Bug 1672375 - Get rid of unused variable in TelemetryUserInteraction.cpp. r=chutten This variable was used in a MOZ_DIAGNOSTIC_ASSERT, but that kind of ASSERT is a no-op outside of Nightly, DevEdition and debug builds. Differential Revision: https://phabricator.services.mozilla.com/D94323

Bug 1672146 - Make UrlbarProviderSearchTips deal with the update manager not existing. r=harry In the bug, Gijs suggests checking `AppConstants.MOZ_UPDATER`, but the stack shows that `Cc[aContract]` isn't defined, so it seems better to check for that instead. I'm not sure how or whether it's even possible to write a test where there's no updater, so I haven't added one, and in the case where there is an updater, that's covered by our existing tests of course.

Bug 1671729 - Gather telemetry on page load and request animation frame callback time r=bas,smaug,Dexter Current page load telemetry probes are insufficient in performance RUM testing. FX_PAGE_LOAD_MS_2 will stop the timer when the user switches tabs or navigates off the page, while the current navigation probes include all content including about:blank, about:newtab, moz-extension, etc. This patch adds support for the following probes which do not suffer from those limitations: PERF_PAGE_LOAD_TIME_MS PERF_PAGE_LOAD_TIME_FROM_RESPONSESTART_MS PERF_DOM_CONTENT_LOADED_TIME_MS PERF_DOM_CONTENT_LOADED_TIME_FROM_RESPONSESTART_MS PERF_FIRST_CONTENTFUL_PAINT_MS PERF_FIRST_CONTENTFUL_PAINT_FROM_RESPONSESTART_MS PERF_REQUEST_ANIMATION_CALLBACK_PAGELOAD_MS PERF_REQUEST_ANIMATION_CALLBACK_NON_PAGELOAD_MS Differential Revision: https://phabricator.services.mozilla.com/D94004

Bug 1672172 - Fail parse if JS line number exceeds 4B. r=jandem Fail parsing if line number (including initial offset) overflows the uint32_t line number. Source length is capped at 4B characters so this change only affects cases of inline-scripts with billions of lines which is not a realistic case, even for generated code.
