Firefox won't remember my passwords

October 6th, 2010

Had a weird one with Firefox 3.6 that I thought I’d share with you all.

I wanted to test some web site stuff and so I deleted all my browser cookies to make sure I appeared to the site as a new user. This action also had an unexpected side-effect of deleting all my saved passwords. Looking back at the situation there may have already been some file corruption which was made worse when I deleted all my cookies. I looked at my saved password file and it appeared to be a similar size to usual except there didn’t seem to be anything in there.

Also, the corruption had a very visible effect. Now whenever Firefox asked if I wanted to save my password I clicked Remember but the button didn’t do anything. It clicked down and up, but the bar on which it was placed remained. Needless to say it didn’t remember any new passwords either.

  1. Shutdown Firefox.
  2. Went to C:\Documents and Settings\myusername\Application Data\Mozilla\Firefox\Profiles and moved my profile directory (b0eqore3.default) to the desktop.
  3. Started Firefox.
  4. Firefox reports it is already running and won’t start.
  5. Checked process list and Firefox is definitely not running.
  6. Shutdown Firefox.
  7. Moved my profile directory back to its original location.
  8. Firefox started normally and passwords were back!

Even though I effectively did nothing it all worked and I haven’t had a problem since. You have to love computers don’t you!

Difficult to remember html

October 4th, 2010

From time to time there are various pieces of HTML I need, but I just can’t remember the syntax. So here they are as a brain dump.

When you make a copy of a web page all the links are usually from some remote location’s perspective, so to make your browser think you are looking at the remote site you can add a base reference. Now relative links (and usually links to images) are taken from the artificial base instead of the actual base which is usually on your computer.

<base href="http://example.com"/>

If you want a redirect a visitor to another page there are several methods, but the simplest is to use static HTML. This method requires no extra work to be done by the web server as it can just deliver the page as normal. The content holds 2 items separated by a semi-colon. The first number is the number of seconds to wait before redirecting to the specified url.

<meta http-equiv="Refresh”
content="3; url=http://example.com"/>

They may seem like easy to remember tags, but I find myself looking them up all the time. Now as least I can look them up on my site instead of hopping over to Google.

Eclipse 4.0 - SDK - New and Noteworthy

September 17th, 2010

I’m building quite a rich list of Eclipse New and Noteworthy documents. This one is for Eclipse 4.0. As far as I can work out there is no project name yet for Eclipse 4.0. Although it is a new structure all the new features are the same as Eclipse 3.7. This release is primarily for developers who want to check for compatibility issues between the previous 3.x versions and the newer version with regards to their plug-ins and RCP applications. Most non-Eclipse developers i.e. developers who use Eclipse to write programs other than Eclipse are expected to go for a later 4.x release.

Well I bet you’re dying to know what’s in it so without further a-do:

There’s no project plan yet, so no dates. McQ has a entry on the Eclipse blog which outlines the changes.

Mnemonics and Acronyms

August 31st, 2010

Like a lot of other I.T. professionals I’m dyslexic and as a result I find it difficult to remember spellings and lists or groups of ordered items. What good is trying to remember SOHCAHTOA if you can’t remember how to spell it! So I would like to use this article to document all the Mnemonic Acronyms.

I’m describing a rhyme or saying where the first letter of each word in the rhyme or saying is a memory trigger to help you remember another word. English is big and I’m sure there is a particular word which describes what these are but I don’t know what it is, does any one know?

So here is my current list. Please add more to the comments and I’ll incorporate them into the article.
