Hi, I have firefox on my Ubuntu 23.04. When i start it it shows a black screen. I click quit on my system and then i startup and it lunches normally. What am I doing wrong or how to fix it?

I have a laptop with Ubuntu 22.04. Firefox 307 from deb package works perfect. I wanted to give a try to Flatpak variant 306, which works well too, except two finger gestures back and front won't work. Scroll works. Any scheduled fix for that? Would be cool to move to flatpack completely.

Noticed yesterday but not as prominent, firefox suddenly steals all window focus, trying to do anything in any other window is pushed into firefox no matter if it is minimised or in another workspace. I have tested this in a clean install along with a clean profile. Bitwarden and other windows seem to act weird when they are interacted with.

This all works well and good on b8 and stable. I am using wayland (Ubuntu 22.* default), but xwayland is available.

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 ?

Years ago I imported a Firefox profile from Ubuntu 16.04 to a PC running 18.04. It wasn't very hard. View Hidden Folders, find the old FF profile, copy it. Then go to the 18.04 PC, delete or rename the existing profile, and paste in the profile from the 16.04 rig. Restart the PC, Firefox came up on the 18.04 PC just like it did on the 26.04 PC.

But Ubuntu is doing something different now. Firefox is inside the "snap" folder. Apparently snap is some sort of new package mgr. (?)

I found a firefox profile a few levels down inside the snap folder: Home/snap/firefox/common/.mozilla/firefox/xxxxxxxx.default

Does snap complicate things? Or can I replace the new profile on the 22.04 PC inside the snap folder with the profile that I want to use from the 18.04 PC? Just like in the past, but inside snap rather than the .firefox folder in Home?

Beginning this afternoon, Firefox 107.0 for Mozilla (OS=Ubuntu 22.04) is preventing me from downloading and opening PDF files. i have to use my Win 10 PC to download PDF files.

Hello, I've upgraded my Ubuntu distribution from Ubuntu 20.04 to 22.04 yesterday. This forced me to update my Firefox version, I am now running the 104.0.2. I now have the following issue: on some websites, the page loads normally but as soon as it's loaded, the page becomes entirely blank. This doesn't seem to be a website issue, as it actually appears normal for a very short instant before it disappears. A website for which this happens is: https://www.lalibre.be/ (I only encountered the issue on another website but it's from the same editor). I tried in a private window and it works normally! I tried in the normal window after deactivating all the addons, it still doesn't work. I tried with or without the Firefox account logged in, it doesn't work. Until now, it's only these 2 websites from the same editor, but as I said, they worked fine yesterday, they work fine on other browsers and they work fine in Firefox private mode. Any idea where this might come from?

Hey guys, I'm using Ubuntu 24.04 with Firefox 124.0 .deb release from this repository: https://launchpad.net/%7Emozillateam/+archive/ubuntu/ppa I enabled "Ask whether to open or save files" from settings. Whenever the Open/Save dialogue is shown and I choose Open, I expect that the file would be opened using the default application. But Firefox asks again to choose the application by which the file (file link?) should be opened. It seems that Firefox is somehow change the way the files are opened through external applications and transformed local file addresses to file://uri/on/disk.

I downloaded Thunderbird 115 into Downloads/ directory Ubuntu 22.04 LTS and extracted the bz2 file. I did a cd to thunderbird and ran ./configure. Error the file was not found. What am I missing?

The tool tip colour for the Downloads is white text over a yellow background - it's practically impossible to read. Perhaps this is an error with the release, but if not, can this extreme lack of textual contrast be changed? I need dark / black text on light backgrounds.

Hello dear firefox developpers.

Recently i realized firefox is not saving cache where it used to. that happens some versions ago to now.

By a sudden necessity, i need to access images stored in cache by facebook.

however, firefox has moved its cache, and have no idea where it stores it now.

the second point, is, if there is any way of "surf" cache, im not sure but i wonder, the cache is not what used to be, a collection of files related to what you surfed in the web, videos, htmls, pictures, etc.

I seems the cache now works in a different way, making solid archives composed of many images-videos..., instead of separate files for every image-video.

So, in a brief, 2 things:

- where is cache now - how can i access files in it, (images videos ..)

PD:im using ubuntu 20.04 PD2:have a nice day, and thanks. PD3: trolls will be attended in office hours

Hi,

I'm trying to access locally-installed help files that are in /usr/share. When I try accessing anything starting with "file:///usr" in Firefox, I get "Access to the file was denied".

I've already set "security.fileuri.strict_origin_policy = false", which now let me access "file:///tmp", "file:///media" and "file:///home", but anything under "file:///usr" (and serveral other top-level directories) still returns the access denied error.

I'm running Firefox 102.0.1 (64-bit) on Ubuntu 22.04.1 LTS.

Zorin16-Linux version 99.0 Ubuntu Canonical 1.0, -found in Help/About. Firefox recognition of version below says 91.0. Also have Linux Mint 19.3 (Tricia). Computer 15YO Dell Dimension 900.

I've had no problems with Linux Firefox for many years. I do not use any other Non-Linux OSes. Linux Mint updates Firefox regularly and so do I in that OS. I'm currently in a free version of Zorin which doesn't seem to push out updates, so my Zorin Firefox may be sadly out of date.

At any rate, today in Zorin, when I went to several of the bigger online sales platforms, they refused to accept my Firefox and suggested Chrome, Opera, and Safari; Target suggested Firefox.

Went to Mozilla to try and upgrade, but it didn't offer the Linux browser automatically when it read my computer. I was only offered the Windows browser. This may be because the computer is an old Dell Windows machine that I converted to Linux or it may not. I've never had this happen before.

Yesterday in Linux Mint, in which Firefox is upgraded at least weekly, the same thing happened once with a big online retailer. They said my browser was outdated and unsafe.

What's going on? I'm wondering if Linux OSes are simply not being accepted when the big retailers are doing software upgrades, or is something going on with Firefox?

Using either the SNAP or .deb versions of Firefox on Ubuntu 22.04 I am running into issues attaching files on remote systems. I can browse to mounted network drives and select files but when clicking open nothing is attached in any of my online email accounts. This also applies to the open dialog box. I have tried using the KDE File Picker as well as the GTK one but they both fail. This is not an issue for LibreOffice or other programs and greatly impacts the usefulness of Firefox.

Clicking the back button does not usually take me back to Google search results. When I do a Google search and click on one of the resulting links, it's often (but not always, oddly enough) as if I've opened the link in a new tab with no browsing history. I can continue to click on links and build the tab's history, but the oldest url in the tab history is the one I got to after the Google search results page. To get to the Google page, I have to open my full browsing history.

If it's just my problem, I'll just keep doing that, but I appreciate any ideas. Maybe it's how Google redirects? Is there a setting that could affect this? Some of my settings are inherited from Ubuntu Studio.

Thanks.

I am running Unix Ubuntu 22.04 with Firefox 104.0.01 (64 bit). My Canon LBP 6230DW works fine in my word processor and in Chrome, but it does not show up in the Printer destination field when I am in Firefox. The only print option is to "Save as PDF." How do I get the Canon to be a print destination in Firefox?

This is my second request because I can't find my original question. jonzn4SUSE has asked me to upload print screens, which are attached. Carl ([email removed from public])
