Firefox supportforum

When I copy text from other websites, I'm not able to paste in the text field of Whatsapp Web. I'm using Firefox Developer Edition Browser in my laptop. But when I copy text from Whatsapp Web itself, I am able to paste in the text field.

This issue started happening just a few days ago.

Here are my specifications:

Browser: Firefox Developer Edition 117.0b8 (64-bit)

OS: Pop!_OS 21.10

Firefox crashes (tested in troubleshoot mode) for this URL : Link which causes crash https://developers.google.com/android/guides/opensource#java

There are no crash logs generated either (checked in about:crashes) . Attaching a post-crash dialog screenshot

A lot of the images appear broken, see the images attached(left is FireFox, right is Chrome) Only happens with Mozilla browsers, nighty, beta, regular, I've tried them all Reinstalled countless times Hope that someone will help me with this

I developed a web app that checks the existing session login for each new page. So, after logging in the first time, the user is shown a dashboard with a list of functions they can access (My Account, etc). When an item is clicked and the application calls the function, it first checks for the existence of login session. If it's not there, then the user is forced back to login screen. However Firefox is deleting the session at some point so when the session is checked for the new function, the user is forced to login again. Chrome, Safari, Edge do not and are fine.

Enhanced tracking is turned off for the site and is shown as an exception. What is happening and how can prevent it?

I use HTML files to create images for a tile based game we play. 6 months ago I was able to create a table with collapsed borders and 0px padding, margins, and borders, then draw my image with 207 x 207 JPEG TDs in multiple TR rows, then place another GIF image over all the JPEGs with transparent edges. Doing this for a table that was 6 tiles (207px) wide and 4 tiles deep, at ctrl 0, displayed a Firefox combined image that was exactly 1242px x 828px that was completely visible on 24 inch 1920 x 1080 DELL monitor. This allowed me to right click an empty space on my Firefox screen and select Take Screenshot to click on the GIF overlay image and capture that image with all of the tiles that were behind its transparent edges.

For some reason, I have no idea why, my 207px by 207px tile images are now being displayed as 282px by 282px at ctrl 0, and the overall image is now too large to fit on the screen, so taking a screenshot of the proper sized image is no longer possible. For example, at ctrl- ctrl-, the tile images are 221 pixels square, which should be 1326 pixels wide for 6 tiles, but my 1242px wide GIF file displays at 1330 pixels wide, probably due to some kind of rounding error.

I was able to use about:config and change layout.css.devPixelsPerPx from -1.0 to 0.74 and it did solve the problem. But it does so with a lot of warning for changing that default value!

So my question is simple: how does Firefox, on Windows 10, determine its screen pixel to Image px relationship? I need to know what to look at for the proper way to get my px to pixel ratio back to 1 to 1.

This is what the working image looks like while designing the center scoreboard tile https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2022-08-23-13-36-34-2fa67f.png

and this is what the final image looks like when you take a screenshot of the image https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2022-08-23-13-36-53-beae42.png

Firefox is literally the worst browser now, im so sick of opening a new tab and seeing all these woke ass news on the homepage/ads. uninstalling this total piece of trash, if you use firefox you are [derogatory]

Tell me how to reduce the size of buttons, tabs, and everything else BUT the fonts in my browsers. All of them have been affected. I've exhausted all of the normal "look in Settings and use your brain" options.

I had set up a userContent.css file in the past to pull up and fetch an image on my computer to display as a background on the homepage. It worked and did it's job until recently, when I had recently relocated a lot of my files around on my computer. I have redirected everything to where I want it to look, including the userContent.css file to the new location for the image I want as the background. Firefox loads the .css file correctly, and recognizes the file existing, but it won't load the image itself for some odd reason. It states it "may not load or link the file" because of a security error, and thus, can't load the image. I never had to deal with this before. How can I get Firefox to be able to load my image like I want it to? I have screenshots that I can provide, but this site doesn't want to upload them at the moment.

Hello.

It seems I get a problem or two almost always with a new update lately. I have been using an userChrome.css to reduce the width of sidebar but the latest version 107.0 now ignores it and have a wide width even at the narrowest. Mine currently is set as, "#sidebar {min-width:30px !important; max-width:none !important;}" This no longer works. Your support much appreciated.

Regards,

I first realized an issue with downloading PDFs through the Firefox viewer - I cannot. The download button does nothing, there is no prompt, no popup, and no file downloaded. I have also tried to print to pdf, that also seems to fail.

Today I realized I also cannot attach any files to an email through Gmail in Firefox, which is now leading me to believe that the software is unable to interface with my files at all.

Things I've tried include: - Turning off popup blocker - Refreshing Firefox in the ->Help->More Troubleshooting Information Menu - Starting Firefox in safe mode - Reinstalling through snap

The only way I can currently download files is through wget, and the only way I can send attachments is by installing Google Chrome, which is kind of a last resort for me.

I am running Ubuntu 22.04, this is on Firefox 106.0, though it didn't work last update either.

Thanks for any help

Edit: I have been googling for answers but after posting this question a similar thread popped up, the solution is to install the following packages:

xdg-desktop-portal xdg-desktop-portal-gtk

Hi Today I updated Firefox to version 106.0 and I can't get rid of the "arrow button" from top right (screenshot attached - near the minimize button, I marked it). The function of this button is clear for me - tabs management. But I can manage my tabs without special button for it. I want to remove it. I tried right clicking on it, but the "remove from toolbar" option is unavailable. I tried to customize toolbar, but it won't work either (I can't take it from te toolbar).

How to remove this button?

Over the last five hours, I have gotten 27 emails from Firefox Monitor for this data breach, for the same email address. I have already marked the breach as resolved in Monitor but I keep getting emails. Is there anything I can do about it?

Hi All,

I' m having the issue that .jpeg images don't zoom smaller in Firefox (they do in Safari). I'm performing cmd-+/- on a Mac keyboard.

Any ideas?

Thank you, Russ M.

In order to more convenient drag-and-drop interface, I need a fixed fixed space in nav-bar like Edge. For now we can add a flexible space on it. But it's flexible and it will disappear when I use a side window. And I can't drag over titlebar-buttonbox-container Please help me. Thanks!

Hi, after updating to 118.0+ my MX vertical binding was changed to backwards -> Responsive design mode, forewards -> nothing or turning on add-on for bitwarden. I want back next and previous page feature. How to solve it? Thank you

So I downloaded Firefox and logged in expecting my bookmarks to carry over after I "sync'd" it, however the did not. So I went to my old pc and did the export bookmarks thing and imported it to the new pc.

Now.. I have all my bookmarks and everything appears great. Except whenever I open a link from say my work it opens a Mozilla window that doesn't have my bookmarks. When I try to combine the windows It doesn't let me. I am also scared of losing access to the Mozilla with my bookmarks as I work from home using those. (the desktop shortcut to Mozilla opens the one without all my work)

In the attached screenshot things to note, the bookmark bar available on left isn't there on the right. Additionally in the taskbar (bottom) it shows Mozilla in two distinctly separate icons. When two Mozilla windows are open, they share the same icon on the taskbar, these do not, which leads me to believe I have two incompatible versions existing next to each other.

I don't know why the page https://encuestas.msssi.gob.es/limesurvey/index.php/438579?lang=es is marked as insecure in Firefox. I tried in Chrome, Edge, IE... and the page is marked as secure, the certificate is recognized.

I attach screen captures of Firefox and Edge examples.

I've the security.enterprise_roots.enabled setting enabled.

If I check for Firefox error details, I see (auto-translated to english): https://encuestas.msssi.gob.es/limesurvey/index.php/438579?lang=es The issuer of the other end's certificate is not recognized. Strict HTTP transport security: false Setting HTTP public keys: false

Hello. For a couple of months now I can't seem to be able to reproduce some videos on YouTube (depends on their format) and no videos at all on Facebook, for example. I have the same issue on both regular and dev versions. I tried many solutions from the forums but no success so far.

My OS is Linux Ubuntu 20.04. Browser and video drivers all up to date.

I use the Windows registry FontSubstitutes (Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes) to replace system fonts like Segoe UI with other fonts. It takes a lot of work to get Windows itself to respect these options, to the extent that I have to make it believe Segoe UI isn't present by modifying a different registry location (Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts).

However, Firefox does not respect the FontSubstitutes settings. Based on a previous post here, this is something it did prior to Firefox 89, but has stopped doing.

An ideal solution would be a way for Firefox to correctly read my FontSubstitutes settings. An acceptable workaround would be a way to provide Segoe UI for Firefox to use while still preventing its use in other applications. (I know that, for instance, Adobe Photoshop allows users to install fonts to Photoshop itself, bypassing the system fonts folder entirely.)
