Bugzilla

I've also experienced a whole bunch of other symptoms that I'll list. They are all intermittent.

 - When I hit Alt to show the menu bar (this is Windows) and then click something else or press Alt again, the menu bar doesn't hide itself again afterwards.
 - The awesome bar doesn't update or doesn't show at all.

 - The browser will just refuse to navigate. Often I'm trying to navigate to an `about:` page, but it won't even try to load it. Sometimes switching to another tab and switching back resolves the issue.
 - Unfinished search terms will be sent to the search engine from the URL bar. For example, I'll type "githib<backspace><backspace>ub rebase" and hit enter and I'll end up with a search for "githib".
 - I'll mouse over a link but no status panel appears.
 - The sound indicator on tabs will break. For example, a Slack notification usually makes the audio indicator on that tab appear only briefly. But lately it often appears and never leaves.
 - If I can get the Download panel open, clicking on the downloaded file doesn't open the file.
 - Tabs will appear to me to be done loading, but the loading indicator will be displayed forever.

:mconley was looking at a profile that I made when I was experiencing the issue at one point and made this interesting observation:

> So one kind bizarre thing kinda jumps out at me from the profile so far - a ton of requests for this gmail thing called cleardot.gif all seem to resolve around the same time ... some of those requests are over 1000 seconds old.

Things that I've tried:
 - Disabling all extensions.
 - Memory check. No errors detected.
 - mozregression. The issue is intermittent enough that I'm not 100% sure that I got the right commit, but [this is what I ended up with](https://hg.mozilla.org/integration/autoland/pushloghtml?fromchange=318de40d78d80454904084f214e28264dda6999c&tochange=eecfa46043c20f261e0f6e825609fcd658d49ea3).

The intermittence of the issue is really annoying for tracking the problem down. I think that I've been experiencing it the most frequently of anyone else that I know of (just the bug reporter and :aminomancer). But even so, sometimes the issue will just decide that it's done for the day and won't reproduce again until tomorrow. I do shutdown everyday, but a simple reboot does not necessarily make the issues come back.

I made an "anonymized" copy of my profile to send to :mconley and after purging addons, history, cache, bookmarks, etc, I was still able to reproduce the problem, but it didn't seem as bad. Like when I would double tap Alt and the menu bar would "stick", but would eventually hide itself properly.

When I try to reproduce the issue (say for mozregression), I had pretty good success reproducing it by following these steps:
 1. Launch browser.
 2. Hit Alt a few times and see if the menu bar gets "stuck".
 3. Start a youtube video playing. (If it ends while I'm still testing, I'd start a new one)
 4. Open some sites that link to lots of other sites (ex: News Aggregator like Hacker News) and repeat the following for maybe 10 minutes:
    a. Open a dozen tabs
    b. Tap Alt a few times to see if the menu bar "sticks".
    c. Open each of the new tabs, scroll down a bit, close it, repeat until all new tabs are closed.
    d. Tap Alt a few times to see if the menu bar "sticks".

If I ever saw the menu bar stick, I would consider the issue reproduced. If I went for 10 minutes and it never stuck assume I was on a "good" version.

 - I use the Gmail feature that tells you how many unread emails via the favicon, and it frequently just gets stuck.
