Not every potentially site-breaking addon has a site whitelist or enable/disable list. While some addons exsit for "sandboxing" tabs - it only sandboxes the pages loaded on that tab, not what the browser/addons do to them. I've already searched for solutions, and frankly, I'm surprised that this question hasn't been asked before until now: Why can't multiple "profiles" be run side-by-side, on a per-tab and/or specific-website(s) basis, in the same browser window?

With the latest update access to all Cisco devices via FireFox is no longer supported. I am now receiving the following errors:

Secure Connection Failed An error occurred during a connection to [IP]. SSL received a weak ephemeral Diffie-Hellman key in Server Key Exchange handshake message. (Error code: ssl_error_weak_server_ephemeral_dh_key) The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the website owners to inform them of this problem.

Is there a way to roll-back the version to avoid this or a permanent fix? FireFox is currently the only browser that works very well with Cisco devices and now it will not work at all.

Hello, I have recently noticed that despite the Firefox process being closed, there are a number of connections still open and remain open for the duration of the current computer session. Restart seems to close all connections. Connections increase and stay open the more I would browse.

OS is Windows 7 Ultimate Running Firefox 55.0.3 Using Kaspersky Internet Security 2018 to monitor active connections.

Screen shot attached to show some examples of active connections even when Firefox is closed. Any idea why this is happening and how to prevent it?

For past several days, a pop-up message appears every time I attempt to open my browser asking if I want to allow this app to make changes to my computer. The app is listed as Firefox Software Updater. When I checked Add-ons, I notice an add-on which is listed as temporary in support of Safe Browsing Version 4 and will supposedly be deleted once the roll-out of this feature is complete. How long is this 'roll-out' supposed to take? This has been going on for days. Should I be responding 'No' or 'Yes'? I'm using Windows 10 and Firefox 56.0.1.

Hi guys, I'm working on locking down Firefox for some of our corporate machines, and in at least one of our configurations, I need to completely remove access to the Library and all it's components for security reasons, as it could be abused to browse local drives, and these are supposed to be kiosks.

Is there a way to either disable the UI element of the Library (what's the CSS ID, and then I can try to put it in CCK2 to disable that UI element) or to completely disable the Library window/functions/feature itself?

As an administrator in a small office, i am using trend micro add on as a web filtering. But all of my web filtering rules will gone if the add on is disabled by my fellow officer in their PC. And i can't find any settings to lock it down.

I ask for this features because firefox is my favorite browser, and i want to keep using firefox. I Tried google chrome, and for now i cannot find how to disable my trendmicro web filtering on chrome (which is a good thing) Internet Explorer just not an option, it's too obsolete.

If firefox not updating this features in the near future, i will need to use chrome in order to patch my office security. Please update as soon as possible.

I was attempting to restore my tabs and as it wasn't working properly, I was editing a sessionstore.js or recovery.js looking for URLs that were present so I could re-open the tabs to recreate what I had before.

To my horror, on one of the tab details I find stored in the sessionstore/recovery, all the details from a purchase page I had filled in to buy a tour, had not only my name and address, but telephone number, and address. That would be bad enough, but also stored was the complete details of my credit card which I had used for the purchase. That included the name on the credit card, expiry date, and security code. It probably also had the card number, but I had been doing some editing so may have accidentally deleted it before I noticed what was in there.

How is this a regard by Mozilla for my privacy and security? When will this be rectified? I hope soon, as this sort of information should not be left around/stored on a computer following it's use.

I am not going to share the file details with you for obvious reasons, so I am not sure if the attached information will be any use to you.

Received an email from Mozilla (rightly) thrashing Facebook for privacy and security breaches.

The issue is that my Firefox sign-on password is used as my first name in the email.

ie Dear <then my password>,

it is difficult to think of a more serious breach than this, and there is now way to directly report the problem to them - hope they look at this post.

I have checked all my account setting and belive these are correct

These personalized newsfeeds, whatever they are-- Google does them all. Some are not as intrusive as others. But within Firefox, I get some of the most bizarre news stories... stories about things I'm not even talking to other people about or looking up online. How could it possibly find a connection? Even when there is a minute connection. It's not a coincidence. It's like, is my phone hacked-- are people reading my mind? It's some form of breach of privacy.

Granted, all the accounts I use are logged into Firefox. Tonight, I took a gander over the privacy settings, and as usual my jaw dropped in disbelief. Permissions; Locations, Camera, etc.-- instead of valuing peoples' privacy and not caring one ioda like Fuckfacebook, many privacy-invading functions are ON by default until they are turned off by the user. This is why I don't use apps. It's why I quit Facebook many years ago. And now, I say goodbye to Firebox. Sick and tired of people encroaching on my privacy. It's principal, nothing more, nothing less-- THIS BROWSER IS GONE. Stay out of my personal business.

Probable 'deadly embrace' memory allocation issue between Firefox and Microsoft Update

I had my usual "several" (probably 3 to 5) Firefox windows/tabs open ... and Microsoft decided to send an update to my Windows 7 box.

I observed Firefox memory use rise rapidly to nearly 800MB ... while netsvcs.exe did approximately the same thing. (This machine has 2GB of RAM.)

Fortunately I had Windows Performance Monitor running, and was able to determine that Windows Update was the competing activity ... and after-the-fact, determined that it had been installing an update to MS Security Essentials (basically a malware signature update - and I have the ID of the specific update, but since it is a security update, I'm hesitant to post that detail in a quasi-public forum). Usually, such updates install quickly and transparently. I also cannot tell, with confidence, whether the memory consumption was from the process of installing the signature - or the process of scanning for malware presence after the sig was installed (although I'd *guess* the latter). I believe both of those aspects execute within netsvcs.exe.

This happened over a period of approximately an hour, during which about all I could do was "sniff around" to identify the culprits; eventually I killed the Firefox process (hoping that its History feature would allow me to return to my open tabs... which was not quite true).

I have reported the event to Microsoft as well, as it could equally be their problem.

Suggestion: Add instrumentation to Firefox to capture data on sudden increases in RAM use - paying particular attention to outside-the-norm values, in relatively short time periods (minutes, not hours) that do not self-resolve ... and consider whether Firefox can be more aggressive at releasing memory it has "claimed," when things go bad.

(Perhaps collect high-level "physical memory available" data when things begin to "go bad," and capture the "footprint" of Firefox memory use... And perhaps add intelligence to log memory allocation failures somewhere. I don't know with certainty if the issue was fragmentation, or the sheer amount requested, but experience and grey-hair lead me to suspect the former. The only Firefox window/tab that I know might have been a high-memory-consumer was a moderate-sized Google Map covering an urban area of several dozen square miles, so it was a complex image.)

Not suggesting this is Firefox's "fault" -- clearly, both processes were "to blame" in the sense that they didn't handle the situation well... but Firefox might handle it better.

I've seen (and reported) quite a series of memory-utilization issues since 28.0 ... perhaps it's time for a "tiger team" to look into these.

AH - one other detail: I keep Firefox pinned to the Windows task bar, and when it starts, it asks me which profile I want to use (of about 5 choices). When restarting Firefox after identifying all the above... I found that it no longer asked me to choose a profile, and the profile it opened was clearly NOT my most-common profile, which includes (e.g.) all my most-common, site-specific login information. I had to mess around for several minutes to get this profile "back" up and running, and I did not make note of what I tried during that effort.

There seems to be a resource usage conflict between Firefox and Norton Security (and sometimes other programs). Response time is OK for a while, then suddenly goes down to the point I have to terminate Firefox with the Task Manager (Norton can't be terminated). After termination, I can wait a few seconds for the performance graphs to go to minimum, then restart Firefox and it will be OK again for a while, then the above situation will repeat. One odd thing is that even when response is OK, Task Manager shows Firefox (and plugin-container.exe) doing continuous disk I/Os, even though I'm not doing anything to cause excessive activity, like just looking at text on a page. This doesn't seem normal to me. I'm running with Windows XP 5.1 SP3.

At some point I disabled trust for this cert (along with many others - I distrust non-English CAs and those known to have been hacked). Then when I clicked "Get Add ons" I would get a failure connecting to services.addons.mozilla.org due to untrusted issuer. There is no option to "add exception" because the site uses HSTS, according to the msg.

Outside of Firefox i had to use my own code to connect to services.addons.mozilla.org and debug the SSL/TLS handshake. I saw the root CA from the server and checked my Firefox trust store. Once I re-enabled trust for the DigiCert Global Root CA, I could successfully execute "Get Add ons".

The point here is that you error screen is not helpful. Even if you do not want to let me add an exception, you should at least give me a clear option to view the cert chain. Otherwise how else can someone possibly fix this? Luckily I work with security stuff so could find the certs in the chain externally by other means.

Thank you.
