Implementing form filling and accessibility in the Firefox PDF viewer

Intro Last year, during lockdown, many discovered the importance of PDF forms when having to deal remotely with administrations and large organizations like banks. Firefox supported displaying PDF forms, but it didn’t support filling them: users had to print them, fill them by hand, and scan them back to digital form. We decided it was time to reinvest...

Control your data for good with Rally

Let’s face it, if you have ever used the internet or signed up for an online account, or even read a blog post like this one, chances are that your data has left a permanent mark on the interwebs and online services have exploited your data without your awareness for a very long time.  The Fight for Privacy The fight for privacy is compounded by the...

Tab Unloading in Firefox 93

Starting with Firefox 93, Firefox will monitor available system memory and, should it ever become so critically low that a crash is imminent, Firefox will respond by unloading memory-heavy but not actively used tabs.

Archiving content Last month we removed a bunch of content from MDN. MDN is 16 years old (and yes it can drink in some countries), all that time ago it was a great place for all of Mozilla to document...

Hopping on Firefox 91

Hopping on Firefox 91 August is already here, which means so is Firefox 91! This release has a Scottish locale added and, if the ‘increased contrast’ setting is checked, auto enables High Contrast mode on macOS. Private browsing windows have an HTTPS-first policy and will automatically attempt to make all connections to websites secure. Connections...

How MDN’s autocomplete search works

Last month, Gregor Weber and I added an autocomplete search to MDN Web Docs, that allows you to quickly jump straight to the document you’re looking for by typing parts of the document title. This is the story about how that’s implemented. If you stick around to the end, I’ll share an “easter egg” feature that, once you’ve learned it, will make you...
