In a followup to bug 1443749, I discovered that a remote browser (in sidebar) did not have currentURI set correctly after a document was loaded. This likely also affects browser and page actions, though we don't hit this specific issue as we are not touching currentURI. By adding: "browser.webProgress;" after inserting the browser into the document, RemoteWebProgress is created and currentURI is set correctly. We shouldn't depend on the consumer of the remote browser doing this.

This is going to need uplift to 60 in order to fix issues with sidebar extensions, such as Notes and Tab Split.

Comment on attachment 8958277 [details] Bug 1445080 - fix handling of remote web progress for non-tab browsers, Approval Request Comment [Feature/Bug causing the regression]: remote-browser [User impact if declined]: non-tab browser used in sidebar reloads too often [Is this code covered by automated tests?]: yes [Has the fix been verified in Nightly?]: not yet [Needs manual test from QE? If yes, steps to reproduce]: Verifying fixes that resulted in these bugs would be good even though there is a test. QA for notes and tab-split has several github issues with STR [List of other uplifts needed for the feature/fix]: none [Is the change risky?]: Risk is moderate. [Why is the change risky/not risky?]: The change is simple, however it affects all remote browser elements [String changes made/needed]: none

This seemed to fix the problems that Notes had, I am gonna go through the bugs we have in Github and SoftVision will do another run at this. Thank you!

Comment on attachment 8958277 [details] Bug 1445080 - fix handling of remote web progress for non-tab browsers, fix issues with sidebar extensions, beta60+

We've retested the Firefox Notes and Tab Split issues filed from the corresponding GitHub repositories and the issues are no longer reproducible on latest Nightly build 61.0a1 (Build ID: 20180321220044) and latest Beta 60.0b5 (Build ID: 20180319175655), on Windows 10 x64, Mac 10.13.3, Ubuntu 14.04 x64 and Arch Linux 4.12. From the 2 webextensions side, this change fixed the problems. However I'm not sure how can we test if the currentURI is set correctly, and confirm that everything fixed in this issue is as it should be. Shane, can you please provide a minimal test case and some information regarding how we can QA this?

An automated test was added for currentURI. The only manual verification necessary is that the extensions were fixed.

All right, we are good then. Thank you!

Based on previous comments, this bug was verified on Nightly 60.0a1 and Beta 60.0b5. Removing the qe-verify+ flag.
