Hello Volunteers,

Ubuntu crashes while moving around a Firefox tab with a mouse, IF the mouse cursor goes thru the top bar of the laptop screen. I am using Firefox V 113.0.2, Build ID: 20230522193126 on Ubuntu 23.04. This could be an Ubuntu problem or a Firefox problem.

Thanks Dilip Deodhar

Hello,

I have more than 30 extensions, but I cannot add an extension shortcut into my toolbar and no extension appears in the “Customize Firefox” view. I tried “Restore defaults” without any effects...

There is a way to fix this issue or run Firefox in verbose mode to more information why my extensions don't appear here? (Other than restart from a new fresh profile if it's possible…). I confirm that all the extensions are functional and activated. Thanks,

Emeric

Does anyone know how to configure Firefox to stop the annoying google log-in pop-up? I've seen others ask the same question, but I have not seen any functional answers. I've never had a google account, for anything. I don't get the pop-up with other browsers, like Falcon or Brave. It's just a problem on Firefox. I appreciate you help!

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:

Firefox worked perfectly, but since a few days I can't download anything. I'm using Mozilla Firefox snap for Ubuntu 22.04, version 110.0.1 (64 bits) canonical-002 - 1.0 With Chrome everything works perfectly so I assume it's a problem from Firefox.

When I open a PDF, a MP3 or any file, the "save" option doesn't display anything. Usually it opened a dialog where I could choose the folder where I wanted to download the file, but now I have nothing.

I have only 4 extensions: - adblocker ultimate - duckduckgo privacy essentials - vuejs dev tools - zotero connector

I always had them and I never encountered any problem.

When I click ctrl+q by mistake, the browser window with all its tabs is closed immediately, with no warning. This has already made me lose data. is there a way to disable this keyboard shortcut?

I just updated Firefox to version 81.0 in Linux, Windows and Mac, but the credit card autofill option is still missing from the Preferences menu.

I followed the instructions from here:

https://support.mozilla.org/en-US/kb/credit-card-autofill

Yes, I am located in the US.

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.

When I download a file and click on the downloads button to bring up the Downloads menu, I often just want to open the Linux Mint file manager in the right folder so I can move the file to a more appropriate place.

In the menu, there's the little button to the right of the listed downloaded file with "Open containing folder", but if I click on that, FF opens the downloaded file, not the file manager.

Obviously this wasn't always like this, but I don't recall doing anything that might have caused the issue. How can I set FF back to the default action of opening the Linux Mint file manager?

Thanks!

Hi, how can I open a local html file with firefox 86 on android 9? It's like firefox no longer registers itself as a valid program/association to open html files.

What I've tried so far: 1) If I type file:/// in the URL bar, nothing happens. It works on Opera. 2) If I go to a file manager, select an html file, and click "Open with", firefox doesn't show up; Chrome and Opera do. 3) If I go to the android settings > applications > firefox > associations, firefox shows no associated file types at all.

The HTML language isn't only used on the Internet, it's also used for local documents, please allow us to use firefox to view our local html files.

I was following this reddit thread on how to remove the "your camera and microphone are being shared" popup, but it's having no affect.

I have set `toolkit.legacyUserProfileCustomizations.stylesheets` to true.

Here's the full contents of the userChrome.css file: ```

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");

#webrtcIndicator {
  display: none;
}

After installing Ubuntu 20.04 LTS Clicking on Firefox or Thunderbird it hangs the computer and have to switch off the computer on main switch. Reinstall Mozilla once but no difference still hangs Ubuntu. Need help on this one Thank you

Today I updated my Firefox Developer Edition to version 89.0b2 and now I just can not look at this browser anymore, "Inspired new tab design" is taking too much space and now became largest and at the same time least information-dense panel in my entire desktop! I searched around the web for a bit in hopes that I will find a theme or an add-on that will revert this particular change but no luck. I really want to revert to old UI look (at least tabs bar), there should be default theme or option to get back to old style. After some investigation I found userChrome.css but don't really want to install it (maybe this is actually the way of doing this kind of styling). Please help me revert UI design to old one.

I set about updating my e-mail address on this forum. I followed a hyperlink which had been e-mailed to me automatically in the past by the forum, and which pointed to support.mozilla.org

The first screen (whose URL I don't want to try to get right now because doing so might sign me out of my Support.Mozilla.org account) offered only an option for creating a new account, not signing into an existing account. It turns out that this is a very significant wording mistake that needs to be corrected.

Since I thought my existing account didn't exist anymore, I made a new account with my new e-mail address.

Then I found that the short username assigned to my new account had a "1" suffixed - which meant that my existing account did exist after all. So I deleted the new account. I also managed to sign into my existing account by using the misleadingly named "Create a new account" method.

The next problem was how to change my primary e-mail address. There is no evident way to do this. I eventually found article https://support.mozilla.org/en-US/kb/change-primary-email-address-firefox-accounts which confirmed my suspicion that the recommended workaround is to add the new address as a "secondary address," then delete the primary address. This is another significant issue that needs to be corrected. I'm registered on possibly dozens of Web forums etc. & all of them (except Mozilla) simply let me change my e-mail address when I need to.

Anyway, now apparently the support forum doesn't let me add my current e-mail address as a secondary e-mail address, because there is still a record of this address on the defunct account that I just now created. Also, the error message here is worded incorrectly (it claims that my new e-mail address is the same as my old e-mail address).

Can I please have assistance from a forum admin in getting my e-mail address updated, without change to my short username.

I also wish there were a more obvious way to ask for help (or raise defect reports) regarding the forum itself.

Thanks for your help.

I just used pacman to update to the latest Firefox, but the tab crashed each time I open a new web page ( I can open settings, about:xxx and etc... ). I tried Troubleshoot Firefox crashes and it did not crash in troubleshoot mode. Then I tried extensions, themes and hardware acceleration issues to solve common Firefox problems https://support.mozilla.org/en-US/kb/troubleshoot-extensions-themes-to-fix-problems but non of these options solved the problem. I disabled all extensions, themes and hardware acceleration, and it reported the same error.

I want to set 2 preferences regarding syncing as default preference for all (new) profiles. 1. sync toolbar layout. 2. set my own sync server path.

I already know how to do this via about:config manually per user. I want to have these 2 preferences by default for all users.

On Ubuntu 21.04, I followed these instructions to the letter, but it has no effect, tested on a newly created profile: https://support.mozilla.org/en-US/kb/customizing-firefox-using-autoconfig

I created: /usr/lib/firefox/defaults/pref/autoconfig.js And it contains exactly what is in the instructions.

Also created: /usr/lib/firefox/firefox.cfg Looks like: ``` // IMPORTANT: Start your code on the 2nd line defaultpref("services.sync.prefs.sync.browser.uiCustomization.state","true"); defaultpref("identity.sync.tokenserver.uri","https://ffsync.mydomain.tld/token/1.0/sync/1.5"); ```

Then I create a new profile and check via about:config, unfortunately the first preference doesn't exist (note it doesn't exist by default) and the other is not applied, I still see Mozilla sync server path.

How can I set these 2 customisations globally. for all future users (preferably also current users)?

In Ubuntu 18.04, I bring up a new page, click in the search bar in the middle of the page. Then when I start typing it jumps to the address bar although I have already placed and preferred the search bar to the right. No! NO! NO!

I use Duck Duck Go but Google does the same.

It is bad enough that the upgrade was automatically loaded but on top of that, changing preferences including dumping my home page. Change privacy settings without asking ( to a lower level on top of that ).

Really POOR form.

Platform: Raspberry Pi 4, Ubuntu MATE 20.04.2 (Linux 5.4.0-1036-raspi) , Firefox 89.0+build2-0ubuntu0.20.04.2

When displaying video (e.g. youtube) and graphics, the output show "image noises".

I have taken an snapshot and attached an screendump.

The areas enclosed by Thick Black Pencil shows the symtom.

1. Previous version of Firefox ( 75.0+build3-0ubuntu1 ) did not have the problem.

2. Other browser (e.g. Chromium) displaying the same video does not have the problem, so it seems it is Firefox related.

3. In a certain extend, this also affect outside video frames within Firefox evem in Settings page, see second attachment.

Please kindly shine some light.

The Firefox account settings page displays a list of logged in devices at the very bottom of the page (connected services).

I have verified all logged in devices to be correct. However for one of the devices (my main computer browser), the location displayed is COMPLETELY off. I live in Norway, and it claims device location is somewhere in Oregon, United States. I do not use any VPN services and both my public IPv4 and IPv6 addresses are located in Norway, from which I connect with the device/browser in question (whatismyipaddress.com shows correct location for both of them). Also, activity timestamp is updated in accordance with my own activity from the client, but the location remains wrong. I also tried logging out the device, and logging back in, but this did not fix the location.

Obviously the location service used for the logged in device list is unreliable. I suggest that you please also show the latest IP address used by each device, so that more technically inclined users can verify correct addresses themselves, should the location be way off. It is unsettling to see strange locations (for known devices) on a page used to verify the security of my Firefox account. In this instance, there is no security breach, but it required me to spend much time investigating.

I do not know if it matters, but the device in question is a Linux desktop Firefox client.
