Dims bright webpages. Intended to be used with a _light_ theme, i.e. the background should be lighter than the text (but it can be medium grey or anything).

The code has a timeout at the top, you can enable that and see if it helps (it will) or enable the userstyle generating thing (also at the top) and you'll get a userstyle, and you can disable the usersrcipt on that page from then on.
I will try to include an update later when the script is delayed on a per-domain basis.
thanks for this UserScript ,very useful but on many sites like Google contacts or messneger.com it mostly fails.
