• Don’t Hide Version Numbers It breaks user expectations with no real benefit, and makes it hard to tell if you’ve actually gotten the latest security fix.
• Firefox Thinks It’s Running an Older Version Than Last Time (But Isn’t!) Look for the compatibility.ini file in your Firefox profile, and delete the LastVersion line.
• Gmail on SeaMonkey Yes, you can still connect it after the switch to OAuth2. You need to create a placeholder account first, and find the right settings, which Gmail doesn’t seem to tell you anymore.
• How Thunderbird’s Scam Detection Works (2005) (Obsolete) Tracking down what causes Mozilla Thunderbird to label a message as suspicious, as well as how to train it to ignore emails that you know are legit.
• Move Email Archives to a New Account Thunderbird, Vivaldi, Apple Mail and Outlook can move messages from one IMAP account to another. Just drag and drop! But Gmail makes it a bit more complicated.
• On Broken HTML From time to time the idea is put forth that less common browsers need to start dealing with bad code. There are two problems with that view.
• Pure CSS Buttons As part of a minor site optimizing kick, I replaced the validation labels with something smaller, less obtrusive, and directly on the page. I tried to duplicate the look of the classic antipixel-style buttons in CSS.
• Reverse the Colors when Viewing a Web Page Not as good as a real dark mode, but you can easily reverse the colors on any website you’re viewing, turning light pages dark and dark pages light.
• Simple Browser Categorization (Obsolete) Sometimes you want to know exactly what software people (or bots) are using to view your website. Sometimes all you want to know is which rendering engine’s quirks you need to cater to.
• Tell Firefox to open Gemini links with your favorite client You’ll need to click on a Gemini link to get the config options, and then you can choose what to open it in.
• Thunderbird Gets a 400 Error Setting Up Gmail Normally there’s no good reason for your email client to accept cookies. Except here.
• Toolbars That Phone Home (Obsolete) I installed the Firefox versions of four toolbars and used netstat to see when they connected.
• Useful Bookmarklets A collection of bookmarklets that I’ve found useful.
• User-Agent Spoofing Explained Let’s say someone decides that they’ll only allow blondes into an event. Depending on how its done, UA spoofing can be like wearing a blonde wig, or it can be like a brunette wearing a badge that says “Blonde.”
• Web Design is Like Pizza A lot of pages aren’t as specific as the authors think they are. When you write code and test it on only one browser, you’re not testing that the code is correct, you’re testing that that browser makes the same assumptions you do.
• Webslices and Microsummaries (Obsolete) Both features have since been removed, but they offered and interesting way to let visitors know when a site had been updated.
• Why is NginX serving different localhost sites to Chromium vs. Safari or Firefox? If you have NginX listen to IPV6 in one localhost server {} block, listen to it in all of them!
