I looked at "Relay" to protect tracking. Before I knew it, I clicked and it said free. I added it and then a charge came up. Very disappointed in these used car dealer tactics. Why don't you tell someone up front if there is a charge for an add on? I may be looking for a new browser. I am not happy with Mozilla for the first time since subscribing.

On Firefox for Windows the touch and pen logic is a mess. When I hover over something with the pen or scroll using touch, Firefox seems to make both elements hover and triggers even JavaScript related code at very high rate. These 2 elements are where the real mouse/cursor is on the screen and where the currently touching or hovering over element is. For example rest your mouse on the YouTube HTML5 player, then use a pen to hover over the browsers close button or even just something else on the web page like the like button. This will ramp up the CPU and make both the player and the like button your are hovering flicker between ::hover and ::normal. This will also call lot's of instances of these related events in the website's JavaScript. Another semi-related issue is when using the F12 developer tools in "Device Simulation" mode, It's impossible to for some reason because Firefox fakes real touch injections into the OS (and they show up as if I touched the screen by the OS) which cancels the precision touchpad input movement until I lift my finger from the touchpad. This is specifically a "Windows Precision Touchpad" issue, and There is no known fix to this apart from not using a such a touchpad... On old 10+ year old laptops with PS/2 or proprietary Touchpads that report themselves as a normal Mouse this issue won't occour but Firefox will still input system-wide touch input. As a developer myself this seems very silly because you own the source code and could solve this way more elegantly than asking the OS to input Touch events... Let me know if you need anything else, and point me out where the source for the input (specifically for touch and pen) live so I can take a look at it and make some improvements. Thanks

I am using Firefox for Windows (and Android and IOS) on multiple machines. Copy to clipboard works fine on all platforms except on Microsoft Surface 5 laptop running Firefox 128 (and now 129). I have tried re-installing, re-installing from MS store, refreshing, starting in troubleshooting mode, refreshing, deleting all user profile data and create a new profile etc. with no joy.

I can select text from the address bar, or the search bar, or from within a website; the option is there to copy (I tested CTRL-C, as well as right click and choose copy), but nothing is actually getting copied to the clipboard.

Any help would be appreciated.

Hi, I tried to search to embed firefox browser in java swing application in version 1.8 of openjdk but could not find any working link. Could I get some help on this please. My use case is that I have a button called 'open link'. On click on this button, I want to open a URL in new popup or window of application and this window will be stcky, i.e., untill this window with the browser is closed, user will not be able to interact with the previous application window (main application window).

My Windows 10 system is very slow on startup. Applications are taking a long time to even respond to clicking icons, but eventually start. In Task Manager, I see that several instances of Firefox are running at startup, although it doesn't appear in the startup list. When I end these Firefox processes, the system immediately resumes normal operating speed, and things that are waiting to open appear (Speccy, CC, AV's, mail client,etc.). How do I stop Firefox from running in the background without permission at startup?

Mozilla tab keeps crashing (especially at YouTube) I was wondering if someone can help me find out why!

like tell me how to show the log or something to identify what is doing the crash.

Thank you in advance!

I often run into issues with PDFs in Firefox Linux. They either appear totally blank (typically after suspend/restore), or they appear with the desktop background showing through (as in the attached screenshot).

Hard refreshing the page doesn't change anything, opening a new tab and opening the PDF again doesn't change anything, opening a new window and loading the PDF doesn't change anything.

The screenshot is with this PDF: https://www.sgsw.ch/home/strom/_jcr_content/Par/sgsw_accordion_list_1838160259/AccordionListPar/sgsw_accordion_12353/AccordionPar/sgsw_downloadlist/DownloadListPar/sgsw_download_1049323524.ocFile/2023-08-31%20Mitteilung%20Elcom%20Erh%C3%B6hung%20Elektrizit%C3%A4tspreise%20f%C3%BCr%20das%20Jahr%202024.pdf

It renders correctly in Chromium.

Firefox 126.0 using the recommended performance settings on Mint 21.3, nvidia quadro p620 using the official nvidia drivers v535.171.04-0ubuntu0.22.04.1

I don't think you can help at this point. I followed the prompt to update Firefox and got the message that the platform version '128.0' is not compatible with min version>=128.0 or max version<=128.0. After following the instructions to uninstall then re-install Firefox, and even with the aid of a tech, I now have lost 90% of my bookmarks. Disappointed and not happy with Firefox at this point. I guess it's a done deal now and I just start over. Fortunately, I didn't have super important things bookmarked.
