I have the HTTP_PROXY, HTTPS_PROXY and FTP_PROXY (and their lowercase counterparts) exported and then the firefox binary is started from the shell script. The settings in firefox say it will 'Use system proxy settings'. Nevertheless I do not see the proxy being used as I can not access the web pages that need the proxy. The 'about:config' also does not show that firefox picked up any proxy related information from the shell environment.

I know the proxy address is correct because if I use brave browser instead of firefox (same shell script that launches brave) I can reach the web pages behind the proxy as expected.

Hi! I'm using Firefox 126.0 on Fedora 39.

Pages from Amazon.co.uk load very slowly, incompletely, or not at all. All other Web sites are fine.

I had a couple of certificate-related errors saying that the identity of the site couldn't be verified, but I can't reproduce the problem, so I can't quote the exact wording, I'm afraid.

The same Amazon pages load properly in Chrome on the same machine, and they load properly in Firefox in a VM on the same machine. That tells me network connectivity must be fine.

I've tried disabling all extensions, reverting to the default theme, running in Troubleshoot Mode, clearing cookies and site data, clearing the startup cache, disabling hardware acceleration, and creating a new profile. The new profile helps slightly, in that it loads more of the page before getting stuck. Nothing else helps at all.

I'd prefer not to refresh Firefox if I can avoid it, because I don't want to lose all my plugins and settings. This installation is five years old. Besides, a new profile didn't fix the problem.

What's the next thing to try? I'd really appreciate any ideas.

Hi there,

On Firefox, I'm experiencing "momentum" scrolling where, when I scroll using the trackpad, after I lift my fingers off, it keeps scrolling for a bit.

This is not the same thing as smooth scrolling. Disabling smooth scrolling does not disable this behaviour, and I use smooth scrolling on plenty of programs without it experiencing this "sliding" "momentum" on any of them except Firefox. I've also used Firefox before with trackpads without experiencing this.

How can I disable this?

I can't get Firefox to use some custom cursors. Firefox is only recognizing the cursors that came installed with Ubuntu. Any of the cursors I installed will default to DMZ-White, but Firefox is using those cursors that came installed with Ubuntu. I tried defining the default cursor in /usr/share/icons/default/index.theme but did nothing as well. Also I tried with the cursor in /usr/share/icons and in /home/name/.icons and firefox cannot get in any of those.

I don't know if it's something wrong with my cursors or it's some inner thing with Firefox, any one has a guess? Incompatibility or something missing from the cursor?

Twice in the past 2-3 weeks I have had to restart the computer, Linux Mint 21.2 Firefox 124(when updated in the past couple of days), due to the mouse freezing up and not being able to move the mouse on the screen. That's not the current problem, but it might help direct things to the final solution.

After the most recent reboot last night now I'm having a rather problem. The up/down arrow keys are no longer scroll me up and down a webpage like they always have in the past. Instead of doing smooth scrolling like they always use to, now they are scrolling me up and down the links on a web page. For example, if I were to be on youtube it would first want to scroll me down the left side links before taking me through each and every video link, when the page goes to load in more videos than it wants to go back and scroll me down the left side links again. It acts like it is taking me through the html code, line by line, instead of scrolling me smoothly down the webpage. The only way I can scroll smoothly down the webpage is to use the mouse on the scrollbar on the right side. It does this both in normal mode and in Troubleshooting Mode.

I have checked and beret scrolling is false as well as beret_shortcut. Use autoscrolling, use smooth scrolling, show scrollbars and always underline links are all clicked on. Always use the cursor keys to navigate within pages is unclicked. I have tried different changes between clicking on and unclicking those options with no change being noticed.

How can I get this back to the way it used to run?

Hello folks

According to Firefox help pages, pinning an extension to the toolbar should work as follows:

"Click the extensions button (jigsaw puzzle Fx109ExtensionsButton icon) in the toolbar to open the extensions panel. Each extension in the panel has a menu button with a gear Fx91GearIcon icon. You can use this menu button to manage those extensions."

The extensions button doesn't seem to work like that for me. When I click the Extensions button I get several buttons (Recommendations, Extensions etc) on the left side of the page as in the first image attached (Firefox1).

If I then click the Extensions button I get to the Manage Extensions page, and if I then click the 3 dots (...) button on (say) Proton Pass I don't get a Pin to Toolbar option and clicking the Manage option opens the Proton Pass Details page (see image Firefox2) - none of the buttons on the any of the pages offers a Pin to Toolbar option.

Those extensions that are pinned to the toolbar, such as Adblock Plus ( see Firefox2 image), got pinned during installation and not by using the extensions button. Currently I seem to have no way of interacting with any extension via the extensions button.

Could be I'm doing something silly but any suggestions would be appreciated.

I have several machines on my local network. I work on machine A, and run applications remotely using ssh -X on the other machines. Today I discovered that when I start Firefox on newly-upgraded machine B, it's actually starting the older version that's on machine A. This seems obviously wrong, and is certainly not what I want to happen. I want to run the newer Firefox that's on B, and have it display on A.

Longer details: A runs OpenSUSE Leap 15.0. B runs Leap 15.4. I start an xterm on B with the command " "ssh -X -l me B", and programs other than Firefox I run from that xterm display on A's monitors, as expected. However, when I try to run Firefox (by typing "firefox &" on the command line, what actually runs is the older version of Firefox that is on A, just as if I'd started it with the same command on one of A's terminals.

Is this a known behavior, and if so, is there a way to work around it? Or am I just doing something really stupid?

Hi there!

I'm attempting to migrate my Firefox (106.0.3) profile from the Linux Mint V20.3 on one SSD to a new installation of Linux Mint V21 on a separate SSD. I'm using the information supplied on this page:

https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles

Step 4, under Backing up your profile says: Right-click on your profile folder (e.g. xxxxxxxx.default), and select Copy.

This folder, qspfoqtl.default, contains 1 file, named times.json, the contents of which are:

{ "created": 1618792039414, "firstUse": null }

Clearly, not my Firefox profile.

There is, however, a folder named nnob5aww.default-release that contains a bunch of directories and files (505.4MB) with names like bookmarkbackups, browser-extension-data... storage, weave.

Is this documentation incorrect as of this release of Firefox? And, should I be using the nnob5aww.default-release folder as the profile? I'm a little confused. (Most often, I'm a lot confused.) Any help would be appreciated.

Thanks in advance,

- Ralph

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:

This opens a search page that doesn't follow my dark theme. When I click on a link, another link is added that creates a link back to the same URL, causing a loop. This never happened before I upgraded to Ubuntu 22.04 & the latest version of Firefox, 100.0.2. How can I change this back?

Hello Good People,

I noticed that the snap version of Firefox had a lag issue when typing into input field. For example, when composing an email and wanting to use backspace to quickly delete a misspelled word, then backspace works slowly, stuttering and jittering. If I hold down a key in the input field it also lays the character down in a stuttery, slow way.

I tried reinstalling the system and that solved the issue. But it has returned again. Maybe it was an update. I also installed WINE and waybridge to get some windows plugins to work on my DAW. I don't know if that has affected it.

I also tried removing the snap version and installing firefox using the terminal but the problem persisted.

It's an annoying problem. Any advice appreciated.

Hi - new to the forums.

I have a fairly retrograde, request :slight_smile:

I want to have Firefox operate with ONLY ONE tab on screen at any time!

By That I mean, whenever I try a new search ,or open a new link, I want it to REPLACE the one and only existing tab always. Firefox will only ever have one tab on the screen- no multiple tabs allowed.

Is this possible?

Dear Technical Support,

I'd like to report a problem which affects the rendering of websites in Firefox with a HiDPI monitor.

I'm having issues with the text and graphics of web pages, that are often mismatched or misaligned, with text being too large compared to graphical elements. See the enclosed pictures for an example; as you can see, this happens also on your website. Also, I've noted that pages (and plugins) appear to be "shrinked" as opposed to when viewed on Chrome, where they are shown to their true size.

Setting ui.textScaleFactor=100 and tweaking with layout.css.devPixelsPerPx did not change much. I must admit that I find this behavior quite strange, since HiDPI monitors have been around for more than a decade, and especially considering that this did not impact my experience with Firefox on Windows, using the same monitor and machine.

I hope to find an effective solution to this problem and look forward to your reply. Please let me know if I can be of any help in this matter.

Best regards, Federico

Hi. I was suddenly having unexpected problems to log in in a site (https://www.lanacion.com.ar/). So I updated FF but the problem persists. Then, I uninstalled FF, downloaded it again from the repository and installed again, but the problem persists. Then, I downloaded directly rom the Mozilla site, expand it in the desktop and double click the program icon. The program opened and I was able to log into the site I was trying to. Interesting enough, the browser opens a lot faster than when installed. My question is: everywhere on the web the response is "you have to install the program" or "the program is already installed in your distro", which is true in my case, but one day stopped to work properly. BUT I'm not installing it, and it works apparently well... ¿how can it be? Thanks in advance for your reply. -Enrique.

Under about:config I set xpinstall.signatures.required, xpinstall.whitelist.required and extensions.langpacks.signatures.required to false. Then I went to about:addons clicked on install add-on from file and selected the zip file. I got the error message: "This addon could not be installed because it has not been verified". I am using Firefox for archlinux, version 112.0.

Also, re-merging the tab with another firefox window stops working. (Dragging a tab to a firefox window from another firefox window doesn't merge them. It does nothing) I can right click on the tab and select Move to move it to a new window but dragging stops working. I have to close Firefox and start it again (sometimes twice), then dragging starts working again. This happens multiple times a day. I am on Linux Mint and the version is 126.0 (64-bit).
