Firefox supportforum

I know this is an obscure question but it would save time typing it all in each time.

I would like to create a windows shortcut to launch the profile manager like so:

"C:\Program Files\Mozilla Firefox\firefox.exe -profilemanager" - but it says "the name specified in the target box is not valid. Make sure the filename and path are correct." It works fine without the -profilemanager part.

Maybe it would have to be a batch file I'm not sure.

All of a sudden, my bookmarks ( and other bookmarks) are double spaced. This just happened today and I didn't make any changes. How do I get rid of the double spacing ? Thank you.

I'm finding that Twitter is not loading in my desktop Firefox browser (89.0.1), and I'm getting the error "failedScript=polyfills". I do use an ad blocker, but it's turned off for Twitter, so I'm not sure how that could be the issue. I'm not having the same issue in Safari. Thanks for any help!

I made a payment online, & when I tried to print a receipt I got a notice that the popup was blocked. How do I unblock that? I wasn't aware that I have a block on this browser. Thanks for your help!

When I use firefox on my main display (1920x1080 144h 16:9) in full screen there is a noticeable white line in the bottom, not using full screen fixes it, but a pain in the ass to resize it all the time. I tried using the browser on my secondary smaller display (1920x1080 60h 16:9) and there is no white line. This seems to be a bug, how do i fix it?

Hello Mozilla Firefox support, Can you help with the following issue? I'd like to use Firefox as my primary browser however it presents blurry letters, particularly the smaller the letter size. I am using Windows 10 Home, Firefox Version 89.0 (64-bit)on a Surface Pro 7. The SP7 screen presents clearly, however, my external monitor, a BenQ SW Series LCD Monitor has the blurry text. Thanks in advance for help or directions to pursue in fixing this issue.

Dear Community, after one of recent Firefox updates I experience an issue with text display on certain pages. Some text is not visible because it is white on white background. The text is there, I can highlight it. I am using latest Firefox release as suggested by auto update. This white on white issue is regardless of selected Theme, even in dark theme it is white on white. Please have a look at the attached screenshots.

Hey all,

I upgraded firefox to 89.0 (firefox for ubuntu). When playing videos it now uses RDD process instead of Web Content. The problem however comes from the resources "RDD process" uses. It is consistently at 100% usage of a CPU core and this is causing my fans to be really loud. I fixed this by changing media.rdd-process.enabled to disabled in about:config and this fixed the system resource issue but I don't think this is what is meant to happen.

As far as I know "RDD process" is meant to use the GPU. My computer has a dedicated GPU so I am at a loss as to what is going on here. Anybody who has any idea?

Thanks in advance.

Hello, until yesterday, I had the video downloader helper icon on the right hand side of my top list of sites near my Firefox account icon. Now in the 89.02 version, it's gone so I can't download directly movie trailers for example. How do I put that icon back on around there? Thanks Luc

I am an older Firefox user and I often find myself enlarging and decreasing size of fonts on different websites to make them readable. Lately I notice I am having trouble with the fonts I am using so I need advice. What are the good fonts to use for Firefox? Also, what is the setting to adjust the fonts Firefox uses in the toolbars and address bar?

I am currently using as follows: Default: MIcrosoft Sans Serif (I like the clean lines of a sans serif, but I'm not wedded to any particular one. ) Size: 10 Proportional: Sans Serif Serif: Newsreader Sans Serif: MIcrosoft Sans Serif Monospace: Lucida Sans Font size: 10 Minimum size: 9

The problem I am having is that text in the address bar is often unreadable due to artifacts that look like a digital font, you know, the blocks? If I highlight the URL inside, the artifacts clear up. I reinstalled Firefox but that problem didn't go away. I need to know which font Firefox uses for that area before I can even begin to try to fix it. Any font suggestions are also welcome. I particularly would like fonts that are readable in many sizes and free of flourishes.

By the way, I chose the image of Google News because I also have trouble with alt text showing, I can't figure out how to get rid of that so any ideas are welcome. It's just Google.

I cannot access to Facebook or Messenger on Firefox, when i open, Firefox said Secure Connection Failed. I got this error for a week,i have used Edge and Facebook still work,pls help me.

I went to clear my recent history, but it will not do so. Then I went to Menu, Settings, Privacy and Security, Cookies and Site Data, Clear Data. No change. I tried do a Refresh installation. No change. I exported my bookmarks to my hard drive, and uninstalled Firefox. I downloaded a fresh install of Firefox, and installed it. ALL MY BOOKMARKS AND SETTINGS ARE STILL THERE!! Still won't allow me to clear History. Whatever happened, happened less than 24 hours ago, going by the websites showing in Recent History. Can you advise me?

Every solution which I have found for Firefox 89 "Proton" so far which moves the Tabs Bar below the Navigation Bar (AKA "address bar"), with the Menu Bar above it, does NOT move the Tabs Bar below the Bookmarks Bar. The Bookmarks Bar appears to be overwritten and blank, and occupies space below the Menu Bar, Navigation Bar, and Tabs Bar. This empty space separates the three bars which are implemented and the content of the currently-selected tab below it.

Currently, my userChrome.css file is a copy posted by Cor-el (?):

Evidently, the text editor for this website does several things to the above original text that, frankly, seem unnecessary and undesirable. The .CSS file is just an unformatted text file, so what is the problem with simply copying its contents and pasting it in to the body of this post?

Which is also to say that I do NOT have a clue as to what any line in the file is meant to do, what effect it has, why it is even in the file at all, or why it is written in the way that it is. So DO NOT tell me that I "CAN" create a Cascading Style Sheet on my own when I cannot even modify one that has been provided.

On the face of it, something is missing from the above CSS text. What change needs to be made to the above content so that the Bookmark Bar will appear between the Navigation Bar and the Tabs Bar??

Thank-you very much for your time and attention to this request for assistance.

I open the terminal (I'm using FreeBSD) and I run: `firefox --help` and I get a lot of command line options. However there seems to be no way to simply get the user agent string. This is kind of annoying because I might want to plug the current version of my Firefox browser in some automated scripts. At the moment I need to open Firefox, then go to the console and type in: `window.navigator.userAgent` copy the string manually and paste it wherever I want to use it. It would be really nice if there could be an extra option to the `firefox` command, like: `firefox --user-agent` that prints this information in the console. Maybe there's a way, if it is it must be really hidden because I couldn't find relevant information on how to do it.

Kind regards, Lucas.

I used to use a lot the three dots next to a webpage to share the page via airdrop (to have it/share it with my own phone or others'). Now the three dots have disappeared and, although I read here that I could do that by right clicking the page, the option for SHARE does not appear. Can you please explain how to do this now? (I use a Mac).

When trying to play any video on udemy.com, I get the following error message. "Firefox is installing components needed to play the audio or video on this page. Please try again later." Youtube videos work fine, I've tried troubleshoot mode and I've restarted my PC. Firefox is newly installed.
