Fóram Tacaíochta Firefox

Hi all, I have an Apache site on Kubuntu 20.04 with a certificate signed by my private CA. I've added the root CA ceritificate in Firefox and in Chromium.

Firefox throws a SEC_ERROR_BAD_SIGNATURE error

Chromium accept the certificate as valid

What can I do?

Notes: the site url is "https://hdev.h.net" (with an internal IP address inside my lab)

Attached there are:

- the authority settings page
- the certification authority certificate as seen by Firefox
- the site certificate

Firefox version 82.0 Ubuntu Chromium version 86.0.4240.11

No matter what I tried, I can not delete my browser history, nor can I delete single websites from my history. The history list works fine, all visited sites are visible and browser history is updated, but I can not delete any of the entries or the whole list. I have uninstalled and reinstalled Firefox, but the problem is still the same. I have read and write permissions on the .mozille folder, so this can not be the problem.

I have switched from Windows 10 to Ubuntu 20.04.1 and am having trouble creating website shortcuts now. With Windows I used the following method

• [Support - Create a desktop shortcut to a website]

From my research it looks this is supposed to work with Ubuntu as well? It is not working for me, is this possible?

Hi

I'm an Computer Vision engineer and I migrated from Chrome recently.

The problem is, when I train a neural network and GPU utilization goes beyond 90% Firefox becomes unusable and sometime freeze my whole PC entirely.

I'm not even talking about YouTube or video sites, just new tab is enough to cause problem.

This never happen in Chrome and I'm forced to keep using it every time I need to use GPU.

Is there any tip for this?

Recently, I had to change my username at my bank's website because somebody was trying a brute force attack on my password. Now, the site still shows my old username, although I've gone to my Saved Logons in Preference and removed all logons for that site except for the correct one. I have to delete the old username from the typing box every time I log in there, after which I can select the correct (and only) saved username/password.

I had to reinstall Ubuntu 20.04 because I removed vital Python 2 and 3 and it broke. Before doing this I was logged into my Firefox profile and should have had my bookmarks and extensions synced. I do not see any reason why this would not be the case. However, after my reinstall of Ubuntu and logging into Firefox profile all of my bookmarks and extensions are gone. I tried checking around Firefox and it only shows bookmarks and extensions from after my reinstall. I have not performed a backup since I reinstalled Ubuntu, but those bookmarks are there. So I don't understand why I can't find my old bookmarks and extensions from before my Ubuntu issue, because I was logged into my Firefox account. My Firefox account information should have been saved to my account not my computer anyway. Please help me I had a lot of important bookmarks on there, but can't remember all of them.

Hi, i found a Problem with the Nvidia Website https://www.nvidia.de/Download/index.aspx?lang=de

When i Search for Driver Download, i choose "Producttype" and then when choosing "Product Series" the Website allways Resets to Start.

I also Informed Nvidia about the Problem, but it is only on Firefox. Im on Linux (Ubuntu 18.04) and use Firefox in Latest Version 83.0 no addons.

I also Try Chromium and other Browsers but this Problem only happens on Firefox.

Hey there,

I have the following issue with Firefox, is this maybe something I should report to the Ubuntu support or directly to Bugzilla?

Steps to reproduce: ---

1. Open Firefox
2. Go to a page that contains an embedded video that is not playing automatically, e.g. https://www.rottentomatoes.com/m/sound_of_metal
3. Do not play the video

Environment --- User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:83.0) Gecko/20100101 Firefox/83.0 Firefox version: 83.0 (64-bit) pulseaudio version: 13.99.2 OS: Ubuntu 20.10 64-bit Gnome version: 3.38.1 Windowing system: Wayland CPU: Intel® Core™ i7-8565U CPU @ 1.80GHz × 8 RAM: 15,5 GiB GPU: Mesa Intel® UHD Graphics 620 (WHL GT2)

Actual results --- pulseaudio process is spawned and rapidly becomes the most CPU consuming process on my machine (especially after a few seconds, when the Web Content ones start to cool down). Even though no sound is actually played! When switching to another tab with no embedded video, pulseaudio keeps overloading the CPU. This only stops after closing Firefox.

Expected results --- I'm not sure this is what should be expected, but I'll give it a shot:

• pulseaudio process should only be spawned when actually playing a media that requires audio
• pulseaudio should not be the #1 CPU consuming process
• pulseaudio process should at the very least not massively use CPU when no sound is playing

'''i tried to start screen share but this happened''' camera is not supported by your current browser.

can anyone please tell me how can i fix this.

The page Give feedback landing page says: ‘Please check back soon’. What does ‘soon’ exactly mean?

in about:config page the options: browser.tabs.warnOnClose (true - default) browser.tabs.warnOnCloseOtherTabs (true - default) browser.sessionstore.warnOnQuit (false - default) browser.warnOnQuit true (true - default)

But when i do Ctrl+q accidentally, it closes the only Firefox window i have. This window has many tabs open. Yes it restore next time, but i want FF to ask me before closing it.

FF 84.0.1 Arch Linux

When Firefox asks if I want to download an update and I agree, soon after that but not right away it stops working - on every new page it says "We need to restart to finish updating" <- This last bit is VERY annoying. Is there a way to keep FF working in such situation? I usually have 3 FF profiles running, about 10-20 tabs each and when it suddenly does this - I can restart them all but when it is suitable for me.

The only solution I can see so far is disabling updates via group policies (which is not well documented, where do i put this policies.json on Fedora? need to google that).

Any other ways to keep updates and FF running until I decide when to restart? Thanks.

I am using Firefox with Default Search Engine set to Duck Duck Go. I seem to be unable to connect to duckduckgo.com be it either through typing my search in the address bar or duckduckgo.com. All I get is: "Hmm. We’re having trouble finding that site." Internet connection seems fine (no trouble connecting to other sites). Sometimes clearing "Cached Web Content" helps but it is troublesome to clear cache after each browser restart. How can I get the Duck to work with the Fox?

Selected options: Use the address bar for search and navigation Default Search Engine - DuckDuckGo Delete cookies and site data when Firefox is closed

I would be happy to provide any additional information if needed.

and with some chrome extensions but only 3-row tabs, different color on unloaded tabs and show X on hover thats all my usechrome.css

if u need any more logs i am open to share them. how do i fix this problem?

“连”、“设备” are Microsoft YaHei(MSYH), but the others are other fonts which are not on my computer, and although my settings are zh-CN, my language pack is zh-CN, my Default Font is MSYH, the bold characters are JAPANESE STYLE CHINESE CHARACTERS. Maybe it is because in your font-config, ja-JP is former to zh-CN, please fix it.

On Ubuntu 20.04 using Snap 84.0.2 (64 bits) there is something wrong with close button, presented in the attachment.

The X seems corrupted.

Does anyone know how to fix that?

Why can a stupid failing script on a web-page, or even intentionally so programmed script disable the copy (and sometimes paste) functionality?

How can this be disabled/fixed?

One highlights a text (any text) on some web sites, Edit menu allows Copy, context menu allows Copy, one hits Copy, nothing happens. It's not even a page where someone wanted to "copy protect" some information.

Copy and Paste should work just as advertised since those were invented, how hard can it be to get that right? Even stupid Notepad never fails at it. And no, I don't care what the idiot who programmed a page though would be/should be best for me, I want Copy to be copy, Paste to be paste. This used to work in "original" Firefoxes even when page developers wanted to make it not work.

And yes, while on a given page Copy fails miserably, at the same time in other pages it works.

The question at the following URL has an answer that is no longer the best answer, but it is Archived and I cannot provide the better answer. Since "How can i reset 'container defaults' in FireFox Browser? I.E. I previously selected to open a certain 'site' is a specified 'container' - now I want to clear." is the top hit when I look for this on Google, I'm attempting to provide the answer here.

# Ubuntu garbage data increases exponentially

## Intro and context

Hello. I am a power user that works in software and web development. I have been using Firefox on and on for most my life, but full time as my main browser since late 2018. One thing I love Firefox for is its lightness on memory compared to that of Google Chrome, and also its open web standards, open source, privacy, ethical owners, and customizations. I have been using Windows 10 up until July 9th 2020 before I switched to my first main Linux desktop. I have always kept my eye on CPU and RAM usage, as high CPU drains battery and running out of RAM results in a system crash. I actively keep many tabs open (less than 100 but more than 60) I ensure that they are light. I mostly have GitHub tabs open, but I keep a few other things open as well, mostly Wikipedia/wiktionary and duckduckgo tabs, a pcloud (file service) tab, but sometimes a youtube tab or two (rarely a reddit tab)

## Issue

I have been noting that garbage collection is getting exponentially worse over time. When I got my laptop, I was able to keep 2-3 fully packed profiles open at all times, and never having to close Firefox until shutdown (after about 12-16 hours uptime) I rely heavily on Firefox profiles for organization. It has been getting exponentially worse. Starting in late 2020, I had to reduce the max number of open profiles to 2, and in 2021. In early January, I had to start closing the profiles once a day to free up 2-3+ GiB of RAM (swap doesn't change much, that is the garbage data that isn't being cleared, it normally ends up at 800 MiB to 1.7 GiB by the end of the day) and now (as of January 22nd 2021) I have to close Firefox 2-3 times a day to prevent my system from getting overloaded, as Firefox eats through 1-2 gigabytes of RAM per hour, even when idle. I have noticed several processes titled `web content` that use 200-600 MiB each (there is usually 2-7 of them) I am wondering what I can do for Firefox to prevent high RAM usage. For reference, here is my main profile in idle mode:

Mozilla is refusing to let me upload images right now, so I will link them

https://github.com/seanpm2001/seanpm2001/blob/master/FFTechSupport/Jan22/MProfile1_Idle_1.22.2021.png

Here is my usual 2nd profile in idle mode:

Here is the RAM and SWAP usage before my 2nd refresh today (uptime: 8 hours 46 minutes)

And here it is with Firefox and Nautilus closed (I forgot about nautilus before getting the first 2 pics, it uses a lot of memory depending on its usage):

I have lately suspected that GitHub may have gotten heavier, or is sending too much data via AJAX methods, but I am not entirely sure.

1. 1. System specs

Firefox version: `84.0.1` - I haven't updated in a while due to fear of memory increase and instability

Number of Firefox profiles: `61` - no new profiles created since December 26th 2020

I am wondering what I should do about this. I work with hundreds of projects, so I can't close too many tabs, as it becomes hard to access and manage. I intend to close 16 tabs in the next month, as I am freeing up some projects.
