Dear friends,

I have Firefox Browser 127.0 (64-bit) installed. IFRAME is not displayed on some websites.

Example: https://www.rollerfreunde-untermain.de/gaeste.htm

Attached you will find a screen shot.

Can anyone say why this is the case?

Kind regards Uwe

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.

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.

Hello,

We are adding accessibility features to the Emmabuntüs Debian Edition 5 Linux distribution based on Debian 12, and we would like to use the reading mode included in Firefox to enable smoother voice reading for visually impaired people.

Currently we are going to use the Svox Pico and eSpeak speech synthesis at the same time because in SVox Pico we do not have all the voices we need for our possible users, particularly Portuguese.

We have found how to make the synthesis used by Firefox's reading mode be SVox Pico by default instead of eSpeak, however this requires a modification in the /etc/speech-dispatcher/speechd.conf file.

To do this, simply put the default pico synthesis in this file:

DefaultModule pico

But this causes problems with other software that we intend to use.

We found how to make all the voices of a speech synthesis appear in the Firefox playback menu by going to about:config and doing a search for the word "narrate":

Option narrate

On the other hand, we cannot find how to modify the "narrate.voice" option to tell it to default to pico speech synthesis instead of eSpeak synthesis which is the first synthesis loaded by speech-dispatcher, because we must keep eSpeak as the first synthesis loaded and do not put a default synthesis in speechd.conf to maintain compatibility with software that we wish to use.

Do you have any tips or a manual that explains the possible options for the "narrate.voice" option?

Thanks in advance for your help.

Hi,

I am using Firefox for Linux, and whenever my yubikey is plugged in, firefox will start bothering me for a pkcs#11 password. It always happens on start-up but it gets relentlessly annoying if I happen to be on a site which potentially utilizes certificate auth, which I do not use this yubikey for.

I do however use it for 2fa, which does work perfectly fine.

How do I permanently stop whatever Firefox process keeps bothering me about this PKCS#11 password for functionality that I never use?

Since this week I have been unable to access flightradar24 web site due to a problem with WebGL. It tells me that I need a compatible browser e.g. Firefox

I am running Linux Mint 21.3 Cinnamon on and I7 processor with a NVIDIA Corporation GK208B [GeForce GT 710] graphics card.

I have edited the about:config file as follows:

webgl.force_enabled TRUE

but noted a collection of failed messages as shown on the attached screen shot.

This web site is still accessible using chromium on the same computer, suggesting that there isn't a hardware problem.

Thanks

I'm setting up a user on a new computer. I've exported her bookmarks from her old computer. On the new computer I go to Bookmarks > Manage Bookmarks > (select bookmarks toolbar) > Import and Backup > Import bookmarks from HTML. I browse to my folder containing the bookmarks.html file, Open it, and nothing.

I've tried all the suggestions I can find. Places Database Verify Integrity gives me: > Task: checkIntegrity + The places.sqlite database is sane + The favicons.sqlite database is sane > Task: checkCoherence + The database is coherent etc. Opening the bookmarks.html file shows a list of bookmarks. That file is not empty.

This shouldn't be this hard. How do I accomplish this?

Hi. I was just looking at Google Photos on both Firefox and Chrome. Chrome had a bigger picture because the window had only the tabs bar and the address bar, and Firefox has an additional title bar. I was wondering if it would be possible to remove the title bar so the picture on both browsers were the same size?

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.

When opening a file from another drive, I get an error: Access to the file was denied

I know this can happen on the Snap version, but I have Firefox installed from a deb!

After updating to version 121, the cursor theme, while having it on the window, changes from the default one (Breeze) to Adwaita while also getting like 2x bigger. How do I change it back to default theme and size?

In the about:profiles page I can see that the Root Directory for my current profile is: /home/username/.mozilla/firefox/no9r1iq5.default-release-1681391696978 When I click the Open Directory button it does nothing. When I manually navigate to /home/username/.mozilla/firefox I can see that there is no folder there called no9r1iq5.default-release-1681391696978

The Local Directory is show as: /home/username/.var/app/org.mozilla.firefox/cache/mozilla/firefox/no9r1iq5.default-release-1681391696978 This exits and opens with the Open Directory button.

If I search for no9r1iq5.default-release-1681391696978 in the file manager, I see that there are two folders with this name, on at the Local Directory path shown above and the other at: /home/username/.var/app/org.mozilla.firefox/.mozilla/firefox My assumption is that this is actually the Local Folder (it contains files with today's date)

My question is, why does about:profiles show the wrong path for the Local Directory or why is the actual Local Directory in the wrong place (it appears that the path shown in about:profiles is the normal default location)?

I tried creating a new profile and it was created in exactly the same way: the Local directory path is: /home/username/.var/app/org.mozilla.firefox/.mozilla/firefox but about:profiles says it is: /home/username/.mozilla/firefox

I would rather have my profile in the normal default location but I want to ensure that I don't leave pointers to the wrong location that could cause problems.

I am running Firefox 121.0 (64-bit) from flathub on Debian GNU/Linux 12 (bookworm).

Any help appreciated.

Sometimes drag functionality stops working. I can't grab a tab to move it to another position or to a new window. (Holding left click on the tab and moving the cursor does nothing). 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). This problematic behavior has only recently began.

Hi,

I'm using Duckduckgo as my search engine, but when I type in a search string, it Firefox prepends it with https://html.duckduckgo.com/html/... 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?

Thanks!

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.

This is the same problem listed below. Recently upgraded to Ubuntu 22.04.3 LTS and Firefox 117.0 a few weeks ago and can't get the files to attach. In fact it won't open the file system. Tried removing all extensions as suggested and rebooting, but nothing changed.

I have an add-on ad blocker for youtube and have never gotten ads. This afternoon that stopped. I get ads with every video I click and there is no 'skip ad' on the screen. I added another top rated youtube add blocker, quit firefox and then opened it again. Before, if I clicked a video it started an ad and I could go back and then hit the video again, but now that doesn't work, but if I select to show the video in a new tab, there are no ads in that tab. What can I do to make the ads stop like they used to and never appear? Yes and my OS is Ubuntu 22.04

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.

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 everyone. Since installing Linux Mint in May 2023 I have been having this issue with Firefox.

Description of issue: When I switch between (or drag) tabs in a Firefox window, the whole window becomes unresponsive, with the last tab I was switching from still in front. Often the contents of the window start to flash (disappear and reappear, leaving a black backgground) every 2 seconds. I can drag the window around, scroll, minimize it, but it is impossible to give any input in any tab. The only action somewhat possible to do inside the window is bring other tabs in front, it is still quite hard for the input to register, and if it does, it takes 10+ seconds. The issue goes away if I close the specific Firefox window, or if I manage to select and drag one tab out of the frozen window into its own new window. Then everything works as intended, like nothing ever happened.

I can reliably cause the freeze-up in a short time by holding CTRL+TAB and drag one tab to change the order while firefox cycles through the tabs in the open window.

While the window is frozen, the rest of the desktop is responsive as normal, even other Firefox windows. If I try to interact with the frozen window I can rarely see spikes of CPU usage. RAM stays at normal usage levels, far from being full.

What I have tried so far that has had no effect on the appearance of the issue:

1) Disabling all extensions i have

2) Run in troubleshooting mode

2) "Create a new places database" as suggested [https://support.mozilla.org/en-US/kb/firefox-hangs-or-not-responding#w_fi...]

3) Disabled hardware acceleration

4) Creaing a new firefox user profile

5) Use "Refresh Firefox" from the troubleshooting page

6) Use the Flatpak version of firefox

7) Reinstall firefox
