Fóram Tacaíochta Firefox

I am using Firefox 95.0.1 on Ubuntu 20.04. When I want to use an add-on in google docs, I see this error screen in Firefox. Opening the add-on in a separate window does not work either and even if it did, it would be off the purpose of a google doc add-on. How can I solve this problem?

Local Machine: Dell Inspiron i5-7200 / 16 GB RAM / Local Op Sys: Ubuntu 20.04LTS

Firefox version: 99.0 FFDE version: 100.0b5

Node.js version 14.18.1 npm version 6.14.15

I had a Node.js web app running on my local machine all usual browsers like Firefox, Firefox Dev Ed (FFDE), Chromium, Edge, Opera, etc till recently.

Recently it shows an error when run on Firefox (also on Chromium, Opera and Edge) although continuing to run okay on FFDE.

Firefox Error: Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at file:///home/sandbar/Desktop/nodeapp-local/undefined. (Reason: CORS request not http).

Edge Error: Access to XMLHttpRequest at 'file:///home/sandbar/Desktop/nodeapp-local/undefined' from origin 'null' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome-extension, edge, https, chrome-untrusted.

Naturally, I need to test the web app on my local machine using several browsers before I should upload it to a server and trial it there.

So how do I configure the browser and/or app to allow access to local machine files ?

FF updated yesterday with the new Ubuntu 22.04 (Pop) update to 99.01. Since the update the volume control inputs are essentially disabled on all web sites, and they default to max - even when muted.

Example - youtube - all videos play full volume Reddit - even muted videos play full volume

The volume can now only be controlled by the system slider.

The same behavior does not occur in other browsers - e.g. Chromium, Opera, etc.

Can anyone assist?

Hi, wonderful crew I have this annoying issue: when I want to print a page and I open the Print menu from the "hamburger" button, the preview open but on the printer list I can see only the PDF printer, not my default printer or any other printer. Also if I click on the link "Print thru the system printer window" I see only "Print on file" and "Print on LPR" I tried the same on Chomium and there I can see my default printer My system is a Ubuntu desktop 22.04 recently updated from 20.04 LTS Thank for your work

OS version: Ubuntu 22.04.1 LTS (jammy), 64-bit (amd64, x86_64). Firefox version: 110.0 (64-bit) (NOTE: the issue was noticed with version 109.0, too)

Firefox package was installed on Ubuntu through 'APT', using the Mozilla Team repository (https://ppa.launchpadcontent.net/mozillateam/ppa/ubuntu/). It caught my attention that an excessive amount of Firefox related 'DENIED' AppArmor log messages is generated during the browser activity.

According to messages, Firefox is occasionally denied read access to '/sys/devices/' area and read/write access to 'oom_score_adj' target in '/proc/'. Could somebody clarify why would that access be required for regular browser operations? I'm a bit puzzled as I haven't noticed anything similar with the older Ubuntu and Firefox versions. A complete suppression of those messages is also an option as long as there's no negative impact on application's performance.

I already posted this question to Ubuntu forum but seems like nobody there could provide an explanation. I'd appreciate any input or hint.

Following is the sample of referred log messages:

Hello everyone, i'm currently on ubuntu 20.04.2 LTS, and pretty frequently 1/2 times a day, when I'm on youtube, the browser just starts messing up completely the audio. It is delayed by at least 2 or 3 second, and it is all confused by a really awful interference noise. The problem goes on if i don't restart my browser, or sometimes even my pc. I tried disabling hardware acceleration but it doesn't work

What is going on with Firefox on Linux? It's been my favorite browser for years and I want to stick with it, but it becomes unusable.

I've got 32GB of RAM, so I should theoretically be able to open quite a few tabs (which I need as a web developer), but when I have about 15 tabs open, it consumes about 1GB of ram per tab. Usually I have some webmail tabs open, google drive, youtube, some documentation and references, github, example sites... you know, the usuall stuff you find in a web dev's browser.

I'm running the latest updates on Ubuntu 20.04 and have the latest Firefox installed. On my Windows (dual-boot so the same computer, but windoze is more for gaming than for work), I can open 50 tabs and have no memory issues at all. I'm syncing my extensions so it's the exact same configuration, yet on Linux it's huge a pain in the behind to keep using it.

Are there any fixes for this? I've seen other complain about similar issues for previous versions of Firefox and other Linux distros, I've ran through all the self help suggestions and nothing helps.

Hello,

what can i do when i get a message "Sorry. We just need to do one small thing to keep going." with <Restart Firefox> or "Gah. Your tab just crashed." all the time i open firefox? A restart with Add-Ons disabled does not help. I send the troubleshooting information from Help/Troubleshooting information. As one can see Firefox does not seem to produce crash reports either.

Kind regards Atomino Zweitausend

Starting today, with firefox 102 (on Ubuntu 20.04), I cannot open a url using the address bar. If I enter a url and then hit Enter, it brings up my selected search engine looking for that url, not opening the url itself. This has not happened before today. Is there a way to use the address bar only for opening addresses, and use the search bar for searching?

Firefox crashes (tested in troubleshoot mode) for this URL : Link which causes crash https://developers.google.com/android/guides/opensource#java

There are no crash logs generated either (checked in about:crashes) . Attaching a post-crash dialog screenshot

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])

Hello, This issue might or might not be related to [other issue] I have since I updated Ubuntu 20.04 to 22.04 and therefore updated my Firefox to 104. I can't login anymore on Letterboxd since the update. It's not a problem of username or password. When I click "Sign in", nothing happens except a page refresh, but I'm still not logged in. Other strange behaviour on that site since the update: most of the images don't appear. For example on this page : https://letterboxd.com/films/# all the movie covers are just blank.

The website does work properly when using Firefox in private mode though (both login and images work fine), so this makes me think it's related to my other issue mentioned above.

OS: Ubuntu 22.04 Firefox 104.0.2

EDIT after posting this question: I just found out that I can't login on Google either. I enter my username, password, then it asks me to validate on another apparel that it's really me, which I do, and nothing happens so I can't login. It works normally in private mode.

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?

I first realized an issue with downloading PDFs through the Firefox viewer - I cannot. The download button does nothing, there is no prompt, no popup, and no file downloaded. I have also tried to print to pdf, that also seems to fail.

Today I realized I also cannot attach any files to an email through Gmail in Firefox, which is now leading me to believe that the software is unable to interface with my files at all.

Things I've tried include: - Turning off popup blocker - Refreshing Firefox in the ->Help->More Troubleshooting Information Menu - Starting Firefox in safe mode - Reinstalling through snap

The only way I can currently download files is through wget, and the only way I can send attachments is by installing Google Chrome, which is kind of a last resort for me.

I am running Ubuntu 22.04, this is on Firefox 106.0, though it didn't work last update either.

Thanks for any help

Edit: I have been googling for answers but after posting this question a similar thread popped up, the solution is to install the following packages:

xdg-desktop-portal xdg-desktop-portal-gtk

Whenever a website prompts for me to upload or download a file and I except Firefox crashes, quitting in its entirety. This still occurs in "Troubleshoot" mode so I assume it is not any of my extensions. Here is a crash report from when this occurred if it helps. Another odd observation I made is that I am able to upload a file if I use a "drag-and-drop" feature on a website.

I often use two firefox windows each with several tabs opened

Problem is when I quit in this state sometimes only one of those multiple windows gets opened on the next launch

To quit I do a `ctrl + q` or right click `Quit` from launcher bar

Is there a setting to tell firefox to always relaunch with the same set of windows ?

I use sync and this happens when using the same computer for the exit then relaunch of firefox

firefox release 112.0a1 (2023-03-05) (64-bit)

when I open a website with some bold text, the bold text display not as exception. a black line on the right side of the char makes me mad. but it disappeared after zoom in 120% the page.

Hi there,

I'm using my PC for local web development. I use Firefox as my regular browser and recently, in order to distinguish between personal time and development time, I've established a new profile just for development purposes.

The local website I can't reach is "site.local.dev". My OS is Ubuntu 20.04 and that URL points to a local IP on my network (resolved via /etc/hosts file on my PC).

Funny thing is that: - In dev-profile: site.local.dev does not work => "Unable to connect" and the URL bar shows https://site.local.dev even if I force it to http:// - In personal-profile: site.local.dev does work :P

I have tried with CLI tools like "wget", "hosts", "ping", "telnet" and so on and the site loads ok. Even I have used Dillo (damn simple web browser) and the site loads ok also.

Things I've tried so far: - Suggestions at https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can - Suggestions at https://support.mozilla.org/en-US/questions/1011327 (similar issue, not exactly the same).

It must be a silly thing but I'm out of options now. Perhaps anybody has faced to this situation in the past: any suggestion on this issue?.

Thanks in advance, Ibon.

I saw where this was a problem with Netflix, Amazon Video and other sites with Fire Fox and that one person even used professional version and still had the same problem.

What I cannot see is where he got the video codex that allow Netflix to work on Fire Fox version 88, let alone this newest version that Mozilla has created.
