most Android applications don't recognize JPEG, I have to go into a file manager and rename the JPEG in JPG, until it was useful.

• How to replace firefox by automatically disabling the extensions such as Adobe and 1 password

  Firefox updated to the last version 41.0b1 beta how the Add - it automatically sign off three extensions,.
  -1Password
  -Adobe Acrobat
  -Avast Internet Security
  How can I replace the function disable if I can use these extensions in the latest version?

  41 of Firefox requires that extensions be signed by Mozilla, which follows a brief review process. Probably the publishers of these Add - we'll take care of this before Firefox 41 is officially released in about 5 weeks.

  If you want to run the current version, Firefox 40.0.2, instead of the beta-test version? It does not block unsigned extensions. You can enter here (scroll to your preferred language): https://www.mozilla.org/firefox/all/

  Alternatively, you can return a parameter that exists only in Firefox 41 to allow unsigned extensions. Which can be found here:

  (1) in a new tab, type or paste Subject: config in the address bar and press enter/return. Click on the button promising to be careful.

  (2) in the search above the list box, type or paste the xpi and make a pause so that the list is filtered

  (3) double-click the preference xpinstall.signatures.required to true to false

  One of these suggestions resolve the problem?
