In an organization of 400+ users, we have deployed firefox ESR, versions 45 and 52, across our users. Most are on 45, but a non trivial amount are on 52. Our users are frequent users of the Java plug in.
For the past month we've been having an issue, that crosses all departments, all environments, all versions, etc. User's will experience a firefox hang, that will *sometimes* work in safe mode, but will always work after after a refresh. To clarify, it will hang on startup every instantiation of firefox until safe mode, where upon normal mode still hangs, or a refresh where normal mode will work. Normally this is not a huge deal, but the issue recurs on the users unpredictably. I have one user who's firefox will hang every other day, requiring IT assistance. Other users, we'll refresh it and it seemingly won't recur, or possibly will after a few days.
We've tried A LOT to combat this issue. Insofar as we can tell, the plugincontainer.exe hangs before firefox.exe does. There's no specific plug in that seems be an issue, as users with identical plug ins will have different experiences. It's affecting about 6% of our users, but a daily occurrence for our help desk. It happens no matter what version of firefox they're on, it happens after a reinstall, etc. We're at our wit's end; firefox has been the best browser for our org, and we don't want to have to switch back to devil IE. But it's looking that way.
