I run wxmaxima on ubunbtu 20.04. The help menu option calls up firefox (v 101.0.1 (64 bit)) to find the local on disk html files. However this brings up the error message:

File not found

Firefox can’t find the file at /usr/share/maxima/5.45.1/doc/html/maxima_singlepage.html#g_t_0025.

But this is a valid path with user access permissions and the file maxima_singlepage.html exists and has user read permissions.

So what is firefox doing in looking for this file?

I have used the ms windows 10 version of wxmaxima and the firefox help works perfectly.

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.

Normally when I am not using Firefox My cursor is different (I have changed it in settings). Yet when I use Firefox It changes to Ubuntu's Default cursor. I don't know what type of information is required but I will happily provide them if you tell me about them.

In the Flatpak version of Firefox 103.0.2 the resize handles do not appear when you hover over any of the 4 edges of the firefox window unless you hold down the left mouse button, then they appear, but you have to get the mouse pointer just right before pressing the left mouse button. I notice on several forums that this has been like this for the last 2 months, are the team at Mozilla working on a fix, cheers

A certain website (flixbus.com) is getting pinned on my firefox automatically. I have unpinned it several times but after few seconds, it gets pinned again. It's driving me nuts. I even cleared all my cookies but it didn't help.

Firefox will no longer display the main window. I get an icon in my taskbar but the window is nowhere to be found. I've tried the tricks of maximizing it and moving it but neither works. I have found that if I locate the xulstore.json file it will work but only for a short time. Next time I start Firefox I get an icon but no window. Very frustrating!

The sulstore.json file contains nothing that suspicious:

``` {"chrome://browser/content/browser.xhtml":{"main-window":{"screenX":"2129","screenY":"777","width":"1280","height":"1040","sizemode":"maximized"},"sidebar-box":{"sidebarcommand":"","style":""},"sidebar-title":{"value":""}}} ```

If I start Firefox and right-click the icon, select maximize it's as if it's maximized covering all my windows but yet invisible. I can see my other windows but I cannot interact with them.

Deleting the xulstore.json file often fixes this but it breaks again shortly. What's the deal???

Firefox browser crashes whenever uploading or downloading is tried. It seems website independent, and even a trial to start download from an email crashes the browser. Report IDs for some of the submitted crash reports:

Hello, I'm on Ubuntu 22.04 and have the Firefox (107.0 64bit) installed as a snap.

The drag and selecting text and even dragging objects on any websites doesn't work.

• I select text on the website by pressing down and starting to drag the text doesn't select when I leave the hold the entire block gets highlighted
• I use Excalidraw, the pencil tool drag and any object size change while drag doesn't work
• Desmos I can't drag the points on the graph
• The pointer just disappears on videos (not just YouTube) and isn't visible until I pause the video

I am using Mozilla Firefox, ver. 102.0.1, 46 bit, snap for Ubuntu 22.04. I have two issues with saving files in Mozilla.

First, when I try to save a pdf using the CTRL+S key, it open multiple (~100) instances of save dialogue box. Initially I thought my computer got freezed, since pressing the save key didn't had any effect. I tried to move it using the CTRL+SPACE key -> Move option, and then I realized there are many such save dialogue box are open. How to rectify its behavior?

Second, it downloads the file only in system created folder (e.g. ~\Download, ~\Document, ~\Pictures, etc) and not other user created folders (e.g ~\Dropbox, etc.). The dialogue box for saving file closes without giving any warning/error message. When I check the file it is not downloaded (in user created folders). Can there be any permission issue?

I have already reinstalled the Mozilla once!

I upgraded my OS yesterday to Ubuntu 22.04.1 LTS. That upgrade included the newest Firefox, 103.0.2. Most of the websites I go to load just fine but some; Facebook, Nextdoor, Inkscape chat, do not load. The page will start to load and then just hang. What to do, what to do.

I am running a fresh instaled Ubuntu 2022.04, so this is the first Firefox-from-snap.

I am a Jupyter user, and when launch the Jupyter-lab (which try read a file in ~/.local/... directory) I get the deny; I can launch it when connect to Jupyter server, which is an annoying behaviour.

I browse for help, so I change the "security.fileuri.strict_origin_policy" to false, but didn't help

I verify that Firefox let me navigate my personal folder, but deny access to hidden folders (name starting with dot). I test this behaviour by create a new directory in my personal folder (navigable) and then change the name by adding the initial dot (access denyed).

I guess this is an effect of security policies of Firefox, but how can I change this policy in a safe way?

Hello, when I search firefox in Ubuntu snap store I see two firefox: Firefox web browser V 108.0 build2 238.8MB and firefox v 108.0 250.5MB. There are both safe? Which one to install?

We have an Ubuntu computer that opens Firefox in Kiosk mode automatically when the computer boots.

This computer is connected to a TV and is used as an informational dashboard. No user interaction is required, so no keyboard or mouse is connected.

Every so often, Firefox updates (among other updates) and the computer reboots overnight. When booting after a Firefox update, it shows a "thank you for loving firefox" message instead of the specified URL. The easiest fix is to hold the power button and manually reboot when this happens since there is no keyboard and it's quicker than logging in via SSH.

Is there a way to prevent this message from showing after updating? We want to keep the automatic updater enabled to keep it up to date, but this is not desirable behavior.

I follow the instruction in the kb of firefox to reset the download settings. But i keep not being able to download any file from any website. I currently have the version 107 in Ubuntu. This problem occur after the last upgrade. How to fix this? Thank you.

I've only been having it issue since upgrading to Ubuntu 22.04. Firefox (103.0.2) will lock up (not the pc, it will keep working in other apps). It doesn't seem to matter about the number of tabs open, or what sites I'm accessing. It 'seems' random, and closing Firefox and reopening it seems to work for a short while before locking up again. I'm not a tech guru so I don't know exactly what to include here, like logs, or other info. The other issue associated with this issue is, when it locks, and I restart, Firefox does not start the first time I click on it. I have to click on it again and when I do, it will start, but usually (not every time) I get an error message along with the open home page of Firefox. I have to press the (not sure what to call it) windows key and switch to the error to close it. In the past, I've always had a great experience with Firefox, but this is starting to really be annoying! Especially when I have four of five tabs open and have to do a restart. Firefox doesn't seem to realize it's had a problem so the option to re-open tabs with a restart doesn't happen. So I have to use history, which can be troublesome and confusing, to get back to the pages I was reading. I only open multiple tabs most often when I'm researching an issue and want to 'order' the tabs so I read the ones that look like they apply the most to my research topic. So it really is an annoying issue. So much so, that I have been looking to switch browsers. But I really do not like the large commercial entities not to name names, but I may have to suck it up and install the Big G's browser, the Big C! )^: (note: if you respond requesting additional information, please be kind and offer how to obtain the info! Thanks!)

I can't play a video when logged into a website - see https://support.mozilla.org/en-US/questions/1371380

I'm sure it is not Firefox as I have also tried Chrome and Opera; same problem. How can I debug this and find out why the video cannot be played ?

I see there is 'Remote Debugging' and 'Browser Console' under 'More Tools'. How do I use these or other tools to find out what is causing the problem please ?
