:ochameau, maybe you can take a look since you worked on bug 1151909? Let me know if you need help / if the problem is something in RDM.
The STR seems to be really about the RDM. The picker stays on while the RDM is turned on. But the content document is suffled around, which ends up breaking the highlighter. The highlighter markup stays there for ever. My patch from bug 1151909 starts listening for window-ready instead of navigate. I imagine the RDM triggers navigate event when turning it ON? And also will-navigate which are used in some other places in highlighter galaxy. I tried to cleanup things on window-destroyed, but it seems to be tricky. I'm wondering if we should just cancel the picker before toggling RDM?
Here is something on top of bug 1151909, but with that, the picker button on the top left of the toolbox stays ON whereas it has been cancelled. May be we should also change the navigate to window-ready to try to restore it? Before going deeper into these actors I would like you feedback on just cancelling picker on RDM toggle.
Assigning this to you Alex since you already took the lead on it. Gonna needinfo zer0 just in case he has other ideas on the fix.

I agreed with Alex that this seems to be really about the RDM. I think the culprit here is the swap frame loaders, that "confuses" the highlighter. I tried to apply the patch attached, but I got a `this._highlighter is null` if I try to reuse the highlighter once I exit from RDM (assuming I've the inspector enabled in RDM before close it); or vice versa (entering in RDM with the inspector enabled on the page, and then try to re-enable again in RDM).
I'll take a look at what RDM is doing here.
jryans: is this likely to be upliftable to 53? Should we fix-optional or wontfix it for 53?
(In reply to Randell Jesup [:jesup] from comment #9) > jryans: is this likely to be upliftable to 53? Should we fix-optional or > wontfix it for 53? I think we'll be able to uplift to 53, at least so far. I'll take this over from :ochameau.

It seems like the root cause here is that `swapFrameLoaders` path used by moving tabs between windows, toggling RDM, etc. fires `pageshow` events, which is one input we used to emit `window-created`. We could try to distinguish or ignore _these_ pageshow events from _other_ pageshow events, but that feels a little more complex than needed. I think we can attempt to remove any inserted highlighter on `window-created`, and that's probably good enough, but I might be missing a user flow here.

Sorry if I wasn't quick to review it, but I wanted to check if this patch was fixing also some other scenario I was working on, or simplified existing patch.

I am a bit concerned that the states in highlighter-overlays might not be cleared as a result of the current fix. zer0, can you check if this is the case? If so, possibly file a follow up.

If so, possibly file a follow up. Can I proceed to uplift this current fix to 54 and 53? Or do you want more investigation first?
Having Matteo double check this and clearing it for uplift.
To me it's fine as is. There was a slightly doubt about some highlighters in highlighter-overlays, but I don't think it would trigger any major issues.

Hi Brindusa, could you help find someone to verify if this issue was fixed as expected on a latest Nightly build? Thanks!
Hi, I tested this on Windows 10 with the latest FF Nightly 55.0a1(2017-03-14) and I can confirm the fix, I'm no longer able to reproduce this issue. Please note that I tried to reproduce this on Mac and Ubuntu but is not reproducible. I will mark this as verified fix.
