Captive portal detection for public Wi-Fi login fails

I'm using Firefox 102 on Ubuntu Mate 20.04 (the vanilla one from apt), but I think I've experienced the same with a couple of previous versions too ...

So, I've sat in one Espresso House in Denmark; tried to connect to their public Wi-Fi with Firefox in private mode, captive portal went fine, and I was on the Internet. Apparently I had gotten a danish IP address there, since google.com thereafter was in danish.

Now, I sit in a different Espresso House, also in Denmark; however, here, captive portal does not work; in the sense that:

As shown on first screenshot, first I get "You must log in to this network before you can access the Internet.", and I get a "Open network login page" button.

I click on the "Open network login page" button, I can see browser wants to load http://detectportal.firefox.com/canonical.html - but in the end, I do not get the Espresso House login page, but instead I get a redirect to https://support.mozilla.org/en-US/kb/captive-portal , where the "You must log in to this network before you can access the Internet." still stands, but there is no more "Open network login page" button (as shown on the second screenshot)

If I restart the browser in this shop, I think I get the exactly same process - Espresso House wi-fi login page never gets shown, only the https://support.mozilla.org/en-US/kb/captive-portal ...

Strangely, at this point, I do get access to the internet through a browser - but google.com is then in swedish, which I guess means, that there is some sort of a VPN of that shop's wi-fi to Sweden. On the other hand, I don't get internet elsewhere on my computer - for instance, if I want to do `sudo apt update` from the command line, I get errors like "Clearsigned file isn't valid, got 'NOSPLIT' (does the network require authentication?)" - which is what I otherwise get in (the first mentioned) Espresso House, before I've connected to wi-fi via captive portal (once I connect to wi-fi via captive portal there, `sudo apt update` or any other network access from command line is fine).

(Note: my android phone in the same shop, does indeed show Espresso House Wi-Fi login prompt upon Wi-Fi connection, and I can login there fine).

Why does this happen, and how can I force Firefox to show me the actual captive portal so I can login to Wi-Fi - instead of redirecting me to https://support.mozilla.org/en-US/kb/captive-portal ?

Mozilla Firefox keeps crashing, mostly at startup and if I do manage to get it running it crashes after a while. Doesn't respond anymore, and even the crash reporter crashes. I have tried the following things:

Clean up FF Reinstall and refresh (last attempt included deleting the entire Mozilla folder in Program Files) several times Updated Windows Restarted laptop after every reinstall attempt

It won't open in troubleshoot mode.

I am running Windows 10 on a Lenovo Thinkpad 540 laptop.

Additionally, neither Chrome nor Edge will let me access the Mozilla.org website. I downloaded the custom installer on my phone and uploaded it in Mydrive to get in onto my laptop.

Funny detail: I am in Belgium. I was in Ireland for a week last week and it didn't happen once. Got back home and trouble was back.

My husband is having the same issues, by the way.

Any input would be greatly appreciated.

Dual Monitors: Losing the Menu Bar on the second screen while in fullscreen on the first monitor.

Hi All,

I just started running a dual monitor set up on macOS 12.4. I have updated Firefox to version 102.0.1.

I'm running into an issue where if I want to have a video playing from a browser in full screen on one monitor, I lose the menu bar and access to the dock on the other monitor. I have set them up so that they behave as separate spaces but the issue persists. It should be noted that this only occurs when I'm trying to use the web browser on the second monitor. My impression of what's happening is the browser thinks that since it's in full screen on one monitor, it should be on the second screen as well. I want them both to act independently of one another and retain access to the menu bar and dock on the second screen.

I've trialed this with Brave Browser and Safari and neither of them have the same issue which leads me to believe with overwhelming probability that the issue I'm experiencing is isolated to Firefox.

I've included a screenshot from my second monitor. On my primary monitor I have a YouTube video in full screen. I think you can see from the screenshot that the Menu Bar has disappeared from the second display. I also have the Dock set to automatically hide and when the video is full screen on the primary monitor, the Dock will not un-hide itself on the second screen. Unfortunately clicking within the browser will not restore the Menu Bar and access to the Dock. Is this atypical behavior?

I appreciate whatever help you're able to provide.

My installation of 32-bit Firefox 102 had been repeatedly crashing, sometimes for no apparent reason. I decided to download the 64-bit version of Firefox 102, uninstalled the 32-bit version, carried out a standard installed and all this appeared successful. I noticed that I was getting a lot of advertisements and remembered that I had had Ghostery installed as an extension in my 32-bit Firefox. I went to the extensions page, selected Ghostery and asked for it to be added. Shortly after that, I got a message that the installation had been aborted because the extension might be corrupt. I tried again and got the same message. I tried another ad blocker, and got the same message with that one; and tried a third with the same result. What is going on? I haven't changed any settings in Firefox since the standard installation, and the extensions were from the Firefox source, so how can the extensions be corrupt? If it isn't corrupt, why isn't Firefox installing it?

I've been noticing this more and more recently. I'm using Firefox 102.0 on a Mac running Monterey (12.4) with 64GB RAM. Firefox will suddenly zoom up on a screen between 400% up to 800% (I'm guessing; no way to verify this): see screenshot. This happens on random pages without my hitting any keys or clicking on anything, and I cannot replicate it. Note that I do not have screen zoom engaged, nor do I have any sort of zoom mechanism turned on in the OS. Hitting "undo" does nothing, as the browser thinks I'm trying to undo an action on the page, not a zoom. Resetting Firefox or restarting makes no difference.

Note that the screenshot is at actual size, but I have no way to control the resolution at which it shows up for you.

I thought it was my extensions but it was not that. A thread was created on reddit describing the problem I have.

Hi, this is a minor problem and more a quality-of-life thing, as there is no hard crash or bug per se. Context: I need to print a LOT of things every month for the job, so I download a LOT of PDFs.

Problem: When downloading a PDF, if I open it via the dropdown menu in the menubar, it opens, but immediately unfocuses Firefox. That's it. Why the unfocusing? Lol.

Limits: If I mark PDFs to open automatically (in the options) instead of downloading, then it opens fine and no loss of focus. Same thing if I open from a folder, it's set to open in Firefox and it does so, with no loss of focus. As far as I can tell, the issue appears only when opening from the download button/icon/dropdown menu from the menubar.

Suggestion 1) Adding a "Download AND Open in Firefox" option in the settings would be my ultimate greatest option but.... maybe not the best for cluttering millions of people's browser options. It's just what "I" want to do ;)

Suggestion 2) Trace where it loses focus and re-focus / prevent loss of focus when opening from the menu.

Hi everybody, I never cleared my browsing history so far, because I often need to know which websites I already visited when I perform a research on Google. Having the previously visited URLs shown in a different colour is useful for my work.

However, I am wondering whether this huge amount of data could affect the browser speed and memory usage. More specifically, I have a few questions:

1) Out of curiosity, in which file of Firefox installation folder the history is saved, and where can I find it? 2) Do you think it is possible to clear ALL the browsing history, except for one specific URL? 3) Could a cluttered browsing history file affect negatively my browser performance?

Many thanks in advance for your help, Elisa

It's June 2022, and I am using FF64 101.0.1.

My issue is best described by Zaayl (2017) at https://support.mozilla.org/en-US/questions/1157490, but the working and easiest solution I found was the one offered by delclemons (2018) at https://support.mozilla.org/en-US/questions/1229621#question-reply.

My starting page is blank. I have an extension that shows my external IP as a country flag when FF starts up. If the flag doesn't show, I know I still cannot connect to any site. Similar to Zaayl's case, my FF can be able to connect to sites only after a certain amount of time, which varies from instant - very rarely - up to over 10 minutes. The wait always gets longer, especially when FF crashes and have to restart.

I've been searching a long, long time for the right fix. I cringe at the idea that I have to reinstall FF every time there's a major issue, like this one. Syncing back bookmarks and passwords and reinstalling the extensions are the easy part. The painful part is having to set details of accounts in the containers afterwards. I am so glad that is over now. Connection to sites is no longer prolonged after FF startup.

I wanted to thank the persons concerned, but I couldn't reply to their messages, which are now archived. So, I decided to post a new one here to do that; also, to help users who have to same issue as mine.
