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 ?

My OS is Pop! OS. Using 'Tidal' as a web based music streaming service and I play vids on YouTube. Every time a new song or video starts, or when I skip, rewind or do anything like that, it auto resets the volume level output in my sound settings to about 75 to 80 % of the max possible level. So basically, I have to adjust each and every new song by hand, it is infuriating. I block facebooknet in Umatrix and firebaseinstallation googleapis as well as google tag manager but nothing else. That's on Tidal, similarly I do not block essential cookies on YouTube, so I don't think that is the problem. I have a hunch that the answer is somewhere in about:config. If this is intentional, then I'm giving up hope. Thank you.

Specifically within the Firefox browser, I cannot access Reddit.com or other affiliate links. I am just getting a completely white screen, doesn't even say "Blocked". However I can visit Reddit in other browsers, with or without a VPN, while a VPN doesn't even change the outcome within the Firefox browser.

Any help would be much appreciated, thank you.

Hi, I use Verizon Fios and a Windows 10 PC. Firefox is my default browser. I don't experience any of the problems described below when using Chrome, which I only do now that Firefox is not working optimally.

In many, many years I've never had trouble with Firefox until about a month ago. When I opened the browser, I received messages -- about five times -- that it had crashed. After that, many websites now load very slowly, or not at all. And now, I'm unable to see product images on Amazon.

Would you please help me? I'm 84 and not all that computer savvy and I don't want to delete my browsing history, etc. Many thanks, Valerie

Hey there,

I use Adobe Acrobat Pro to open PDFs for work. It always worked fine, set up to automatically open PDFs in Adobe, and they save to Downloads folder. For some reason now, after an update, the PDF always pulls up a save box and asks me to name the file (significantly slows down workflow). This only happened after an update.

I've figured out that the issue is related to a way that the PDFs are generated. So if I click it via a link that ends in .html instead of .pdf, it assumes it's a webpage and opens the pdf link in browser, and from there I have to click save, and then I'm prompted to type in the file name.

If I open a PDF link that's an actual .pdf file URL, then it saves to Downloads automatically and names the file "contractfile-1111" or whatever, numbered consecutively. Any ideas on how to get around this?

Thanks

Hi all, I'm having a lot of problems with Firefox crashing pretty often. Sometimes once or twice a day.

I most often see crashes in the middle of a Webex video conference for work. But Firefox sometimes goes down in other situations that I see no pattern in.

This is Ubuntu 20.04, Firefox 102.0. Unfortunately, it's a complex environment to debug.

First, when firefox goes down, it rarely leaves a crash report behind. So I'm not getting any direct evidence as to what is happening. Second, I run with uBlock active and it is very difficult to function in the browser without long enough for the crash to happen. Third, I typically have several hundred tabs open. I have a lot of memory (64G) in my machine, and the machine doesn't act like it's swapping, so I don't think I'm running out of memory.

Any help getting to the bottom of what's going on is welcome.

  2. 2 Other browsers open PDFs correctly.

I have done the steps in here : https://support.mozilla.org/en-US/kb/error-codes-secure-websites I don't have any third-party Antivirus

I have also do about:config security.enterprise_roots.enabled by changing to true. It works but unfortunately youtube is broken when i set it to true.

I can't also accept the risk and continue since there's no button that says it.

Whenever I try to open a pdf file (automatically opened in Acrobat), Firefox hangs a long time, before eventually opening it in Acrobat.

When I open the download dialog, it always shows the file is almost downloaded, but the progress bar always hangs near the end. When I go to the download folder, I always see the pdf I'm trying to open with a filesize of 0kb. This behaviour is the same for large and small files. Eventually (after several minutes), it just opens as it should.

I already tried reinstalling Acrobat.

The behaviour is the same in regular Firefox (102.0 64-bit win7) and Firefox developer (103.0b4 64-bit win7).

It is specifically with pdf files. Other downloaded documents seem to open as it should.

Can someone help me to trace and solve the cause of this issue?

Recently got a new computer with Windows 11, and now whenever I try to play a Youtube video or videos on other sites, Firefox as a whole slows down. There is a delay when starting the video, and at times Firefox stops responding if I try to switch to another tab when this is happening. (Not always, but sometimes).

The delay can be anywhere from 5 to 45 seconds or so, and repeats whenever I pause and unpause a video, or even rewind slightly. This doesn't seem to be buffering, and videos seem to work just fine on Edge. Any idea what could be causing this issue?

Firefox was working fine yesterday. But all of a sudden while playing a youtube video it started being choppy. It drops frames, scrolling and video playback are choppy and laggy, there is lag on button inputs, the system is choppy and laggy too while firefox is open, especially when video is playing. I checked the CPU and GPU usage and I can't see any spikes. I have tried refreshing firefox but that did not fix the problem.

OS is manjaro linux (gnome version) latest. Firefox is also at the latest version.

Immediately following a Firefox update I began having scrolling problems on my Facebook page. I am able to scroll down normally to a point, and then, all of a sudden, the scroll bar will go up and immediately go back down without me touching the mouse. It will continue doing the up and down scrolling indefinitely and at a high rate of speed. I have tried turning off auto scroll and smooth scrolling at the browser, but no luck. I have Windows 8.1. I have never heard of anyone else having this problem so this seemed like my only option.

How do I keep Firefox from losing the internet connection just cause I don't want to close all the tabs I've had open the past week or so? I've tried clearing the cookies, and then reloading my open tabs, but it ends up losing the connection, just the browser itself. Other browser still works. Completely closing all tabs and restarting Firefox gets it working again, but dare I reload the previous session again, open all the tabs (acts like it's going to work), but then loses connection.
