When I am actually signed into the Yahoo account where the article is located. Could be politics, music, etc. I cleared the cache, etc...still stuck in the mud. please help. Thank you. raphael

I have a somewhat elderly version of Linux, which I cannot upgrade for a variety of reasons, using FF-55.0.3, which is "plugged in" to all the local audio-video libraries, but also runs a current Mozilla-128.0.3 binary, which cannot access those libraries. I use both on a regulat basis. Recently "55" lost history tracking and cannot make new bookmarks (however old boolmarks are still present). How can i restore 55's ability to track history and make new bookmarks without losing what's there? Is there a relevant variable or two in about:config I can reset?

This is pretty much the same as https://support.mozilla.org/en-US/questions/801343 back in Firefox 3.x → 4 times. I do recall having the same problem then, and disabling hardware acceleration did fix it back then, but it no longer does.

I’m currently on 115.3 ESR, but I’ve observed this for a while in Quantum (I don’t recall seeing it on Gecko with HW accel disabled).

Firefox 128; Operating System: Kubuntu 22.04 KDE Plasma Version: 5.24.7 KDE Frameworks Version: 5.92.0

In Chrome I get this error:

   PHP Notice: Undefined variable: fieldanme in D:\inetpub\webcontent\Admin\dealWorksheet\print.wip.php on line 747
   PHP Notice: Undefined index: in D:\inetpub\webcontent\Admin\dealWorksheet\print.wip.php on line 747

In Firefox I get:

   File not found
   Firefox can’t find the file at https://the_url_in_question.
   Check the file name for capitalization or other typing errors.
   Check to see if the file was moved, renamed or deleted.            

Same file called seconds apart. Please note: this is NOT a 404 error. The file is there: if I fix the error on line 747, the PHP Notice goes away and FF loads the page correctly.

Is there a way to force FF to use HTTP/3? There are multiple instances (youtube, for example) when site says "alt-svc: h3", but FF ignores it and keeps using at best HTTP/2.

I use a 3rd party password manager that has a Firefox browser extension. Using usernames and passwords is no problem. But for sites that I have passkeys saved for, Firefox tries to intercept the passkey request and validate the request on it's own. If I go into about:config and set security.webauthn.enable_macos_passkeys to False, the passkey request is just not accepted at all and the login request errors out.

I need the browser to be able to pass these passkey requests to my extension based password manager, not to be interpreted by Firefox itself.

The requested functionality works fine in Chrome and Chromium variants such as Edge and Brave, btw.

In seeing other answers to this dilemma it presents another problem. I do use sync. But what troubles me is IF I need to give out the password for someone to use the internet that person now has access to my passwords. Since there seems no way, unless I shutoff sync. Is this correct? Should there be some Secondary password? Passwordpasswordpasswordpasswordetc.

Hi, guys! This is driving me crazy! PLEASE, HELP!

Here, both Google Docs and .pdf files (from any site) keep jumping pages while I'm reading.

For example, from page 2, it goes to 9, then I scroll back up and it's on 15, etc.

I've already tried deleting all cookies, clearing the cache, completely uninstalling Firefox from my PC, but it always happens. I'm having this issue for weeks.

I tried uninstalling extensions, but I can't solve it. It's a nightmare.

Hello

Out of nowhere I started having problems watching Videos on Twitch. So, after some Flatpak repairs and reinstalls, I decided to sync my data with Firefox Sync and remove it completely. For my surprise after reinstalling and logging in on Firefox Sync my only extensions and, what looks like part of my history were restored. Lost my session, custom tabs names etc.

I'm using openSUSE Tumbleweed and KDE Plasma. Ever since I updated to Plasma 6.1, Firefox crashes constantly when using Wayland. I'm not having this problem if I'm using X11. Crash reports are sent after every crash so I'm sure someone can reference these. When starting Firefox from a console, I got this message after a crash: "[GFX1-]: Wayland protocol error: wp_linux_drm_syncobj_surface_v1#67: error 5: explicit sync is used, but no release point is set"

Will this get fixed with the next Firefox update? Currently using 127.0.

Hi everyone,

I use Firefox as my primary browser for several reasons, but the main one is because it has the best Picture-in-Picture (PiP) feature. However, I no longer use Windows and have encountered problems with it on various Linux distributions (Ubuntu, Fedora, Debian...). Currently, I'm only using Fedora 40, and the problem persists.

The issue is that when I click on the PiP icon, it activates normally, but when I switch windows or minimize and then maximize Firefox again, the video disappears.

I will attach some screenshots to clarify the issue.

I would like to know if there is any way to resolve this. I’ve already reset the settings, cleared the cache, and tested different installation methods (software store, .tar.bz file, apt, dnf, snap). I’ve tried troubleshooting mode and even installed the Developer Edition, but the problem persists. I’m wondering if this is an issue with the Linux version of Firefox.

Thank you.

I open PDF from my files system or an app (Zotero f.e.). I make annotations since the annotation tools in Firefox are nice. Just a few highlights, maybe comment, underlines, whatever. I want to save the file and quit Firefox.

BUT - Firefox doesn't automatically save the opened file but rather wants me to "save as" a new file to be downloaded and chosen to be saved somewhere specificaly. I cannot just "save", I have to "save as" like I would download or create a new file.

I don't want to create new downloaded file to save somewhere else. I want to save annotations and such changes directly to the original file so I can just hop in and out of the file when I want to continue reading or edit annotations f.e..

MS Edge let's you save the changes to the file right to the original file so you can just hit "save" (ctrl+s) and close the window.

Hopefuly my question for clarification is somewhat understandable.

Thank you for your time

Hi,

I installed thunderbird in a new computer via flatpak. The computer is running PopOS 22.04 and the current Thunderbird version is 128.0esr.

I don't know if this happened after the last update from 127 to 128 or was like this before, but on the compose window all the menus and buttons on the top row are completeley invisible, white on white (if I hover over them, then they are slightly visible). See the first 2 images.

The main window is OK and everything is readable (see 3rd image).

I don't know how to change these colors.

Any help will be appreciated.

I am using Firefox 128.0 on Fedora 40. Whenever i am playing a youtube video its saying "An error occurred. Please try again later. (Playback ID: YfAmDqxb_Y3iWVfB) Learn More" I have no issue with ad blocking add-ons because i have Youtube Premium, so hopefully that's not an issue. I have tried few solutions from the forum , which were :

1. Unchecking "Use hardware acceleration"  Under Performance tab in Firefox
2. Using firefox safe mode
3. Refreshing Firefox
4. Deleting my cache/history
5. Enabling "Widevine Content Decryption Module provided by Google Inc." in my addons

But still i am having the same issue, its been 2 days, I am unable to find an appropriate solution to this. Kindly help me regarding this.

The integrated webcam (IMC Networks Integrated Camera, according to lsusb) on my linux laptop does not work in firefox (v124). It works in desktop apps (eg webcamoid), and chromium. I've checked the permissions (about:preferences#privacy), and that is not the problem. about:support does not list the device in the input at all. I've tried using LD_PRELOAD=/usr/lib64/libv4l/libv4l1compat.so, but that has not helped. Does anyone have any suggestions?
