Yesterday, we had a customer reach out to us for help on an issue they’d encountered while writing code to interact with Microsoft Edge windows. Their script enumerated every window in the system, looking for those with Microsoft Edge in the titlebar. They were surprised to discover that the script didn’t recognize any of theirContinue reading “Recognizing Edge Windows”

Debug Native Messaging
Prelude Last month, an Enterprise customer reached out to report that a 3rd-party browser extension they use wasn’t working properly. Investigation of the extension revealed that the browser extension relied upon a NativeMessaging Host (NMH) companion that runs outside of the browser’s sandbox. In reviewing a Process Monitor log provided by the customer, the SupportContinue reading “Debug Native Messaging”
Edge Command Line Arguments
Microsoft Edge offers broad variety of configuration options via Group Policy (for Enterprises), the edge://settings page, the edge://flags page (mostly experimental options), and finally via command-line arguments that are passed to the msedge.exe executable. This list of sources is roughly in order of stability and supportability– earlier choices change less often (and with more notice)Continue reading “Edge Command Line Arguments”
Great Bug Reports via “Recreate My Problem” in Microsoft Edge
When you encounter a problem in Microsoft Edge, you can let the team know about it using the … Menu > Help and Feedback > Send Feedback command. Clicking this menu item will open Edge’s feedback wizard, which provides tons of options about what information will be submitted along with your bug report. Generally speaking,Continue reading “Great Bug Reports via “Recreate My Problem” in Microsoft Edge”
Spooky: Enhancing Dark Mode in Chromium
I am not really a fan of Dark Mode — I like my screens bright and shiny. But it’s October, and it’s sometimes fun to make things dark and spooky. Some users of my Show Browser Version extension wanted it to better support Dark Mode– the default text colors didn’t work well when the browserContinue reading “Spooky: Enhancing Dark Mode in Chromium”
Practical Time Machines
Many “emergency” situations in our modern world would’ve been easy to fix had they been foreseen in advance. If only we’d known what was going to happen, the badness could’ve easily been prevented. Unfortunately, when problems are discovered only “as they happen” in production, everyone must race to minimize the damage and put out theContinue reading “Practical Time Machines”
Determining OS Platform Version
In general, you should not care what Operating System visitors are using to visit your website. If you attempt to be clever, you will often get it wrong and cause problems that are an annoyance for users and a hassle for me to debug. So avoid trying to be nosy/clever if at all possible. ThatContinue reading “Determining OS Platform Version”
Download Blocking by File Type
Last Updated: 19 December 2022 I’ve previously gushed about the magic of the File Type Policies component — a mechanism that allows files to be classified by their level of “dangerousness”, such that harmless files (e.g. .txt files) can be downloaded freely, whilst potentially-dangerous files (e.g. .dll files) are subjected to a higher degree ofContinue reading “Download Blocking by File Type”
Per-Site Permissions in Edge
Last year, I wrote about how the new Microsoft Edge browser mostly ignores Security Zones (except in very rare circumstances) to configure security and permissions decisions. Instead, in Chromium per-site permissions are controlled by settings and policies expressed using a simple syntax with limited wildcarding support. Settings Page’s Site Permissions and Group Policy Internet ExplorerContinue reading “Per-Site Permissions in Edge”
Client Certificates and Logout
Last Updated May 16, 2022 Back in May 2020, I wrote about Client Certificate Authentication, a mechanism that allows websites to strongly validate the identity of their visitors using certificates presented by the visitor’s browser. One significant limitation for client certificate authentication is that there is no standards-based mechanism for a user to “log out”Continue reading “Client Certificates and Logout”
