It takes an extremely long time for documents (e.g., PDFs) to print when I print them from Firefox (compared to printing from the built-in Preview app). How can I resolve this so that I can print documents directly from Firefox without this long delay?

Browser: Firefox 105.0.1 OS: macOS 12.6 Installed Addons: 7TV, BetterTTV, Facebook Container, FrankerFaceZ, Merge Windows, Tab Auto Refresh, TWP - Translate Web Pages, uBlock Origin

I have recently installed Linux Mint and it came with Firefox out of the box, and I decided to try it out, but I can't, for the life of me find a way to transfer my Opera passwords there. I do have Opera installed right now.

Any advice returned by Google seems to be obsolete or only worked perhaps in older versions of Firefox. The main idea of using userChrome.css to override the default styles for Reader View does not seem to work. My userChrome.css file does work on other items though (like removing the sidebar width restriction).

Whatever advice I find via Google perhaps cites outdated CSS selectors, but current selectors do not seem to be documented anywhere by Mozilla. Moreover, I cannot find any file on my local drive named aboutReader.css when using find or grep commands in bash, those this file name is alluded to when viewing a page in Reader View and then in turn viewing source on that transformed page.

Moreover, addons that would allow me to change the colors seem to be restricted in Reader View.

It does seem like something has changed in recent Firefox updates but I can't remember when I last saw, for instance, links in dark mode Reader View that were still pink (whereas now they are blue, and impossibly dark to see, especially when you are disabling as much blue light as possible through your operating system). I need a higher contrast color for links in dark mode Reader View so I can actually see them.

I can alternatively use the Tranquility Reader addon and have custom colors, but A) that addon does not work with the Automatic Reader View addon, whereby I can always have various sites appear in some sort of "reader view" whether the native one or Tranquility Reader, and B) hitting refresh when in Reader View will defeat some soft paywalls but this does not work with, e.g., Tranquility Reader, so I still would prefer to be able to custom colors in the native Reader View feature, rather than rely on an addon.

1. Where are the current styles for Reader View even documented? 2. Is overriding them now restricted? 3. Why did the link color change from pink to blue in newer versions of Firefox (this is a terrible accessibility bug)? 4 .Where is the alluded to aboutReader.css stylesheet actually stored on my computer (it doesn't seem to be a file on the filesystem in the Firefox profiles folder, it seems more like it is embedded in the Firefox binary/executable)? 5. Will Firefox settings ever allow us to set colors specifically for Reader View (I don't mean the override settings for all web pages, particularly web pages not being rendered in Reader View ... that setting does not help in Reader View, nor would it be the desired preference for pages not in Reader View)?

Thank you.

The URL in the URL bar is trimmed. I went to about:config and disabled "browser.urlbar.trimURLs", but it still did not work after I restarted Firefox. (see images)

Firefox version: 105.0 (on beta update channel)

I later then found out that there is a lot of unused space on the right. (see https://1drv.ms/v/s!Ag9_47ED3j7sgsZhkB02k7gI3lavyg) How do I remove / make use of the space on the right of the URL bar? How do I turn off the trimming of the URL?

Any help is appreciated!

Anyone can give me a hint how to get rid of the frames around the pictures/shortcuts on the new tab page?

As far as I can tell, this has something to do with Firefox aggressively offloading stuff from memory to storage. When I alt-tab at times, Firefox completely freezes. Every Firefox window hangs on a single image and I am unable to interact with anything for a few seconds. During these seconds, I can see the memory % in the Windows Task Manager slowly climbing until Firefox unfreezes itself, so it seems to be loading stuff back into memory. For example, it'll climb from 55% to 70%, taking its sweet sweet time. I also see some disk usage with 'System' during this time.

This behavior occurs even when I'm active on the browser and at 50% memory. It seems to occur more often once I hit the 60% memory mark.

I'm almost certain that this is a Firefox-specific issue, because I can interact with any other program during this period. It is only Firefox that stops dead in its track.

Is there a way to make this behavior less aggressive? I'd rather not have my alt-tabs freeze every few minutes.

Ever since yesterday, scroll click (I use it to scroll through websites) has stopped working in Firefox. Works in in programs, other browsers, etc., just not Firefox.

Whats weird is it still registers a click when I use it, so I can lick on links with it if I want, but the function of scrolling, either by clicking once and using my mouse to go up and down, or by clicking an holding, no longer works.

I've tried disabling add-ons, incognito mode, nothing seems to work.

When refreshing and clearing cache using CTRL+Shift+R, browser should reload all assets. However when refreshing site with @import(ed) style sheet, it does not update.

The workaround is to open the style sheet in a new tab (e.g. https://my.web.com/assets/custom.css) and run refresh + clear cache there CTRL+Shift+R, which loads the updated style sheet.

Then, upon refreshing the original site (https://my.web.com), the CSS has been updated.

Is this a bug or expected behaviour?

I'm currently attempting to try out userChrome.css customization, but my profiles folder doesn't exist (I'm on windows 10). Trying to open the folder gets me the message that "[Folder name] is unavailable," and when I try to navigate there by getting to the appdata\roaming folder, there just isn't a Mozilla folder at all.

I've already tried a few things, specifically:

- making an account via typing firefox.eve -p into the windows + r folder
- I've never deleted anything from the appdata roaming folder, so I wouldn't have accidentally deleted it
- restarting my computer (+ updating windows)
- reinstalling firefox

I did attempt to show hidden file extensions in windows as well. Admittedly I'm not entirely sure if that worked, but it was something I tried. I've also attached images of my appdata roaming folder (the section of it which should have a mozilla folder), and a pic of the message I get when I try to open the folder.

Any help would be appreciated!

Amazon Sign-in problem started on 10-15-22. Amazon does not accept my password and asks me if I would like to receive a text message for verification. There is no yes or no selection displayed. I select resend text and I am given a telephone number for Amazon customer service. I go thru a 15 minute security verification process and Amazon tells me if I do not answer any questions correctly, they will cancel my account. On the 2nd time I contacted Amazon, I was told to use Crome browser and not to use Firefox.

This problem happens with my personal computer (windows 10) only. My Android phone using the Amazon app works with no problems. I can also use Crome browser on my computer and Amazon works fine.

Any suggestions ? Thanks

In the past, I have not had problems logging into PayPal via Firefox on Windows.

Today, I can get to www.paypal.com but when I try to log in (takes me to https://www.paypal.com/us/signin), my browser window just shows the circling image.

When I tried another browser (Chrome) I got to the login just fine. My Firefox is up to date (105.0.3)

What changed to give this issue and how can one resolve it?

OK, I have read (ad nauseum) every Fix to not getting sound while using Firefox. I disabled Hardware accelerated Graphics, Cleared cache, cleared history, disabled all addons, updated Firefox, uninstalled and reinstalled Firefox, etc. Nothing has brought the sound back.

I have sound on my computer and on games and in Google Chrome and Microsoft Edge but not Firefox. Anyone know something that I may be missing? PLEASE HELP! I wish Mozilla had Tech Support! :(

When I go to https://outlook.live.com/owa/ and click on Sign In, I am sent to https://login.live.com/login.srf?wa=wsignin1.0&rpsnv=13&ct=1664586249&rver=7.0.6737.0&wp=MBI_SSL&wreply=https%3a%2f%2foutlook.live.com%2fowa%2f%3fnlp%3d1%26RpsCsrfState%3d17ece2a1-03ee-4d23-1804-181c6fe01157&id=292841&aadredir=1&CBCXT=out&lw=1&fl=dob%2cflname%2cwld&cobrandid=90015 which stays blank instead of bringing up the Sign In form. I've tried deleting the cookies to no avail. I've tried Troubleshooting Mode to no avail. It's been this way for a couple of months now. I have no trouble signing on to Outlook.com using other browsers.

When expanding any video to full screen mode, the video does not occupy the entire screen. However, if Firefox itself is in full screen mode, then the video will occupy the full screen.

I tested this on YouTube and another website's video player and was able to consistently replicate the issue.

Zoomed in zoomed out, adjust font sizes Either it's way too tiny to read or the page is fine but text over laps i've tried the zoom in on text only as well Basically tried everything. enclosing a youtube page for reference

Hi Firefox community,

Do we have any settings in firefox where we can enable/disable dark mode in firefox browser instead of installing a plugin or addon? I am looking something that is offered within the browser instead of a plugin.

Thank you all.

I am able to find the mailto setting easily. However, there are no clients listed to choose from, no gmail, yahoo, nothing. If I click "choose other" I'm expected to choose an application from my computer. I just want to be able to click a mailto link and have it go out through a new tab via my existing, free, yahoo mail account.

While exploring about pages in Firefox, I came across about:profiling. I'm not sure what exactly it does, but since I've been to it, a profiler icon has been added to the toolbar and I can't find any way to get rid of it completely (only ways are to hide it). If it could be added, there must also be a way to remove it? How can I close it?

HELLO very small cursor on Firefox windows (on all other windows the cursor size is normal) via snap after upgrading to ubuntu 22.04.1 LTS. how can i change it? Thank you
