Ive been having a problem for a few months now where whenever I restart firefox, if I had the password manager enabled it would disable itself. I can only assume that an outside program is causing this but I am unable to locate which one. I have uninstalled all password manager applications off of my computer, but am still having this issue. Is there any way I could find what program is causing this to happen?

The Safeway website has always supported Firefox until recently. Now we are told it is incompatible with Firefox and you must use the Chrome browser. Complained to Safeway and they just said they will forward it to their website manager.

Firefox works with all other websites I use.

Looking for any help or advice,

I only use 2 addons in firefox, they are Bitdefender Wallet and Adblock and since the last Firefox update I cannot get either working. I can install adblock, it will work until the browser is closed, next time I open the browser it will be disabled with no option to re enable it and no explanation as to why it was disabled. I have tried a few addons as a test and after the browser is closed all will be automatically disabled. With Bitdefender wallet trying to install the extension results in an error of the download is corrupt.

I have used Firefox for years with both of these options and no errors. To try and fix I have reinstalled both Firefox and Bitdefender but the issue remains the same.

Current Firefox build is at 84.0.2

Any advise would be brilliant as I really do not want to resort to Chrome (which is working perfectly).

Many thanks.

Can anyone tell me, or teach me how to tell, what's happening on the website 'http://www.syscodiscountfoodcenter.com' on the "Products" button? Whenever I click on it, the address bar just becomes 'http://www.syscodiscountfoodcenter.com/#' but nothing happens. I suspect that this is being blocked by some type of security or protection blocker, but I don't know how to determine what.

Ultimately, what I'd like to do is determine exactly what protection is being violated, then turn off this specific protection for just this website, so that I could order products. Can anyone show me a link or page that would describe how to determine what's happening?

Thank you for your help and advice.

My Firefox browser doesn't display photos and run videos when viewing/reading a subject article on websites. Both just show up as a gray, blank screen and there is no audio as well for videos. Nothing. Is there a setting for photos and videos for display on the Firefox browser that I may have missed in my settings search to alleviate these two issues. I believe my Firefox browser is automatically updated, but would want to confirm this. How do I confirm Firefox is up to date and automatically updates? My OS is Windows 10 and it is automatically updated. Help anyone.

Hi guys,

I am experiencing this issue for quite a long time, after certain Windows 10 update Facebook on Firefox becomes really unusable, it is really slow, specially on features when there is typing involved. That means Messenger, commenting posts on Facebook, creating new posts etc. But even other stuff is slow as it is scrolling down, going through photos etc.

This is happening on my both PCs, my CPUs are Ryzen 5 3600, and Intel I7-4770, and GPU GTX 1660S, GTX 1050Ti, so I don`t see that hardware should bottleneck this in any case. In the meantime, I did restart with Safe mode, refreshed Firefox, even reinstalled which does not help. I have tried with other browsers, Facebook works fine there. Currently I am using latest Firefox 84.0.2 64bit on both PCs, and Windows 10 is 20H2 version.

The browser doesn't accept a new internet connection when I switch on/off my company's VPN

Dear Mozilla support,

I have to switch on or off my company's VPN access several times a day, and each time I switch the VPN, the Firefox simply refuses to use a new connection, behaving as there is no internet connection at all, forcing me to reset the browser each time so it could "accommodate to a new network environment". My company gives employees the Cisco AnyConnect SW for establishing the VPN access to the company's infrastructure.

Are you able to "fix" this please, as I haven't experienced this behavior at other browsers as well (Opera, IE)?

In the past, putting a subject in the Firefox search box and choosing the ebay search engine opened ebay and passed the subject to the ebay search. This ebay page automatically came up with the ebay search results.

Not now. Putting a subject in the search box and choosing the ebay search engine opens ebay, but then stops.

My other search engines, Google, Wikepedia, Amazon, work as before and go direct to the search results.

Any advice on how to get the Firefox>ebay>search links to work as before?

Thank you

I've tried refreshing it, reinstalling it, running under a newly created profile, running under safe mode. The crashing continues despite all of these things.

I've had all settings in about:preferences#privacy turned off for years, but a new firewall is asking me to allow default-browser-agent.exe to send data.

I'd have thought the program should stop running altogether when all checkmarks in "Firefox Data Collection and Use" are turned off.

Can I view what data is being sent?
