After update to firefox 80 sometimes random pages do not load. They open as blank white page with refresh button being inactive. Only way to solve this problem is close page, open new tab and try to load this page again.

This is completely random, happening on all sites, opened from links on other sites, bookmarks or speed dial. No idea what could cause it. Maybe firefox has some problems with creating new process for new tab if my process limit is set to 1?

I am running Mojave (10.14.6) on my Mac desktop. My computer automatically downloaded and updated my Firefox browser to 81.0. I can no longer access sites like Yahoo, Twitter, and Pinterest. When I attempt to go to them, the browser simply ignores the request and stays on the current page. Has some setting changed with the new browser? If so, how do I fix this? If I can't access these sites, the browser is effectively useless.

For ever each time I selected typed text in the search bar and clicked on a search engine the results would open in a new tab. No it does not and the only thing I did was to install Chrome because a web site was not displaying properly. The site is my.Mintmobile.com login in and select referral tab and a blank space appears where there should be information on inputting a email address and a link to send. Works in chrome but not in Firefox current 81. 64 bit.

There is a certain website that I have to visit often. I usually type the first few letters of the URL into search bar but, annoyingly, there's another website with almost exactly the same URL. Firefox always autofills the wrong URL and I always end up getting directed to the wrong site. Is there a way to prevent firefox from autofilling that URL and change it to the correct one?

Hi, PDF File handling has recently changed - For the worse for me and it's become really frustrating.

When I right click a PDF file link and select "open link in new tab", why does Firefox then ask me how I want to treat the file? I just asked it to open the file in a new tab, so it should be obvious what I want to do - asking again is illogical.

Not only that, before the file handling dialog box, it opens a new tab next to the tab I'm in and then closes it when the dialog box appears - When I select the unnecessary "open in Firefox" (I just asked it to open in a new tab), it now creates a new tab at the END of my tabs and steals focus.

I also get the file handling dialog box when I ask to "save link as", when logically I should just get the save location dialog box.

How do I get the old behaviour back?

Thanks folks

FireFox Networking guidance on routing and network interface selection

Hi all,

I am working on a study project around mitigation strategies to protect against man in the middle attacks and would like some advice around how FireFox deals with detecting a new network adapter and an update of routes on the local host whilst FireFox is running.

My study project involves connecting a small (malicious) device that configures ethernet over USB, this device also runs a web server, a DHCP server and a DNS server to essentially perform a man in the middle attack. When the device is connected a DHCP address is issued to the ethernet over USB device and the subnet mask on the victim is set to route all ipv4 addresses to the malicious device, the device also spoofs all DNS queries on the fly to route to the device this ensures that all traffic is routed to the device.

This ultimately provides a method for any HTTP request from the browser to hit the device, the device responds with html content containing a malicious script. Many websites frequently make HTTP requests without intervention, such as an advert, and so this attack can run automatically.

For my testing I have used a range of browsers and in each scenario I open 2 tabs, one standard http page and another http page that has an auto refresh capability built in via refresh javascript to refresh the page every 60 seconds. I set up the two tabs and leave them open, then plug in my device. In the case of Internet explorer, Chrome, Edge and Safari the man in the middle attack works automatically without any issues. But for FireFox it does not, the web page continues to refresh as normal even though the local OS thinks that the device is where the website resides. I can confirm this by using ping, looking at local routes and running wireshark, in the case of Firefox even after connecting the device I can see all HTTP requests still run over the wireless interface. I check FireFox developer and also disable cache. Yet in all other browsers the http request runs over the device I connect and all http traffic ceases to run over the wireless interface. If I manually refresh the page or open a new http page in FireFox the traffic routes to the device. If I set Firefox to offline and then online whilst leaving the auto refresh page open the HTTP request will route over the device, so this to me seems like some sort of caching.

I have tested this on 2 x Macbooks and Windows 7 (testing only :-)) and Windows 10 and have the same result.

To try and resolve I have turned off DNS prefetch and also looked at the network settings and changed each proxy option, currently I have it set to no proxy. I also searched for similar articles and read this article, which is seemingly relevant but did not solve my specific use case. https://daniel.haxx.se/blog/2014/09/26/changing-networks-with-firefox-running/

I am not interested in a fix, but I am interested to understand why this happens and if this is actually a specific feature within FireFox and any other useful information around this specific scenario.

Thanks a lot for reading

Hi. I've been using Multi Account Containers for a few months. Also the Facebook container and First Party Isolation.

I have a couple of problems:

1. It seems to be impossible to "stay logged in" to different sites. For example, I have a container for Apple iCloud. But I still have to log in every time including the two factor phone authentication and indicating I trust the browser. Why is that?

2. Even when I invoke, "Reopen in no container" there still seems to be a container. Ideally, I'd like to be able to indicate to never use a container for iCloud for example.

3. Containers seem to break paying with PayPal for some sites. Or it could be the First Party Isolation stopping the sharing of information.

I do like using containers for sites like Google but ultimately, they may be more trouble than they're worth.

I have a website which makes ajax requests to some endpoints which can take more than a minute (depending on how busy the server might be). In the recent version of firefox (81), it seems like after about a minute, the request appears to time out without an error message. I checked against other browsers and none seem to have the same issue.

Was this behavior expected out of version 81? I don't see anything in the release notes about this kind of change.

Hi, Firefox used to have a nice dark-gray background behind the actual pdf in the pdf viewer. Since the latest update, it's now a bright white, which is a non-starter for working in the evening.

How can I revert to the old pdf viewer (or at least emulate the background color) without reverting my firefox version? Thanks!

I started to download some files from a public web site and noticed, after downloading a few files, that the next few downloads all refused to actually start, showing unknown time left. To clarify, a few downloads would work fine, but then I would attempt the next download and it would cause the download to hang. Worse, I cannot download any files - at all - beyond that until I close my browser and reopen it.

This has happened ive times in ten minutes. Every time, restarting the browser causes the files I attempted to download previously to immediately successfully download without any intervention from myself upon relaunch. I can then download another few files, and then it starts to hang again. I have been forced to move this downloading activity over to Google Chrome while reporting the issue, and so far Chrome does not seem to have any issues.

Any ideas?

How to Undo Firefox: "Remember this Decision" for Digital Certificate

Hi, I'm trying to access a Spanish government website which requires me to have a certain digital certificate imported into my computer in order to identify myself. However I made a mistake and don't know how to reverse it:

To explain what happened, when I went to the website sede.administracionespublicas.gob.es/infoext2 to check on the status of a Spanish document, and clicked on the "consultar con cl@ve" button (cl@ve is the Spanish government's user authentication system), I was prompted with a window that asked me which digital certificate I wanted to use for the website. ('m attaching a picture of the prompt to this post)

Unfortunately, I accidentally hit the cancel button, with the checkbox checked saying "recordar esta decision" ("remember this decision" in English) , so now every time I go to this website, it doesn't let me present the digital certificate, it just says there's a user identification error with cl@ve (I think it's "remembering" to automatically cancel my ability to present a certificate every time I go to the website time now).

Do you know how to undo the "recordar esta decisión" ("remember this decision" in English) checkbox so that I can make the decision again and choose to present my certificate? I tried clearing my browsing data from the previous 2 hours but it didn't seem to help.

Let me know what you think and thank you in advance.

Also, the version of the browser this happened on was Firefox 68.12, as the Spanish government insists that only old browsers will support their authentication system.
