    Firefox is extremely sluggish and flash notworking

    Some might say flash not working is good lol. But I need it for the odd site. Tried uninstalling etc etc.
    This is 16.04 version ubuntu mate clean install.

    Firefox, well, unbelievable lag. Clean install of this too. i.e.new profile.

    Machine is a sempron 1.2 gig with about 1.2 gig memory. Other stuff runs fine like libre office.

    Any ideas.

    Have you set Flash as click-to-play (or something equivalent)?

    In my about:config, I have
    Code:
    plugins.click_to_play;true

    Re: Firefox is extremely sluggish and flash notworking

    Unfortunately the only way to get decent flash support on Linux is to use one of the Google Chrome family of browsers. Chromium is available in the Ubuntu repositories. I've been using Slimjet, which is based on Chromium but includes more privacy and security options such as being able to easily disable WebRTC. It also includes a built-in ad blocker which seems to work pretty well.

    http://www.slimjet.com/

    The only problem I've had is that Slimjet will occasionally bomb out on startup out saying it can't open its local database. The "fix" is to delete the file "~/.config/slimjet/Default/Web Data" when this happens. I have a command for this set up up as an alias in ~/.bashrc.

    Code:
    alias sjfix='rm ~/.config/slimjet/Default/Web\ Data'
    Also since Slimjet is not in the repositories, or available in a PPA as far as I know, you need to manually install updates.

    I still prefer Firefox overall but it's stuck with an ancient version of Flash that never worked all that well on Linux. (Firefox is also agonizingly slow initializing add-ons. Slimjet is much faster.)

    Re: Firefox is extremely sluggish and flash notworking

    Well, I had not tried playing flash content yet since I installed ubuntu-mate. I have ubuntu-restricted-extras installed.

    For ex http://www.bfmtv.com/mediaplayer/live-video/ wont play, I have a white triangle "Play video" over a black background that does not do a thing. To note, https://helpx.adobe.com/flash-player.html shows the animation. The latest shown here is the one I got : http://www.adobe.com/software/flash/about/ Shockwave Flash 11.2 r202.
    I've read some content (such as the one I tried above, ie some content from French TV) require pipelight but I cannot be too bothered about it, youtube and dailymotion work although the fans quickly start blowing up. This VM had 3GB mem, 2 cores and 128MB video mem with 3D acceleration (max possible mem).

    Which site cannot play for you for ex ?

    Edit : once again I'm hit by my devils, search and experiment with an open tab that I do not reload before posting, sorry

    Check your CPU flags:

    Code:
    inxi -f
    SSE2 is needed for Flash.

    Even if Firefox doesn't play nice with some Flash sites, that doesn't explain the overall sluggishness unless it's with specific reference to those Flash sites

    When it comes to "extremely sluggish" you can try to switch from Marco Software Compositor (by default in Ubuntu MATE) to No Compositor.

    When I go to the Adobe site with firefox 46.0 I see, "You have version 21,0,0,242 installed."

    I can see the Flash on at least one of the sites that bapoumba mentioned. (I only checked one.)

    Running Ubuntu 16.04. This is what I installed for flash.

    Description: PPAPI-host NPAPI-plugin adapter for pepperflash
    The main goal of the project is to get PPAPI (Chrome) plugins
    working in Firefox (and any other web-browser supporting NPAPI plugins).
    It implements a wrapper which behaves like
    browser to PPAPI plugin and implements NPAPI plugin interface
    for browser to use.
    .
    This particular implementation doesn't implement any sandboxing,
    which means any malicious code can break through plugin security
    as there are no additional barriers. This is the same level of security as
    NPAPI Flash have.
    .
    Flash plugin for Linux provided by adobe stopped at version 11.2; for
    chrome/chromium users there is pepperflash plugin but it's not supported by
    firefox/iceweasel/other browsers.
    .
    This package allows one to use the Pepper Flash plugin from Chrome
    in NPAPI web browsers.
