Add-ons / Web Extensions
Addon Manager & about:addons
- As part of the QA verification on Bug 1602839 (meta issue related to locking down the add-ons sideload locations) we noticed that we were still accepting sideloading of extensions dropped into the application directory, Shane fixed this in Bug 1616545 (currently landed in Firefox 75, may be uplifted to 74 beta).
- The initial webpage that originated an addon installation is now stored in the addon db and sent as part of the abuse reports submitted by a user for the related extension (Bug 1610844)
- In Bug 1493620 Tomislav removed the creation of about:blank in the windowless browsers created to load the extension background pages
- In Bug 1614966 Shane moved the RemoteSettings prefs overriding out of ExtensionXPCShellUtils.jsm, which should make it simpler to re-use ExtensionTestUtils in xpcshell tests that would need RemoteSettings prefs to not be overwritten (e.g. see Bug 1612416)
Bugs fixed by contributors
- saroyanm fixed a bug that was preventing browser.permissions.request to work correctly when called from an extension popup (Bug 1432083)
- The newly added “beforeinput” event is now also available as “Event Listener Breakpoints”, thanks to farooqbckk
- The secondary footer in the Debugger was removed to save some space
- File tabs in Debugger can now be reordered with drag & drop, thanks to transfusion
- Command-Click to highlight and jump to a location, thanks to janelledement
- Instant Evaluation keeps getting better (scheduled for 75)
- Oriol added support for Proxy and Reflect methods in bug 1615861
- Logan added support for side-effects free DOM method (like querySelector for example)
- Highlight DOM element results (bug 1614549)
- Fixed issue with autocomplete case-insensitive matching in bug 1614841
- [WIP] Display the autocomplete above the input so it doesn’t cover the instant evaluation result (bug 1609942)
- `print` and `pprint` console helpers were removed, as they’re not standard, provided little values in comparison to console APIs and are not defined in other browser DevTools (Bug 1613845 and 1613843 )
- There’s now a way to disable autocomplete directly in the UI (Bug 1593607)
- Autoclose brackets – The Console panel input now respects the Autoclose brackets option. Console automatically inserts the corresponding closing element for quotes & brackets (bug).
- Eugene added proper rendering of ES6 classes in the console and debugger (bug 1592277)
- Alex made the Multiprocess Browser Console faster to open (bug 1605763)

- Focused filter buttons now look less `active` to avoid confusion, thanks to vtsty.dev
- Blocking network URLs now allows wildcard (*) patterns, thanks to duncangleeddean
- Borders got added between columns in network requests list for readability
- Temporary extensions loaded in GeckoView apps now also appear in about:debugging when connected to the device. Implemented by Luca Greco in bug 1596867.
- Historically, the framework part of the code that deals with client to server communication for DevTools has been called DebuggerClient and DebuggerServer.
This likely comes from the fact that the Debugger was probably the first tool to be based on a remote (client-server) architecture.
These objects have now been renamed to the more self-explanatory DevToolsClient and DevToolsServer.
- Julian tracked down an issue that had made the build for our documentation website fail for some time now (bug 1613368). The site was fine, but the latest updates were not being pushed to it. This is now fixed!
We’ll continue improving the onboarding docs on that site, and turn it into a simple, easy to digest, single page that points to other up-to-date resources wherever possible, to avoid duplication.
- Honza improved the table of content for the DevTools docs on https://firefox-source-docs.mozilla.org/devtools/index.html
In time, we plan on moving our internal technical documentation over to this site instead of https://docs.firefox-dev.tools . Our firef-dev.tools site will only contain a one pager getting started guide for new contributors.

New Tab Page

- Now ready to enable Pocket stories in the UK for 75
- Password manager:
- Show a dismissed login capture doorhanger when a user edits a password field (before submission)! (off-by-default until some follow-ups are landed)
- We no longer consider a login modified if there is a <button> and we fixed tabbing from a field eligible for password generation.
- The Fathom team is making progress on rules to identify new-password fields to offer password generation.
