Whenever I open up PDFs within the Firefox browser, they have a black background and the text and images do not appear. I can copy the text and images out of the pdf and into a word document and it works out fine. Also opening it up on other applications works out fine. Attached is what happens when I open up a known working pdf in Firefox. The browser version is the current version, 135.0.

After entering verification code from email i receive an error every time i try to login into this account on my PC, i fully cleared browser data several times but it didn't help

I used to have an image (dark, stormy sky) in my new tabs, that appeared as a background to my grid of websites (8 columns x 4 rows). Suddenly, I haven't seen it today - just noticed that it's just black. Can't seem to find where to access the different images. Would like the path to find it, or learn if it's no longer available or if I can make my own. Thanks.

After firefox update, start page changed to first photo i added here, second photo is how it was before, is there any way to get it back? Before update i had version 131.0b9, now its 136.0b1

With normal mice, when you scroll you typically scoll in steps which you feel as the mouse wheel feedback.

The issue here is with high resolution scroll wheels, whether that is a knob or a "frictionless" mouse wheel like on higher end logitech mice.

What happens: You slowly rotate the scroll wheel while nothing is happens in firefox, then you get to a certain point and firefox scolls one step, then you continue to slowly rotate the wheel, and eventually firefox scrolls another step.

What should happen: It continuously scolls as you rotate the wheel. This works in chromium browsers and other chromium based apps like discord, steam, etc, it also works in kde settings app, dolphin, okular, etc. But not firefox. It even works in terminal.

Both firefox and thunderbird are like this.

Is there a way to get this working or is it simply not supported in firefox? If so then feature request: get high res scoll wheels to work

I turned on my PC after a long time, and it seems something about firefox has changed in the way I don't like. The logo to the extreme left of the address bar which shows "This time search with" options on left-click is annoying to the eye. Picture attached below. Is there anyway you can remove/disable that logo with about://config or anything else.

Using latest version of Firefox on linux.

Hi,

I'm having an issue with Firefox (on CachyOS, but i'm pretty sure that is not relevant) when I try to hit domain with PORT number.

To be clear, I have a "service" I am locally hosting on a more widely available "domain.com" (those are examples of course...) I am using this typology to still be able to generate Let's Encrypt certs for domains (that I own) not accessible outside my network for those sub-domains, and am using therefore Pi-hole to serve the few IPs of my few "service123.domain.com"

When I use a Chromium based browser (or FF ESR v128) the only DNS query is for "https://service.domain.com:8000" is "service.domain.com" (as seen on pihole queries and in FF-ESR/Chromium DNS cache), whereas FF 135 there is first a "service.domain.com" (righfully answered by my local DNS), and then a second query "_8000._https.service.domain.com" is sent, but my pihole doesn't seem to recognize (and shouldn't have to interpret anything concerning ports), so it sends it to upstream DNS (which are unable to answer)

I have disabled DoH, and every extensions. So I am really lost on what as changed in FF that would explain this, or if it's a pihole config problem (weirdly only affecting FF 135+ ...)

Feel free to ask anything, I may have omitted important info. Thanks in advance

I recently updated my MacBook Pro to the latest MacOS (Sequoia). Though I didn't notice it immediately, today when I opened Firefox, all text is displayed in a foreign character set. It is pervasive - I've tried to use several tutorials to reset the language and all settings to default, but so far nothing has worked. I've uninstalled Firefox using AppCleaner (which gets any leftover files in OS folders, as well as the app itself), but a clean install results in the same issue. I've disabled all add-ons and reset all settings to default as near as I can tell. The only time the browser displays properly is when it's in Safe Mode. I'm not sure if this is related to the OS update, but I can't seem to identify any other recent change that could have the potential to cause this problem. Any suggestions would be greatly appreciated.

I updated my desktop browser today and now there is an expandable sidebar at the left margin of the window showing tool icons for Tabs from other devices, History and Customize sidebar. I can see how to remove tool icons and how to expand or collapse sidebar but can I remove the sidebar completely? Is this an option? I prefer the old look with the browser web page content extending all the way to the left of the screen, without the narrow vertical sidebar.

It looks like some sites are not working properly, two examples I can give are google sheets&docs, in the attached image you can see my sheets are not being shown, note that if I directly access a sheet's link it does open.

The second example is some websites with media players just load infinitely (YouTube works).

Also added network tab non 200 status code requests images.

Things I've tried:

• Disabled "network.dns.disablePrefetch".
• Tried troubleshoot mode(meaning those requests that were blocked by ublock are not the problem).
• Deleted history including cookies.
• Private Browsing.
• User Agent masking
• Reinstalling

About a week ago, I started having these problems with FF 136.0 (64-bit) on Windows 10:

• Gmail (mail.google.com) became completely inaccessible
• Google Maps (maps.google.com) opens normally, but app icons stopped displaying correctly (as in attached screenshot)

Comments:

• Gmail and Google Maps are accessible normally on Chrome and Edge
• YouTube (which is another Google product) works fine on my FF
• Tried refreshing FF then tried clearing all cookies, caches, and browsing history, but made no improvement of any kind.

Any advice?

Hi All,

I would like to hide the "New Tab to Right" option on the Tab Context Menu, and also remove the separator line right below that menu item.

The first line in the following code removes the Menu Item, but none of the 4 remaining lines succeed in removing the separator line. It remains at the top of the menu (see attached image).

Could anyone suggest some code to also remove the separator line at the top?

This is in FF 135.

Thank you.

#context_openANewTab,
#context_openANewTab + menuseparator,
#context_openANewTab_separator,
#context_reloadTab_separator,
#context_reloadTab + menuseparator::before {
   display: none !important;
}

This code below removes the first menu item and ALL separators from ALL menus, which is "ok" but not optimal.

menuseparator,
#context_openANewTab {
   display: none !important;
}

This solution provided by cor-el a few years ago appears to no longer work (the separator remains): https://support.mozilla.org/nl/questions/1340761

I updated to version 133 today and was confronted with the vertical tab bar. I did not ask for this or want it, and now I can't get rid of the side bar, in fact I seem to have just made it worse / wider. How can I get rid of this (and block it) It is just taling up space on my screen. Please help.

I am running Windows 11, with Firefox 97.0 ("Up To Date"), but the installer for the new 115 ESR does not work.

The installer (Firefox Setup 115.18.0.esr.exe) seems to think that my system is running Windows 7 and does not proceed.

I searched the forums and found a few similar entries but i couldn't see any solution so far. Whenever i try to open my inbox the page initially loads and shows the progress bar but after the progress hits 100% it just hangs there and nothing happens. See screenshot please. Gmail works normally in other browser (MS Edge) and my Android phone. I've been experiencing this issue for more than a month now. Not sure exactly when it started. Probably with v134. Installing v135 fresh didn't change anything. This is one of the most persistent issues i've experienced about browsers. I use Avast AV but all browser modules are disabled + web shield disabled.

So far i tried these steps to no avail: - Clear cache and history - Clear whole site data by using "forget site" feature - Clear cache and cookies using the padlock icon next to the search bar - Disable/enable hardware acceleration - Disable/enable javascript (gmail requires javascript to work anyways) - Disabled all add ons/extensions, tried safe mode - Reinstalled firefox after uninstalling and deleting any left over folders

My system specs: - Windows 10 pro 22h2 x64 - ASrock B450M HDV R4 Mainboard - AMD Ryzen R5 3600X CPU - AMD RX 6600 GPU - 16 GB DDR4 3000 RAM, 250 GB M2 SSD

After briefly succumbing to the ToS hysteria, I decided to switch to Librewolf. It took a while, but I got logged into sync, set up my extensions and copied over my cookie exceptions and custom CSS.

Some of the data that came over from Firefox sync seemed very wrong or out of date, most notably the settings for container tabs. No big deal I thought. I'll just manually edit the discrepancies. Once I had everything set up the way I like it, I looked up a guide on how to sync my current configuration with the cloud and followed the steps.

Phew. Time to watch some YouTube to relax. Problem is that when I finished a video and tried to watch another video, I was logged out and my site settings had reverted to default. I figured the cookie settings were wrong, so I went to the settings page and saw the behaviour outlined in the video I posted.

I've been trying to get this working for over a day now. I've tried resetting Firefox, creating new profiles and doing a clean re-install using "Geek Uninstaller" to make sure everything is removed first. I've tried 3 different forks of Firefox and all 3 of them do the same thing. After I re-install everything, I open the browser and the first thing I do is go to the settings but it's still doing the thing I showed in the video.

The fact that the data on my Firefox Sync is so old has me wondering. Why won't the cloud data update itself anymore? Based on the state of my containers, the Sync data is more than a year out of date. Could there be something wrong with that data that broke my browser when it downloaded?

I'm going to try and get hold of another computer later and try syncing to that to see if it breaks that browser too. I'll update this post when I know more.

Thanks for reading all this.

P.S. I'm typing this using Edge because my Firefox is so badly broken.

Hello,

For a few days now I've been unable to use Google tools via Firefox (I can't tell if this is due to an update or not).

As soon as a document (usually an editable or navigable area) is opened on the page, it appears completely black. Interactions work correctly at first glance (it's possible to click, write, interact with content that isn't displayed. The problem seems to be purely visual.

I've encountered the problem in all Google Sheet or Docs documents (including when I'm making a new one) and on Google Maps, regardless of location (in the case of Google maps, a notable point is that the map is displayed and then turns black after one or two seconds).

I don't have this problem on another browser, I have it in PM.

Do you have any ideas on how to find the cause and fix the problem?

Have a nice day!
