Symptoms of those crashes are freezing tabs and even frozen main Firefox UI. This is on a Surface Book running the latest Windows 10 stable release with all updates (aniversary update level). I'm using accessibility, but the two crashes that I submitted so far, with different signatures, didn't have a11y specific stacks in them. Here's what happened: 1. Visited the Open-Xchange instance at my e-mail provider https://mailbox.org. Note you need a login for this, so probably not directly feasible. My account is set to automatically open the E-Mail app. The freeze occurs right when e-mail gets displayed after logging in. Keyboard freezes, mouse clicks only sporadically come through, so do touch gestures. Sometimes one can close a tab, but the Firefox UI doesn't really recover. After a long time, it is possible to quit Firefox alltogether. ": Upon next start, I got a notification telling me that I had an unsubmitted crash report. That is this one: bp-f0f440f3-20ac-44ae-8e33-0c13c2161011 3. I then went to the https://open-xchange.com site and chose the "Try Now" link. They have a demo setup that one can try. I chose the first user "David". 4. After clicking around a bit in the Portal, trying to open a few of the widgets, a freeze also occurred, it just took a bit longer. 5. After successfully shutting down Nightly again, I got another notification that I had an unsubmitted crash report. That'll be: bp-9902f296-5948-4154-b8db-bda6d2161011 Since the two signatures differ, but the root cause is in the same web application suite, I'm submitting the report like this.
