Upgrade to Ubuntu 10.10 leaves some pictures in Firefox with a strange green hue

Version of Firefox is 3.6.15. After an upgrade, some, but not all, pictures have a greenish color to them. We're talking things like jpg, not flash or anything like that.

Fix:

In the Firefox address bar, type:
about:config

Yeah, yeah, you'll be careful. Set:
gfx.color_management.mode

to 0 (zero, if you can't decide whether that's "oh" or "zero"). My setting that had not been working was 2.

Flash player doesn't install in Firefox

Flash wasn't working for me in Firefox. At one point, I had installed several flash players via Symantic or Adept, until learning I should only install flashplayer-nonfree. I removed the other ones, but still no go. I tried downloading the package from Adobe manually, and installing via the command line, but got this error:

Please enter the installation path of the Mozilla, Netscape,
or Opera browser (i.e., /usr/lib/mozilla): /usr/bin/firefox

WARNING: /usr/bin/firefox is not a directory.

Here are the tricks to fix it:

• it seems the Adobe installer wants the actual numbered version of the firefox directory. "whereis firefox" didn't help me in this respect (as suggested on help forums). I ended up using /usr/lib/firefox-3.0.1 Yours might be slightly different. Why Adobe couldn't have indicated this in the installer... I don't know. Twits.
  
• when testing out whether flash works on something like YouTube, make sure you don't have something like the "NoScript" add-on preventing anything you may need. (D'oh!) I had to allow both youtube.com and ytimg.com in NoScript.
  

... that brings up the question whether flash was actually working all along and my NoScript was thwarting all my efforts. Oh, probably.

Need Rasterizing PDF Firefox Plugin

Not really a Linux issue, but a FOSS issue:

I'd like a pdf plugin for Firefox that automatically rasterizes a pdf that's being opened and inserts it inline, or opens it in a new window. This would be especially helpful if the pdf is only one page.

Rasterization at 72dpi would only be necessary as it is on screen. Therefore, rasterization should be pretty fast.

The reason I've thought of this: my city's library insists on providing links to things that look like posters or news articles, but it's a pdf. Therefore, I must open my laggy pdf software on my machine and go through that whole dialog.

Yes, I know, I could just get more RAM (but my motherboard doesn't play nice with RAM and I'm also frugal).

Sometimes no audio in Firefox pages with Flash

After having my system up and running for a while, I noticed that if I use Amarok and then open Firefox, videos in YouTube would have no sound. I figured this was just a wonky Kubuntu feature until I decided to actually research the problem.

This problem was solved if I would reboot the system and open Firefox and watch videos first (before playing music). The problem still was recurring, though.

Apparently this is more than an ALSA sound driver fight between Firefox and Amarok. It's actually a bug (see link).

How to fix your Firefox audio: open a terminal/console, and type

cd /tmp
mkdir /tmp/.esd
ln -s /tmp/.esd-1000/socket /tmp/.esd/socket
