Hi everyone, We've been experiencing an increase in reports of issues with Firefox lately and I'm wondering if I'm not alone.
I'm getting reports (randomly) for these issues: -_Firefox freezes_ with spinning mouse wheel indicator. Program goes not responding for a few seconds, and then resumes. Restarting Firefox generally clears this condition, but it will re-occur after several hours of uptime and seems to be related to the number of tabs open: the more tabs, the quicker this issue occurs. -_Websites loading extremely slow_: Firefox will show "loading" indicator for many second/minutes. Sites almost always eventually load, but we see load times measures in minutes, not < 5 seconds. This happens to internally-hosted sites (Intranet) as well, not just Internet sites. On the same computer Internet Explorer will load the same sites quickly, without delay (including the Intranet sites). The frequency of this seems to decrease if we clear Firefox's on-disk cache. We're testing disabling on-disk cache globally, but are still getting these reports with on-disk cache disabled & cleared. -_Firefox crashes_ resulting in crash reporter launching. For the past ~2 weeks I'm getting a flood of these reports. The crash reports always match this: https://crash-stats.mozilla.com/signature/?product=Firefox&signature=shutdownhang%20%7C%20nsThread%3A%3AShutdown%20%7C%20nsUrlClassifierDBService%3A%3AShutdown&date=%3E%3D2017-11-24T10%3A10%3A10.000Z&date=%3C2017-12-01T10%3A10%3A10.000Z#summary I see https://bugzilla.mozilla.org/show_bug.cgi?id=1408631 discussed the same crash signature being uplifted to ESR, but was not possible due to some changes in the newer code? The crash-stats Reports/Graphs seem to indicate that I'm not the only one experiencing this type of crashing in the past few weeks. To compare config/environment notes we use: -Latest Firefox ESR (52.5.0) (99% 32-bit, but a few use 64-bit Firefox) -Redirected user profiles to network shares (99% have this, but the remaining 1% that have locally-stored profiles also experience some/all the above issues). -CCK2 for configuration/settings -Win 7 SP1 - all latest updates -Latest Flash Player plugin (27.0.0.187) I've been racking my brain trying to figure out if any of this is environmental/configuration related or if some/all are bugs in Firefox. Is anyone else experiencing increased or similar issues with recent Firefox ESR builds? Have you done anything that helps/corrects any of these issues? Thanks for any feedback, Joel
