Thread: Firefox very slow to render page

  1. Firefox very slow to render page

    I have FF 3.0.10 on Vista ultimate with a fast CPU and 4 gigs of RAM.
    Just the last day or two FF has really slowed down the page display,
    especially when there are lots of components e.g. PHPMyAdmin - with
    its rows of icons - displays one icon at a time like an old printer -
    even
    when I'm looking at it on localhost. Another slow example would
    be PHPBB pages.

    I am not sure what I've changed. I've tried FF in safe mode. No good.
    I've tried turning off the firewall. No good.

    Sorry. Maybe I wasn't clear. I mean PHPBB bulletin boards and
    phpMyAdmin database management pages. The latter in particular often
    displays several hundred 16px icons and it's almost as if FF is
    downloading each one individually.

    Hang on... that's given me an idea... maybe that's what's happening.

    Right. I've just captured the packets and here's a sample of my GET
    requests for one view in PHPMyAdmin

    GET /3rdparty/phpMyAdmin/themes/original/img/b_drop.png HTTP/1.1

    Something's going wrong with the chat between FF and the server.
    Either FF is demanding a new file and not caching properly, or the
    server is failing to recognise that the file is unchanged. Seeing as
    it's happening on many sites, I reckon it's FF.

    Any ideas?

    Goddit. I opened about:config and turned caching back on. How it got
    turned off is a mystery, but I'm back up and running.

    Thanks for your help.
