We recently came across a situation in our markup where we wanted whitespace in the markup for readability, but we didn't want that whitespace represented between the elements.
We found a fix that suggested using font-size: 0 in CSS to eliminate the whitespace. That worked fine in Chrome, but we found that in Firefox, the containing element no longer scrolled with the mouse wheel or arrow keys! Apparently Firefox's scroll speed is proportional to font-size.

One team reported that Capistrano can't deal with host aliases in .ssh/config. Others use host aliases with capistrano without trouble. The problem could be related to multiple host aliases. All this led to the statement:
If you are working with EY, you should go all alias, all the time.
Problems with JsUnit and Firefox 3.5. From Adam:
If you're planning to use JsUnit, or you already use JsUnit and you plan to upgrade your Firefox to version 3.5, you may run into this problem. Apparently the security settings in Firefox were updated in 3.5 to restrict file access in a way that stymies JsUnit. If you don't fix this JsUnit will fail to open test files, and will simply hang on tests runs, with no error output. To fix it:
- type 'about:config' in the Firefox URL bar
- Filter by 'security.fileuri.strict_origin_policy'
- Set this to false

- In response to our ask for help, Ray Baxter answered us in code with a script called Firefoxen. "It’s a script to automatically configure multiple installations of Firefox so that they open with different profiles." You can grab Firefoxen on GitHub. Thanks Ray!
IE7 sends odd
Acceptheaders (*.*instead of an explicittext/html) which can cause undesired behavior in Rails. Someone suggested manually setting the format in abefore_filter:params[:format] ||= 'text/html'
This was discouraged because it can cause problems elsewhere. A better solution was to put the html format at the top of any `respond_to` blocks:def show respond_to.html # run by default when type cannot be determined respond_to.js end
The Ruby MySQL Gem version 2.7 leaks memory for very large queries. The solution is to remove the 2.7 gem and manually install version 2.8 from source. This library is no longer a gem and must be installed from the mysql-ruby-2.8 tarball.

"As a followup to Firefox SSL certificate problems..."
It turns out that our server running nginx had an old version of OpenSSL installed. Upgrading OpenSSL solved the problem.
