We use Firefox fairly extensively in our VDI environment and has become our organization's standard web browser. In a non-persistent VDI environment, on occasion we have users that experience the dreaded "Couldn't load XPCOM" popup error message. In my research this usually is attributed to a faulty/corrupt update. We are a VMware View shop using instant clones with what's called a "Writable Volume" which is, in essence, a file system filter that allows certain user data to be written to persistent storage and the rest is written to the non-persistent VM. Upon logout the persistent disk is detached and the non-persistent VM is removed/rebuilt.
We are using the ESR branch of Firefox with policies configured to disable automatic updating, so I'm not sure where Firefox is breaking. Is there anything I can do to assist? On top of this, it's more difficult to reproduce since I'm unable to causing it to error out myself.

Hello,
I'm using version 60.7.2esr in an enterprise context behind a proxy.
And I have the following issue : after some time using firefox, https://www.google.com becomes unreachable.
But this website is available from edge or chrome. All these other browsers are using the same enterprise proxy with the same configuration.
I checked the network tab : there is no even a header sent apparently, hinting there is an issue before even getting to send a header.
Hence I imagined it could be a firefox DNS cache issue.
I deactivated it by modifying the user.js as I cannot modify it in about:preferences user_pref("network.dns.disablePrefetch","true") user_pref("network.dnsCacheExpiration",0)
But that didn't change the issue.
Do you have any suggestion on how to find what is going on? or a possible culprit?
Since Firefox 67.0.1, Google and some other websites can't be access if a proxy is performing HTTPS decryption

Firefox is showing this error : SEC_ERROR_REUSED_ISSUER_AND_SERIAL
The proxy is performing https decryption based on a crafted rootCA that is distributed through GPO (Windows AD environment.) and firerefox configured to trust enterprise roots CAs (security.enterprise_roots.enabled;true) All worked fine before Firefox 67.0.1 Now, some websites are still working but some are not, including Google and Mozilla's sites. Chrome is working fine with both of those websites. Proxy used is Trendicro Interscan Web security virtual appliance 6.5 sp2 fully patched.

On our non-persistent VDI environment we experiencing users where FireFox crashes frequently - We're running W7 Enterprise 32bits - Firefox version 60.6.1ESR 32 bits
i was expecting Sophos to causing this issue, so i created a new VDI machine without Sophos installed. The same issue appered.
I can reproduce the issue when launching a radio station on http://www.onlineluisteren.nl/ Issue appears between the 5 minutes and 2 hours
Worknotes: - Launched firefox in safe mode - Turned off hardware acceleration - created a new VDI image without our anti-virus 'Sophos' - issue was also happening with Firefox 60.5.2ESR

Windows 7 32-bit Enterprise running in a VMware workstation pro VM. Firefox has been working fine until I told it to go ahead and update last week. Since the update firefox fails to start. I see the window border form and then disappear. No crash logs in Firefox crash dir. Uninstalled and re-installed (specifically chose 32-bit installer) and told it to reset everything (clean install). Still have problem. I do find this in event log. Images are also attached. The .dll mentioned has a different name every time and all virus/malware scans show clean both for the firefox installer and the system.

I used firefox to upload a 7z file into a website. Some time later I was reported the 7z file was returning CRC errors when decompressing. After downloading it from the website and comparing it against the original 7z (raw byte comparison) file I discovered a large section of the file, near the bottom, was replaced.
However the worst part is not that the file was corrupted but that the data inserted on the file contains user information. On thie section I found several strings matching all sorts of things:
- URLs I have recently visited
- Search bar history (searches I have recently done on google)
- Login details saved on my firefox
- part of pages I have recently visited
Is this a known issue? This is a big deal for me and I will stop using firefox until this is fixed.
I am using 60.0.1 (64-bit) over win8.1.

After installation of a web proxy/security agent - Cyren Web Security - at our organization, users are getting a misbehaviour of firefox.
Upon opening, the message "Safe Mode is a special mode of Firefox ..." appears and the buttons "Start in Safe Mode" and "Refresh Firefox" appears.
Choosing any of the above options results in the following: Firefox opens. Disappears momentarily after a few seconds. Re-opens, saying all the tabs have crashed. Disappears again momentarily after a few seconds. Re-opens, saying all the tabs have crashed. Goes on in a loop
Trying to kill the process from Task Manager. Firefox appears again, new process respawns and goes in the loop above. Operation (Task kill) must either be repeated a number of times (approx 10) or workstation restart so that firefox goes off.
We have sadly had to resort to Google Chrome in the meantime the issue is under investigation.
Affected versions vary from 52 to 60.01 (latest)
I have tried to deploy Firefox ESR 52.8.0 to resolve the matter. This resolved the matter for some users. For others, issue persists on Firefox ESR as well.
PLease help.
