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

When I open Firefox and call up bing maps , it starts to load the page , then Firefox crashes . Has been doing this for several firefox versions . Looking at the crash report , I always get "The debug symbols are missing for firefox. Please install firefox-dbg." but I can't find firefox-dbg to load

Hi. Randomly, but very often, I cannot drag and drop move tabs. Other moving (p.e. "move to beginning") does work. After restart of Firefox, it works again - till it randomly does not.

Current Firefox (126.0) Kubuntu Installed via Snap

Hello,

I'm developing a web application. Yesterday I could access it with http://localhost:8000, then, I implemented https and it worked too. Today I needed to use http again for my tests, but everytime I type http://localhost:8000, Firefox changes it to https://localhost:8000.

I already tried to clear everything in the history, even the cookies, but it didn't work.

What should I do?

Also, could you fix this bug? I've found articles from 5 years ago reporting this issue, but the bug hasn't been fixed yet

Firefox uses about half a gig on my disk, that's: '~/.mozilla' and '~/.cache/mozilla' can that be reduced? Either some setting that limits disk use or even a manual deletion of ancient stuff?

Tell me why google says this:

Unable to connect

An error occurred during a connection to www.googleadservices.com.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

when I click on an advert for a product provided (I assume) by google at the top of search results. I have cleared the cache and cookies. Latest firefox on ubuntu 22.

After updating to the current version of my OS(listed below) I can no longer drag a tab to detach it from the firefox window. Doing so drags a preview of the tab, but it is never separated from the current window. I can drag it to an already existing window to move tabs from one window to another, but not to create a new window from a single tab.

Looking for a fix on a right-click issue that I keep having...

When using Linux Mint (Cinnamon), the right-click context menu occasionally becomes misaligned with the cursor position. Attached image shows a right click on the text box in the right browser window triggering a popup in the left browser window.

This most frequently happens when:

• Multiple windows are open AND
• The window being right-clicked on is "snapped" into place (by dragging to the side of the screen)

Error seems to occur most frequently on windows snapped to the right-hand-side of the screen.

Context menu placement is offset by an arbitrary amount determined at time of window-snapping. E.g., moving the cursor down 1 inch in the example image below will move the menu down 1 inch as well. Un-snapping the window, and re-snapping can adjust menu-cursor-offset distance.

When I open a locally downloaded pdf in firefox, the background is displayed as what was previously displayed on that portion of the screen, and scrolling simply overlays moved text over what was previously displayed. Does not appear in screenshots. One of the images shows what the pdf looks like prior to scrolling, and one after.

I get bad request from the official Mozilla repo: Err:8 https://packages.mozilla.org/apt mozilla/main all Packages

 400  Bad Request [IP: 34.160.78.70 443]

Did the URL change or smth?

After SUSE-15.6 updated FIREFOX to 115.11.0esr, all sites show choppy videos. I have no idea why or what I can do to resolve the issue. If someone has an idea, it would be greatly appreciated

I am having problems playing a particularly demanding video from YouTube (https://youtu.be/-W_nFlIAWFM) which runs at 4K/30 fps. It is a video taken from a drone flying over the Matterhorn in Europe. Here is my configuration: 1. I have a 200Mb connection to the internet and bandwidth testing confirms that it runs at a consistent 195 - 202 Mb. 2. I am using Firefox 126.0 on a dual boot machine running Ubuntu 22.04 LTS and Windows 10 (both OSes show similar stuttering and pausing). 3. My hardware is a Gigabyte Aorus Z690i motherboard with 32 GB of RAM and an Intel i5-12600K processor and an NVidia GeFroce RTX 2060 Super graphics card. I have tried disabling "Use hardware acceleration" in Firefox and also disabling all add-ons and rebooting. This hasn't resolved the problem. When I watch the same video in Google Chrome, it seems to display a much slower frame rate than 30fps but doesn't stutter. I have concluded that this video must be a super demanding one to render. There are many picture elements changing constantly. But is there a way to watch this at 4K/30fps with it playing smoothly and at the correct frame rate?

hi, when starting firefox, it makes some connections to

   firebaseinstallations.googleapis.com
   detectportal.firefox.com
   app.adjust.com
   o1069899.ingest.sentry.io
   assets.mozilla.net
   contile.services.mozilla.com
   firefox.settings.services.mozilla.com
   incoming.telemetry.mozilla.org
   location.services.mozilla.org

without user-consent. so this is not gdpr-compliant. how can i tell firefox not to connect to these sites? thanks t.

I need to migrate the complete profile (all settings, bookmarks, passwords etc) from a snap install to an apt install on the same system. Currently I have both versions installed, but i want to remove the abomination that is snap..

I tried copying ~/snap/firefox/common/.mozilla/firefox files to ~/.mozilla/firefox but that doesnt seem to work. Since this is a multi-user system i dont want to rely on mozilla accounts to sync everything to the cloud.

What do i need to do in order to migrate all the data from one install to another?

I use DuckDuckGo for my basic search engine on both my laptop (Ubuntu system) and iPhone 8. It does not work today - saying "There was an error displaying the search results. Please try again.", needless to say...I have tried a number of times and differed the searches to no avail. I also cleared recent cache/history. Still stuck. Searching on Chrome I see on https://news.ycombinator.com/item?id=40451490 that others are also experiencing this problem and do not understand it either - just a few entries

The Sun (a rather populist newspaper in UK) has an article saying it is international and happening today, 23 May 2024, suggests no fixes. (Not exactly a reliable source in my thing)

Has anyone ideas or should I just wait and use an alternative search engine meanwhile? Thanks for any help

I need to go over the head of the Mozilla Triage manager who has left https://bugzilla.mozilla.org/show_bug.cgi?id=1406865 open without a resolution for **seven years**. How do I do that? This is a bug reported in Firefox 57 and **still** not fixed in Firefox 125. I cannot find any support category anywhere in the Mozilla website that covers appealing a decision by one of their employees. The last comment from this uncooperative indivisual is "But given we support it on macOS and Windows yeah, it seems not very objectionable." Who is this **clerk** to override the fact that a number of customers very much find this "objectionable". I cannot find anything on https://www.mozilla.org/en-US/contact/ that addresses this issue. I cannot find even a surface mail address for Mozilla. For example my complaint has nothing to do with any of the following:

   I’m having problems with using Firefox
   I want to donate to Mozilla
   I have questions about using Mozilla’s trademarks
   I’d like to report misuse of a Mozilla trademark
   I want to hold an event in a Mozilla space
   I want Mozilla to sponsor my event
   I’d like permission to use a Mozilla logo
   I’m interested in Pocket’s sponsored content on Firefox
   I’m a member of the Press and have a question for Mozilla

Yes I am having a problem with Firefox, but the clerk responsible has, through sitting on this issue for **seven years**, basically told the entire community that he doesn't give a reservoir.

In particular I feel this unacceptable behaviour should be brought to the attention of senior management, but there are no contacts for anybody in senior management.

I am trying to use a <select> tag to display a color selector. So each <option> has a background color to match its displayed text:

```<select id="strokeColor" name="strokeColor" style="width: 10em;">

             <option value="black" style="background: #000000; text: #FFFFFF">
                     black
             </option>

<option value="aqua" style="background: #00FFFF">

                     aqua
             </option>

<option value="blue" style="background: #0000FF">

                     blue
             </option>

<option value="brown" style="background: #A52A2A">

                     brown
             </option>

<option value="gray" style="background: #808080">

                     gray
             </option>

<option value="green" style="background: #00FF00">

                     green
             </option>

<option value="magenta" style="background: #FF00FF">

                     magenta
             </option>

<option value="orange" style="background: #FFA500">

                     orange
             </option>

<option value="purple" style="background: #800080">

                     purple
             </option>

<option value="red" style="background: #FF0000">

                     red
             </option>

<option value="white" style="background: #FFFFFF">

                     white
             </option>

<option value="yellow" style="background: #FFFF00">

                     yellow
             </option>

<option value="#000000" selected="" style="background: #000000">

                     #000000
             </option>
         </select>```

On Chrome this displays as expected:

https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2024-04-18-22-02-25-eebbd5.png

But on Firefox the background colors are ignored:

https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2024-04-18-22-02-35-bd90ee.png

How can I get Firefox to display the background colors?
